🏠 California Mortgage Calculator

Use this California mortgage calculator to estimate your monthly home loan payment, including principal, interest, property tax, homeowner’s insurance, PMI, and HOA fees. California’s median home price hovers around $750,000—well above the national average—so understanding every component of your payment is essential before making an offer.

Adjust the home price, down payment, interest rate, and loan term to see how different scenarios affect your budget. Whether you’re buying in Los Angeles, San Francisco, Sacramento, or San Diego, this tool gives you a clear monthly cost estimate in seconds. Thanks to Proposition 13, California’s effective property tax rate is lower than most states at roughly 0.76%, but the high purchase prices mean your escrow payment can still be substantial. First-time buyers may qualify for CalHFA assistance programs that provide down payment help and below-market interest rates.

California Housing Market Overview

California consistently ranks among the most expensive housing markets in the United States. The statewide median home price sits near $750,000, but regional variation is dramatic. In the San Francisco Bay Area and parts of coastal Southern California, median prices can exceed $1,200,000, while more affordable pockets exist in the Central Valley, Inland Empire, and parts of the northern portion of the state where median prices may fall between $350,000 and $500,000.

Inventory has remained tight in many metro areas, driving competition among buyers. Despite elevated mortgage rates, demand in employment-rich regions near major tech, entertainment, and biotech hubs keeps prices firm. First-time buyers often look to outlying suburbs or consider condos and townhomes to enter the market at a lower price point.

Property Taxes in California

Thanks to Proposition 13, passed in 1978, California’s effective property tax rate is only about 0.76% of assessed value—well below the national average. Prop 13 caps the base tax rate at 1% of the purchase price and limits annual assessment increases to no more than 2% per year, regardless of how much the market value rises.

However, voter-approved local bonds and special assessments can add 0.1%–0.5% on top of the base rate, so your actual bill depends on the county and city. On a $750,000 home, expect to pay roughly $5,700–$7,500 per year in property taxes. When the home is sold, the assessed value resets to the new purchase price, which means recent buyers typically pay more than long-time owners on the same street.

California-Specific Mortgage Costs

Transfer taxes in California vary by county and city. The base county rate is $1.10 per $1,000 of the sale price, but cities such as Los Angeles, San Francisco, and Oakland levy additional transfer taxes that can reach $15 per $1,000 or higher in certain price tiers. On a $750,000 purchase, combined transfer taxes might range from $825 to $11,250 depending on location.

Closing costs in California typically run 1%–2% of the purchase price for the buyer, covering escrow fees, title insurance, lender fees, and recording charges. Buyers should also budget for a home inspection ($400–$700) and an appraisal fee ($500–$800). In many California transactions, the seller pays the county transfer tax while the buyer covers title and escrow.

Homeowner’s insurance rates have risen sharply in recent years, especially in wildfire-prone zones. Annual premiums may range from $1,200 in low-risk areas to $3,500 or more in high-fire-severity zones. Some buyers in designated fire areas must obtain coverage through the California FAIR Plan, which is the state’s insurer of last resort.

First-Time Homebuyer Programs in California

The California Housing Finance Agency (CalHFA) offers several programs designed to help first-time buyers overcome the state’s high entry costs:

  • CalHFA Conventional & FHA Loans: Below-market interest rates on 30-year fixed mortgages for buyers who meet income and purchase-price limits.
  • MyHome Assistance Program: A deferred-payment junior loan of up to 3.5% of the purchase price (or appraised value) to help cover down payment and closing costs.
  • CalHFA ADU Grant: Up to $40,000 toward the construction of an accessory dwelling unit, which can generate rental income to help offset your mortgage.
  • Forgivable Equity Builder Loan: A 10% junior loan that is forgiven after five years of owner-occupancy, effectively boosting your equity at no cost.

Income limits vary by county. In higher-cost counties such as San Francisco and Santa Clara, limits are considerably higher than in lower-cost regions. Check the CalHFA website or speak with a participating lender for current thresholds.

Tips for California Homebuyers

  • Get pre-approved before touring homes. In competitive California markets, sellers often reject offers without a pre-approval letter. Having financing lined up also helps you act quickly when inventory moves fast.
  • Factor in Prop 13 resets. Your property tax will be based on your purchase price, not the prior owner’s assessed value. Use the Percentage Calculator to estimate 1% of the price plus any local add-ons.
  • Budget for wildfire insurance. If the home is in a State Responsibility Area or a High Fire Hazard Severity Zone, expect elevated premiums or the need for a FAIR Plan policy.
  • Explore jumbo loan options. Because California prices often exceed conforming loan limits, you may need a jumbo mortgage. These loans typically require 10%–20% down and have stricter credit requirements.
  • Consider an ADU for income. California law now makes it easier to build accessory dwelling units. A backyard rental unit can generate $1,500–$3,000 per month, significantly easing your housing costs.
