Clearer numbers for a major financial decision.

The Home Loan Calculator is a free planning tool for estimating monthly principal and interest, total repayment, total interest, and the effect of an extra payment.

Why we built it

Mortgage decisions involve more than finding the smallest monthly payment. The interest rate, loan term, principal, fees, and timing of extra payments can materially change the long-term cost. We built this calculator to make those tradeoffs easier to see and compare.

How the calculator works

Calculations use the standard fixed-rate amortization formula and run directly in your browser. The tool produces an estimate based on the values you provide; it does not make lending decisions, check eligibility, or replace a lender's official loan estimate.

Our principles

• Keep the calculator free and straightforward.
• Explain assumptions and exclusions clearly.
• Keep entered figures in the browser unless you deliberately share a URL.
• Avoid presenting estimates as personalized financial advice.
