Refinance Break-Even Calculator
Use this refinance break-even calculator to estimate how long it may take for monthly mortgage payment savings to cover refinance closing costs. Enter your current and new estimated monthly payments, refinance closing costs, and how long you plan to keep the loan or stay in the home.
This is a focused break-even tool. It is not a full refinance comparison calculator. If you want to compare current and new loan scenarios side by side, including rate, balance, and term, use the Mortgage Refinance Calculator.
Results are planning estimates only and do not include taxes, fees, inflation, or changing market returns.
How to use this calculator
- Enter your current monthly principal and interest payment. Use the P&I portion only, not the full payment with taxes and insurance.
- Enter the estimated new monthly payment for the refinance scenario you are considering.
- Enter the total refinance closing costs you expect to pay.
- Enter how many years you plan to keep this loan or stay in the home.
- Review the break-even point, monthly savings, and net savings estimate over your planned period.
If the break-even point is within your planned timeline, the refinance may recover its cost before you move or change loans. If it falls beyond your planned timeline, you may not recover the closing costs in time.
How it works
This calculator estimates the break-even point for a mortgage refinance using only the monthly payment amounts and closing costs you enter.
It is designed for a focused question: how many months of lower payments may it take to recover the refinance closing costs, and does that break-even happen before your planned timeline?
Break-even formula
Break-even months = Refinance closing costs ÷ Monthly savings
Main inputs in the estimate
- Monthly savings
- Current monthly principal and interest payment minus the new estimated monthly payment
- Refinance closing costs
- All fees paid to complete the refinance, treated as paid upfront unless already reflected in the new monthly payment
- Planned period
- How long you expect to keep the loan or stay in the home, in years and months
What the estimate assumes
- Break-even is estimated from monthly payment savings only and does not account for interest saved over time, tax effects, escrow changes, or loan balance.
- Monthly savings are assumed to stay constant over the planned period.
- Net savings over the planned period = monthly savings × total planned months − closing costs.
- If the new monthly payment is the same as or higher than the current payment, a payment-based break-even is not available.
- If closing costs are zero, the break-even is immediate.
Assumptions and limitations
- Break-even is estimated from monthly payment savings only. It does not account for tax effects, escrow changes, or interest savings over time.
- Monthly savings are assumed to stay constant over the planned period. Real payments can change if taxes, insurance, or rates on adjustable-rate loans change.
- This calculator does not verify that a refinance is possible or estimate what rate or payment you may qualify for.
- Net savings over the planned period is estimated as monthly savings multiplied by planned months minus total closing costs.
- Closing costs are treated as paid upfront unless already reflected in the new monthly payment.
Example scenario
Use this example to see how a payment-based break-even estimate works.
- Current monthly principal and interest payment:
$2,200 - New estimated monthly payment:
$1,950 - Refinance closing costs:
$6,000 - Planned stay:
7 years
With those assumptions, the estimated monthly savings is $250.
The estimated break-even point is about 24 months (2 years).
Over the planned 7-year stay (84 months), the estimated net savings is about $15,000 after recovering the closing costs.
This example shows why a short planned stay changes the math. If you plan to sell or move in 2 years or less, you may not reach break-even before you go.
For help reading the output, see how to judge what is a good refinance break-even result. If you want the formula behind the estimate, use the guide on how to calculate the break-even number. You can also compare how refinance closing costs affect break-even or how your planned stay after refinancing changes the decision.
Frequently asked questions
What is a refinance break-even point?
The break-even point is when the cumulative monthly savings from a lower mortgage payment equal the total refinance closing costs. Until that point, you are still recovering the upfront cost of refinancing. After that point, you begin to come out ahead on a cash-flow basis.
What closing costs should I include?
Include all fees you will pay to complete the refinance, such as origination fees, appraisal, title, underwriting, and any prepaid items specific to your lender. If any costs are rolled into the new loan balance, your new monthly payment will reflect that and should be entered accordingly.
Is refinancing worth it if I plan to move soon?
That depends on whether you reach break-even before you move. If the break-even point is beyond your planned stay, you may not recover the closing costs through payment savings before you sell or change loans. This calculator is designed to help you see that tradeoff clearly.
What if my new payment is higher than my current payment?
If the new monthly payment is the same as or higher than the current payment, there are no monthly savings to recover closing costs. This calculator will indicate that a payment-based break-even is not available in that scenario.
Should I compare APR or interest rate?
For the payment-based break-even estimate this calculator uses, you only need the monthly payment amounts, not the rate directly. APR is useful when comparing lender offers because it folds in fees. Interest rate alone does not tell you the full cost. Neither is a substitute for seeing the actual monthly payment change and the total closing costs you will pay.
