This is an estimate only. Check with your lender for exact payoff schedule and policy on extra payments.
What is this?
Mortgage payoff calculation helps you understand how extra payments can significantly reduce your loan term and save thousands in interest. By paying more than your required monthly payment, you directly reduce the principal balance, which decreases future interest calculations.
How to Use the Mortgage Payoff Calculator
For most people, a mortgage is the biggest financial obligation that they will ever make, and a little tuck in payment strategy may generate savings in interest of tens of thousands. An extra payment, whether it be monthly, yearly, biweekly, or one-time, directly reduces your loan principal and shortens your payoff timeline.
The Mortgage Payoff Calculator will help you understand precisely how additional payments affect your mortgage term, total interest paid, and payoff date. It compares your current repayment schedule with accelerated payoff scenarios, giving you a clear picture of possible savings.
Instead of just guessing whether extra payments are worth it, this calculator gives you precise results through the use of amortization logic. You can explore different strategies without affecting your required monthly payment, helping you make confident, informed decisions when it comes to your home loan.
1. Enter Original Loan Details
Enter your original loan amount and original loan term. These values reflect the mortgage as issued by your lending institution.
This will be used by the calculator to rebuild your regular amortization schedule.
2. Provide Interest Rate and Remaining Term
Enter your mortgage interest rate and loan term left, which tells our calculator how much principal is left on your mortgage.
Realistic estimates for payoffs and interest savings are ensured if and only if remaining term inputs are correct.
3. Choose a Repayment Strategy
Select how you want to accelerate repayment:
• Normal payment - no extra payments
• Extra monthlies
• Additional annual lump-sum payments
• Lump sum payments
• Biweekly payment
• Payoff in its entirety
Each of these options affects the interest savings and payoff time differently.
4. Enter Extra Payment Amounts
If extra payments are to be applied, include how much per month, per year you will contribute, or as one big, lump sum payment.
All additional payments go directly to the principal, therefore decreasing all future interest charges.
5. Calculate and Compare Results
After calculating, review your reduced payoff time, total interest saved, and updated amortization schedule.
This comparison will help you balance the affordability-savings equation and determine which strategy offers the best balance.
Key Formulas Used in the Calculator
Monthly Mortgage Payment (PMT)
This standard amortization formula calculates your required monthly mortgage payment based on loan amount, interest rate, and term.
Interest Per Period
Interest is calculated on the remaining principal each period. Extra payments reduce this balance and lower future interest.
New Remaining Balance
Extra payments increase principal reduction, accelerating payoff and shrinking total interest paid.
