hat is a Refinance Mortgage Payment Calculator?
A Refinance Mortgage Payment Calculator is an online financial tool that allows borrowers to estimate their new loan payments when considering refinancing their existing mortgage.
It calculates:
- Monthly Payment – the estimated amount you’ll pay each month.

- Total Interest – how much interest you’ll pay, separate from the principal.
By entering just a few numbers, you can compare different refinancing scenarios and make smarter financial decisions.
Why Use a Refinance Calculator?
Refinancing can be beneficial, but it comes with costs like fees, closing costs, and long-term interest implications. Using this calculator gives you:
✅ A clear picture of monthly affordability
✅ Insight into total interest costs over time
✅ The ability to compare loan terms (e.g., 15-year vs. 30-year)
✅ Quick decision-making without manual calculations

Using the calculator is simple and takes less than a minute:
- Enter Loan Amount – The amount you plan to refinance (e.g., $200,000).
- Enter Interest Rate – Your new estimated annual interest rate (e.g., 5%).
