Mortgage Calculator

Estimate your monthly repayment and the total interest you'll pay over the life of the mortgage.

This is a repayment mortgage estimate assuming a fixed interest rate for the whole term. Real mortgages usually have a fixed-rate deal for a few years, then move to a variable rate, so your actual payments may change.

How mortgage repayments work

On a repayment mortgage, each monthly payment covers the interest for that month plus a slice of the amount you borrowed. Early on, most of your payment goes on interest; later, more goes on the balance. A longer term lowers your monthly payment but increases the total interest you pay. Even a small change in the interest rate can make a big difference over 25 years.
