Free online mortgage calculator
This mortgage calculator helps you estimate what a home loan will really cost. Enter the home price, your down payment, the annual interest rate and the loan term, and it instantly works out your monthly principal-and-interest payment along with the total interest and total amount you will pay over the life of the loan. It is a fast way to compare scenarios — a larger down payment, a shorter term or a lower rate — and see how each choice changes your monthly budget.

Every calculation runs directly in your browser. Nothing you type is uploaded, saved or shared, so you can plan freely and close the tab knowing nothing was stored. Keep in mind the result is an estimate of principal and interest only: it excludes property taxes, homeowners insurance, HOA dues and mortgage insurance, and it is not financial advice.
Frequently asked questions
How is the monthly payment calculated?
We use the standard amortization formula on the loan amount (home price minus down payment), your monthly interest rate and the total number of monthly payments. The figure covers principal and interest only.
Does this include taxes and insurance?
No. The estimate excludes property taxes, homeowners and mortgage insurance, and any HOA fees. Your actual monthly bill will be higher, and this tool is not financial advice.
