Principal and Interest Calculator (Amortization)

How much of your mortgage is going to
principal and interest?

The InfoChoice Principal & Interest Breakdown Calculator makes it easy to see how much of your mortgage payment is going to principal and interest every month.

Just enter the loan amount, term length, interest rate and any repayments to get a complete breakdown of where your mortgage payments are going. It also shows you how much principal versus interest has been paid to date, so you can see how much equity you've built up.

As you can see, most of your payment goes to interest in the early years of your loan, as the principal balance is paid off over time.
