Yes, you can buy discount points when refinancing a mortgage, and most major loan programs allow it. Each point costs 1% of your loan amount and typically shaves about 0.25 percentage points off your interest rate. Whether buying points on a refinance saves you money depends on how long you keep the new loan, whether the rate is fixed, and how the tax rules — which treat refinance points differently from purchase points — affect your break-even.
How a Point Works on a Refinance
A discount point is prepaid interest. You pay a lump sum at closing, and the lender lowers your rate for the life of the loan. One point on a $400,000 refinance costs $4,000. Two points cost $8,000 and might move an offered rate from 7.0% down to 6.5%. Fractional points are available too; half a point on that same loan runs $2,000.
The 0.25-point reduction per point is a rule of thumb, not a guarantee. Each lender’s pricing engine decides how much rate reduction a dollar of prepaid interest buys, and the ratios vary. What stays constant is the cost: one point always equals 1% of the loan amount.
On a fixed-rate refinance, the rate reduction is locked in for 15 or 30 years, and your savings are predictable every month. On an adjustable-rate mortgage, points only reduce the rate during the initial fixed period — three, five, or seven years, usually — before the loan resets. That short window makes points much harder to justify on an ARM.
Which Loan Programs Allow Points
Conventional loans backed by Fannie Mae and Freddie Mac let you buy points with no hard cap on the number. The practical ceiling comes from the lender’s pricing sheet, where additional points eventually stop producing meaningful rate reductions. On cash-out refinances, loan-level price adjustments based on loan-to-value and credit score can shrink the benefit of buying points.1Fannie Mae. Cash-Out Refinance Transactions
FHA loans allow discount points on both rate-and-term and streamline refinances, and the cost can be rolled into the new loan.2Department of Housing and Urban Development (HUD). Rate-and-Term Refinance FHA sets no specific numerical cap, but closing costs must stay reasonable and the loan still has to meet FHA’s loan-to-value limits after any financing of costs.
VA loans permit discount points, and third parties can pay for them on the borrower’s behalf. The standard is simply that points be “reasonable.” On a VA refinance (unlike a VA purchase), you can include the cost of points in the loan amount instead of bringing cash to closing.3Veterans Benefits Administration.

Calculating Your Break-Even Point
The break-even point is the number of months it takes for your monthly savings to equal what you paid upfront. The math is simple: divide the cost of the points by the monthly payment difference between the rate with points and the rate without.
Say one point costs $4,000 and lowers your monthly payment by $65. Divide $4,000 by $65 and you get roughly 62 months, or just over five years. Keep the loan longer than that and the points save you money. Sell or refinance earlier and you lost on the deal.
Both numbers come from your Loan Estimate. The point cost shows up in the origination charges section, and the lender should run the payment both ways on request.4Consumer Financial Protection Bureau. Loan Estimate Explainer A lender who won’t quote both scenarios side by side is a lender to walk away from.
The formula assumes you hold the loan to term, which rarely holds in real life. Job moves, family changes, and falling rates all push people to sell or refinance again before break-even. If you refinance before recouping the point cost, those savings disappear.5The Federal Reserve Board. A Consumer’s Guide to Mortgage Refinancings Rolling points into the loan balance stretches the break-even further, because now you’re paying interest on the money you borrowed to buy the rate reduction.
How Taxes Change the Math
Refinance points are taxed differently from purchase points, and this catches a lot of borrowers off guard. On a home purchase, you can generally deduct the full cost of points in the year you pay them. On a refinance, you cannot. You spread the deduction evenly over the life of the new loan.6Internal Revenue Service. Topic No. 504, Home Mortgage Points
On a 30-year refinance with $6,000 in points, that’s a $200 deduction each year, not a $6,000 deduction upfront. The smaller annual benefit stretches your effective break-even window beyond what the simple formula shows.
One exception helps. If part of the refinance proceeds pays for substantial improvements to your main home, the share of points tied to that improvement money can be deducted in full the year you pay. The rest still has to be spread over the loan term, and several other conditions apply.7Internal Revenue Service. Publication 936 (2025), Home Mortgage Interest Deduction
If you pay off the loan early, the unamortized point balance can usually be deducted in that final year. One trap: if you refinance again with the same lender, you don’t get the full deduction then. The leftover gets spread across the new loan’s term instead. Switching lenders avoids that.7Internal Revenue Service. Publication 936 (2025), Home Mortgage Interest Deduction
None of this matters if you take the standard deduction. Points produce a tax benefit only for itemizers.
Lender Credits: The Reverse Option
If paying thousands upfront doesn’t work for you, lender credits run the trade in reverse. You accept a higher interest rate, and the lender gives you cash to offset closing costs. Sometimes these are called negative points. The more credits you take, the higher the rate.8Consumer Financial Protection Bureau. How Should I Use Lender Credits and Points (Also Called Discount Points)?
Credits make sense when you expect to sell or refinance again within a few years, since you’d never hold the loan long enough for points to pay off. When shopping, ask every lender for three quotes: the rate with points, the rate without, and the rate with credits. That range shows the full menu.
The Legal Ceiling on Points
Federal law caps how much you can be charged in points and fees. For a loan to qualify as a Qualified Mortgage — the standard most lenders stick to — total points and fees must stay under 3% of the loan amount for loans of $137,958 or more in 2026. Smaller loans get slightly higher percentage caps, up to 8% for loans under $17,245.9Consumer Financial Protection Bureau. Truth in Lending (Regulation Z) Annual Threshold Adjustments (Credit Cards, HOEPA, and Qualified Mortgages)
That 3% figure is the practical ceiling on a typical refinance. And “points and fees” covers more than discount points: origination charges count too. If your lender charges a 1% origination fee, you have 2% left for discount points before bumping the cap. Above a separate, higher threshold, loans become classified as high-cost mortgages under HOEPA and most lenders simply refuse to make them.
When Buying Points Is Worth It
Points pay off when three things line up: you plan to keep the loan well past the break-even point, you’re refinancing into a fixed rate, and you have the cash available without draining emergency reserves. The sweet spot is borrowers staying put seven years or more and locking in a rate they feel no urgency to refinance away from.
Points are a weak choice on an ARM, because the lower rate only runs through the initial fixed period. They’re a bad bet if there’s any real chance you’ll move, refinance, or pay the loan off within the break-even window. And they produce no tax benefit if you take the standard deduction.
The common mistake is treating points as a default feature of refinancing rather than an optional investment. Get quotes with and without points from every lender you shop, run the break-even both ways, factor in the slower tax treatment, and base the decision on how long you’ll actually hold the loan — not how long you hope to.
