What Is a Mortgage Payoff Calculator?
A mortgage payoff calculator is a financial tool that demonstrates the power of making extra payments on your mortgage. It compares your original loan schedule with a new schedule based on your chosen payoff strategy (like adding extra to your monthly payment), showing you the potential savings in both time and money.
How to Use This Calculator
- Enter your current mortgage loan balance.
- Input your loan's annual interest rate.
- Enter your current monthly payment (principal and interest only).
- Choose an extra payment strategy (e.g., extra monthly, extra yearly).
- Enter the extra amount you wish to pay.
- Click "Calculate" to see your new payoff date and total interest saved.
Understanding Your Mortgage Payoff Results
- Interest Saved: The most important number. This is the total amount of interest you will avoid paying over the life of the loan by making extra payments.
- New Payoff Date: Shows you the new month and year your mortgage will be completely paid off.
- Time Saved: Displays exactly how many years and months you'll shave off your loan term.
