Refinance Break Even Calculator Excel

Determine the optimal time to refinance your mortgage by calculating the break-even point where the savings from a new loan outweigh the costs. This calculator helps you compare current and potential loan terms to make an informed financial decision.

What is Refinance Break Even?

The refinance break even point is the number of months or years after which refinancing becomes financially beneficial. It's calculated by comparing the total cost of your current mortgage with the total cost of a new loan, including closing costs and interest savings.

Key factors that affect your break even point include:

Current interest rate vs. new interest rate
Loan term length
Closing costs
Current loan balance
Property value appreciation

Important Consideration

Refinancing should not be done solely for tax benefits. While refinancing can reduce your taxable income, it's important to consider all financial implications before proceeding.

Key Formulas

Monthly Payment Formula

P = L × [r(1 + r)^n] / [(1 + r)^n - 1]

Where:

P = Monthly payment
L = Loan amount
r = Monthly interest rate (annual rate / 12)
n = Number of payments (loan term in years × 12)

Break Even Point Formula

Break Even Months = Closing Costs / (Current Monthly Payment - New Monthly Payment)

Where:

Closing Costs = Total fees for the new loan
Current Monthly Payment = Payment on your existing loan
New Monthly Payment = Payment on the proposed new loan

Example Calculation

Let's look at an example to illustrate how the break even point is calculated.

Current Loan	New Loan
Balance: $200,000	Balance: $200,000
Interest Rate: 4.5%	Interest Rate: 3.5%
Term: 30 years	Term: 30 years
Monthly Payment: $972.64	Monthly Payment: $870.64
Closing Costs: N/A	Closing Costs: $3,000

In this example, the break even point would be calculated as:

Break Even Months = $3,000 / ($972.64 - $870.64) = $3,000 / $102 = 29.4 months

This means you would need to stay in your current loan for about 29 months before refinancing becomes financially beneficial.

When to Refinance

Refinancing is typically recommended when:

Your current interest rate is significantly higher than available rates
You have good credit and can qualify for a lower rate
You plan to stay in your home for at least 5-7 years
You can afford the closing costs
You expect your home value to appreciate

It's important to consider all factors before refinancing, including potential tax implications and the impact on your overall financial situation.
