Is it worth refinancing for 1 percent? Break-even examples

Refinancing for 1 percent is often worth it if you'll stay in the home long enough to break even. On a $300,000 loan, dropping from 8% to 7% saves about $205 a month. With closing costs of 3% ($9,000), you'd break even in roughly 44 months. But if you're already years into your loan, a new 30-year term can wipe out the savings. Run your numbers in our refinance break-even calculator.

Here's the math for several common situations, including the term-reset trap.

The basic break-even formula

The simple break-even point is:

Closing costs ÷ monthly savings = months to break even

If you stay in the loan longer than that, refinancing likely pays off. If you sell or refinance again sooner, you probably lose money on the deal.

Closing costs typically run 2% to 5% of the loan amount. On $300,000, that's $6,000 to $15,000. We'll use 3% ($9,000) in the examples below.

Example 1: a recent loan, 8% to 7%

Say you took out a $300,000, 30-year loan at 8% recently. You still owe close to $300,000 with almost all 30 years left. You refinance into a new 30-year loan at 7%.

	Current loan	New loan
Balance	$300,000	$300,000
Rate	8.00%	7.00%
Term left	30 years	30 years
Monthly principal and interest	$2,201.29	$1,995.91
Monthly savings		$205.39
Closing costs (3%)		$9,000
Simple break-even		44 months
Remaining interest	$492,466	$418,527

That's a clear win if you plan to stay. You'd save about $64,939 over the life of the loan, after paying the $9,000 in costs.

Our calculator also shows a "true" break-even that counts how fast each loan builds equity. Here, it comes in sooner, at about 36 months. The lower rate means more of each payment goes to principal from day one.

Example 2: five years in, and the term reset problem

Now say you're five years into your loan. You owe $300,000 at 8% with 25 years left. Your payment is $2,315.45.

You have two choices: refinance into a new 30-year loan, or into a 25-year loan that keeps your original payoff date.

	Keep current loan	New 30-year at 7%	New 25-year at 7%
Monthly payment	$2,315.45	$1,995.91	$2,120.34
Monthly savings		$319.54	$195.11
Simple break-even		29 months	47 months
Total payments left	$694,635	$718,528	$636,102
Lifetime savings after $9,000 costs		−$32,892	$49,533

The 30-year option looks best on a monthly basis. It saves $320 a month and breaks even on paper in 29 months. But it adds five years of payments. Over the full term, you'd pay about $32,900 more than if you'd kept your current loan.

The 25-year option saves less each month but comes out about $49,500 ahead over its life.

The lesson: monthly savings and lifetime savings aren't the same thing. When you refinance, compare loans with similar payoff dates. Or plan to keep paying your old payment amount on the new loan.

How the size of the rate drop changes things

The same $300,000 loan at 8%, refinanced into a new 30-year loan with $9,000 in costs:

New rate	Rate drop	Monthly savings	Simple break-even
7.50%	0.5%	$103.65	87 months
7.00%	1.0%	$205.39	44 months
6.50%	1.5%	$305.09	30 months

A half-point drop takes over seven years to break even with 3% costs. A full point takes under four years. That's why the old "refinance for 1%" rule of thumb has stuck around. It's not a law, though. Your costs and timeline matter more than the rule.

Costs move the break-even too

If your closing costs are lower, you break even sooner. Using Example 1 ($205.39 monthly savings):

• $6,000 in costs (2%): about 30 months
• $9,000 in costs (3%): about 44 months
• $15,000 in costs (5%): about 74 months

Ask lenders for a Loan Estimate and compare the "Total Closing Costs" line. The CFPB explains how to read one at consumerfinance.gov.

Should you roll the costs into the loan?

Many lenders let you add closing costs to the new balance. You keep your cash, but you borrow more and pay interest on the costs for years.

In Example 1, rolling $9,000 into the loan would make the new balance $309,000. The payment would rise by about $60 a month, to $2,055.78, so your monthly savings would shrink to roughly $146. There's no upfront check to write, but you'd pay interest on that $9,000 for as long as you keep the loan.

A "no-closing-cost" refinance is another version of the same trade. The lender covers the fees in exchange for a higher rate. That can make sense if you expect to move or refinance again within a few years. If you plan to stay a long time, paying the costs upfront usually comes out cheaper.

When a 1% refinance may not be worth it

• You may move within a few years. If you sell before break-even, you lose money.
• You're far into your loan. Most of your payment is already principal. A new long term restarts the interest-heavy years.
• Your closing costs are high. At 5% costs, even a 1% drop takes over six years to break even.
• You'd pay points to get the rate. Points raise your upfront cost and push break-even out.
• You're stretching to lower the payment. If the goal is cash flow, that's fine. Just know it can cost more over time.

When it often makes sense

• You plan to stay well past the break-even point.
• You can keep your payoff date the same or shorter.
• You can drop PMI or switch from an adjustable rate to a fixed one at the same time.
• Your credit has improved since you first borrowed, so you qualify for a better rate.

Current 30-year fixed rates averaged 7.32% in late October 2026, according to Freddie Mac. If your rate is around 8% or higher, it may be worth getting quotes.

Bottom line

A 1% lower rate can save you a lot, but only if you stay past the break-even point and don't reset your clock too far. On $300,000, expect roughly $200 a month in savings and a break-even around three to four years with typical costs.
