Mortgage Calculator
Quick Answer
A mortgage calculator estimates your monthly home-loan payment from the loan amount, interest rate, and term. It also shows the total interest paid over the life of the loan.
What Is Mortgage Calculator?
Mortgage Calculator is a free online calculator tools tool that estimate monthly payments, total interest paid and full amortization schedule. A mortgage calculator estimates your monthly home-loan payment using the standard amortizing-loan formula. You provide the loan principal (the amount borrowed), the annual interest rate, and the term in years, and it returns the fixed monthly payment plus the total interest you will pay over the life of the loan. The formula spreads the loan into equal monthly payments that cover both interest and principal. Early payments are mostly interest; later payments pay down more principal. Two things this basic calculator does not include are property taxes and homeowner's insurance, which lenders often collect as part of an escrow payment — so your real monthly outgoings will usually be higher. It also excludes mortgage insurance (PMI), which may apply if your down payment is small. Use it to compare loan sizes, rates, and terms before you borrow. Unlike many similar tools, it runs entirely in your browser — no data is sent to any server, no account is required, and there are no usage limits. Whether you are a developer, writer, SEO professional, or casual user, this tool provides instant, accurate results without friction.
