Your result, explained

Borrowing $1,020,000 costs $6,313.52 a month in principal and interest, plus $1,122.92 for property costs like tax and insurance, so you should budget $7,436.44 a month. Over the full term you would pay $1,252,868 in interest, 123% on top of what you borrowed.

Ways to make it cheaper: paying even a little extra each month cuts years off the loan; a rate just 0.5% lower saves thousands over the term, so compare lenders. Remember you need $255,000 in cash upfront.

How your mortgage payment is calculated

A repayment mortgage has a fixed monthly payment that covers the interest due that month plus a slice of the loan. Early on, most of each payment is interest. As the balance falls, more goes to the principal, which you can see in the schedule above.

The formula is P × r ÷ (1 − (1 + r)−n), where P is the loan, r the monthly interest rate and n the number of payments.
