Mortgage points are one of the most misunderstood lines on a Loan Estimate. Some borrowers buy them automatically because a lower rate sounds smart. Others refuse them because they assume points are an upsell. Both groups are usually skipping the one step that actually answers the question: a simple break-even calculation.
This guide explains what points on a mortgage are, how they work, what they cost, how many you can buy, how they are treated at tax time, and how to decide whether they make sense for your loan. Our founders bring 60 years of combined mortgage experience and tens of thousands of closed loans, and the advice here is the same math we walk borrowers through before they sign anything.
What Are Points on a Mortgage?
A mortgage point, also called a discount point, is a fee you pay at closing in exchange for a lower interest rate for the life of the loan. You are essentially prepaying some interest up front so that you pay less interest every month afterward.
- One point costs 1% of the loan amount. On a $400,000 loan, one point is $4,000. Half a point is $2,000.
- Points are optional. You can almost always choose a loan with no discount points at a somewhat higher rate.
- Points are tied to the loan, not the house. If you sell or refinance, the rate you paid for goes away with the old loan.
How Mortgage Points Work
Lenders price every loan as a menu of rate and cost combinations. At one end, you pay points and get a lower rate. In the middle, you pay no points and take the standard rate. At the other end, you accept a higher rate and the lender gives you a credit toward closing costs.
How much one point lowers your rate is not fixed. It depends on the lender, the loan program, and what the bond market is doing that week. A point often lowers the rate by somewhere around an eighth to a quarter of a percentage point, but that is a rough range, not a rule. The same point that buys a meaningful reduction one month may barely move the rate a few months later. That is why the only numbers that matter are the ones on your actual Loan Estimate, not a rule of thumb you read online or remember from your last loan.
Discount Points vs. Origination Points
On the Loan Estimate, discount points show up in Section A, “Origination Charges,” as a percentage of the loan amount. That placement is why borrowers often confuse the two.
- Discount points are optional and buy you a lower rate. This is what people usually mean by “buying points.”
- Origination charges (sometimes quoted as origination points) are the lender’s fee for making the loan. They do not lower your rate.
Before you run any break-even math, make sure you are looking at the discount point line, not the lender’s origination fee.
The Break-Even Calculation: The Only Math That Matters
Divide the cost of the points by how much they save you each month. The answer is the number of months it takes for the lower payment to pay back what you spent at closing.
Break-even (months) = cost of points ÷ monthly savings
Hypothetical example: on a $400,000 loan, one point costs $4,000. If that point saves you $75 a month, $4,000 ÷ $75 is about 53 months, or roughly four and a half years. For those first 53 months you have not saved anything. You have only been paying yourself back. Real savings start after that, and only if you still have the loan.
Here is how the same idea plays out across a few illustrative scenarios:
| Cost of points | Monthly savings | Break-even | Worth considering if you keep the loan… |
| $4,000 | $110 | 36 months (3 years) | Well past 3 years |
| $4,000 | $65 | 62 months (about 5 years) | Well past 5 years |
| $7,000 | $100 | 70 months (about 6 years) | Well past 6 years |
| $10,000 | $100 | 100 months (about 8 years) | Rarely worth it |
All figures are hypothetical and for illustration only. Your costs and savings will depend on your loan amount, program, credit profile, and market pricing on the day you lock.
Look at the first two rows. Same $4,000 cost, but a bigger monthly savings cuts the break-even from five years to three. The price of the points is only half the story. What matters is how much rate reduction you actually get for that price.

Is It Worth Buying Points? It Depends on How Long You Keep the Loan
Once you know your break-even, there is only one more question: how long will you realistically keep this loan before you sell or refinance?
- Points usually make sense when the break-even is short (three to five years) and you are confident you will keep the loan well beyond it. A long-term home, a stable job, and no plans to refinance all point in this direction.
- Points usually do not make sense when you expect to sell or refinance within five to seven years, when the break-even is long, or when rates look likely to fall and a refinance is a real possibility. Any money spent on points is lost the day that loan is paid off.
Nobody can predict the future perfectly. Job moves, growing families, and rate drops change plans all the time. The goal is not certainty. It is being honest about your most likely scenario and letting that, not the lowest rate on paper, guide the decision.
How Many Points Can You Buy Down on a Mortgage?
There is no single universal limit, but there are practical ones.
- Lender limits: each lender sets how far it will let you buy down the rate, and the benefit of each extra point usually shrinks as you go.
- Federal points-and-fees limits: for most loan sizes, Qualified Mortgage rules cap total points and fees at 3% of the loan amount. Some bona fide discount points can be excluded from that count, so the real ceiling depends on the loan.
- Program rules: FHA, VA, conventional, and non-QM loans each have their own pricing and fee rules.
In practice, most borrowers who buy points buy somewhere between a fraction of a point and two points. Past that, the extra rate reduction rarely justifies the cost.
Are Mortgage Points Tax Deductible?
Often, but not always. Under current IRS rules (see IRS Publication 936), discount points are treated as prepaid mortgage interest.
- Buying your main home: points may be deductible in full in the year you pay them if you meet the IRS conditions, such as the points being computed as a percentage of the loan and clearly shown on your closing documents.
- Refinancing: points are generally deducted gradually over the life of the loan rather than all at once.
- You have to itemize: if you take the standard deduction, points do not lower your taxes.
Tax rules change and every situation is different, so talk to a tax professional before counting on a deduction. We can explain how points affect your loan, but we cannot give tax advice.
Lender Credits: Points in Reverse
Points can also work the other way. You can accept a slightly higher rate in exchange for a lender credit that covers part of your closing costs. This is sometimes called “negative points.”
The same break-even logic applies in reverse. You are trading a higher monthly payment for cash today. That can be a smart move if you are tight on funds to close, or if you are confident you will refinance or sell within a few years and will not keep the higher rate for long. It is worth asking about if keeping cash in the bank matters more to you than the lowest possible rate.
Points vs. a Temporary Buydown
Discount points permanently lower the rate for the life of the loan. A temporary buydown, like a 2-1 buydown, lowers the payment only for the first year or two, after which the loan returns to its full rate. Temporary buydowns are often funded by a seller or builder and suit buyers who expect their income to grow. We compare the two in our guide to mortgage buydowns.
Can the Seller Pay for Your Points?
Yes. In many deals, especially when a home has been sitting or a seller is motivated, you can negotiate seller concessions that cover part or all of your points. When someone else pays for the points, your break-even shortens dramatically, because your out-of-pocket cost drops while the monthly savings stay the same.
Seller contributions are capped by loan program. For example, FHA allows up to 6% of the purchase price, and conventional loans allow 3% to 9% depending on your down payment. In New Jersey, where property taxes and closing costs already put pressure on cash to close, asking for seller-paid points is often worth the conversation. Our guide to seller concessions explains how to ask and what the limits are.
Do Points Make Sense on an ARM or a Refinance?
Adjustable-rate mortgages: usually not. Most borrowers choose an ARM because they expect to sell or refinance before the fixed period ends, which means paying to permanently lower a rate they do not plan to keep.
Refinances: the same break-even test applies, with one extra risk. If rates drop again and you refinance a second time, the points you paid on this loan are gone. Be especially careful about buying points when rates are high and expected to come down.
Investment properties: points can improve cash flow on a long-term hold, but match the break-even to your actual holding period on this property, not your habit on the last one. Investors who sell or cash-out refinance every few years often come out ahead keeping the cash for the next down payment.
Better Uses for the Same Cash
Before you spend thousands on points, compare the alternatives:
- A larger down payment can lower your loan amount and, on a conventional loan, may reduce or remove private mortgage insurance. See our mortgage insurance explainer.
- Cash reserves for the repairs and surprises that tend to show up in the first year of owning a home.
- Covering closing costs so you do not need a lender credit and a higher rate. Our closing costs guide breaks down what to expect.
How to Decide in Five Steps
- Ask for a Loan Estimate with and without points, so you can see the real cost and the real monthly savings side by side.
- Divide the cost of the points by the monthly savings to get your break-even in months.
- Be honest about how long you are likely to keep this loan.
- If your timeline comfortably beats the break-even, points are worth serious consideration. If it is close or shorter, keep your cash.
- Ask whether seller concessions or lender credits could improve the math.
A good loan officer will show you this calculation in writing. If someone gives you a blanket “always buy points” or “never buy points” answer without running your numbers, that is worth noticing.
Frequently Asked Questions
What are points on a mortgage?
Mortgage points, or discount points, are an optional fee paid at closing to lower your interest rate for the life of the loan. One point costs 1% of the loan amount, so one point on a $300,000 loan is $3,000.
How much does one point lower your mortgage rate?
It varies by lender, loan program, and market conditions. One point often lowers the rate by roughly an eighth to a quarter of a percentage point, but the only reliable number is the one on your own Loan Estimate.
How many points can you buy down on a mortgage?
Lenders set their own limits, and for most loan sizes federal Qualified Mortgage rules cap total points and fees at 3% of the loan amount, with some discount points excluded. Most borrowers who buy points buy two or fewer, because each additional point tends to deliver less benefit.
Are mortgage points tax deductible?
Often, if you itemize. Points paid to buy your main home may be deductible in the year you pay them, while points on a refinance are generally deducted over the life of the loan. Check IRS Publication 936 and confirm with a tax professional.
Is it worth buying points on a mortgage?
It is worth it when your break-even period is short and you are confident you will keep the loan well past it. If you expect to sell or refinance within five to seven years, you will usually do better keeping the cash.
Can the seller pay for my mortgage points?
Yes. Seller concessions can cover discount points, subject to your loan program’s limits on seller contributions. Seller-paid points shorten your break-even because your out-of-pocket cost goes down.
