About LoanCalc
LoanCalc is a free toolkit of loan calculators: mortgage payments, home affordability, refinance break-even, amortization schedules, student loan payoff strategies, and biweekly payments.
Why it exists
Borrowing decisions are some of the biggest financial decisions people make, and the math behind them shouldn't be a black box. These calculators show the same amortization math lenders use — monthly payments, total interest, payoff timelines — in plain language, for free.
How it's built
Every calculation runs entirely in your browser. There's no account, no tracking of your inputs, and nothing you type is sent to or stored by us. The site is supported by advertising, which keeps every calculator free.
What it isn't
LoanCalc is an educational tool, not a lender and not a financial advisor. Results are estimates based on the numbers you enter. For decisions about borrowing, talk to a licensed mortgage or financial professional.
