Mortgage Points Explained: When Buying Points Is Worth It (and When It's a Trap)

What Are Mortgage Points?

Mortgage points (also called 'discount points') are upfront fees you pay to your lender at closing to reduce your interest rate. One point equals 1% of your loan amount — on a $400,000 mortgage, one point costs $4,000. In exchange, your interest rate is typically reduced by 0.25% (though the exact reduction varies by lender and market conditions). Points are essentially prepaid interest: you're paying more upfront to pay less each month over the life of the loan. They appear in Section A on Page 2 of your Loan Estimate. Points are tax-deductible in most cases, which can reduce the effective cost. The critical question isn't whether points lower your rate — they do — but whether the savings justify the upfront cost for your specific situation.

The Break-Even Formula

The break-even period tells you how long it takes for the monthly savings from a lower rate to recoup the upfront cost of buying points. The formula is simple: Break-Even Period (months) = Cost of Points ÷ Monthly Savings. For example, if one point costs $4,000 and reduces your monthly payment by $95, the break-even period is $4,000 ÷ $95 = 42 months (about 3.5 years). If you stay in the home and keep the loan for longer than 42 months, the points save you money. If you sell or refinance before 42 months, you've lost money on the points. As a general rule of thumb, financial advisors consider a break-even period under 5 years to be favorable. Anything over 7 years is usually not worth the upfront investment.

Real Example: When Points Make Sense

Consider a $400,000 30-year fixed-rate mortgage. Without points, the rate is 7.0% and the monthly principal and interest payment is $2,661. With one point ($4,000), the rate drops to 6.75% and the monthly payment drops to $2,594 — a savings of $67 per month. The break-even period is $4,000 ÷ $67 = 60 months (5 years). If you plan to keep this home and this mortgage for 10 years, you'll save $67 × 120 months = $8,040 in total payments, minus the $4,000 cost of points = $4,040 net savings. With two points ($8,000), the rate might drop to 6.50%, with a monthly payment of $2,528 — saving $133/month. Break-even: $8,000 ÷ $133 = 60 months. Over 10 years: $133 × 120 = $15,960 − $8,000 = $7,960 net savings. In this scenario, points are a solid financial decision.

Real Example: When Points Are a Trap

Now consider a different scenario. You're buying a starter home and expect to move or refinance within 3–4 years. The same $400,000 loan with one point costs $4,000 upfront and saves $67/month. Over 3 years (36 months), you save $67 × 36 = $2,412 — but you paid $4,000, so you lose $1,588. Points are also a trap when lenders use them to make their offer appear more competitive. A lender quoting 6.75% with one point is actually more expensive than a lender quoting 7.0% with no points if you plan to sell within 5 years. Some lenders will aggressively recommend points because the upfront payment improves their yield — they earn more money when you buy points. Always run the break-even calculation yourself before agreeing to purchase points.

Lender Credits: The Opposite of Points

Lender credits work in reverse: instead of paying money upfront to lower your rate, you accept a slightly higher rate and the lender pays some of your closing costs. For example, accepting a rate of 7.25% instead of 7.0% might come with $2,000–$4,000 in lender credits that offset your closing costs. This strategy makes sense when you expect to refinance or sell within a few years, when you want to minimize cash out of pocket at closing, or when you believe rates will drop and you'll refinance soon. The trade-off is a higher monthly payment — typically $25–$60 more per month for each 0.25% rate increase. Lender credits appear as negative numbers in Section A of your Loan Estimate.

How to Spot Points on Your Loan Estimate

Points appear in Section A ('Origination Charges') on Page 2 of your Loan Estimate. They're typically labeled as '% of Loan Amount (Points)' or 'Discount Points.' The dollar amount and the percentage should both be clearly stated. If you didn't request points and they appear on your LE, ask your lender why. Some lenders include points in their initial quote to make the rate look lower — this is legal but misleading. When comparing Loan Estimates from different lenders, make sure you're comparing quotes with the same number of points. A quote at 6.75% with 1 point and a quote at 7.0% with 0 points are NOT equivalent — you need to calculate the break-even to determine which is actually cheaper.
