A loan officer offers you a quarter-point lower rate for $4,800 at closing. The monthly savings sound great. The question nobody asks at the closing table is whether you will live in the house long enough for that $4,800 to ever come back to you.

Discount points are a real product, sold under the same name across nearly every lender, and they work the same way: you pay cash up front to buy a permanent reduction in your interest rate. The math is simple. The decision is not, because most homeowners never run the breakeven calculation that determines whether the trade actually pays off.

> One discount point equals 1% of your loan amount and typically lowers your rate by about 0.25 percentage points. The breakeven on most point purchases falls between five and seven years of holding the loan.

What a Discount Point Actually Buys You

A point is 1% of your loan principal. On a $400,000 mortgage, one point costs $4,000. Two points cost $8,000.

In return, your lender lowers your interest rate, usually by around 0.125 to 0.25 percentage points per point purchased. The exact ratio varies by lender and by market conditions. Always ask for the specific rate reduction in writing, not the verbal offer.

The lower rate stays with the loan for its entire life or until you refinance or sell. That permanence is the asset you are buying. The cost is real cash at closing that cannot come back if your situation changes.

For a $400,000 loan at 6.75% versus 6.50% (the result of buying one point), your monthly principal and interest payment drops from approximately $2,594 to about $2,528. That is roughly $66 per month in savings. Spread across the next 30 years, the total interest saved is around $23,800. The cost was $4,000.

On paper this looks like an obvious win. The catch is the breakeven.

The Breakeven Math That Actually Matters

The breakeven point is the number of months it takes for your monthly savings to equal the upfront cost. In the example above, $4,000 divided by $66 per month equals about 60 months, or 5 years.

That number changes everything. If you sell or refinance before month 60, you lost money on the points. If you stay past month 60, you start banking the savings.

The median American homeowner sells or refinances roughly every 8 to 12 years according to data from the Mortgage Bankers Association. That suggests buying points often does pay off. But the median hides a wide spread, and your situation is what matters, not the average.

Two questions decide the math:

• How long will you actually keep this loan? Not how long you think you will stay in the house. How long you will keep this specific mortgage. A refinance ends the points permanently with no refund of what you paid.
• What are competing returns on that cash? $4,000 at closing is $4,000 you cannot put toward your emergency fund, your down payment cushion, or your retirement account. A 5% return on that capital elsewhere may compete favorably with the rate savings.

When Paying Points Makes Real Sense

Buying points is a strong move under specific conditions. You plan to stay in the home long-term, well past the breakeven. You have stable income and no reason to refinance in the next 7 to 10 years. You have already maxed out other capital uses, including emergency reserves and retirement contributions. Mortgage rates are high relative to historical norms and you do not expect to refinance into a meaningfully lower rate within the breakeven window.

Points also become more attractive at higher loan amounts. The percentage cost stays constant, but the absolute monthly savings grow with the loan size. On a $700,000 mortgage, the same point trade saves more in dollar terms even though the percentage relationship is identical.

For homeowners taking advantage of seller-paid concessions, points become especially compelling. If a seller is contributing to closing costs as part of the negotiation, redirecting that concession toward points often produces better long-term value than reducing other closing fees.

> Points are also tax-deductible in most cases on a primary residence purchase, which improves the breakeven slightly. Confirm with a tax professional, but the IRS generally allows the full deduction in the year paid for new home purchases that meet specific criteria.

When You Should Walk Away From Points

There are times when paying points is the wrong call regardless of the marketed savings. If you might sell or refinance within 5 years, the math almost never works out. If your cash reserves after closing would drop below 3 months of expenses, the points are too expensive in liquidity terms even if the rate math looks good. If rates are high and likely to fall, the points lock in a permanent payment for what may become a temporary problem.

Loan officers earn the same compensation whether you buy points or not in most cases, so they are usually neutral on the recommendation. The risk is that the savings are presented in monthly payment terms (“$66 a month for life!”) without the corresponding breakeven framing (“if you stay 5 years”). Always force the breakeven calculation into the conversation.
