Buying a home is one of the biggest financial decisions you will ever make. Our suite of free calculators is designed to give you clarity at every step of the process — from figuring out what you can afford, to estimating your monthly payments, to comparing markets across different cities.
Each calculator starts from example inputs you can change (price, down payment, interest rate), so enter your own figures for your own numbers. The Affordability Calculator applies California qualifying rules. The Mortgage Calculator breaks down principal, interest, property taxes, and insurance so you can see the true cost of ownership. The Rent vs Buy Calculator models both scenarios over your chosen time horizon, factoring in equity growth, opportunity cost, and investment returns to find your break-even point. And the City Comparison Tool puts two markets side by side with the figures each city's real estate board publishes, census demographics and published rents.
All tools are free to use and require no sign-up. Data is refreshed regularly from MLS® listings and public records.
