Mortgage Refinance Break Even Calculator Excel

Deciding when to refinance your mortgage can be complex. Our mortgage refinance break even calculator helps you determine the optimal time to refinance by calculating the point at which the savings from the new loan outweigh the costs of refinancing.

Introduction

Refinancing your mortgage can save you money in the long run, but it's important to understand the break-even point—the time when the savings from the new loan equal the costs of refinancing. This calculator helps you determine that break-even point by considering factors like the current interest rate, new interest rate, closing costs, and loan term.

Whether you're considering a rate-and-term refinance or a cash-out refinance, understanding the break-even point helps you make an informed decision about when to refinance.

How to Use This Calculator

Enter your current mortgage balance.
Enter your current interest rate.
Enter the new interest rate you're considering.
Enter the estimated closing costs for refinancing.
Enter the loan term in years.
Click "Calculate" to see the break-even point.

The calculator will display the number of months it will take for the savings from the new loan to cover the costs of refinancing.

Formula Explained

The break-even point is calculated using the following formula:

Break Even Months = (Closing Costs) / (Monthly Savings)

Where Monthly Savings is calculated as:

Monthly Savings = (Current Monthly Payment - New Monthly Payment)

Current and new monthly payments are calculated using standard mortgage payment formulas.

Worked Example

Let's say you have a $200,000 mortgage with a 4.5% interest rate. You're considering refinancing to a 3.5% rate with $3,000 in closing costs over a 30-year term.

Using the calculator:

Current monthly payment: $1,073.64
New monthly payment: $928.16
Monthly savings: $145.48
Break-even months: 20.6 months (1 year and 8 months)

This means it will take about 1 year and 8 months for the savings from the new loan to cover the $3,000 in closing costs.

Frequently Asked Questions

What is the break-even point for refinancing?

The break-even point is the time when the savings from the new loan equal the costs of refinancing. This calculator helps you determine that point by calculating how long it will take for the monthly savings to cover the closing costs.

How do I know if refinancing is worth it?

Refinancing is worth it if the break-even point is within your expected timeframe for staying in the home. If the break-even point is longer than you plan to stay, refinancing may not be beneficial.

What factors affect the break-even point?

The break-even point is affected by the current interest rate, new interest rate, closing costs, loan term, and the length of time you plan to stay in the home.

Can I use this calculator in Excel?

Yes, the formulas used in this calculator can be easily implemented in Excel. The key formulas are the monthly payment calculation and the break-even point calculation.
