Refinance Break-Even Calculator
A refinance only saves money once your lower payments have repaid the closing costs. This finds that break-even month — and whether you'll stay in the home long enough to reach it.

Break-even = closing costs ÷ monthly savings. If you plan to sell or refinance again before this point, the refinance loses money. Watch the term: resetting to a new 30 years lowers the payment but can raise lifetime interest.
What "break-even" really means
Refinancing replaces your current mortgage with a new one, ideally at a lower rate. But it isn't free — closing costs typically run a few thousand dollars. The refinance only starts saving you money once your reduced monthly payments have added up to more than those upfront costs. That tipping point is the break-even month.
If your closing costs are $8,000 and you save $320 a month, you break even in 25 months — just over two years. Stay in the home past that, and every month afterward is pure savings. Leave before it, and the refinance cost you money.
The trap most refinance ads hide
A lower monthly payment isn't automatically a better deal. If you've been paying a 30-year loan for a few years and refinance into a fresh 30-year term, you reset the clock. The monthly payment drops partly because of the lower rate and partly because you've stretched the remaining balance back out over 30 years. That can mean paying more total interest over the life of the loan even while your monthly payment falls.
To avoid this, compare not just payments but the term. Refinancing a loan with 28 years left into a new 15- or 20-year term often saves dramatically more interest, even if the monthly payment doesn't fall as much. Match the new term to how long you realistically expect to keep the loan.
When refinancing makes sense
- The rate drop is meaningful and you'll stay past the break-even point.
- You can refinance into a shorter term without straining your budget.
- You're switching out of an adjustable-rate mortgage (ARM) or FHA (Federal Housing Administration) loan into a fixed conventional loan.
It makes less sense if you'll move soon, if closing costs are high relative to the savings, or if you're deep into a low-rate loan you'd be giving up.
Frequently asked questions
Should I roll closing costs into the loan?
You can, which avoids paying cash upfront, but it increases your balance and slightly raises your payment and total interest. The break-even logic still applies; just use your real net savings.
Is a "no-closing-cost" refinance really free?
No. The lender covers the costs in exchange for a higher rate or a larger balance. It can still make sense if you'll move before a points-based refinance would break even.
How big a rate drop do I need?
There's no fixed rule — it depends on your balance and closing costs. The break-even month is the honest test: if it's comfortably shorter than how long you'll keep the loan, the refinance is worth considering.
How many times can you refinance your mortgage?
There's no legal limit on how many times you can refinance, though some lenders enforce a minimum seasoning period — often six months — between refinances. Each refinance resets the break-even clock, so run the numbers again every time.
Does refinancing hurt your credit score?
Applying triggers a hard inquiry, which can dip your score a few points temporarily, and opening a new account lowers your average account age. Most people see scores recover within a few months of consistent on-time payments.
How soon can I refinance after buying a home?
Conventional loans often allow refinancing at any time, though many lenders and some loan programs impose a seasoning period of six months or more. Cash-out refinances and government-backed loans like FHA (Federal Housing Administration) and VA (Department of Veterans Affairs) commonly have longer waiting periods — check your specific program.
Is it worth refinancing for a 0.5% rate drop?
It can be, especially on a large balance held for many years, but run the break-even math first — a small rate drop produces small monthly savings, so it may take longer to recoup closing costs. This calculator will show you the exact break-even month for your numbers.
Do I need a new appraisal to refinance?
Usually yes, for a conventional rate-and-term or cash-out refinance, though some streamline refinance programs (like FHA or VA streamline) can skip the appraisal. Ask your lender whether your specific refinance qualifies for an appraisal waiver.
