California Mortgage Refinance Calculator
California homeowners refinancing in 2026 deal with loan sizes most of the country never sees — median home prices above $800,000 in the Bay Area and over $650,000 statewide. The good news: California charges no mortgage recording tax, and Proposition 13 protects your property tax base — refinancing does not trigger a reassessment, so your property tax stays the same.
The key variable that changes your calculator results is whether your loan is standard conforming, high-balance conforming, or jumbo — because each category carries different rates. This guide walks you through what to enter for accurate California refinance numbers.

What to Enter in the Calculator for a California Refinance
Your current balance determines which rate category applies. Standard conforming (≤$766,550 in most CA counties): lowest rates. High-balance conforming (up to $1,149,825 in high-cost counties): slightly higher rates than standard. Jumbo (above county limit): higher rates, stricter qualification. The refinance calculator works with all three — just make sure your lender quote matches your loan category.
If your balance has crossed a conforming limit boundary (e.g., from $800K down to $766K through payments), you may now qualify for a lower rate tier. Check your current balance on your mortgage statement and compare it to your county's conforming limit.
If you are near a conforming loan limit, ask your lender to quote both a conforming refi (possibly requiring a small paydown to reach the limit) and a jumbo refi at your current balance. The difference in rate is sometimes large enough to justify paying down the balance at closing.
California has no mortgage recording tax, which saves $1,500–$15,000 compared to New York. Your closing costs include: lender origination (0–1%, highly negotiable), appraisal ($600–$800 for high-value homes), title insurance (scales with loan size), and recording fees (~$300). Total typically runs $6,000–$12,000 depending on loan size.
When you refinance in California, there is no change of ownership — Prop 13's reassessment protection stays intact. Your property taxes remain based on your original purchase price (or last reassessment), increased by no more than 2% per year. Do not adjust your property tax estimate in the calculator when modeling your post-refinance PITI.
Two California Refinance Scenarios
Los Angeles — $680,000 Loan
Sacramento — $430,000 Loan
California's no-recording-tax advantage produces clean break-even math. Both scenarios assume 30-year term. Sacramento's standard conforming loan qualifies for lower rates than the LA high-balance loan.
California Conforming Loan Limits by County Type
Knowing your loan limit is the first step to getting the right rate quote. California has the widest variation in conforming limits of any state.

Frequently Asked Questions
Does refinancing trigger a property tax reassessment in California?
No. Proposition 13 protects your assessed value — refinancing does not constitute a change of ownership and does not trigger reassessment. Your property tax base stays the same regardless of how many times you refinance. Only an outright sale or new construction triggers a new assessment.
What is a high-balance conforming loan in California?
A loan above the standard conforming limit ($766,550) but below the county's high-cost ceiling (up to $1,149,825 in the most expensive California counties). These qualify for Fannie Mae/Freddie Mac programs at slightly higher rates than standard conforming, but much lower rates than true jumbo loans. Many California homeowners refinancing large balances are in this category.
How much do California refinance closing costs typically run?
California has no mortgage recording tax. Typical total: $6,000–$12,000 depending on loan size and lender origination fees (0–1%). Larger loans have proportionally higher title and escrow costs. No attorney is required at closing — title companies handle the process. Lender origination fees are the most negotiable line item.
How does community property status affect my California refinance?
Both spouses must typically sign the deed of trust at closing, even if only one borrower is on the loan. If applying with one spouse to use the stronger credit score, the other spouse still signs certain documents. Community property means your spouse's debts may be considered in underwriting even if they are not on the loan. Discuss your specific situation with your lender before applying.
What break-even period should I expect for a California refinance?
California's high loan balances produce large monthly savings per point of rate reduction, which shortens break-even. On a $700,000 loan with a 0.75% rate drop, savings are ~$333/month. With $10,000 in closing costs (no recording tax), break-even is about 30 months. Use the break-even calculator for your exact numbers.
