Balance payoff comparison

This chart shows how your loan balance drops over time with and without extra monthly payments.

What is extra mortgage payment?

Extra mortgage payment means paying more than your required monthly amount. That extra money usually goes toward principal, which lowers future interest and helps you pay off the loan faster.

How much can you save?

Making extra payments on your mortgage can save you thousands in interest. Even a small monthly increase can significantly reduce your loan term over time.

Should you pay off early?

Paying off early can make sense if your goal is to reduce interest costs and become debt-free sooner. The best choice depends on your cash flow, savings, and other financial priorities.

How does this calculator work?

It first calculates your standard mortgage payment. Then it simulates the same loan with an extra payment added every month and compares the total interest, total payoff period, and total amount paid.

Does extra payment always reduce total interest?

In a standard amortizing mortgage, extra principal payments usually reduce total interest because your balance drops faster. Check your lender terms to make sure extra payments are applied to principal.
