Refinance Break-Even Calculator
Enter your refinance closing costs and your current and new monthly payments to see your refinance break-even point — the month your monthly savings finally recover what you paid in fees.

It is not financial, lending, tax or legal advice, and it does not guarantee any loan terms, rate, payment or approval. Actual figures depend on your lender, credit, location and the final terms of any loan.

How the break-even calculator works
Refinancing is not free. You pay closing costs up front, and in exchange you get a lower monthly payment. The break-even point is the moment those two things cancel out — the month your accumulated monthly savings finally overtake everything you spent on closing costs. Before that month you are still in the hole; after it, every dollar you save is pure gain.
The math is refreshingly simple. Take what you spent to get the new loan and divide it by how much you save each month:
Break-even months = Closing costs ÷ Monthly savings
Your monthly savings is just your old principal-and-interest payment minus your new one. If the new payment is not lower than the old one, there is no monthly saving to divide by, and there is nothing to break even on — a refinance only "pays for itself" when it actually lowers the payment.
A worked example
Suppose your current payment is $2,179 a month and you can refinance into a new loan with a payment of $1,918, paying $4,500 in closing costs:
- Your monthly saving is $2,179 − $1,918 = $261.
- Break-even is $4,500 ÷ $261 ≈ 17 months.
- After 17 months your savings have repaid the costs; from month 18 on you are ahead.
- Over three years that same $261/month adds up to about $4,896 in net savings after costs.
Where do you get those two payment figures? The quickest way is to run your numbers through our refinance calculator — it shows both your current payment and the new payment side by side, and you can drop them straight into this tool.
What affects your break-even point
- The size of the rate drop. A bigger gap between your old and new rate means a bigger monthly saving, which shrinks the number of months to break even.
- Your closing costs. Higher fees and points mean more to recover, so break-even moves further out. Shop lenders and ask for a full fee breakdown.
- Whether you roll costs into the loan. Financing the fees raises your new payment slightly, which trims the monthly saving and lengthens break-even compared with paying cash up front.
- How long you will stay. Break-even only matters relative to your timeline. The longer you keep the loan past break-even, the more the refinance pays off.
Mind your timeline. If you expect to sell or move before you hit break-even, a refinance can lose money even at a lower rate — you pay the costs but leave before the savings catch up. Also note this simple version only compares monthly payments; it ignores differences in loan term and lifetime interest, so a shorter-term refinance can look bad here while still being a great deal.

Frequently asked questions
What is a good break-even point for a refinance?
There is no single magic number, but most homeowners want to break even well before they plan to sell or move. A break-even under about two years is generally excellent, two to four years is reasonable, and beyond five years you should think hard about whether you will keep the loan long enough to come out ahead.
What counts as closing costs?
Closing costs are the fees you pay to get the new loan: lender origination and underwriting fees, an appraisal, title insurance and search, recording fees, and any discount points you buy. They typically run 2–5% of the loan amount. Use our closing cost calculator at /closing-cost-calculator/ to estimate yours before you plug a number in here.
Does rolling closing costs into the loan change the break-even?
A little. If you roll the costs into the new balance instead of paying cash, you finance those fees and your new payment is slightly higher, which shrinks the monthly saving and pushes break-even out. The closing-cost dollar figure you divide by stays the same, but the saving in the denominator gets smaller, so the payback takes a bit longer.
What if I refinance to a shorter term?
A shorter term (say 30 years down to 15) often raises your monthly payment, so this simple break-even math may show no monthly saving even though the refinance saves you a fortune in lifetime interest. When you shorten the term, break-even on payment is the wrong lens — use the full /refinance-calculator/ to compare lifetime interest instead.
Does this calculator account for taxes and insurance?
No. Enter principal-and-interest payments only. Property taxes and homeowners insurance are usually the same before and after a refinance, so leaving them out keeps the comparison clean. The exception is mortgage insurance — if a refinance lets you drop PMI, your real saving is larger than this tool shows.
Is the break-even point exact?
It is a close estimate. The calculation divides your closing costs by your monthly saving, which ignores small differences in how each loan amortizes and any interest you could earn on the cash you keep. It is accurate enough to decide whether a refinance is worth it, but always confirm the fees and payments with your lender.
