Mortgage points, also called discount points, let you pay upfront cash at closing to reduce your interest rate for the life of the loan. Whether paying points makes financial sense depends entirely on how long you keep the mortgage before paying it off or refinancing — a calculation most buyers don't run carefully before deciding.
What one point actually costs and saves
One mortgage point costs 1% of the loan amount and typically reduces your rate by approximately 0.25 percentage points, though the exact reduction varies by lender and market conditions. On a $400,000 mortgage, one point costs $4,000 and might reduce your rate from 7.25% to 7.00%, reducing your monthly payment by roughly $66. At that savings rate, it takes approximately 60 months — five years — to recover the $4,000 cost. If you sell or refinance within five years, you lose money on the points purchase. If you stay in the loan for ten or twenty years, the savings are substantial.
Mortgage points paid on a primary residence purchase are generally tax-deductible in the year paid for buyers who itemize deductions. This deductibility reduces the effective cost of points and improves their break-even timeline — worth factoring into the math if you itemize.
Running the break-even calculation
The break-even calculation for points is: point cost divided by monthly savings equals break-even months. On the example above, $4,000 divided by $66 equals roughly 61 months. If your realistic holding period for the loan is greater than 61 months, points are financially beneficial. If you expect to sell, pay off, or refinance within five years, skipping points preserves upfront cash that could be better deployed elsewhere. The median homeowner stays in their home for about 8–12 years, but median behavior doesn't predict your specific situation.
The opportunity cost of points
Cash paid for points at closing is cash that's not available for a down payment, emergency fund, or investment. If buying points means a smaller down payment, the calculation gets more complex — a smaller down payment may trigger PMI, which adds a monthly cost that competes against the monthly savings from the rate buydown. If buying points means a depleted emergency fund, the risk cost of that reduced financial cushion should factor into the decision. Cash at closing has alternative uses that should be part of the comparison.
- Calculate your specific break-even timeline before paying for points: point cost ÷ monthly savings = break-even months
- Assess your realistic probability of keeping this exact mortgage for longer than the break-even period
- Compare the rate of return on points against other uses of the same cash
- If you itemize taxes, factor in the deductibility of points in the year of purchase
Negative points: lender credits
The opposite of buying points is accepting lender credits — the lender pays some of your closing costs in exchange for a higher interest rate. This is useful when you're short on closing cost cash or plan to sell or refinance relatively soon, since the higher rate only costs you in the long run if you hold the loan for a long time. The same break-even logic applies: at what loan duration does the higher rate's cost exceed the closing cost credit received?
When points are most clearly worth considering
Paying points makes the most sense when: you're confident you'll hold the loan for significantly longer than the break-even period; you have sufficient cash that buying points doesn't create financial strain; and the rate environment suggests rates are likely to stay high (making a refinance in the near term unlikely, extending your expected holding period on this specific loan). Points are least attractive when you expect to sell within five years, when the points cost would strain your financial cushion, or when rate trends suggest a refinancing opportunity may emerge relatively soon.
Frequently asked questions
Can I finance mortgage points into the loan?
Points must generally be paid in cash at closing. You can't typically roll points into the loan balance, though some specific loan programs allow limited exceptions. A lender can clarify what's permitted in your specific situation.
Is it better to put more money down or buy points?
Generally, if you're below 20% down and paying PMI, eliminating PMI through a larger down payment produces a better financial return than buying points. Above 20% down, the comparison is more nuanced and depends on the specific rate reduction, break-even timeline, and alternative uses of the cash.
Can I negotiate how many points I pay?
Yes — the number of points is negotiable within the lender's pricing structure. You can choose to buy no points, a fraction of a point (0.5 points), one point, or more, each producing a different rate reduction. Some lenders allow fine-grained customization of this tradeoff at no-cost points or at any point count you choose.
What's the difference between origination points and discount points?
Discount points specifically purchase a rate reduction. Origination points are fees the lender charges for processing the loan — they don't buy a rate reduction. Both appear as "points" on a loan estimate but serve different functions. Confirm which type any quoted points represent before assuming a rate reduction is included.
