This is the core of your mortgage. Interest is the cost of borrowing, while principal pays down your balance. We calculate this using standard amortization formulas.
California property taxes are strictly regulated by Prop 13. We've auto-filled the rate based on your selected county, but Mello-Roos fees may apply in new developments.
Don't forget closing costs! In California, these typically range from 2% to 5% of the purchase price. This includes title insurance, escrow fees, and prepaid items. Use our affordability calculator to see your total cash needed including closing costs.
Additional tools to help you plan your California home purchase
Buying a home in California requires careful financial planning due to the state's unique housing market and property tax regulations. This California mortgage calculator helps you estimate your complete monthly payment including Principal, Interest, Taxes, and Insurance (PITI), along with California-specific costs like PMI and Mello-Roos assessments. Whether you're looking to purchase your first home or refinance your existing mortgage, understanding your true monthly payment is critical.
Unlike generic mortgage calculators, this tool accounts for California's Proposition 13 tax protections, county-specific property tax rates ranging from 1.0% to 1.3%, and the state's conforming loan limits of $806,500 in most counties (higher in expensive areas). Whether you're buying in Los Angeles, San Francisco, San Diego, or any of California's 58 counties, you'll get accurate payment estimates based on your exact location. Pair this calculator with our California Home Affordability Calculator to determine your complete home buying budget.
A California mortgage calculator is a specialized financial tool that estimates your monthly home loan payments based on California-specific factors. While standard mortgage calculators provide basic principal and interest calculations, a California-focused calculator incorporates the state's unique housing market characteristics, including:
This calculator provides California homebuyers with accurate monthly payment projections that account for the true cost of homeownership in the Golden State, helping you make informed decisions about how much house you can afford.
Follow these steps to get an accurate estimate of your monthly California mortgage payment:
Input the purchase price of the California home you're considering. The median home price in California is approximately $835,000-$900,000 as of 2025, but varies dramatically by region. Bay Area homes average $1.2M-$1.5M, while Central Valley homes range from $450k-$550k. Use the slider or type the exact amount for homes between $100,000 and $3,000,000.
Enter your down payment as a dollar amount or percentage. Conventional loans require as little as 3%, FHA loans need 3.5%, and VA loans offer 0% down for eligible veterans. However, putting down 20% eliminates Private Mortgage Insurance (PMI), which can save $200-$500/month. California first-time homebuyers can access down payment assistance programs like CalHFA MyHome (up to 3.5% assistance) or California Dream For All (up to 20% shared appreciation loans).
Select between Conventional, FHA, or VA loans. Each has different down payment requirements, insurance costs, and qualification standards:
Input your estimated mortgage interest rate and select your loan term (15, 20, or 30 years). Note: Interest rates change daily and vary significantly based on your credit score, down payment, loan type, and overall financial profile. A 30-year mortgage has lower monthly payments but pays more interest over time. A 15-year mortgage builds equity faster and saves significantly on interest but requires higher monthly payments.

Choose your target county from all 58 California counties. This automatically applies the correct property tax rate. Property taxes in California are based on 1% of assessed value (Proposition 13 base rate) plus local bonds and assessments. Counties with the lowest effective rates include Modoc (1.02%) and Alpine (1.04%), while counties like Alameda (1.25%) and Contra Costa (1.23%) have higher rates due to local bonds.
Your credit score significantly impacts your interest rate and PMI costs. Choose your score range (620-679, 680-699, 700-719, 720-739, 740-759, 760+). Borrowers with 760+ credit qualify for the lowest rates and PMI (if applicable). A 100-point credit score difference can cost $200-$400/month in higher interest and PMI charges on a $750,000 California home loan.
After entering all information, the calculator instantly displays your estimated monthly payment with a complete breakdown of principal, interest, property taxes, homeowners insurance, and PMI (if down payment is below 20%).
Your total monthly mortgage payment in California consists of several components, commonly referred to as PITI plus additional costs:
This is the core loan repayment portion of your monthly payment. The principal and interest (P&I) amount depends on your loan amount, interest rate, and term. In the early years, most of your payment goes toward interest. By the midpoint of your loan, principal and interest split more evenly. In the final years, most goes toward principal. Your actual rate varies based on credit score, down payment, and market conditions—rates change daily. Use our amortization schedule feature to see this breakdown year by year. Contact us for your personalized rate quote.
California property taxes are governed by Proposition 13 (passed in 1978), which limits your base property tax to 1% of assessed value. Additional local bonds and assessments bring most California counties to effective rates of 1.0%-1.3%. On a $750,000 home in Los Angeles County (1.18% effective rate), you'll pay approximately $8,850/year ($738/month) in property taxes.
Proposition 13 protections mean: Your property taxes can only increase by 2% annually regardless of market appreciation. If your home value jumps from $750,000 to $900,000, your taxes only rise 2% that year. However, when you purchase a home, it's reassessed at current market value—you don't inherit the previous owner's low tax basis. New construction and major renovations (over $10,000) also trigger reassessment.
California homeowners insurance averages $1,500-$3,000 annually ($125-$250/month) depending on home value, location, and coverage. Coastal properties, homes near wildfire zones, and luxury properties cost more to insure. Standard policies cover fire, theft, and liability but exclude earthquakes and floods.
Additional California Insurance Considerations: Earthquake insurance through the California Earthquake Authority (CEA) costs $800-$3,000/year ($65-$250/month) depending on location and deductible. Wildfire insurance for homes in high-risk zones can add $2,000-$5,000/year. Many lenders require fire insurance with wildfire coverage for properties in WUI (Wildland-Urban Interface) areas.
If you put down less than 20% on a conventional loan, you'll pay PMI, typically 0.5%-1.5% of the loan amount annually ($250-$750/month on a $600,000 loan). PMI costs vary by credit score, down payment amount, and loan type. A 760+ credit score with 10% down pays approximately 0.5% annually, while a 680 credit score with 5% down pays 1.0% annually.
FHA Loans: Require upfront MIP of 1.75% (added to loan balance) plus monthly MIP of 0.55% annually. Unlike PMI, FHA MIP never cancels—you pay it for the life of the loan unless you refinance to conventional.
VA Loans: No monthly insurance, but require a VA funding fee (2.3% first-time, 3.6% subsequent use) that can be rolled into the loan.
When PMI Cancels: Conventional loan PMI automatically cancels at 78% LTV (loan-to-value) or can be requested at 80% LTV after paying down the balance or if your home appreciates.
Many California properties, especially condos, townhomes, and planned communities, charge Homeowners Association (HOA) fees ranging from $200-$800/month (some luxury buildings exceed $1,000/month). These fees cover common area maintenance, amenities (pools, gyms, landscaping), insurance for building exteriors, and sometimes utilities. HOA fees are not tax-deductible.
Mello-Roos are special taxes assessed on properties within Community Facilities Districts (CFDs), primarily in newer California developments built after 1982. These taxes fund infrastructure such as schools, parks, fire stations, roads, and utilities. Mello-Roos typically add $100-$500/month but can exceed $800/month in some developments. Unlike property taxes, Mello-Roos don't decrease as you pay down your mortgage—they're fixed annual assessments tied to the property, not your loan balance. Mello-Roos ARE tax-deductible like property taxes.
How to Find Out: Ask the seller if the property is in a CFD, check your county assessor's website, or look for Mello-Roos disclosure in listing documents. Many Southern California developments (Riverside, San Bernardino counties) and newer Northern California communities have Mello-Roos.
Proposition 13, passed in 1978, revolutionized California property taxes by limiting annual increases to 2% regardless of market appreciation. This makes California mortgage payments more predictable than states where property taxes can spike 10-20% in hot markets.
Key Prop 13 Rules:
The Federal Housing Finance Agency (FHFA) sets conforming loan limits annually. For 2025, most California counties have a limit of $806,500. High-cost counties have higher limits:
Loans above these limits are considered "jumbo loans" and typically require higher credit scores (700+), larger down payments (10-20%), and more extensive documentation. Jumbo rates are often 0.25%-0.75% higher than conforming rates.
California's housing market varies dramatically by region. As of early 2025:
California offers several programs to help first-time and low-to-moderate income buyers with down payments:
These programs can reduce your required down payment from $150,000 to $75,000-$100,000 on a $750k home, making California homeownership accessible sooner. A Good Lender is a CalHFA-approved lender. Schedule a free consultation to discuss down payment assistance program availability and determine your eligibility for these life-changing programs.
Conventional loans are the most common mortgage type in California, offered by private lenders and backed by Fannie Mae or Freddie Mac. Requirements: 620+ credit score (680+ for best rates), 3-20% down payment, debt-to-income ratio below 43-45%. Conforming loan limit: $806,500 in most counties. Benefits: PMI cancels at 20% equity, flexible loan terms, lowest rates for qualified borrowers. Best for: Buyers with good credit and stable income. See if you qualify for a conventional loan with A Good Lender's simple online application.
Federal Housing Administration (FHA) loans are popular among California first-time buyers due to lenient credit requirements. Requirements: 580+ credit score (500-579 with 10% down), 3.5% minimum down payment, DTI up to 43-50%. Loan limits: $498,257 (low-cost counties) to $1,149,825 (high-cost counties like Santa Clara). Costs: Upfront MIP of 1.75% plus monthly MIP of 0.55% for loan life. Benefits: Low down payment, easier qualification, flexible credit standards. Drawbacks: MIP never cancels unless you refinance. Best for: Buyers with lower credit scores or limited savings.
VA loans help California veterans, active-duty service members, and eligible spouses buy homes with no down payment. Requirements: Valid Certificate of Eligibility (COE), 580-620+ credit (lender-dependent), primary residence only. Loan limits: No maximum (can borrow up to appraised value with no down payment). Costs: VA funding fee of 2.3% first-time use, 3.6% subsequent use (can be rolled into loan). No PMI or MIP. Benefits: 0% down, no monthly mortgage insurance, competitive rates, lenient credit standards. Best for: Veterans and military personnel buying in expensive California markets.
Jumbo loans finance homes above conforming limits ($806,500+ in most California counties). Requirements: 700+ credit score, 10-20% down payment (some lenders require 20% for loans over $1.5M), DTI below 43%, extensive documentation (2 years tax returns, W-2s, bank statements). Rates: Typically 0.25%-0.75% higher than conforming loans. Benefits: Finance expensive California properties, some lenders offer portfolio products with flexibility. Best for: Buyers purchasing high-value homes in Bay Area, Los Angeles, Orange County, and other expensive markets.
USDA loans offer 0% down payment for eligible rural and suburban California properties. Requirements: Property must be in USDA-eligible area (check USDA eligibility map), income limits apply ($103,500-$137,000 depending on household size and county), 640+ credit score. Costs: Upfront guarantee fee of 1% plus annual fee of 0.35%. Benefits: 0% down, low rates, lenient credit. Best for: Buyers in eligible rural California areas like parts of Shasta, Butte, Humboldt, and Kern counties.
The down payment is one of the biggest barriers to California homeownership due to high home prices. Here's what you need to know:
Putting 20% down eliminates PMI, saving $200-$500/month on a typical California home. On a $750,000 home with 10% down, you'll pay approximately $350/month in PMI. Over 5 years before PMI cancels, that's $21,000. By putting 20% down, you avoid this cost entirely. Additionally, 20% down qualifies you for better interest rates (0.125%-0.25% lower) and makes your offer more competitive in California's fierce housing market.
Don't forget closing costs when budgeting for a California home purchase. Closing costs typically range from 2-4% of home price ($15,000-$30,000 on a $750k home) and include appraisal ($500-$800), title insurance ($1,500-$3,000), escrow fees ($2,000-$4,000), loan origination fees (0-1%), prepaid property taxes and insurance, and recording fees.
Total Cash Needed Examples:
Always maintain 2-6 months of reserves after closing for emergencies and California's higher cost of living.
Your credit score is one of the most important factors in determining your California mortgage rate and monthly payment. Here's the breakdown:
Important: Interest rates change daily and everyone's situation is different. The examples below are for illustration purposes only and do not represent current rates. Your actual rate depends on credit score, down payment, loan type, property type, and market conditions. Contact A Good Lender or call (510) 589-4096 for your personalized rate quote.
Generally, better credit scores qualify for lower interest rates. Here's an example of how credit score tiers typically affect monthly payments (for illustration only):
Over 30 years, a 100-point credit score difference can cost tens of thousands to over $100,000 in additional interest on a California mortgage. Improving your credit before buying can dramatically reduce your long-term costs.
If you put less than 20% down on a conventional loan, PMI rates also vary by credit score:
If your credit score is below 700, consider these steps before applying for a California mortgage:
Improving your credit score from 680 to 740 can save you $200-$300/month on a California mortgage—worth the effort. Not sure where your credit stands? Apply for pre-approval and our loan officers will review your credit and provide personalized recommendations to optimize your rate before you start home shopping.
Lenders typically limit your monthly housing costs (PITI) to 28% of gross monthly income. For California's high home prices, this means:
Total debt payments (housing + car loans + student loans + credit cards + other debts) shouldn't exceed 43-45% of gross monthly income. California lenders may approve up to 50% DTI for strong borrowers (760+ credit, significant reserves, stable employment). If you have minimal debt, you can afford more house. If you have $1,000/month in car and student loan payments, your housing budget decreases accordingly.
Based on 28% housing ratio with 10% down, 20% down scenarios:
California's regional income differences matter. Bay Area median household income is $140,000, making $1.2M median home prices feasible for many dual-income households. Central Valley median household income is $70,000, aligning with $400k-$500k median home prices. Consider regional income levels when evaluating affordability.
For a detailed affordability analysis based on your income, debts, and savings, use our California Home Affordability Calculator.
Use this calculator before you start touring homes to understand what monthly payment you're comfortable with. Test different home prices, down payments, and loan types to find your optimal scenario. This prevents falling in love with a home you can't afford and saves time by focusing on properties in your budget. Once you know your target monthly payment, get pre-approved to lock in your rate and strengthen your offers in California's competitive housing market.
After getting pre-approved, use this calculator to compare your lender's estimated payment with the calculator's projection. If there's a significant difference, ask your lender to explain. Sometimes lenders underestimate property taxes, insurance, or HOA fees. Knowing the full payment helps you budget accurately.
Test multiple scenarios: 3% down vs 20% down, 30-year vs 15-year mortgage, conventional vs FHA, different California counties. See how each choice affects your monthly payment. This helps you make informed decisions about trade-offs (smaller down payment = higher monthly payment, or vice versa).
Use the calculator to see exactly how much monthly payment you save by increasing your down payment. If putting 20% down saves you $400/month in PMI, is it worth depleting your savings? Or is 10% down with some PMI a better choice to keep emergency funds intact? The calculator helps you visualize the trade-offs.
Compare conventional, FHA, and VA loan monthly payments side-by-side. FHA's low down payment might seem attractive, but lifetime MIP makes it more expensive long-term. VA's 0% down is great for eligible veterans. Conventional offers flexibility. The calculator shows total costs for each option.
If you currently have a California mortgage, use this calculator to estimate your new payment after refinancing. If rates have dropped or your home has appreciated (allowing you to eliminate PMI), calculate potential monthly savings. Factor in refinance closing costs (typically $3,000-$6,000) to determine break-even point.

For a $750,000 house in California with 20% down ($150,000), your monthly payment typically ranges from $4,800-$5,200+ depending on your interest rate, county, and insurance costs. This includes: Principal & Interest (varies by rate—rates change daily based on credit score and market conditions), Property Taxes ($625-$813 based on county rate of 1.0-1.3%), Homeowners Insurance ($200-$250+), and no PMI since you put 20% down. With 10% down, add $300-$400/month for PMI. Use our calculator above to see estimated payments, then contact A Good Lender at (510) 589-4096 for your personalized rate quote—everyone's situation is different and rates update daily.
To afford a $1 million home in California, you typically need a gross annual income of $270,000-$280,000 using the standard 28% housing ratio. With 20% down ($200,000), your monthly payment would be approximately $6,400-$6,700 including PITI (P&I: $5,189, Taxes: $835-$1,085, Insurance: $250-$300). At $275,000/year income ($22,917/month), 28% equals $6,417 for housing—which covers the payment comfortably. However, many California lenders approve up to 43-45% debt-to-income for strong borrowers (740+ credit, stable employment, low debts), meaning you could qualify with $175,000-$190,000 income if you have minimal car loans or student debt. Your credit score (affects rate), down payment size (more down = lower payment), and existing debts significantly impact qualification. Consider using a co-borrower to combine incomes if needed. Use our <a href='/california-home-affordability-calculator' style='color: #7d1d1d; text-decoration: underline;'>affordability calculator</a> to see exactly what you can afford based on your income.
Proposition 13 (passed in 1978) limits your California property tax to 1% of assessed value plus local bonds/assessments, and caps annual tax increases at 2% regardless of how much your home appreciates. This means if you buy a $750,000 home today, your base property tax is $7,500/year ($625/month). Even if your home value jumps to $900,000 next year, your tax only increases by 2% to $7,650/year. This makes California mortgage payments more predictable than other states where property taxes can spike dramatically. However, when you buy a home, it's reassessed at current market value—you don't inherit the previous owner's low tax base. New construction and major renovations also trigger reassessment.
Mello-Roos are special taxes on properties in Community Facilities Districts (CFDs), primarily in newer developments built after 1982. These taxes fund infrastructure like schools, parks, fire stations, and roads. Mello-Roos typically add $100-$500 per month to your payment, though some areas can be $800+. Unlike property taxes, Mello-Roos don't decrease when you pay down your mortgage—they're fixed annual assessments (usually 15-30 year bonds) tied to the property, not your loan. Mello-Roos ARE tax-deductible like property taxes. Before buying, ask the seller or check your county assessor's website for CFD disclosures. These fees significantly impact affordability but are common in desirable new developments throughout California.
Earthquake insurance is NOT required by lenders in California, but it's highly recommended depending on your location and risk tolerance. Standard homeowners insurance doesn't cover earthquake damage. The California Earthquake Authority (CEA) offers policies ranging from $800-$3,000+ annually ($65-$250/month) based on home value, location, construction type, and deductible chosen (typically 10-25% of coverage). Homes near major fault lines cost more. Most buyers in high-risk zones budget $100-$200/month for earthquake coverage. While not included in standard PITI calculations, smart California buyers factor this into total housing costs. If you're buying a $750,000 home, budget $150/month extra for comprehensive earthquake protection—it could save you hundreds of thousands after a major quake.
California offers several down payment assistance programs in 2025: 1) CalHFA MyHome Assistance Program provides 3.5% down payment assistance (up to $26,250 on $750k home) as a deferred-payment junior loan with 0% interest, no monthly payments, due when you sell/refinance. 2) California Dream For All (currently closed for applications but accepting voucher submissions from previous rounds; check CalHFA website for next funding announcement) offers down payment help up to 20% as a shared appreciation loan for first-generation homebuyers. 3) Golden State Finance Authority provides grants/loans up to 3-5% for qualified buyers. 4) Local city/county programs offer additional $10,000-$50,000 in some areas. Eligibility typically requires: first-time buyer status, income limits ($150k-$180k depending on county), primary residence only, and completion of homebuyer education. These programs can reduce your down payment from $150,000 to $75,000-$100,000 on a $750k home, making homeownership accessible sooner. Contact a CalHFA-approved lender for current program availability.
Yes, you can buy a California home with just 3% down using conventional 97% LTV loans or FHA loans (3.5% down). On a $750,000 home with 3% down ($22,500), you'd borrow $727,500 and pay PMI of approximately $400-$550/month depending on your credit score. With a 720+ credit score, expect $425/month (0.7% annual rate). Below 680 credit, PMI jumps to $545/month (0.9% rate). FHA loans with 3.5% down require both upfront MIP (1.75% = $12,731 added to loan) plus monthly MIP of $335/month (0.55% annual rate) for the life of the loan—FHA MIP never cancels unless you refinance. Conventional PMI cancels automatically at 78% LTV or when you request it at 80% LTV. Total monthly payment with 3% down conventional: approximately $5,700-$6,000 including PITI and PMI. You'll need strong income ($170,000+) and good credit (680+) to qualify with low down payment.
With $150,000 annual income ($12,500/month gross), you can afford approximately $3,500/month for housing using the 28% rule, or up to $5,375/month if approved at 43% debt-to-income (requires strong credit and minimal debts). At 28%: You can afford a $575,000-$625,000 home with 10-20% down, resulting in a $3,200-$3,500 monthly payment including PITI and PMI. At 43% (if you have low other debts): You can afford a $850,000-$900,000 home with 20% down, though you'd need $170,000-$180,000 saved for down payment. Most $150k earners comfortably afford $600,000-$700,000 homes with $60,000-$100,000 down (10-15%). Your exact buying power depends on: credit score (affects rate), existing debts (car/student loans), down payment size, and property tax rate in your target county. Use our calculator to model different scenarios.
Minimum credit scores for California home loans in 2025: Conventional loans require 620+ (though 680+ gets better rates), FHA loans accept 580+ (500-579 allowed with 10% down), VA loans need 580-620+ depending on lender, and Jumbo loans (over $806,500 in most CA counties) require 700+. However, higher scores save substantial money—better credit qualifies for lower interest rates, which can save hundreds per month and tens of thousands over the life of the loan. Before buying in California's expensive market, improve credit to 720+ if possible. Note: Rates change daily and vary by individual situation. Contact A Good Lender at (510) 589-4096 for your personalized rate quote based on your specific credit profile. Check your score free at AnnualCreditReport.com.
Down payment needed for a $750,000 California home varies by loan type: 3% down = $22,500 (Conventional 97), 3.5% down = $26,250 (FHA), 5% down = $37,500 (Conventional), 10% down = $75,000 (Conventional), 15% down = $112,500 (Conventional), 20% down = $150,000 (Conventional, avoids PMI). PLUS closing costs: Budget additional 2-4% ($15,000-$30,000) for closing costs including appraisal, title insurance, escrow fees, and prepaid taxes/insurance. Total cash needed: $37,500-$180,000 depending on down payment percentage. Many California buyers use down payment assistance programs to reduce the 20% requirement—see CalHFA programs that provide up to $26,250 in deferred-payment assistance. With 10% down ($75k) plus assistance ($26k), you're effectively at 18% down and only need $90,000 total saved.
Average California monthly housing costs in 2025 vary dramatically by price point: $500,000 home: $3,200-$3,600/month total (P&I: $2,600, Taxes: $420-$545, Insurance: $150-$200, PMI if <20% down: $200-$300). $750,000 home: $4,800-$5,400/month total (P&I: $3,890, Taxes: $625-$815, Insurance: $200-$250, HOA: $0-$300, PMI if <20% down: $300-$450). $1,000,000 home: $6,400-$7,200/month total (P&I: $5,185, Taxes: $835-$1,085, Insurance: $250-$350, HOA: $0-$500). Add optional costs: Mello-Roos ($100-$500/month in newer areas), Earthquake insurance ($100-$250/month), Maintenance reserve ($200-$400/month). California homeowners typically spend 25-30% of gross income on housing—higher than the national average due to elevated home prices but offset by higher salaries and Prop 13 tax protections.
The average California mortgage payment in 2025 is approximately $5,200-$5,800+ per month based on the median home price of $835,000-$900,000. This estimate assumes 10-15% down payment, 30-year term, and includes PITI plus PMI. However, your actual payment depends heavily on your interest rate, which changes daily and varies by credit score, down payment, and lender. Regional variations: Bay Area median: $6,500-$9,000+/month (median price $1.2M-$1.5M), Southern California coastal: $5,000-$6,500+/month (median price $850k-$1.1M), Inland Empire: $3,500-$4,200/month (median price $600k-$750k), Central Valley: $2,400-$3,200/month (median price $450k-$550k). Use our calculator above for estimates, then contact A Good Lender at (510) 589-4096 for your exact payment based on current rates—everyone's situation is different.
