Mortgage Points Explained: When Are They Worth It?

How discount points work

A discount point is a fee you pay upfront to reduce your mortgage interest rate. One point equals 1% of your loan amount. On a $400,000 loan, one point costs $4,000. In exchange, your lender permanently lowers your interest rate — typically by 0.25%, though this varies by lender and market conditions.

Discount points are different from origination points. Origination points are a fee the lender charges for making the loan — you pay them and get nothing back in the form of a lower rate. Discount points are a trade: you pay more upfront to pay less every month. Both appear on your Loan Estimate and Closing Disclosure in Section A (Origination Charges), which is one reason homebuyers often confuse them.

Lenders price points based on how they sell loans on the secondary market. When rates are volatile or a loan type is in low demand, the cost to buy down your rate may be higher than the standard 0.25% per point. Always ask your lender to show you the full pricing grid — how many points to get each available rate — before deciding how many points to buy.

How to calculate your break-even period

The break-even period is how long it takes for your monthly savings to recoup the upfront cost of buying points. The formula is simple: divide the cost of the points by your monthly payment savings.

Here's a concrete example on a $400,000 loan at a 30-year fixed rate. Suppose your lender offers 7.00% at no points, or 6.75% for one point ($4,000). At 7.00%, your principal and interest payment is approximately $2,661/month. At 6.75%, it drops to approximately $2,594/month — a savings of $67/month. Dividing $4,000 by $67 gives a break-even of just under 60 months, or 5 years.

Your actual break-even is slightly longer than this simple calculation suggests, for two reasons. First, the $4,000 you spend on points could have been invested — its opportunity cost erodes your savings. Second, if you itemize deductions, mortgage interest is deductible but points may or may not be fully deductible in the year paid (consult a tax advisor). As a practical rule, add 10–15% to your simple break-even calculation to be conservative.

• Break-even formula: point cost ÷ monthly savings = months to break even
• Example: $4,000 cost ÷ $67/month savings = 59.7 months (~5 years)
• Adjust upward for opportunity cost of the cash spent on points
• Compare your break-even to your realistic expected hold period — not your ideal one

When buying points makes sense

Buying discount points is a rational choice when you're confident you'll keep the loan long enough to pass the break-even point — and when the rate reduction per point is fair given current market pricing.

The clearest case is a long-term homeowner who has extra cash at closing. If you're buying your forever home, plan to stay 10+ years, and can buy two points for $8,000 that drop your rate from 7.00% to 6.50%, your monthly savings might be $140/month. At that rate, you break even in under 5 years and save over $50,000 in interest over 30 years. The math is compelling.

Points also make more sense in high-rate environments. When rates are at historically elevated levels, a meaningful rate reduction has more impact because your base payment is already large. Reducing a 7.5% rate by 0.5% saves more dollars per month than reducing a 4% rate by the same amount.

If you have cash reserves beyond your emergency fund and down payment, and your alternative is leaving it in a savings account earning less than the effective return on your points investment, buying points can be a conservative, guaranteed-return use of that capital.

When buying points does NOT make sense

Points are a bad investment if you might not keep the loan long enough to break even. Life changes — job relocations, family growth, income changes — happen more often than people expect. Most homeowners refinance or move before the 10-year mark. If there's a realistic chance you'll sell or refinance within 5 years, the upfront cost of points is likely money left on the table.

Buying points when you're cash-constrained is a common mistake. Points paid at closing reduce your liquid reserves, which you'll need for moving costs, immediate repairs, and the financial surprises that come with homeownership. A lower rate won't help you if you can't cover a $3,000 HVAC repair 6 months in.

Watch for lenders charging more than one point per 0.25% rate reduction. If a lender quotes you 1.5 points for a 0.25% reduction, the break-even is 50% longer than the standard. This is not a market standard — it's a lender capturing extra margin. Get competing quotes to verify the points-to-rate ratio you're being offered is reasonable.

An alternative worth considering is lender credits — the reverse of discount points. Instead of paying more upfront for a lower rate, you accept a slightly higher rate in exchange for a credit that reduces your closing costs. If your break-even on points is 7 years and you're only planning to stay 5, lender credits may be the smarter structure. Ask your lender to show both options side by side.

• Don't buy points if you might sell or refinance within 5 years
• Don't buy points if it depletes your cash reserves below a comfortable buffer
• Verify the rate reduction per point is close to market standard (~0.25% per point)
• Ask your lender about lender credits as an alternative to buying points
• Get competing quotes — the points-to-rate ratio varies meaningfully between lenders
