California Mortgage Calculator guide
The California mortgage calculator is built for buyers and refinancers in one of the nation’s most expensive housing markets. With median home prices well above the national average, we prefill a $750,000 purchase, 20% down, and a 6.8% rate to reflect current conditions. California’s Proposition 13 caps property tax increases, so effective rates on resale homes are often lower than in other states—we use 1.1% as a baseline, but you can adjust for your county and purchase price.
Insurance costs in California can be significant, especially in wildfire-prone areas. We default to $2,400 annually; increase it if you are in a high-risk zone or expect higher premiums. HOA dues are common in condos and planned communities—add them in the HOA field to see the full carrying cost. Extra payments and biweekly schedules help many California borrowers pay down principal faster and reduce total interest on large loan balances.
The amortization table and charts show how your payment breaks down over time. Use the yearly view for tax planning, since mortgage interest deductions can be valuable at California income levels. The calculator runs entirely in your browser, stores your last inputs locally, and works offline when installed as a PWA.
