Mortgage lenders love to dangle discount points as a way to "lower your rate," but the upfront cost can run thousands of dollars on a typical home loan.
Whether that trade pays off depends entirely on how long you plan to stay put — and most buyers never run the numbers before signing.
One discount point costs 1% of your loan amount and typically shaves about 0.25% off your interest rate.
On a $400,000 mortgage, that's $4,000 upfront to drop your rate from, say, 6.75% to 6.5%.
Your monthly payment falls by roughly $64.
Divide the upfront cost by the monthly savings and you get your break-even: about 62 months, or just over five years.
Stay in the home longer than that and you come out ahead.
Sell or refinance before then and you've handed the lender free money.
The math shifts fast with bigger buydowns.
Two points on that same loan cost $8,000 and might cut the rate by 0.5%, saving around $128 a month.
Break-even stretches to roughly 63 months — similar timing, but far more cash locked up at closing.
That upfront cash matters more than ever.
With average 30-year rates hovering in the mid-6% range and home prices still elevated, many buyers are scraping together down payments and closing costs already.
Draining savings for points can leave you with no cushion for a furnace replacement or a surprise medical bill.
If rates fall in two or three years, you'll likely refinance — and those points vanish.
You paid for a lower rate you no longer have.
Points can still make sense in specific cases.
If you're buying a forever home, have cash beyond your emergency fund, and plan to stay 10+ years, the lifetime savings add up.
On a $400,000 loan held for 15 years, one point could save roughly $7,500 after the break-even point — real money.
The alternative is a no-points loan: you keep the cash, accept the slightly higher rate, and preserve flexibility.
You can always make extra principal payments to reduce total interest without paying the lender upfront.
That approach keeps your options open if life changes.
One more wrinkle: points on a purchase mortgage are often tax-deductible in the year you pay them, while points on a refinance usually must be deducted over the loan's life.
Ask a tax professional about your situation before assuming a write-off.
Before you decide, ask your lender for a side-by-side Loan Estimate showing both scenarios.
Compare the total cost over your realistic time horizon, not just the monthly payment.
The lower rate isn't automatically the better deal — it's just the one that's easier to sell.
Our take: unless you're certain you'll stay past the break-even and have cash to spare, skipping points is the safer play.
Final Thoughts
Flexibility is worth something, and in a market this unpredictable, keeping your savings liquid beats chasing a slightly smaller payment.
