Introduction

A refinance calculator helps homeowners determine if refinancing their mortgage is financially beneficial. By comparing your current loan terms with potential new terms, you can calculate monthly savings, total interest savings, and determine how long it will take to recoup closing costs.

Refinancing can be a smart financial move when interest rates drop or your credit situation improves. This calculator helps you make an informed decision by showing the break-even point and total savings over the life of the loan, accounting for closing costs and fees.

How to Use

  1. Enter Current Loan Details: Input your current loan amount, interest rate, and remaining term. You can find this information on your mortgage statement or by contacting your lender.
  2. Enter New Loan Terms: Input the interest rate and term you're considering for refinancing. Shop around with multiple lenders to find the best rates and terms available.
  3. Add Closing Costs: Include all closing costs like appraisal fees, attorney fees, and loan origination fees. These typically range from 2% to 5% of the loan amount.
  4. Calculate Results: Click "Calculate Refinance Savings" to see your potential savings, break-even point, and monthly payment differences.

Formulas

Monthly Payment Formula:

M = P × [r(1+r)^n] / [(1+r)^n - 1]

Where:

  • M: Monthly payment
  • P: Principal loan amount
  • r: Monthly interest rate
  • n: Number of payments

Break-Even Formula:

Break-Even Months = Closing Costs ÷ Monthly Savings

Shows how long to recoup refinancing costs

Frequently Asked Questions

When should I refinance my mortgage?

Consider refinancing when you can get an interest rate at least 1% lower than your current rate, your credit score has improved, or you want to change your loan term. Also consider if you plan to stay in your home long enough to recoup closing costs.

What are typical closing costs?

Closing costs typically range from 2% to 5% of the loan amount and include appraisal fees, attorney fees, title insurance, loan origination fees, and recording fees. Always get a detailed breakdown from your lender.

Is it worth refinancing for a small rate reduction?

Even small rate reductions can be worthwhile if you plan to stay in your home long enough. Use the break-even calculation to determine if the monthly savings justify the closing costs over your expected time in the home.
