How this is calculatedmethodology

Both the current and new loans are amortized from the same balance. Monthly savings is the difference in payments; the break-even is how many months of those savings it takes to recoup your refinance costs. Lifetime interest saved nets the new loan's total interest plus costs against the current loan's remaining interest.

M = P · r · (1 + r)ⁿ / ((1 + r)ⁿ − 1)
P
The loan balance being refinanced.
r
Monthly interest rate = annual rate ÷ 12.
n
Number of monthly payments in the term.
  • Compares the same balance at two rates/terms
  • Break-even = costs ÷ monthly savings

How to use the refinance calculator

  1. Enter your current loan balance, rate, and how many months remain.
  2. Enter the new rate and term you’re considering, plus estimated refinance costs.
  3. Check your monthly savings and the break-even month — the point where savings cover the closing costs.

TipIf you’ll move or pay off the loan before the break-even month, refinancing may not be worth it.

How to use the refinance calculator

Enter your current loan balance, your current rate, and the remaining term in months (the calculator shows the equivalent years beneath the field). Then add the new rate and new loan term you have been quoted, plus the refinance costs — closing costs, origination, and any points. The large readout shows your monthly savings, and the cells below break out the new payment, current payment, break-even point, and the total interest you would save or lose over the life of the loan.

The status banner gives you a plain-language verdict: whether the refinance raises your payment, or how long it takes to recoup your costs before the savings start adding up. Open the amortization schedule to see the new loan month by month, and use the export buttons to download it as a real Excel workbook or CSV, print it to PDF, or copy a link that reopens the calculator with your exact numbers.

How refinance math works and what to watch

Both loans are amortized from the same balance: each one is the level monthly payment that pays the balance to zero over its term. The difference between the two payments is your monthly savings. Dividing your refinance costs by that savings gives the break-even point — the month after which the refinance is genuinely putting money back in your pocket.

A lower rate almost always lowers the payment, but the term is the hidden lever. Refinancing a balance with 25 years left into a fresh 30-year loan resets the clock and can raise total interest even though the rate dropped. That is why the calculator reports lifetime interest savedafter subtracting your costs: it nets the new loan's total interest plus costs against the interest remaining on your current loan, so you see the true long-run picture, not just the monthly headline.

Estimates for education only — not a loan offer or financial advice. Actual payments and costs depend on your lender, credit, taxes, escrow, and fees.

Frequently asked questions

Is refinancing worth it?

Refinancing is worth it when the monthly savings recoup your closing costs well before you plan to sell or pay off the loan, and when the new total interest (including those costs) is lower than what you would have paid on your current loan. A lower rate is the usual driver, but watch the term: stretching a 25-year balance back out to 30 years can lower the payment while raising lifetime interest. Compare the break-even month and the lifetime-interest-saved figure together, not the rate alone.

What is the break-even point?

The break-even point is how long it takes for your monthly savings to add up to the cost of refinancing. It is simply your refinance costs divided by your monthly savings — for example, $4,000 in costs and $200/month in savings break even in 20 months. If you expect to keep the loan past the break-even point, the refinance starts saving you money from then on; if you might move or refinance again sooner, you may not recover the costs.

Does refinancing reset my loan term?

Yes — a refinance replaces your old loan with a brand-new one, so the term starts over from the new loan term you choose. If you have 25 years left and refinance into a fresh 30-year loan, you have effectively added five years of payments. That lowers the monthly payment but can increase total interest even at a lower rate. To avoid resetting the clock, choose a new term close to your remaining term, or refinance into a shorter term if the payment still fits your budget.
