Mortgage Calculator

Looking to take out a mortgage sometime soon?

Knowing the size mortgage you can afford could help you to find the home to fit your budget—and your dreams. Use this calculator to determine your mortgage payment amount and the impact of optional additional prepayments.

The amortization schedule breaks down the principal and interest portion of each mortgage payment.

Mortgage Payment Calculator

Enter the purchase price

Enter your down payment, the amount of money you will contribute at the beginning to put towards the home purchase.

Most lenders require mortgage loan insurance if your down payment is less than 20% of the purchase price. The lender will obtain mortgage insurance and typically, the premium will be added to your mortgage.

Enter an interest rate

Enter the amortization period. This is the total length of time you’ll take to pay off your mortgage in full. Most people choose 25 or 30 years.

Enter the mortgage term. This is how long you agree to have the mortgage with the lender at a specific interest rate, payment terms and conditions.

Enter a payment frequency.

Enter the date your first mortgage payment is due. If you are unsure, estimate a date.

Mortgage payment amount:

Additional mortgage payments (optional)

Your mortgage may allow you to make additional payments, up to certain limits.

Some mortgages allow you to make an annual lump sum payment towards the outstanding principal amount, subject to certain rules and conditions.

Some mortgages allow you to make additional monthly payments towards the outstanding principal amount. Check with your lender for rules and conditions.

Additional homeownership costs (optional)

The cost of home ownership is more than a mortgage payment. Estimate additional potential costs.
