Should I buy points on my mortgage?

Buy mortgage points if you plan to keep the loan long enough for the monthly savings to exceed the upfront cost — typically 3–7 years depending on the rate reduction offered. If you expect to sell or refinance before break-even, skip the points.

Whether to buy mortgage points is a break-even math problem. One discount point costs 1% of your loan amount and typically lowers your interest rate by a small fraction — the exact amount depends on the lender and market conditions. The question is simple: will you keep the loan long enough for the monthly savings to repay the upfront cost? The CFPB's guide on discount points walks through the core calculation.

The break-even calculation

Break-even month = upfront cost of points ÷ monthly payment savings. If you pay $4,500 in points (1.5 points on a $300,000 loan) and save $75/month in interest, break-even is 60 months (5 years). Keep the loan past 5 years and you come out ahead. Sell, pay off, or refinance before 5 years and you paid more than you saved.

Break-even example

$350,000 mortgage. Rate without points: 7.00%. Rate with 1 point ($3,500): 6.75%. Monthly savings: approximately $60/month. Break-even: 58 months (~4.8 years). If you plan to stay in the home 7+ years without refinancing, the point likely pays off. If you'll move in 3 years or refinance when rates drop, skip the points.

When buying points makes sense

When to skip points

Lender credits: the inverse of points

Lender credits are the opposite: the lender pays some of your closing costs in exchange for a higher interest rate. They make sense when you're cash-constrained at closing and expect to sell or refinance within a few years — you trade a higher rate for reduced upfront costs, betting the loan won't last long enough for the higher rate to cost more than the closing credit received.
