Mortgage Points: When Paying Upfront for a Lower Rate Actually Pays Off

By Smart Budget Sheets November 10, 2026
One formula to decide whether paying points for a lower mortgage rate is worth it.

Lenders often offer a lower rate if you pay “points” at closing. One point usually costs 1% of the loan amount. Whether that’s a good deal comes down to one number: how many months it takes for the lower payment to repay what you paid upfront.

1. The break-even formula

Break-even months = cost of the points ÷ monthly payment saving.

Example: a $300,000, 30-year loan. At 7.00% the principal-and-interest payment is about $1,996 a month. If one point ($3,000) brings the rate to 6.75%, the payment drops to about $1,946. The saving is roughly $50 a month, so the break-even is about 60 months, or 5 years.

2. Compare break-even with how long you’ll keep the loan

If you expect to sell or refinance before the break-even date, the points cost more than they save. Many people refinance when rates fall, which cuts the useful life of points short.

3. Check what the cash could do instead

The same $3,000 could go toward a larger down payment, a repair fund, or emergency savings. A thin cash cushion right after buying a home is a common source of new credit card debt.

4. Get the offer in writing for each option

Ask for a Loan Estimate with and without points so you compare the same fees side by side. Look at the rate, the points line and the total closing costs, not just the headline rate.

5. Mind the tax angle, but don’t rely on it

Points on a home purchase may be deductible in some cases, but only if you itemize. Treat any tax benefit as a bonus, not the reason to buy points.
