What is the refinance break-even point?

It's how many months of lower monthly payments it takes to pay back your closing costs. Break-even months = closing cost ÷ monthly savings. If you'll keep the loan longer than that, refinancing saves you money.

Should I refinance to a longer or shorter term?

A shorter term raises your monthly payment but cuts total interest and shortens payoff. A longer term lowers the payment but can increase total interest. Compare total lifetime cost, not just the monthly payment.

What if the new rate is higher?

Then there is no monthly savings and no break-even — refinancing at a higher rate generally makes no sense unless you're changing term or taking cash out for a specific purpose.

Does refinancing pay for itself?

Refinancing is a trade of a known cost (closing fees) for an uncertain benefit (a lower payment). The tool that settles it is the break-even: how long until the monthly savings repay the upfront cost. If you'll stay in the home and keep the loan past that point, you win; if you'll leave before it, the refinance loses money.

The break-even formula

Refinance break-even months = closing costs ÷ monthly payment savings. If your closing costs are $6,000 and you save $400/month, you break even in 15 months. That's the single number that answers "is it worth it."

Term matters more than you think

Many people only look at the monthly payment. But the new term changes the math dramatically:

Same term, lower rate: payment drops, total interest drops — almost always good.
Longer term, lower rate: payment drops more, but you pay interest longer; total interest can actually rise.
Shorter term, lower rate: payment may stay about the same, but you pay the loan off faster and save far more interest over the long run.

So the tool shows both monthly savings and total interest impact — because a payment drop is not the same as a win.

When refinancing is a bad idea

You can't recover the costs in time. If the break-even is longer than your expected stay, it's a loss.
You're extending a year of payments. Resetting to a fresh 30-year term means years of mostly-interest payments; consider keeping a similar remaining term.
The rate is actually higher. If the new rate equals or exceeds your current one, there's no monthly savings at all.

Methodology & sources

Payments use standard amortization. Defaults: current rate 7.5% (illustrative), new rate uses the Freddie Mac PMMS 30-year fixed average (6.70% as of early September 2026). Closing costs are estimated as a percentage of the loan; real costs vary by lender and state.

Frequently asked questions

How do I know my true closing costs?

Lenders give a Loan Estimate (LE) early in the process. Typical refinance closing costs run 2–5% of the loan — this tool uses your percentage input; enter the real figure from your LE for accuracy.

Cash-out refinance — is that different?

Yes. Cash-out refinancing takes equity out as cash, which raises your balance and can undo the benefit. This tool models a rate-and-term refinance (same principal), not cash-out.

Does timing matter?

Rates move weekly. If you lock when rates fall, the break-even shortens. Run the tool monthly and compare.
