PlainFigure

Mortgage calculators for expensive home decisions

Compare lender quotes, affordability, refinance timing, home equity borrowing, ownership costs, repairs, and payoff tradeoffs before committing to a home decision.

Start with the mortgage question you need to answer

Mortgage decisions are rarely just about the lowest advertised rate. Closing costs, inspection findings, points, PMI, taxes, insurance, time in the home, and cash-to-close can change the best answer.

These calculators run in your browser and are meant to make lender quotes easier to compare. They are educational tools, not financial advice or lender recommendations.

Reviewed May 2026. Mortgage math uses standard amortization formulas with page-level assumptions and source notes. Start with the methodology overview or affiliate disclosure if you want to see how PlainFigure separates calculator results from partner links.
