A mortgage point is a fee equal to 1% of your loan amount that you pay at closing to lower your interest rate. On a $300,000 loan, one point costs $3,000, and in exchange the lender typically cuts your rate by about a quarter of a percentage point. Whether that trade is worth it is pure math: divide the cost of the points by the monthly savings they produce to find the break-even, and buy points only if you expect to keep the loan longer than that. This page walks through the mechanics, the break-even calculation, the tax treatment, and the FIRE-flavored question of whether the money is better spent elsewhere.
What Are Points on a Mortgage?
"Points" is shorthand for discount points, prepaid interest you hand the lender at closing in exchange for a lower rate on the loan. The term comes from the rate grid lenders use: each point on the grid lowers the rate a notch.
Two kinds of fees get called "points," and confusing them is expensive:
| Type | What it is | Tax treatment |
|---|---|---|
| Discount points | Prepaid interest that buys a lower rate | Deductible as mortgage interest, usually in full in the year of a purchase |
| Origination points | A lender fee for making the loan | Generally deductible as interest when tied to the loan |
When someone asks "what are points on a mortgage," they mean discount points: pay money now, get a lower payment for the life of the loan. Origination points are a separate fee for the privilege of borrowing, and they do not buy you a lower rate.
How Buying Points Lowers Your Rate
The mechanics are a straight trade. The lender shows you a rate grid, and each point you buy drops the rate by a set amount, commonly about a quarter of a point per point bought, though the exact amount varies by lender and market. Run the grid on a $300,000, 30-year fixed mortgage:
| Points bought | Upfront cost | Interest rate | Monthly payment |
|---|---|---|---|
| 0 | $0 | 6.50% | $1,896 |
| 1 | $3,000 | 6.25% | $1,847 |
| 2 | $6,000 | 6.00% | $1,799 |
So one point saves $49 a month, and two points save $97 a month. The savings are real but modest, and they cost you thousands upfront. Whether the deal is good depends entirely on how long you keep the loan, which brings us to the only number that matters.
The Break-Even Calculation
The break-even is the moment when the accumulated monthly savings finally cover the upfront cost of the points.
Break-even in months = Cost of points ÷ Monthly savings
Using the grid above: one point costs $3,000 and saves $49 a month, so the break-even is $3,000 divided by $49, which is about 61 months, or just over five years. Two points cost $6,000 and save $97 a month, for a nearly identical break-even of about 62 months.
That single number decides the question. If you will keep the mortgage longer than the break-even, points save you money. If you will sell or refinance before it, points lose you money. Lenders are required to hand you a Loan Estimate that shows the rate with and without points, so the inputs are right there on paper. Run the math at every point tier they offer and take the one where your expected ownership clears the break-even.
The honest tension for most buyers: the median time people stay in a home is well under the break-even on this example, which is why the default advice for short-horizon buyers is to skip points entirely.
When Points Make Sense
Points are a good deal when the numbers line up, and a bad deal when they do not.
Buy points when:
- You expect to keep the home well past the break-even. Seven-plus years on a 61-month break-even leaves years of pure savings.
- The cash does not hurt your down payment or emergency fund. Never buy points with money you need for closing, moving, or a rainy day.
- You are refinancing into a rate you will hold a long time. The math is identical; only the horizon changes.
Skip points when:
- You might move or refinance within five years. The break-even never arrives, and you have donated money to the lender.
- You are cash-strapped. Every dollar in points is a dollar unavailable for furniture, repairs, or your buffer.
- Better uses for the cash exist. The money's alternative is investing it, paying down other debt, or keeping liquidity, and any of those can beat a fixed, slow-building return.
Are Mortgage Points Tax Deductible?
Yes, with an important difference between purchases and refinances. Discount points are prepaid mortgage interest, so the IRS treats them as interest. On a purchase of a primary residence, you can generally deduct the full amount of the points in the year you pay them, as long as the points are expressed as a percentage of the loan, the practice is standard in your area, and the amount is not inflated. On a refinance, points generally have to be deducted a little each year over the life of the loan, because the refinance does not count as new acquisition money.
Two practical notes. First, to benefit from the deduction at all, your itemized deductions have to exceed the standard deduction, which in 2026 is $15,000 for single filers and $30,000 for married couples filing jointly, and itemizing means trading away that automatic deduction. With the $10,000 cap on state and local tax deductions and the interest deduction capped at mortgage debt of $750,000, a point deduction only matters if your itemized total clears the standard deduction. Second, you need a Closing Disclosure showing the points you paid, and on a refinance you will keep deducting a fraction each year for the life of the loan. The IRS's rules on home mortgage interest are the authoritative reference.
Mortgage Points vs Investing
For an investing audience, points are interesting because they are a guaranteed return, but only over the right horizon. Spending $3,000 to save $49 a month is a guaranteed 19.6% annualized return on the money if the loan runs the full 30 years. Over just five years it is a money-loser. Compare that with the same $3,000 in a diversified stock portfolio, which has historically compounded at a much higher long-run average with no break-even requirement, just volatility.
The framework is identical to the decision about paying down a mortgage early at all, and our pay off mortgage fast guide covers that version in depth. The short version for points: they act like a bond, a fixed, predictable, but modest return that only pays off if you stay put. Someone who values certainty and knows they will live in the house for a decade can reasonably buy points. Someone who wants liquidity, market growth, and the flexibility to move should skip them and invest the $3,000 instead. The mortgage vs invest calculator runs both futures side by side.
Points vs a Bigger Down Payment
Buying points and increasing your down payment are both ways to spend extra cash at closing, but they buy different things. A bigger down payment lowers your loan balance and your monthly payment for the life of the loan, and pushing past 20% down removes the need for private mortgage insurance. Points buy a lower rate on the same balance.
The decision rule: if you are sitting at 15% down, the first dollars are better spent reaching 20% and killing PMI, because PMI is a monthly premium you get nothing for. Once you are past the PMI threshold, compare a larger down payment against points on the same balance. A $3,000 larger down payment on a $300,000 loan at 6.5% cuts the payment by the interest on $3,000, about $19 a month and roughly $3,800 in interest over 30 years. The same $3,000 in points cuts the payment by $49 a month. Points win the monthly savings contest, but the down payment never has a break-even, because the interest saving starts on day one with zero risk of being lost to an early sale.
The catch is the same one you have already read: a bigger down payment cannot be lost, while points evaporate if you sell early. For a buyer who expects a long stay, points are the better use of the money. For a buyer with any chance of moving inside five years, the extra down payment is the safer and often smarter choice.
Common Mistakes With Mortgage Points
- Buying points without running the break-even. The loan estimate gives you the exact numbers. If you have not divided the cost by the savings, you are guessing.
- Buying points with money that should be the down payment or buffer. Points that force you to pay PMI or raid your emergency fund cost more than they save.
- Forgetting the refinance math changes. Points on a refinance have the same break-even rule but the deductibility is spread over the loan life, and the horizon is often short.
- Assuming every point lowers the rate the same amount. The rate reduction per point is set by the lender and can vary. Read the grid, not the marketing.
- Treating origination points as a tax deduction without checking. Origination points and discount points are both called "points" but they are treated differently on a purchase versus a refinance, and neither helps you if you take the standard deduction.
FAQ
What are points on a mortgage? Points, specifically discount points, are prepaid interest you pay at closing to lower your rate. One point equals 1% of your loan amount.
How much does one point lower a mortgage rate? Commonly about a quarter of a percentage point, though lenders set the exact amount and it varies by market and loan program.
How long does it take to break even on mortgage points? Divide the cost of the points by the monthly savings. At $3,000 for a $49 monthly saving, the break-even is about 61 months, just over five years.
Are mortgage points worth it? Only if you expect to keep the loan past the break-even. Short-horizon buyers usually lose money on points.
Can you deduct mortgage points? Yes, usually in full in the year you buy on a primary residence, and ratably over the loan on a refinance, provided your itemized deductions beat the standard deduction.
What is the difference between discount points and origination points? Discount points buy a lower rate. Origination points are a lender fee for making the loan. Both are often deductible as interest, but they do different jobs.
The Bottom Line
What are points on a mortgage? They are upfront fees, 1% of the loan per point, that buy a lower interest rate, commonly about a quarter point each. Whether they are worth it is a single calculation: divide the cost by the monthly savings to find the break-even, and buy points only if you expect to hold the loan past that date. They are tax-deductible as prepaid interest, subject to the standard deduction and the caps, and for the investment-minded they are a bond-like guaranteed return that only wins over long horizons. Before you sign anything, get the rate grid, run the break-even at every tier, and use the mortgage calculator hub to model the payments. Decide with the spreadsheet, not the lender's pitch.
