California Mortgage Calculator
Estimate your full monthly payment — principal, interest, taxes, and insurance — for conventional or FHA loans.
Estimate your full monthly payment — principal, interest, taxes, and insurance — for conventional or FHA loans.
Your full payment includes principal and interest, property taxes, homeowners insurance, mortgage insurance when required, and HOA dues. Principal reduces your debt; interest pays for borrowing. The other charges do not reduce the loan balance.
Illustrative example, not a quote: a $600,000 home, 3.5% FHA down payment, 30-year term and 6.5% fixed interest rate. We assume annual property taxes of 1.25%, insurance of 0.35%, and no HOA dues. Actual taxes, special assessments and insurance vary by property; check the county bill and an insurance quote.
The down payment is $21,000. The base loan is $579,000; financing $10,133 in upfront FHA mortgage insurance brings the financed balance to $589,133. Upfront insurance is separate from monthly mortgage insurance.
Your down payment is not all your cash to close. Separate example: $21,000 down + $12,000 in costs and prepaids − $5,000 earnest-money deposit already paid − $3,000 in permitted credits = $25,000 still due at closing. These are illustrative amounts, not guaranteed charges.

For a purchase, use this mortgage payment calculator with the home price, down payment and housing expenses. To replace an existing loan, use the mortgage refinance calculator: it compares your outstanding balance, rate and years remaining with a new term and uses closing costs to estimate break-even. A smaller payment does not guarantee lower total interest.
For estimating a home purchase payment, yes: both names describe a tool that uses the home price, down payment, interest rate and term to calculate principal and interest. This calculator also lets you include property taxes, homeowners insurance, mortgage insurance when applicable and HOA dues. Review those expenses to compare the full monthly cost, not just the loan payment. The result does not determine how much a lender will approve.
It depends on more than the home price. Divide the full housing payment plus your other monthly debts by a planning debt-to-income ratio, such as 43%. For example, $4,000 housing + $500 debts, divided by 0.43, implies about $10,465 gross monthly income. This is not approval; the program and file review determine the applicable limit.
Enter the home price, down payment, interest rate and loan term. Then check property taxes, homeowners insurance and HOA dues. You can calculate without signing up; requesting a personalized review is optional. The rate you enter is a calculation assumption, not a rate offer or APR.
For a fully amortizing fixed-rate loan: M = P × r × (1 + r)^n ÷ ((1 + r)^n − 1). P is the financed loan balance, r is the annual interest rate divided by 100 and then by 12, and n is the number of monthly payments. For 30 years, n = 360. At zero interest, M = P ÷ n. This formula calculates principal and interest only; add taxes, insurance and HOA dues for the full payment.
The principal-and-interest formula is the same, but property taxes, special assessments, insurance and HOA dues depend on the property. Do not assume the seller's tax bill will be yours after purchase. Confirm the assessed value and local charges with the county, and get an insurance quote. The example's 1.25% tax assumption is not a uniform California tax rate.
No. A mortgage payment calculator starts with a home price and estimates the monthly cost. An affordability calculator starts with gross income, other monthly debt payments and down payment to estimate a possible price. The same income can support different budgets depending on debts, taxes and insurance. Neither calculator replaces a loan review.
No. A $350,000 home with 20% down requires a $70,000 down payment and leaves a $280,000 base loan. A $350,000 mortgage means you borrow $350,000, not that the home costs that amount. Financed charges, where allowed, can increase the balance; closing costs are separate from the down payment.
