What is the refinance break-even point?

The break-even point is the time it takes for monthly savings to cover closing costs. A common estimate is break-even months = closing costs ÷ monthly savings.

Should I include closing costs in the loan or pay them upfront?

Paying upfront increases cash needed today, while rolling costs into the loan increases the balance and interest paid. Compare both scenarios using the same rate and term.

When does refinancing usually help?

Refinancing can help when the new rate meaningfully lowers your payment or total interest and you plan to keep the loan long enough to pass the break-even point.

When might refinancing not help?

It may not help if closing costs are high, your rate reduction is small, you plan to move soon, or you reset to a longer term that increases total interest.

How does the remaining loan term matter?

If you have many years left, a lower rate can save more interest over time. If you have few years left, closing costs can be harder to recoup unless savings are large.

Does a lower monthly payment always mean I save money?

Not always. Extending the term can lower the payment but increase total interest. Compare both monthly payment and total cost across the scenarios.

How This Calculator Works

This refinance calculator compares your current mortgage to a new loan scenario to estimate payment changes and break-even time.

Enter current loan details: Remaining balance, current rate, remaining term, and your current monthly payment (if requested).
Enter the refinance offer: New rate and term, plus any upfront costs (points, lender fees, title, etc.).
Calculate monthly savings: Estimate how much the new payment changes compared to the current payment.
Estimate break-even: Closing costs divided by monthly savings gives a quick “months to break even” estimate.
Interpret the result: If you plan to keep the loan beyond break-even, refinancing is more likely to help.

Formula

Monthly Savings = Current Payment − New Payment; Break-even (months) = Closing Costs / Monthly Savings

Closing Costs

total refinance fees paid upfront or rolled into loan Description

Monthly Savings

current payment − new payment Description

Break-even

months needed for savings to cover closing costs Description

•A refinance often makes more sense when you plan to keep the loan beyond the break-even point.

•Resetting to a longer term can lower the payment but increase total interest paid.

Example Calculation

Current payment$2,350/month

New payment$2,100/month

Closing costs$6,000

Calculated Outcome

Break-even point

≈ 24 months

If you expect to sell or refinance again before the break-even point, refinancing is less likely to pay off.

Should You Refinance Your Mortgage?

Refinancing is usually about one of three goals: lowering the rate, changing the term, or changing the loan structure. The “right” choice depends on time horizon and costs.

Break-even matters: A great rate doesn’t help if you move or refinance again before costs are recovered.
Term tradeoff: Extending the term can lower the payment but increase total interest; shortening the term can raise payment while reducing total interest.
Closing costs are real: Include points and fees, not just the rate.

Quick Checklist Before Refinancing

Confirm your expected time in the home (or how long you’ll keep the loan).
Compare APR and total cost, not just the headline rate.
Model both “costs paid upfront” and “costs rolled into the loan” scenarios.
