The break-even formula is straightforward: divide your total closing costs by your monthly savings to find the number of months it takes to recoup the cost of refinancing. If you sell or move before reaching that point, you lose money on the deal. This calculator computes your exact break-even month and shows whether refinancing is worth it based on how long you plan to stay. Keep in mind that while refinancing to a lower rate usually reduces your monthly payment, choosing a longer new term can increase your total interest paid over the life of the loan. All rate and cost figures used here are estimates.
Compare your current mortgage with a refinanced loan to see if refinancing saves you money and when you break even on closing costs.

The core formula behind every refinance break-even calculator is: closing costs divided by monthly savings equals break-even months. If your refinancing fees total $6,000 and you save $185 per month, the break-even point is roughly 32 months. Every month after that, the savings are pure gain.
This number matters because selling or relocating before you reach break-even means the refinance cost you money rather than saving it. Lenders do not refund closing costs if you move early. The break-even calculation gives you a clear threshold: stay past it and you win, leave before it and you lose.
Worked Example: $300,000 Balance at 7% Refinanced to 6%
Current payment (30-year at 7%): roughly $1,996/month. New payment (30-year at 6%): roughly $1,799/month. Monthly savings: approximately $197. With $6,000 in closing costs, break-even is about 30 months ($6,000 / $197 = 30.5). If you plan to stay in the home for more than two and a half years, the refinance puts you ahead. These are estimates and actual figures depend on your specific loan terms.
Your monthly savings come from the difference between your current mortgage payment and the new payment after refinancing. The new payment depends on the new interest rate and the new loan term. A larger rate drop produces larger savings, but shortening the term can reduce or even eliminate the monthly savings despite a lower rate.
The table below shows how different rate drops affect savings on a $300,000 balance with a 30-year term and $6,000 in closing costs:
Rate Drop Comparison: $300,000 Balance, 30-Year Term, $6,000 Closing Costs
7% to 6.5%: Payment drops from ~$1,996 to ~$1,896. Monthly savings: ~$100. Break-even: ~60 months. 7% to 6%: Payment drops from ~$1,996 to ~$1,799. Monthly savings: ~$197. Break-even: ~30 months. 7% to 5.5%: Payment drops from ~$1,996 to ~$1,703. Monthly savings: ~$293. Break-even: ~20 months. A full 1.5 percentage point drop cuts the break-even period to under two years, making refinancing worthwhile even for homeowners who might move in the near future. All figures are estimates as of July 2026.
The decision comes down to comparing your break-even months against your planned stay in the home. If you intend to stay for ten or more years, even a modest rate drop of 0.25% can be worth it because you have decades to recoup the costs and accumulate savings. The longer you stay past break-even, the more you benefit.
If you plan to move within two to three years, you need substantial monthly savings to justify the closing costs. A break-even of 24 months or less is generally considered a safe threshold for a short timeline. Anything beyond 36 months becomes risky if your plans are uncertain.
One common pitfall is the term-reset warning. If you are ten years into a 30-year mortgage and refinance into a new 30-year loan, your monthly payment drops but you have added ten more years of interest payments. Extending from 20 remaining years back to 30 can increase total interest despite the lower rate. The calculator flags this when it detects a term extension, so you can decide whether the lower monthly payment justifies the higher lifetime cost.
Closing costs are the single largest factor in determining your break-even point. They typically include an appraisal fee ($300 to $500), title and escrow services ($1,500 to $3,000), loan origination (0.5% to 1% of the loan amount), and recording fees ($50 to $500). Together, these costs usually total 2% to 6% of the loan balance, or $6,000 to $18,000 on a $300,000 mortgage.
You can minimize these costs by shopping multiple lenders, negotiating fees, and asking about lender credits. Lender credits reduce or eliminate your upfront costs in exchange for a slightly higher interest rate, which can make sense if you plan to move before the higher rate erodes your savings.
Rolling closing costs into the new loan means you pay no money at closing, but it increases your loan balance. A higher balance means a higher monthly payment, which reduces your monthly savings and pushes the break-even point further out. Paying costs upfront shortens break-even, while financing them extends it. The calculator lets you compare both approaches.
Typical Closing Cost Breakdown on a $300,000 Refinance
Appraisal fee: $300 to $500. Title and escrow: $1,500 to $3,000. Origination fee (0.5%-1%): $1,500 to $3,000. Recording fee: $50 to $500. Other costs (credit report, underwriting, survey): $500 to $2,000. Total typical range: $3,850 to $9,000, with higher-cost markets reaching 4-6% of the loan. These are estimates as of July 2026 and vary by lender and location.
A cash-out refinance lets you borrow against your home equity by taking a new loan that is larger than your current balance. The difference is paid to you in cash. For example, if you owe $200,000 on a home worth $400,000, you might refinance into a $280,000 loan and receive $80,000 in cash after closing costs.
This larger loan balance affects the break-even calculation in two ways. First, closing costs are higher because they are based on a bigger loan amount. Second, your new monthly payment may be closer to (or even higher than) your old payment, depending on how much cash you take out and what the new rate is. When monthly savings are small or negative, the break-even point extends dramatically or never arrives.
Cash-out refinancing can make sense when the proceeds fund home improvements that increase property value or when they consolidate higher-interest debt into a lower mortgage rate. It is generally not advisable to use home equity for consumption, such as vacations or luxury purchases, because you are converting unsecured spending into debt secured by your home. The calculator helps you see the real cost by showing how the cash-out amount shifts your break-even month and total interest.
