When you first start making mortgage payments, it can be surprising to see how much goes toward interest and how little goes toward reducing the loan balance. This is a normal part of how most mortgages are structured and is known as amortization. Each monthly payment is divided between interest and principal, with the balance shifting over time.
Mortgage interest is calculated based on your remaining loan balance. At the beginning of the loan, your balance is at its highest, so the amount of interest charged is also higher. As you make payments and reduce the principal balance, the amount of interest owed each month generally decreases.
Because your required payment is typically structured to remain consistent on a fixed-rate mortgage, the portion going toward principal gradually increases as the interest portion decreases. Over the life of the loan, this creates a predictable payment schedule that eventually pays the mortgage off in full.
This is also why making additional principal payments early in the loan can have a greater impact on your total interest costs. When you reduce the loan balance sooner, you also reduce the amount of money on which future interest is calculated. Even relatively small additional payments can add up over time, depending on the loan terms and how long you keep the mortgage.
Understanding how your payment is divided can help you make more informed decisions about your mortgage. Your loan terms and overall financial goals can help determine what approach makes the most sense for you.
