Mortgage Extra Payment Payoff Calculator
For many homeowners, a mortgage is a decades-long financial responsibility. While monthly payments help build home equity, a large share of your payment in the early years goes toward interest. The good news is you don’t have to stick with the full 15- or 30-year plan. By making extra payments, you can reduce the interest owed and shorten your loan term.
The Mortgage Extra Payment Payoff Calculator makes this simple. It shows you exactly how much money you save on interest and how many years you can shave off your mortgage by making extra payments—whether small monthly additions or occasional lump sums.
What Is the Mortgage Extra Payment Payoff Calculator?
This calculator is a financial tool that helps homeowners understand the impact of paying more than the required minimum mortgage payment. It takes into account your loan amount, interest rate, loan term, and extra payments, then calculates:
How much total interest you will save
How many months (or years) earlier you can pay off your loan
It’s the easiest way to see the benefits of taking control of your mortgage payments.
