Refinance Calculator
See if refinancing will save you money.
Current loan
Pick the path that matches what you know: payoff figures from your statement, or original loan amount and amortization terms.
Use the principal-and-interest part of your mortgage payment, not taxes, insurance, or HOA. We derive months remaining from balance, rate, and this payment (fixed-rate amortization).
Enter your actual monthly payment (principal and interest) for the best estimate. With $0 here we use a placeholder timeline (~360 mo) to illustrate numbers, add your real payment for an accurate payoff estimate.
New loan terms
2026: roughly 5.5%–6.2% typical, verify with quotes.
Third-party + lender fees (typ. $2k–$5k). Paid at closing unless you roll them into the loan below.
Common on refinance quotes (e.g. 2% ≈ two points on the loan amount). Cash at closing unless rolled in.
Adds to new loan principal.

Interest rate here is the contract rate used for your monthly principal-and-interest payment on the new loan amount. Lenders often quote a higher APR on the new loan because APR reflects prepaid finance charges (points and many closing costs), not because your monthly payment is calculated with a different rate. Our Est. APR approximates that when you pay closing costs out of pocket (not rolled into the loan). The APR on your Loan Estimate can still differ slightly. Totals above use the interest-rate scenario for payments (principal and interest only).

Refinance Calculator: Master Break-Even Analysis in 2026
Calculate mortgage refinance break-even point, monthly savings, and total interest comparison. How to calculate refinance break-even. Determine if refinancing saves money. No sign-up, all calculations run locally.
What This Calculator Does
- Who It Helps:Homeowners considering a rate-and-term refinance, borrowers evaluating cash-out refinancing, and anyone comparing no-cost refinance offers against traditional closing-cost structures.
- Key Outputs:Break-even point in months (with risk classification: under 24 months, 24–48 months, or over 48 months), monthly payment savings, total interest remaining on each loan, net lifetime benefit after closing costs, and a clock-reset warning when applicable.
- What It Does Not Do:The calculator does not pull live mortgage rates, factor in tax deductions on mortgage interest, or model adjustable-rate scenarios. It assumes fixed-rate loans with standard monthly amortization.
How the Math Works
- Net Lifetime Benefit:Total interest remaining on the current loan minus total interest on the new loan, minus refinance closing costs. A positive value means refinancing saves money over the full term.
- Clock-Reset Check:If the new term extends beyond the current payoff date, the calculator warns that you are adding months of interest. A shorter-term refinance (e.g. 15 or 20 years) often produces a better net benefit even with higher payments.
- Worked Example:$250,000 balance at 6.5% with 25 years remaining (current PMT ≈ $1,691). Refinance to 5.8% for 25 years, $4,000 closing costs. New PMT ≈ $1,582. Monthly savings = $109. Break-even = $4,000 ÷ $109 ≈ 37 months. Net lifetime benefit ≈ $28,700 after closing costs.
How to Use This Calculator
- Cash-Out Amount (optional):If you plan to borrow more than your current balance, enter the additional cash-out amount. This increases the new loan balance and affects monthly savings and break-even calculations.
- Mortgage Points (optional):Enter the number of points you plan to buy. Each point costs 1% of the loan amount and typically reduces the rate by about 0.25%. The calculator factors point costs into closing costs and break-even.
- Review Break-Even Results:Check the break-even period and its risk classification: under 24 months (strongly recommended), 24–48 months (market dependent), or over 48 months (high risk). Compare only if you expect to stay past break-even.
- Total Interest Comparison:View total interest remaining on your current loan versus the new loan, the net lifetime benefit after closing costs, and any clock-reset warning if the new term extends your debt timeline.
