Yes, buying points on a refinance is allowed and works much the way it does on a purchase loan: you pay an upfront fee at closing and the lender gives you a lower interest rate for the life of the new mortgage. Whether it saves you money comes down to how long you keep the loan, how much the rate actually drops, and how you pay for the points.
What a Point Costs and What It Buys
One discount point equals one percent of the new loan amount. On a $300,000 refinance, one point is $3,000. In exchange, your interest rate drops. A common rule of thumb is roughly 0.25 percentage points off the rate for each point purchased, but the actual reduction depends on the lender, the loan type, and where rates sit when you lock.1Freddie Mac. What You Need to Know About Discount Points Get the exact numbers from your loan officer before you assume a fixed reduction.
You do not have to buy points in whole numbers. Most lenders will sell you fractional points, so half a point on that $300,000 loan would cost $1,500 and shave off a correspondingly smaller amount of interest. That flexibility lets you dial the upfront cost against the long-term savings.
Figuring the Break-Even
The break-even period is the single most useful number in this decision. Divide the total cost of the points by the monthly payment savings the lower rate produces. The result is how many months it takes to earn back what you spent.
Say two points on a $300,000 refinance cost $6,000 and the lower rate saves you $100 a month on principal and interest. Break-even is 60 months, or five years. Keep the loan longer than that and you come out ahead. Sell the home or refinance again sooner and you lose money on the trade.
The numbers you need are on your Loan Estimate. Points appear on page 2 in Section A; the principal-and-interest payment appears on page 1. Ask your loan officer to issue two Loan Estimates, one with points and one without, and compare them side by side.2Consumer Financial Protection Bureau. How Should I Use Lender Credits and Points (Also Called Discount Points)?
Both the Loan Estimate and the Closing Disclosure also carry a figure called the Total Interest Percentage, which expresses total interest over the full loan term as a percentage of the amount borrowed.3Consumer Financial Protection Bureau. Content of Disclosures for Certain Mortgage Transactions (Regulation Z 1026.37) Comparing this percentage across the two Loan Estimates shows the full lifetime impact of the points, not just the monthly change.
Paying Cash or Rolling the Points Into the Loan
You can pay for points at closing with a wire or certified check, or many lenders will let you finance them into the new loan balance. The choice changes the math.
Paying cash keeps your principal lower, so you get the full benefit of the lower rate. Rolling the cost into the loan spares you the immediate out-of-pocket hit, but the higher balance generates additional interest that eats into the savings the lower rate was supposed to produce. Run the break-even both ways before deciding.
Whether you can finance the points at all depends on the loan. Federal regulations specifically permit financing discount points into a VA Interest Rate Reduction Refinance Loan.4eCFR. 38 CFR 36.4312 – Interest Rates On conventional and FHA loans, it depends on the lender’s policy and whether the resulting loan-to-value ratio stays inside their limits.
Government-Backed Refinances: What’s Different
On a VA IRRRL, discount points can be financed into the loan balance, which is not the case on most other VA loan types where the borrower has to pay them out of pocket.4eCFR. 38 CFR 36.4312 – Interest Rates Federal rules do not set a specific numerical cap on the number of points a veteran can buy on an IRRRL, but the loan still has to satisfy VA net tangible benefit requirements.
FHA Streamline Refinances are the boundary case worth knowing. HUD policy generally prohibits discount points and interest rate buydowns on the streamline program. A standard FHA rate-and-term refinance is a different product and may permit points, so confirm which FHA refinance you are pursuing and check the current FHA handbook with your lender.
How the IRS Treats Refinance Points
Points on a refinance are treated differently from points on a purchase. In most cases you cannot deduct the full cost the year you pay it. Instead, you deduct the points evenly across the life of the new loan, so on a 30-year refinance you deduct one-thirtieth of the total each year.5Internal Revenue Service. Publication 936, Home Mortgage Interest Deduction
There is one exception. If you use part of the refinance proceeds to substantially improve your main home, the portion of the points tied to that improvement can be deducted in full the year you pay them, provided you paid with your own funds and meet the other IRS conditions for upfront deduction. The rest still gets spread across the loan term.6Internal Revenue Service. Topic No. 504, Home Mortgage Points
Refinancing again before the loan term ends changes the picture for any points you have not yet deducted. If the new loan is with a different lender, you can deduct the entire remaining balance of unamortized points in the year the old loan ends. If you refinance with the same lender, that lump-sum deduction is not allowed; the remaining balance gets added to any new points and spread across the new loan term.5Internal Revenue Service. Publication 936, Home Mortgage Interest Deduction
Lender Credits If You Would Rather Cut Closing Costs
Lender credits are the mirror image of points. The lender covers some or all of your closing costs and you accept a higher interest rate in return. On lender worksheets they sometimes appear as “negative points.”2Consumer Financial Protection Bureau. How Should I Use Lender Credits and Points (Also Called Discount Points)?
This works in your favor when your time horizon is short. If you plan to sell or refinance again in a few years, the higher rate does limited damage and the closing-cost savings stay in your pocket. Over a long hold, the extra interest adds up. Ask your loan officer to run Loan Estimates three ways: with points, without points, and with lender credits. Compare all three against how long you actually expect to keep the loan.
Federal Caps on Total Points and Fees
Federal law limits how much a lender can charge in total points and fees before a loan loses its status as a qualified mortgage. Those caps cover origination charges, certain third-party fees, and mortgage insurance premiums rolled into the loan, along with discount points. For a refinance of $137,958 or more in 2026, total points and fees cannot exceed 3 percent of the loan amount.7Consumer Financial Protection Bureau. Truth in Lending (Regulation Z) Annual Threshold Adjustments (Credit Cards, HOEPA, and Qualified Mortgages) Because that 3 percent is a combined cap, the room left for discount points is whatever is left after origination charges and other fees are accounted for. On smaller loan amounts, the cap is expressed as either a higher percentage or a fixed dollar figure.
Individual lenders layer their own eligibility rules on top: minimum credit score, loan-to-value limits, and debt-to-income requirements that show you can cover both the upfront point cost and the ongoing payment. Cash-out refinances usually face tighter underwriting than rate-and-term refinances. Because these standards vary, shopping more than one lender can turn up meaningfully different pricing on the same number of points.
Confirm the Prepayment Terms Before You Sign
Points only pay off if you keep the loan long enough to pass break-even, so a prepayment penalty would work directly against you. Under federal law, a qualified mortgage cannot impose a prepayment penalty after the first three years of the loan, and the penalty during those three years is capped on a declining scale.8Office of the Law Revision Counsel. 15 USC 1639c – Minimum Standards for Residential Mortgage Loans Most refinance loans today are structured as qualified mortgages, so prepayment penalties are either absent or narrowly limited. Confirm this on your Closing Disclosure before signing; the document states whether a prepayment penalty applies.
