Calculate your monthly payment, total interest, and amortization.
Principal vs interest per year
Our mortgage calculator helps you understand the true cost of buying a home before you sign anything. Enter your property price, down payment, interest rate, and loan term to instantly see your monthly payment, total interest paid over the life of the loan, and the full amount you will repay. The loan-to-value ratio gives you a quick sense of your equity position from day one.
The year-by-year amortization chart shows exactly how each payment splits between principal and interest. In early years most of your payment covers interest, but over time a larger share goes toward reducing the balance. Understanding this shift helps you evaluate whether extra payments or refinancing could save you money over the long run.
Even a small difference in interest rate can add up to thousands over a 25-year mortgage. Try adjusting the rate and term to see how a shorter loan period increases monthly payments but dramatically cuts total interest. This side-by-side comparison is one of the best ways to decide between a 15-year and 30-year mortgage offer.

For a loan amount of $300,000 with a down payment of $60,000 (financed principal $240,000), at an interest rate of 3.5% over a 20-year term, the estimated monthly payment is $1,391.9, with total interest paid of approximately $94,056.8 over the life of the loan.
