What is it?
This calculator finds the break-even point for a mortgage refinance — how many months it takes for the monthly savings from a lower rate to cover the closing costs of refinancing — so you can decide whether refinancing makes financial sense given how long you plan to stay in the home.
Formula
Monthly Savings = Current Payment − New Payment
Break-Even Months = Closing Costs ÷ Monthly Savings
Formula Explanation
Refinancing replaces your current loan with a new one, usually at a lower rate, but it isn't free — closing costs (appraisal, origination fees, title insurance, etc.) are paid upfront. The break-even point is when your accumulated monthly savings equal those upfront costs — refinancing only becomes a net financial win after that point.
Example Calculation
Refinancing a $300,000 balance from 7.5% to 6.5% (same 25-year remaining term) lowers the payment by about $191/month. With $5,000 in closing costs, the break-even point is about 26 months — if you plan to stay longer than that, refinancing likely pays off.
How to Use
- Enter your current loan's remaining balance, rate, and remaining term.
- Enter the new loan's rate, term, and closing costs from the refinance offer.
- Enter how many years you plan to stay in the home.
- Check whether the break-even point falls before or after your planned time in the home.
Benefits
- Gives a clear, concrete break-even timeline instead of just comparing interest rates.
- Shows both monthly savings and total lifetime interest savings from refinancing.
- Directly answers whether refinancing is worth it based on how long you actually plan to stay.
Use Cases
- Deciding whether to accept a refinance offer from your lender.
- Comparing multiple refinance offers with different rates and closing costs.
- Checking whether refinancing still makes sense if you might sell or move within a few years.
What Your Result Means
If the break-even point is well within your planned time in the home, refinancing is likely a good financial move. If it's close to or beyond how long you plan to stay, the closing costs may not be worth paying — you'd move or sell before recouping them.
Tips
- Watch out for refinance offers that reset your loan term back to 30 years — this can lower monthly payments while increasing total lifetime interest, even at a lower rate.
- Factor in how likely you are to move earlier than planned — job changes and life events can shorten your actual time in the home.
- Compare the total interest over the life of both loans, not just the monthly payment, for the full picture.
Common Mistakes
- Ignoring closing costs entirely and only comparing the interest rate difference.
- Resetting the loan term to a fresh 30 years without realizing it increases total interest paid, even at a lower rate.
- Refinancing without considering how many more years you actually plan to stay in the home.
FAQs
Is refinancing always a good idea if the rate is lower?
Not necessarily — closing costs need time to be recouped through monthly savings, so refinancing is most beneficial if you plan to stay in the home well beyond the break-even point.
Should I reset my loan term when refinancing?
Resetting to a fresh full term (like 30 years) usually lowers your monthly payment further but can increase total interest paid over the life of the loan — consider matching your new term to your remaining term instead if minimizing total interest matters more.
What closing costs should I expect when refinancing?
Refinance closing costs typically run 2-5% of the loan amount, covering appraisal, origination, title, and other fees — get a detailed quote from your lender for exact figures.
This tool estimates break-even based on principal and interest payments only — actual refinance offers may include additional fees or terms not captured here.
