Should You Refinance? Find Your Break-Even Point

The number that actually decides a refinance

The refinance question isn't "is my new rate lower?" — it's "how long until the savings pay back the closing costs?" That's your break-even point. If you'll stay in the home well past it, refinancing usually makes sense. If you might move before then, the closing costs could outweigh the savings.

This calculator does the full math: it compares your current and new monthly payments, divides your closing costs by the monthly savings to find the break-even month, and shows the lifetime difference so you can see the catch that lenders rarely highlight — extending your term can lower your payment while increasing total interest paid.

Watch the term reset

Refinancing a loan with 27 years left into a fresh 30-year term lowers your payment partly because you're stretching repayment over more years. That can be the right call for cash flow, but always compare the lifetime numbers, not just the monthly payment, so you know the true cost.

Making sense of your refinance numbers

A break-even figure on its own can feel abstract, so it helps to know what the result is actually telling you and what to do with it. The sections below walk through reading the output, gathering the right paperwork beforehand, and recognizing the situations where refinancing quietly costs you money. None of this is financial advice; it is general education to help you ask sharper questions of a licensed professional.

How to read your break-even result

The break-even point is the simplest, most honest test of a refinance. Take your total closing costs and divide them by your monthly savings, and the answer is the number of months it takes for the lower payment to repay what the refinance cost you. If your closing costs are $6,000 and you trim $250 off your payment each month, you cross break-even at roughly 24 months. Before that month arrives, you are still in the red; the savings have not yet covered the upfront expense. After it, every month of lower payments is money you keep.

That is why the length of time you plan to stay in the home matters more than the rate itself. Refinancing pays only if you remain in the loan well past the break-even month. If you suspect you might sell, move, or refinance again before then, the math often says wait, even when the new rate looks attractive.

What to gather before you refinance

Good decisions start with accurate inputs. Pull together your current interest rate, your remaining balance, and how many years are left on your existing loan, since those three figures drive your current payment. Add a realistic estimate of closing costs, which commonly land between two and five percent of the loan amount and may include origination fees, appraisal, title, and recording charges.

Then shop. Request a Loan Estimate from at least three lenders. The Loan Estimate is a standardized, government-mandated form, so the same line items appear in the same places on every one, which makes side-by-side comparison straightforward rather than guesswork. The Consumer Financial Protection Bureau (CFPB) publishes guidance on how to read each section. Comparing standardized Loan Estimates is the single most effective way to see who is genuinely cheaper once every fee is counted, not just who advertises the lowest headline rate.

When refinancing doesn't pay

Several common situations turn a tempting rate into a poor deal. The first is a short remaining tenure: if you have only a few years left on your mortgage, you may never reach the break-even month before the loan is paid off anyway. The second is restarting the loan term. Refinancing a loan with twenty-seven years left into a fresh thirty-year term can lower your payment while stretching repayment over more years, which often raises the total interest you pay across the life of the loan.

Weakened credit since your original mortgage can also work against you, because a lower score may mean the new rate is not as low as you hoped, shrinking or erasing your monthly savings. Finally, be wary of rolling closing costs into the balance instead of paying them upfront. It feels painless, but it increases the amount you finance and the interest charged on it, pushing your real break-even further out than the simple division suggests. When any of these apply, the lifetime number, not the monthly payment, tells the truer story.
