Mortgage Renewal Calculator – Help Guide

The Mortgage Renewal Calculator helps you compare your current mortgage terms against new renewal options. When your mortgage term ends, you can renew at the best available rate. This tool quantifies potential savings from switching lenders or negotiating a better rate.

How to Use This Tool

  1. 1

    Enter your current mortgage balance

    Enter the remaining principal balance on your current mortgage.

  2. 2

    Enter your current rate and payment

    Input the interest rate and monthly payment you are currently paying.

  3. 3

    Enter the new renewal rate

    Enter the rate being offered at renewal (from your current lender or a competitor).

  4. 4

    Enter remaining amortization

    Enter how many years remain on your original amortization schedule.

  5. 5

    Compare the results

    Review the difference in monthly payments and total interest paid over the term.

Helpful Tips

  • Start shopping 120 days before your renewal date. Most lenders allow you to lock in a rate that far in advance.
  • Don't just accept the first renewal offer from your current lender. Competitors often offer lower rates.
  • If breaking your mortgage early, calculate the prepayment penalty (typically 3 months interest or IRD, whichever is greater).
  • A lower rate is not always better if it comes with high fees or restrictive prepayment privileges.
