Mortgage points let you pay extra money at closing in exchange for a lower interest rate on your home loan. Whether you should buy mortgage points comes down to a simple trade: a known cost today against uncertain savings spread over many years. If you keep the loan long enough, the lower rate can more than repay the upfront fee. If you sell or refinance early, you may never earn that money back.
This guide explains how discount points work, how to calculate your break-even point, where points show up on your loan paperwork, how the tax rules treat them, and which situations tend to favor paying points versus skipping them. The examples use round, hypothetical numbers so you can follow the math and then plug in the figures from your own loan offers.
What Are Mortgage Points?
Mortgage points, also called discount points, are an optional fee you pay the lender at closing to “buy down” your interest rate. According to the Consumer Financial Protection Bureau (CFPB), one point equals 1% of the loan amount. On a $300,000 mortgage, one point costs $3,000.
Points do not have to be whole numbers. Lenders commonly price loans in fractions, so you might see offers with 0.5 points, 1.375 points, or 0.125 points. The cost is simply that fraction of your loan balance.
The key thing to understand is that a point has no fixed value in rate terms. The CFPB notes that how much your rate drops for each point depends on the lender, the type of loan, and market conditions. One lender may cut your rate by roughly a quarter of a percentage point per point, while another may offer a smaller or larger reduction for the same price. That is why you need to compare actual quotes rather than rely on a rule of thumb.
Lender credits: points in reverse
Lender credits work the opposite way. You accept a higher interest rate, and the lender gives you money to cover some of your closing costs. Lenders sometimes call these “negative points.” A credit can help if you are short on cash at closing, but you will pay more interest over time.
How to Calculate Your Break-Even Point
The single most useful number when deciding on points is the break-even period: how many months it takes for your monthly savings to add up to the upfront cost. The CFPB describes a rough estimate as the cost of the points divided by your monthly savings.
Here is a hypothetical example for a $300,000, 30-year fixed-rate loan. Assume the lender quotes 7.00% with no points, 6.75% with one point, and 6.50% with two points. Payments below are principal and interest only.
| Option | Upfront cost | Rate | Monthly P&I | Monthly savings | Break-even |
|---|---|---|---|---|---|
| No points | $0 | 7.00% | $1,995.91 | — | — |
| 1 point | $3,000 | 6.75% | $1,945.79 | $50.12 | About 60 months |
| 2 points | $6,000 | 6.50% | $1,896.20 | $99.71 | About 60 months |
In this example, either option takes about five years to break even. If you expect to stay in the home and keep the loan for 10 years, one point would save roughly $3,000 in payments beyond its cost ($50.12 × 120 months, minus $3,000). Over the full 30 years, the savings grow to around $15,000. But if you sell or refinance after three years, you would recover only about $1,800 of the $3,000 you paid, leaving you roughly $1,200 behind.
Real quotes rarely line up this neatly, so run the calculation for every option. The CFPB also suggests asking a loan officer to show total costs with and without points over the shortest, longest, and most likely time you expect to keep the loan.
When Buying Points Can Make Sense
- You plan to keep the loan for a long time. The longer you hold the mortgage past the break-even point, the more you save.
- You have cash left over after closing. Paying points should not drain your emergency fund or leave you unable to cover moving costs and repairs.
- You want the lowest possible monthly payment. A lower rate permanently reduces your principal and interest payment, which can help a tight budget.
- Rates are unlikely to fall enough for you to refinance soon. If you refinance, the points you paid on the old loan stop producing savings.
- The seller or builder is paying. The CFPB notes that points are sometimes paid by a home seller or a third party such as a builder. If you negotiate seller concessions, putting them toward points may be worth comparing against other closing costs.
When Skipping Points Is Usually Smarter
- You might move within a few years. Job changes, growing families, or relocation can cut your timeline short of break-even.
- You expect to refinance. If rates drop and you refinance, you effectively lose the remaining value of the points.
- Cash is tight. A larger cash cushion often matters more than a small rate reduction, especially in the first years of homeownership.
- You are unsure how long you will stay. The CFPB’s own guidance suggests that if you do not know how long you will keep the home or loan, you might not want to pay points.
Where Points Appear on Your Loan Documents
Discount points are listed on page 2, Section A (“Origination Charges”) of both your Loan Estimate and Closing Disclosure. Lender credits appear as a negative number in Section J on page 2. If you are new to these forms, our guide on how to read a Loan Estimate line by line walks through each section.
Points are part of your total closing costs, so they add to the cash you need on closing day. Our overview of closing costs when buying a home covers the other fees you should budget for.
How to Compare Offers With Different Points
Points make rate shopping harder. A lender advertising a low rate may be including points in the fine print. In its April 2024 research report, the CFPB warned that choosing a loan based only on the interest rate can lead borrowers to pay for more points than is best for their situation.
- Request quotes on the same day. Rates change daily, so same-day quotes make comparisons fair.
- Ask for the same number of points from each lender. The CFPB recommends this so you compare like with like, for example zero points from everyone, then one point from everyone.
- Compare the full Loan Estimate. Look at Section A and total closing costs, not just the headline rate.
- Calculate break-even for each option. Divide the cost of points by the monthly savings versus that lender’s zero-point rate.
- Consider rate type. You can buy points on fixed-rate and adjustable-rate loans, but on an adjustable-rate loan ask the lender how points affect the rate after the first adjustment. See our comparison of fixed-rate vs. adjustable-rate mortgages.
Points have become common. The same CFPB report, based on Home Mortgage Disclosure Act data, found that 58.7% of home purchase borrowers in the first three quarters of 2023 paid at least some discount points.
Are Mortgage Points Tax Deductible?
The IRS treats discount points as prepaid interest. If you itemize deductions on Schedule A, points may be deductible as home mortgage interest. Under IRS Tax Topic 504, you can generally deduct points in full in the year you pay them on a loan for your principal residence if all of these conditions are met, among others:
- The loan is used to buy, build, or improve your main home, and that home secures the loan.
- Paying points is an established practice in your area, and the amount is not more than what is generally charged there.
- You use the cash method of accounting (most individuals do).
- You provide funds at or before closing at least equal to the points. You cannot use money borrowed from the lender or broker to pay them.
- The points are calculated as a percentage of the loan principal and are clearly shown as points on your settlement statement.
Points that do not meet these tests, including points on a refinance or on a second home, are generally deducted gradually over the life of the loan. Points the seller pays on your behalf can be treated as paid by you, but you must subtract them from your home’s cost basis. Fees such as appraisal, notary, and mortgage note preparation charges are not deductible as interest.
Many households take the standard deduction instead of itemizing, in which case the deduction for points provides no extra benefit. Tax rules are detailed, so check IRS Publication 936 or consult a tax professional about your specific situation.
Frequently Asked Questions
How much does one mortgage point lower your rate?
There is no fixed amount. The rate reduction per point varies by lender, loan type, and market conditions. Always ask each lender for its specific rate at zero points and with each level of points it offers.
Can you roll points into your loan?
On a refinance, some lenders may let you roll closing costs, including points, into the new loan, within limits. However, financing points means paying interest on them, which lengthens your break-even period. For full first-year tax deductibility on a home purchase, the IRS requires that you provide funds at least equal to the points rather than borrowing them from the lender.
Are lender credits a bad deal?
Not necessarily. Credits trade a higher rate for lower upfront costs, which can make sense if you expect to move or refinance soon or need to preserve cash. You pay more over time, so the longer you keep the loan, the more a credit costs you.
Bottom Line
Buying mortgage points is a bet on time. Divide the cost of the points by the monthly savings to find your break-even point, then be honest about how long you are likely to keep the loan. If you plan to stay well beyond break-even and still have a healthy cash cushion after closing, points can lower your lifetime interest costs. If your plans are uncertain, cash is tight, or a refinance is likely, a zero-point loan or even lender credits may serve you better. Compare same-day quotes with the same number of points from several lenders before deciding.
