When you shop for a mortgage, you will often see two rates side by side: one with points and one without. Mortgage points let you pay money upfront in exchange for a lower interest rate over the life of the loan. Whether that trade is worth it depends on how long you keep the loan and what you do with the cash you would otherwise spend. This article explains what points are, how the math works, and how to decide.

What Are Mortgage Points?

A mortgage point equals 1 percent of your loan amount. On a $300,000 loan, one point costs $3,000. There are two distinct kinds, and it is important not to confuse them.

Discount points are prepaid interest. You pay them at closing to “buy down” your interest rate. According to the Consumer Financial Protection Bureau, each discount point typically lowers your rate by a fraction of a percentage point, though the exact reduction varies by lender and market conditions. Discount points are optional.

Origination points are not a rate reduction. They are a fee the lender charges to process and underwrite the loan. Origination points are part of your cost of borrowing and show up on your Loan Estimate as origination charges. When people talk about “buying points to lower the rate,” they mean discount points.

Why Points Matter: Rate Versus APR

To compare loans fairly, look at both the interest rate and the annual percentage rate (APR). The interest rate determines your monthly payment. The APR is a broader figure that folds in points and certain fees, so it reflects the true yearly cost of the loan. Two loans can have the same interest rate but different APRs if one charges points and the other does not.

When you buy discount points, you lower the interest rate, which usually lowers the APR as well, but only because you paid cash upfront. The Consumer Financial Protection Bureau recommends comparing the Loan Estimates from several lenders, looking at the rate, the points, and the APR together rather than any single number in isolation.

How the Break-Even Math Works

Buying points only pays off if you keep the loan long enough to recover the upfront cost through lower monthly payments. The calculation mirrors a refinance break-even.

Imagine a $300,000 loan. Paying two points costs $6,000 and lowers your monthly payment by $90.

Break-even (in months) = Upfront cost / Monthly savings = 6,000 / 90 = about 67 months

That is roughly five and a half years. If you keep the loan longer than that, the points save you money. If you sell or refinance before then, you lose money on the points. This is why points tend to favor borrowers who plan to stay in the home and keep the same loan for a long time.

When Buying Points Can Make Sense

  • You plan to stay in the home for many years. The longer you hold the loan past the break-even point, the more you save.
  • You have cash beyond your down payment and emergency fund. Spending money on points should never drain the reserves you need for closing costs, moving, and unexpected expenses.
  • You want a lower fixed payment for budgeting reasons. A permanently lower rate can give long-term payment stability.

When Buying Points Usually Does Not

  • You might sell or refinance soon. If you will not reach the break-even point, points cost more than they save.
  • You are short on cash. Money is often better kept as reserves or applied to a larger down payment, which can reduce or remove PMI.
  • You could invest the cash for a higher return. Compare the guaranteed “return” from buying points against other uses of the same money.

A Note on Taxes

Discount points are prepaid interest, and in some cases they may be tax deductible. The rules depend on whether the loan is for a purchase or a refinance and how the points are paid. The Internal Revenue Service sets specific conditions for when points are deductible in the year paid versus spread over the life of the loan. This is a tax question with personal variables, so confirm your situation with a licensed tax professional rather than assuming a deduction.

Locking It In

If you decide to buy points, the rate and the points are tied together in your rate lock. A rate lock holds the quoted rate and point structure for a set window (often 30 to 60 days) while the loan is processed. Confirm in writing how many points you are paying and the exact rate they buy, and check that the final Closing Disclosure matches the Loan Estimate.

Conclusion

Mortgage points are a straightforward trade: cash now for a lower rate later. Discount points buy down your interest rate, while origination points are simply a lender fee. The decision comes down to the break-even calculation and how long you will keep the loan. If you will hold the mortgage well past the break-even point and have cash to spare after your reserves, points can lower your long-term cost. If your timeline is short or your cash is tight, skipping points is often the smarter move.

Before paying for points, request Loan Estimates from several lenders, run the break-even math, and discuss your timeline with a licensed loan officer.
