Break Even on Refinance Calculator

Determining when you'll break even on a refinance is crucial for making an informed financial decision. Our break even on refinance calculator helps you understand the timeline and savings potential of refinancing your mortgage.

What is a break-even refinance?

A break-even refinance refers to the point in time when the savings from refinancing your mortgage equal the costs associated with the refinancing process. This includes closing costs, points, and any other fees. The break-even point is typically measured in months or years after refinancing.

Refinancing can offer lower interest rates, reduced monthly payments, or access to cash, but these benefits must outweigh the upfront costs to be financially beneficial. Understanding your break-even point helps you determine whether refinancing is worth the effort.

How to calculate break-even on a refinance

Calculating the break-even point for a refinance involves comparing the savings from the new mortgage terms with the costs of refinancing. Here's how to do it:

Calculate your current monthly mortgage payment.
Determine the new monthly payment after refinancing.
Calculate the monthly savings from refinancing.
Add up all refinancing costs (closing costs, points, etc.).
Divide the total refinancing costs by the monthly savings to find the break-even period in months.

Break-even period (months) = Total refinancing costs / Monthly savings from refinancing

For example, if your refinancing costs are $5,000 and you save $100 per month, your break-even point would be 50 months (about 4.2 years).

Factors affecting break-even

Several factors can influence when you break even on a refinance:

Interest rate difference: A lower interest rate will increase your monthly savings.
Loan term: Shorter loan terms generally result in higher monthly payments but lower total interest paid.
Closing costs: Higher closing costs will extend the break-even period.
Points: Paying points upfront can lower your interest rate but increases upfront costs.
Current mortgage balance: A higher balance may mean a longer break-even period.

Understanding these factors can help you make a more informed decision about whether to refinance.

Example calculation

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

Scenario

Current mortgage balance: $200,000
Current interest rate: 5%
Current loan term: 30 years
New interest rate: 4%
New loan term: 15 years
Closing costs: $3,000
Points: 1% of loan amount ($2,000)

Step 1: Calculate current monthly payment

Using the standard mortgage payment formula:

M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1 ]

Where:

M = monthly payment
P = principal loan amount ($200,000)
i = monthly interest rate (5%/12 = 0.004167)
n = number of payments (30 years × 12 = 360)

Current monthly payment = $1,203.33

Step 2: Calculate new monthly payment

Using the same formula with the new terms:

M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1 ]

Where:

M = monthly payment
P = principal loan amount ($200,000)
i = monthly interest rate (4%/12 = 0.003333)
n = number of payments (15 years × 12 = 180)

New monthly payment = $1,622.83

Step 3: Calculate monthly savings

Monthly savings = New monthly payment - Current monthly payment

Monthly savings = $1,622.83 - $1,203.33 = $419.50

Step 4: Calculate total refinancing costs

Total refinancing costs = Closing costs + Points

Total refinancing costs = $3,000 + $2,000 = $5,000

Step 5: Calculate break-even period

Break-even period (months) = Total refinancing costs / Monthly savings

Break-even period = $5,000 / $419.50 ≈ 11.9 months

This means you'll break even on the refinance after approximately 12 months.

FAQ

What is the typical break-even period for refinancing?: The break-even period can vary widely depending on interest rates, closing costs, and other factors. It can range from a few months to several years.
Is it always better to refinance if the break-even period is long?: Not necessarily. A long break-even period may mean you'll pay more in total interest over the life of the loan. Consider other factors like cash-out potential or improved loan terms.
How can I lower my break-even period?: Lower your refinancing costs, negotiate better terms, or choose a loan term that maximizes your savings.
Should I refinance if I plan to sell soon?: If you plan to sell within the break-even period, refinancing may not be worth it unless you can use the cash-out for home improvements or other valuable purposes.
