Mortgage Points Explained: Should You Buy Down Your Rate?

Mortgage Guides · Updated for 2026 · About an 8-minute read

When you compare loan offers, you'll often see a line item called "points." Paying points — also known as buying down your rate — lets you trade cash at closing for a lower interest rate over the life of the loan. Done right, it can save real money. Done without the math, it can tie up thousands of dollars you never recoup. This guide explains what points are, how to run the break-even calculation, and when a buydown actually makes sense in 2026.

What Are Mortgage Points?

A mortgage discount point is a fee you pay the lender up front, at closing, in exchange for a lower interest rate. One point equals 1% of your loan amount. On a $300,000 loan, one point costs $3,000. In return, the lender lowers your rate by a set amount — commonly somewhere around 0.25% per point, though the exact reduction varies by lender and market conditions.

Points are optional and separate from your down payment. You can often buy fractions of a point, and some buyers purchase two or more. It's also worth not confusing discount points with origination points, which are a lender fee for processing the loan rather than a rate buydown. This guide is about discount points — the kind that actually lower your rate.

The Break-Even Math

The whole decision comes down to one question: how long until the monthly savings pay back the up-front cost? That's your break-even point, and the formula is simple:

Break-even (months) = Cost of points ÷ Monthly payment savings

Work through an example. Say you're borrowing $300,000 on a 30-year loan. One point costs $3,000 and lowers your rate by 0.25%. Suppose that drops your monthly principal-and-interest payment by about $45. Divide $3,000 by $45 and you get roughly 67 months — about five and a half years — to break even. Stay in the loan past that point and the buydown is saving you money; leave before it, and you paid more than you got back.

When Buying Points Makes Sense

Points reward patience. The longer you keep the exact loan, the more the lower rate works in your favor. A buydown tends to make sense when:

• You plan to stay put for a long time. If you'll comfortably outlast the break-even period — often five to seven years or more — the ongoing savings can add up to real money.
• Rates are relatively high. When starting rates are elevated, buying them down can meaningfully cut your monthly cost.
• You have cash to spare after reserves. Paying points shouldn't drain the emergency fund you'll want as a new homeowner.
• You're confident you won't refinance soon. A future refinance resets the clock and can erase the benefit before you break even.

When to Skip the Buydown

Just as often, keeping your cash is the smarter play. Skipping points usually makes sense when you might sell or move within a few years, when you expect to refinance if rates fall, or when the money would be better spent lowering your loan balance or preserving reserves. Remember that a refinance or a sale before your break-even date means you never recoup the up-front cost.

There's also an opportunity-cost angle. The thousands you'd spend on points could instead go toward a larger down payment — which shrinks the loan and may help you avoid or reduce mortgage insurance. Our down payment guide walks through that trade-off. In some markets, using that cash for seller-paid closing costs or simply holding it as savings beats a buydown you may not keep long enough to benefit from.

Run the Numbers Before You Commit

Never buy points on vibes — always run the break-even. Ask each lender exactly how much a point costs and precisely how much it lowers your rate and monthly payment, because those figures differ from lender to lender. Then divide the cost by the monthly savings to see your break-even in months, and compare that honestly against how long you expect to keep the loan.

Our free mortgage payment calculator makes this easy: run your payment at the base rate, then again at the bought-down rate, and the difference is your monthly savings. Divide the point cost by that number and you've got your answer. A few minutes of math here can protect thousands of dollars at the closing table.
