Is Buying Mortgage Points Worth It? The Break-Even Math
At the closing table you'll be offered a choice: pay more cash now ("buying points") to get a lower rate for the life of the loan. Lenders present it as a discount. Sometimes it is one. Sometimes it's just prepaying interest you'll never use. The whole decision reduces to a single number: the break-even month.
What a point actually is
One mortgage point = 1% of the loan amount, paid at closing, in exchange for a rate reduction — typically about 0.25% per point, though the exact exchange rate varies by lender and market. On a $300,000 loan, one point costs $3,000 and might drop your rate from 6.50% to 6.25%.
The break-even calculation (60 seconds)
- Cost: points × 1% × loan amount. Two points on $300,000 = $6,000.
- Monthly saving: payment at the lower rate minus payment at the higher rate. Two points dropping 6.50% → 6.00% on a 30-year $300K loan saves about $95/month.
- Break-even: $6,000 ÷ $95 ≈ 63 months — about 5.3 years.
That's the entire decision: if you'll keep the loan past month 63, the points win; before that, they're money burned. Model your own price and rate pair in the mortgage calculator — calculate the payment at both rates and divide the point cost by the difference.
When buying points loses money
- You sell or refinance early. Americans hold mortgages far shorter than their terms — the median 30-year loan is refinanced or ended within roughly 7–10 years. If your expected hold is 5 years, points priced at a 9-year break-even are a loss.
- Rates fall. If you refinance at a lower market rate in 3 years, the expensive rate you bought down disappears with it.
- The cash has a better use. $6,000 keeping your emergency fund intact or paying off a 22% credit card beats buying a 0.5% mortgage discount every time.
- You're stretching to afford them. Points are paid at closing, on top of the down payment. Borrowing or draining reserves to buy points defeats the purpose.
When points are clearly worth it
- Forever-home, long horizon. Planning 15+ years in the home with no refinance intent? Points keep paying every month past the break-even, often netting tens of thousands over the loan.
- You have surplus closing cash. If the money would otherwise sit in a 4% savings account, a bought-down mortgage rate "returns" its equivalent yield — at a locked-in, risk-free benefit, once you're past break-even.
- Stable, high-rate environment. When rates are unlikely to fall soon, the refinance risk shrinks and the hold period extends.
Two negotiation notes most borrowers miss
Points are negotiable across lenders. The rate-per-point exchange isn't standardized — lender A may offer 0.25% per point while lender B offers 0.375%. When comparing quotes from multiple lenders, ask each one the same question: "What rate reduction do I get per point?" The answer varies more than borrowers expect.
Check the "zero-point, zero-fee" alternative. Some lenders offer no-point loans at a slightly higher rate. If the rate gap is small (0.125% or less), skipping points is often smarter — you keep flexibility and every refinance option open.
Points are a bet on how long you'll keep this exact loan. If you can't state your expected hold time with reasonable confidence, don't place the bet.
Bottom line
Compute the break-even month, compare it to your realistic hold period, and only buy points when there's a multi-year cushion between the two. For long-horizon owners with spare closing cash, points are one of the few genuinely risk-free "investments" in the mortgage process. For everyone else, the flexibility of a no-point loan is worth more than the discount. Related: how 15- and 30-year terms compare on total cost.
