About This Refinance Calculator

The Refinance Calculator is a vital financial tool for anyone considering replacing their current mortgage or loan with a new one. Deciding to refinance involves more than just looking for a lower interest rate; you must account for closing costs, points, and the extension of your loan term to know if it truly saves you money.

What Is a Refinance Calculator?

This calculator allows you to compare your existing loan against a proposed new loan. By inputting your current remaining balance, your current monthly payment, and your interest rate, the calculator figures out exactly how much time and interest you have left. It then compares this to the new loan parameters to determine your true lifetime savings.

How the Refinance Formula Works

Our tool uses standard amortization equations to backwards-calculate your remaining term, and forward-calculate your new payments:

M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1 ]

Where M is the total monthly payment, P is the principal loan amount, i is the monthly interest rate, and n is the total number of payments (months). The break-even point is calculated by dividing your total upfront closing costs by your monthly savings.
