Resetting to a fresh 30 years is the usual reason a lower payment costs more overall

Break-even

1 yr 8 mo

The payment drops, but stretching the balance over a longer term costs more in total. Compare against how long you plan to keep the loan.

Monthly saving$270.00
Closing costs$5,200
Extra paid over the life$61,000
Remaining payments if you refinance360 months

Tip. If you might move before the break-even date, refinancing usually does not pay.

Assumptions

  • Break-even months = closing costs ÷ the monthly payment saving.
  • Lifetime comparison multiplies each payment by its remaining months, so a longer new term shows up as a higher total even when the payment drops.
  • Closing costs are paid upfront rather than rolled into the new balance.
  • Principal and interest only. Escrow for tax and insurance is excluded from both sides.

Examples and charts

Start with a scenario, then read the response curve to see which input actually moves the answer.

Example 1

Lower payment, fresh 30 years

The common offer: the payment falls and the clock restarts, which usually raises lifetime cost.

Months to recover closing costs

20 months

Example 2

Matching the remaining term

Refinancing into roughly the term you had left, which is the honest comparison.

Months to recover closing costs

40 months

Example 3

Large rate drop

A saving big enough to clear closing costs quickly even on a reset term.

Months to recover closing costs

11 months

Sweeps refinance closing costs from half to one and a half times your value, holding everything else fixed.

What this calculates

Finds how many months of payment savings it takes to recover refinance closing costs, and compares the lifetime cost of both loans so a longer new term cannot hide behind a lower payment.

How to use it

  1. Start with current monthly principal and interest and work down the form, or load an example to begin from a realistic case.
  2. Read the headline result alongside the supporting rows, which show the intermediate figures behind it.
  3. Check the assumptions. They decide what the number includes and, more importantly, what it leaves out.
  4. Sweep refinance closing costs on the response curve to see how much it actually moves the answer.
  5. Run a cautious case as well as an optimistic one before using the estimate in a decision.

Common mistakes

  • Ignoring how many more years you actually plan to keep the home.
  • Comparing payments without noticing that one includes escrow and the other does not.
  • Refinancing repeatedly and restarting the front-loaded interest schedule each time.

Formula

Break-even months = closing costs ÷ monthly saving; lifetime change compares each payment across its remaining months

Inputs

  • Current monthly principal and interest
  • New monthly principal and interest
  • Refinance closing costs
  • Months left on the current loan (mo)
  • New loan term (yrs). Resetting to a fresh 30 years is the usual reason a lower payment costs more overall

FAQ

Should I roll the costs into the loan?

It removes the cash requirement today and adds interest for the life of the loan. This break-even assumes you pay the costs upfront, so rolling them in makes the true recovery slower than shown.

Why does a lower payment sometimes cost more?

Because resetting to a fresh 30-year term stretches a balance you were already partway through. The lifetime figure on this page is there to catch exactly that.

Is a no-cost refinance really free?

No. The costs are paid through a higher rate instead of upfront cash. That can be the right trade on a short horizon, but the payment saving will be smaller than a priced-in-costs quote.

How do I find the months left on my current loan?

Your mortgage statement usually shows the maturity date. Count the months between now and then, or subtract the payments made from the original term.

Are these numbers financial advice?

No. They are educational estimates based on the inputs and assumptions on this page. Confirm important decisions with a qualified professional and your own documents.
