Formula Used

The mortgage payoff savings is calculated using the following formula:

Savings = (Original Monthly Payment × Remaining Term) - (New Monthly Payment × New Term) - Early Payoff Amount

Where:

  • Original Monthly Payment = PMT(Original Balance, Original Interest Rate, Original Term)
  • New Monthly Payment = PMT(Original Balance - Early Payoff Amount, Original Interest Rate, New Term)
  • New Term = Original Term - (Early Payoff Amount / Original Monthly Payment)

This formula accounts for the reduced interest payments you'll make by paying off your mortgage early.

Worked Example

Let's say you have a $200,000 mortgage with a 4.5% interest rate and 30 years remaining. You want to pay off $50,000 early.

Using the calculator:

  1. Original monthly payment: $1,143.46
  2. New monthly payment: $1,025.62
  3. New term: 25.5 years (307 months)
  4. Total interest saved: $12,850.40

By paying off $50,000 early, you'll save $12,850.40 in interest payments and reduce your loan term by 4.5 years.

Frequently Asked Questions

How does paying off my mortgage early save me money?

Paying off your mortgage early reduces the principal balance faster, which means you'll pay less interest over the life of the loan. The calculator shows exactly how much you'll save by making an early payment.

Is there a penalty for paying off my mortgage early?

Some mortgage lenders charge prepayment penalties, but many conventional loans do not. Check your loan agreement or use our mortgage prepayment penalty calculator to determine if you'll be charged.

How does early mortgage payoff affect my credit score?

Paying off your mortgage early can improve your credit utilization ratio and show lenders you're managing debt responsibly. However, it won't directly affect your credit score unless you close the account.
