Understanding Mortgage Amortization
Amortization refers to the process of gradually paying off a debt over a set period through regular principal and interest payments. With a mortgage, your monthly payments are initially skewed towards interest. As time progresses and your principal balance decreases, a larger portion of your payment goes towards reducing the principal.
Our calculator generates an amortization schedule, offering insights into:
- Your exact monthly payment amount.
- How much of each payment goes towards principal vs. interest.
- The total interest you will pay over the entire loan term.
- The total cost of your mortgage, including principal and interest.
Using this calculator allows you to experiment with different loan scenarios, interest rates, and loan terms to find a mortgage that best fits your financial goals.

Mortgage Amortization Formula Explained
The standard formula used to calculate a fixed-rate mortgage payment is:
M = P [ i(1 + i)n ] / [ (1 + i)n – 1]
Where:
- M = Your monthly mortgage payment
- P = The principal loan amount (the initial amount borrowed)
- i = Your monthly interest rate (the annual interest rate divided by 12)
- n = The total number of payments (the loan term in years multiplied by 12)
This formula determines the fixed payment required each month to pay off both the principal and the accrued interest over the loan term. The calculator performs these calculations instantly, taking into account the compounding interest and the gradual reduction of your principal balance.
