How to Calculate The Break-Even Point for A Mortgage Refinance

Refinancing your mortgage can save you money, but it's important to understand when the savings will outweigh the costs. The break-even point is the point at which the savings from refinancing equal the costs of refinancing. This guide will explain how to calculate the break-even point for a mortgage refinance and what it means for your financial situation.

What is the Break-Even Point?

The break-even point for a mortgage refinance is the time period after which the savings from refinancing exceed the costs of refinancing. It's calculated by comparing the interest savings from the new loan to the fees and closing costs associated with refinancing.

For example, if you refinance a $200,000 mortgage and save $500 per year in interest payments, but you incur $3,000 in closing costs, the break-even point would be 6 years. This means you would need to stay in the home for at least 6 years to see a net savings from refinancing.

How to Calculate the Break-Even Point

To calculate the break-even point for a mortgage refinance, you'll need to know the following:

The original mortgage balance
The new mortgage rate
The closing costs of refinancing
The term of the new mortgage

Break-Even Point Formula

Break-Even Point (in months) = (Closing Costs) / (Annual Interest Savings)

The formula works by dividing the total closing costs by the annual savings in interest payments. The result is the number of months it will take for the savings to equal the costs.

Important Note

The break-even point assumes you will stay in the home for the entire period. If you sell the home before the break-even point, you will not realize the savings from refinancing.

Worked Example

Let's walk through an example to illustrate how to calculate the break-even point.

Scenario

Original mortgage balance: $200,000
Original interest rate: 6%
New interest rate: 4%
Closing costs: $3,000
Loan term: 30 years

Step 1: Calculate Annual Interest Savings

First, calculate the annual interest payment for both the original and new loans.

Annual Interest Payment Formula

Annual Interest Payment = (Loan Balance × Interest Rate) / 12

Original annual interest payment:

($200,000 × 6%) / 12 = $10,000

New annual interest payment:

($200,000 × 4%) / 12 = $6,666.67

Annual interest savings:

$10,000 - $6,666.67 = $3,333.33

Step 2: Calculate Break-Even Point

Now, divide the closing costs by the annual interest savings to find the break-even point in months.

Break-Even Point (in months) = $3,000 / $3,333.33 = 0.9 months

Convert months to years:

0.9 months ÷ 12 = 0.075 years (approximately 9 months)

Interpretation

In this example, the break-even point is 9 months. This means you would need to stay in the home for at least 9 months to see a net savings from refinancing. If you sell the home before 9 months, you will not realize the savings from refinancing.

Key Factors to Consider

When calculating the break-even point for a mortgage refinance, there are several key factors to consider:

1. Closing Costs

Closing costs can vary widely depending on the type of loan and the lender. Some common closing costs include:

Appraisal fee
Credit report fee
Title insurance
Origination fee
Prepaid interest

2. Interest Rate Savings

The amount you save on interest payments depends on the difference between your original interest rate and the new interest rate. The larger the difference, the sooner you will reach the break-even point.

3. Loan Term

The term of the new mortgage can affect the break-even point. A shorter term may result in higher monthly payments but lower total interest over the life of the loan.

4. Property Value

The value of your property can impact the break-even point. If the property value increases, you may be able to refinance for a lower rate, which can reduce the break-even point.

FAQ

What is the average break-even point for a mortgage refinance?

The average break-even point for a mortgage refinance is between 3 and 5 years. However, this can vary widely depending on the specific circumstances of each refinance.

Can I refinance if the break-even point is longer than the remaining term of my mortgage?

No, if the break-even point is longer than the remaining term of your mortgage, refinancing may not be a good financial decision. In this case, it's better to wait until interest rates are lower before refinancing.

How do I know if refinancing is worth it?

Refinancing is worth it if the break-even point is shorter than the remaining term of your mortgage and if you can secure a lower interest rate. It's also worth considering other factors such as closing costs, loan terms, and property value.

What types of loans have the lowest closing costs?

Conventional loans and FHA loans typically have lower closing costs than jumbo loans or loans with special features such as cash-out refinancing. It's a good idea to shop around and compare closing costs from different lenders.
