Should You Pay Mortgage Points? The Break-Even Arithmetic

What a discount point is and what it buys

A discount point is prepaid interest: a one-time fee of 1% of your loan amount, paid at closing, in exchange for a lower rate for the life of the loan. On a $400,000 loan, one point costs $4,000. What that point buys is the part people get wrong: there is no fixed exchange rate between points and rate. A common rule of thumb is about 0.25% off the rate per point, and that is the example Freddie Mac uses, but the CFPB is blunt that one lender''s point might buy a bigger or smaller reduction than another''s, and the same lender''s pricing changes day to day.

That means "should you pay points" is never answerable in the abstract. It is answerable with three numbers from your own quote: what the points cost, what the lower payment saves you each month, and how long you expect to keep the loan.

The break-even formula

Divide the cost of the points by the monthly savings, and you get the number of months until the points have paid for themselves. That is the entire formula. The CFPB describes it the same way: most borrowers only benefit from points if they keep the mortgage past this break-even period.

Cost of points ÷ monthly payment savings = break-even month.

Keep the loan longer than the break-even month and every month after it is profit. Refinance, sell, or pay the loan off before it, and you paid for a discount you never fully collected. Everything else in this article is just that formula with real numbers in it.

A worked example at $400,000

Take a $400,000 loan on a 30-year fixed. Your lender quotes 6.625% with zero points, or 6.375% if you pay one point ($4,000). Rates near this range are realistic as of early August 2026; Freddie Mac''s national survey put the average 30-year rate at 6.66% in late July.

At 6.625%, principal and interest run $2,561 a month. At 6.375%, they run $2,495. The point saves you $66 a month.

$4,000 ÷ $66 = about 61 months. Break-even is just past the five-year mark.

Now the decision is concrete. If this is a ten-year house, the point earns its keep: over the full 30 years the lower rate saves roughly $23,700 in interest, about $19,700 net of the $4,000 you paid. If there is a real chance you move or refinance within five years, the point is a coin flip at best. Sell at year three and you collected $66 a month for 36 months, about $2,370, on a $4,000 purchase: a $1,630 loss.

Two points work the same way, just doubled: $8,000 for 6.125% saves about $131 a month, and break-even still lands near month 61. Buying more points does not shorten the wait; it raises the stakes on the same bet.

One more comparison worth running: that same $4,000 put toward a bigger down payment instead shrinks the loan to $396,000 and saves only about $26 a month at 6.625%. Points beat down payment on monthly savings; down payment wins on flexibility, since the equity is yours no matter when you sell. Our mortgage points break-even calculator runs your own two quotes side by side and finds the break-even month.

What the arithmetic leaves out

The clean formula hides three real-world frictions, and all three push against paying points.

First, refinancing resets the clock. If rates fall enough that you refinance in year two or three, your old rate disappears and so does the discount you prepaid for. In a market where many buyers are told to "marry the house, date the rate," paying points while planning to refinance is paying twice for the same rate relief.

Second, the cash is gone from your closing table. Points are due at closing, on top of your down payment, other closing costs, and prepaids. On tight budgets, $4,000 in points is $4,000 not available for reserves, repairs, or the escrow cushion. If cash to close is already stretched, the points decision is really a reserves decision; our breakdown of cash to close versus down payment shows every line the points sit next to.

Third, the market evidence is not flattering. Freddie Mac research found the rate differential between comparable borrowers who paid points and those who did not was minor between 2018 and 2023, and concluded there is not a significant financial benefit to purchasing points for typical borrowers. At the same time, the CFPB found points became far more common as rates rose: 58.7% of home purchase borrowers paid some amount of points in the first three quarters of 2023, with a median of 1.0 point, and borrowers with lower credit scores paid them more often. Read those two findings together and the picture is uncomfortable: points are most often sold to the buyers least positioned to benefit, sometimes to bend a debt-to-income ratio enough to qualify. If a lender needs points to make your payment fit the approval box, that is worth noticing for its own sake.

Points on the Loan Estimate: how to compare quotes

Points live in Section A of page 2 of every Loan Estimate, so you can audit them line by line. The trap is comparing headline rates across lenders without noticing that one rate has points baked in and the other does not. The CFPB warns that advertised rates often include points in the fine print, which makes a lender look cheaper than it is.

The fix is to hold one variable still. Ask every lender for the same structure: same loan amount, same rate lock length, quoted at zero points. Then, separately, ask what one point buys at each shop. Two quotes at identical rates can differ by thousands in Section A, and two quotes with identical fees can differ in rate. This is the same discipline that makes rate shopping work at the pre-approval stage; our guide to pre-approval versus pre-qualification covers how to shop lenders inside the credit-inquiry window without hurting your score.

When someone else pays the points

Points do not have to be your money. Sellers and builders can pay them, and in a concession-friendly market they often offer to. The CFPB notes points can be paid by the seller or a third party such as a homebuilder, and lender rules treat seller-paid points as seller concessions, subject to the caps set by your loan type.

Seller-paid points change the break-even arithmetic completely: if the $4,000 is not your cash, there is no break-even month to wait out, and the $66 a month is simply yours. The real question becomes whether points were the best use of that seller credit compared with covering your closing costs or cutting the price. That comparison has its own arithmetic; our guide to concessions versus a price reduction walks through when a credit beats a cut.

The bottom line

Points are a purchase, not a feature. Price them like one. Get the same loan quoted with and without points, divide the cost by the monthly savings, and compare the break-even month to your honest timeline in the house, not your hoped-for one. Past the break-even, points quietly pay you every month for decades. Before it, they are a discount you funded and never used.
