Mortgage Refinance Break-Even Calculator
What is a Mortgage Refinance Break-Even Point?
The mortgage refinance break-even point is the moment when the monthly savings generated by a lower interest rate finally cover the upfront costs of the refinancing process. Refinancing isn't free; homeowners typically pay between 2% and 5% of the loan amount in closing costs, including appraisal fees, title insurance, and origination charges.
How to Calculate Your Refinance Savings
To find your break-even point, you must use a specific formula. Our calculator automates this math, but here is the logic behind it:
- Calculate Monthly Savings: Subtract your new principal and interest payment from your current payment.
- Total the Costs: Sum up all closing costs, including "points" paid to lower the rate.
- Divide: Divide the total costs by the monthly savings. The result is the number of months required to "break even."
Realistic Example:
Imagine you have a monthly payment of $2,000. You refinance to a new rate that drops your payment to $1,750, saving you $250 per month. If the closing costs for this new loan are $6,000, your calculation would be:
$6,000 (Costs) รท $250 (Savings) = 24 Months
In this scenario, you must stay in the home for at least two years to justify the cost of the refinance.
Factors That Influence the Decision
- Duration of Homeownership: If you plan to sell the house in 12 months but your break-even point is 36 months, you will lose money by refinancing.
- Loan Term: If you move from a 30-year mortgage to a 15-year mortgage, your monthly payment might actually increase, but you will save tens of thousands in interest over the life of the loan.
- Taxes and Insurance: Remember that our calculator focuses on Principal and Interest. Property taxes and homeowners insurance typically stay the same regardless of your refinance.
When is Refinancing a Bad Idea?
Refinancing may not be the best move if your credit score has dropped since your original loan, as you might not qualify for the best rates. Additionally, if you are very far along in your current mortgage (e.g., year 20 of a 30-year loan), restarting the clock with a new 30-year loan could significantly increase the total amount of interest you pay over time, even if the monthly payment is lower.
