Refinance Break Even Calculation Mortgage

Refinancing your mortgage can save you money, but it's important to know when it's truly worth it. Our refinance break even calculator helps you determine the optimal time to refinance by comparing the costs and savings of your current mortgage with a potential new loan.

What is Refinance Break Even?

The refinance break even point is the number of months or years after refinancing when the cumulative savings from the new loan equal the costs of refinancing. It helps you determine whether refinancing is financially beneficial in the long run.

Key factors that affect your refinance break even include:

Current mortgage interest rate
New mortgage interest rate
Closing costs of refinancing
Loan term length
Current mortgage balance

Refinancing is typically worth considering when the new interest rate is significantly lower than your current rate, and when you can afford the closing costs.

How to Calculate Refinance Break Even

The break even calculation for refinancing involves comparing the interest savings from the new loan with the costs of refinancing. The formula is:

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

Where:

Closing Costs - The total fees and costs associated with refinancing
Monthly Interest Savings - The difference in monthly interest payments between your current and new loan

To calculate monthly interest savings:

Monthly Interest Savings = (Current Monthly Payment - New Monthly Payment) - (Current Interest Rate - New Interest Rate) × Principal

This calculation helps determine how long it will take for the savings from the new loan to cover the costs of refinancing.

Example Calculation

Let's look at an example to understand how the refinance break even calculation works.

Factor	Current Mortgage	New Mortgage
Interest Rate	5.5%	4.5%
Loan Term	30 years	30 years
Loan Amount	$250,000	$250,000
Monthly Payment	$1,500	$1,350
Closing Costs	$0	$3,500

In this example:

Calculate monthly interest savings: $1,500 - $1,350 = $150 per month
Calculate break even months: $3,500 / $150 = 23.33 months

This means it will take approximately 23 months for the savings from the new loan to cover the $3,500 in closing costs.

Factors to Consider

When determining whether to refinance, consider these additional factors:

Interest rate difference - A larger difference between your current and new rate will result in greater savings
Loan term - Shorter terms may have higher monthly payments but lower total interest
Closing costs - These can vary significantly between lenders
Credit score - A higher score may qualify you for better rates
Market conditions - Interest rates fluctuate with economic conditions

It's important to compare multiple lenders and loan options to find the best refinance deal for your situation.
