Compare the payment and the debt you will still owe
Use this refinance break-even calculator to model a rate-and-term refinance with cash-paid and financed costs. Compare simple payment break-even with a balance-aware result over your holding period.
Your scenario estimate
Complete the numbered sections, then select Calculate.
- Current modeled P&I + MI
- Proposed P&I + MI
- New principal including financed costs
- Total entered economic costs
- Simple total-cost / initial-savings break-even
- First balance-aware break-even within holding period
- Cumulative payment difference minus cash-paid costs
- Balance-aware benefit at holding period
- Current-loan balance at holding period
- New-loan balance at holding period
- Modeled remaining current interest
- New full-term interest
Simple break-even is a cash-flow convention, not the full economic answer. Balance-aware benefit includes the different debt balances and financed fees. Payments stop when each modeled loan is paid off; holding-period benefits can reverse.

How to Use the Refinance Break-Even Calculator
Step 1: Current mortgage
Enter current principal balance, fixed rate, remaining months and monthly mortgage insurance. P&I is calculated as an amortizing payment over the entered remaining term. This may differ from your statement if you made extra principal payments without recasting; this model is not intended for that case.
Step 2: Proposed refinance
Enter the new fixed rate and term. Split genuine transaction costs into cash-paid and financed amounts after credits. Include points and any applicable penalty once. Exclude escrow deposits and refundable escrow balances from economic fees. The new loan equals current balance plus financed costs.
Step 3: Comparison period
Enter the months you expect to keep the new loan. Review both cumulative payment savings and the balance-aware benefit at that same date. Taxes and homeowners insurance are assumed identical and omitted from both options.

How the Calculator Works
New principal = unpaid current balance + financed costs. Initial savings = current modeled P&I plus MI − new P&I plus MI. Simple break-even = all economic costs ÷ positive initial savings. Holding-period cash benefit = cumulative current payments − cumulative new payments − cash-paid costs. Balance-aware benefit adds current ending balance and subtracts new ending balance. Financed costs are captured through the new principal, payments and balance rather than subtracted twice.
Example calculation
With $300,000 unpaid principal and $2,000 financed costs, the new principal is $302,000. Another $3,000 paid in cash makes total entered costs $5,000. A payment-based break-even divides $5,000 by initial monthly savings; the balance-aware calculation also checks what each loan would still owe at the comparison date.
How to interpret your results
A positive balance-aware result means the modeled payment difference and debt position have recovered the cash-paid cost at that date. Negative values mean they have not. The first crossover is not a guarantee of lasting savings after a term reset.
Assumptions and factors that change the result
Fixed amortizing loans, no extra payments, cash-out, debt consolidation, ARM, credit clawback, tax benefit or investment return. Current P&I is recalculated from balance/rate/remaining months; do not use if that differs materially from your unrecast statement payment. MI is constant until payoff. True fees, not refundable escrows, enter economic costs.
Frequently asked questions
Do financed closing costs count?
Yes. They raise new principal and affect payments and the ending balance. They are included in the simple cost total but not subtracted again in the balance-aware formula.
Does a lower payment always save money?
No. Extending the term or financing costs can lower the initial payment while leaving more debt. Compare equal holding periods and balances.
