How to Use This Calculator

Using our mortgage calculator is simple:

The calculator will display your monthly payment amount, total interest paid over the life of the loan, and a breakdown of your payments over time.

Formula Used

The mortgage payment is calculated using the standard mortgage formula:

M = P [ r(1 + r)^n ] / [ (1 + r)^n - 1 ] Where: M = Monthly payment P = Principal loan amount r = Monthly interest rate (annual rate / 12) n = Number of payments (amortization period in years × 12)

This formula accounts for the interest on the loan balance over each payment period.

Worked Example

Let's calculate a mortgage payment for a $300,000 loan with a 5% annual interest rate and a 25-year amortization period.

Monthly interest rate = 5% / 12 = 0.4167% Number of payments = 25 × 12 = 300 M = $300,000 [ 0.004167(1 + 0.004167)^300 ] / [ (1 + 0.004167)^300 - 1 ] M ≈ $1,734.36

Your monthly payment would be approximately $1,734.36.

Frequently Asked Questions

What is the difference between fixed and variable rate mortgages?

A fixed-rate mortgage has the same interest rate for the entire term, while a variable-rate mortgage's interest rate can change based on market conditions. Fixed rates typically offer more stability, while variable rates may offer lower initial rates.

How does amortization affect my mortgage payments?

The amortization period is the length of time you have to pay off your mortgage. A longer amortization period means lower monthly payments but more total interest paid over time. A shorter amortization period means higher monthly payments but less total interest paid.

What is the difference between principal and interest payments?

Principal payments reduce the amount you owe on the loan, while interest payments cover the cost of borrowing the money. In the early years of a mortgage, most of your payment goes toward interest. Over time, as the principal balance decreases, more of your payment goes toward the principal.

How do I calculate my mortgage affordability?

Mortgage affordability is typically calculated based on your income, debts, and down payment. A common rule is that your total mortgage payment (principal, interest, taxes, and insurance) should not exceed 28-36% of your gross monthly income.
