Refinance Break-Even Calculator
Use this refinance break-even calculator to estimate how long it may take for monthly mortgage payment savings to cover upfront, out-of-pocket refinance closing costs. Enter your current and new estimated monthly payments, only the closing costs you will pay upfront, 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. If closing costs are financed, include their effect in the new monthly payment and do not enter those financed costs again as upfront costs.
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 only the refinance closing costs you expect to pay upfront or out of pocket. If costs are financed, make sure the new payment reflects the larger loan balance and do not enter those costs again here.
- Enter how many years you plan to keep this loan or stay in the home.
- Review the break-even point, monthly P&I savings, and payment-based result after closing costs over your planned period.
If the break-even point is within your planned timeline, monthly payment savings may recover the upfront cash outlay before you move or change loans. If it falls beyond your planned timeline, you may not recover the upfront closing costs in time. Use the Mortgage Refinance Calculator to compare financed closing costs as part of the new balance, payment, and interest.
How it works
This calculator estimates the break-even point for a mortgage refinance using the monthly payment amounts and upfront, out-of-pocket closing costs you enter.
It is designed for a focused question: how many months of lower payments may it take to recover the upfront cash outlay, and does that break-even happen before your planned timeline?
Break-even formula
Break-even months = Upfront closing costs ÷ Monthly savings
Main inputs in the estimate
- Monthly savings
- Current monthly principal and interest payment minus the new estimated monthly payment, which must already reflect any closing costs financed in the new balance
- Upfront closing costs
- Only refinance fees paid upfront or out of pocket; financed costs must be reflected in the new monthly payment and must not be entered again here
- 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.
- Payment-based result after closing costs = monthly P&I savings × total planned months − upfront closing costs. This is not a full-loan savings estimate.
- If the new monthly payment is the same as or higher than the current payment, a payment-based break-even is not available.
- If no upfront closing costs are entered, the upfront-cash break-even is immediate. This does not mean financed costs are free or recovered immediately.
- For financed or rolled closing costs, use the Mortgage Refinance Calculator to model the larger balance, payment, interest, and full-term total.
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.
- The payment-based result after closing costs is estimated as monthly P&I savings multiplied by planned months minus upfront, out-of-pocket closing costs.
- The closing-cost input includes only costs paid upfront. Costs financed or rolled into the new loan must be reflected in the new monthly payment and must not be entered again as upfront closing costs.
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 - Upfront, out-of-pocket 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 payment-based result after closing costs is about $15,000. This reflects cumulative P&I payment reductions minus the upfront costs; it is not a full-loan savings estimate.
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.

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 upfront, out-of-pocket refinance closing costs. Until that point, you are still recovering the upfront cash outlay. After that point, you begin to come out ahead on a cash-flow basis.
What closing costs should I include?
Include only the closing costs you will pay upfront or out of pocket, such as applicable origination, appraisal, title, and underwriting fees. If costs are financed or rolled into the new loan, reflect them in the new monthly payment and do not enter them again in the closing-cost field. Use the Mortgage Refinance Calculator for a full rolled-cost comparison.
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 upfront closing costs through payment savings before you sell or change loans. Reaching break-even still does not prove the refinance lowers total loan cost.
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 upfront 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 upfront closing costs you will pay.
