When you start comparing mortgage offers, you will run into a curious option: for an extra payment at closing, the lender will lower your interest rate. That trade-off has a name — mortgage points, also called discount points — and it is one of the most misunderstood levers in the whole home-financing process. Buy points and your monthly payment shrinks, but your upfront cash-to-close grows. Skip them and you keep more cash today at the price of a slightly higher rate. Neither choice is automatically “right”; it all depends on your situation.
This guide breaks down exactly what discount points are, how paying them lowers your rate, and — most importantly — how to run the break-even calculation that tells you whether they are worth it. We will walk through an illustrative worked example step by step, cover when points make sense versus when they usually do not, clear up the difference between origination points and discount points, and explain lender credits (sometimes called negative points), which are essentially points in reverse. By the end you will be able to look at a rate sheet and know which column actually serves you.
What Are Mortgage Discount Points?
Discount points are an upfront fee you can choose to pay your lender at closing in exchange for a lower interest rate on your mortgage. In effect, you are pre-paying some interest to secure a cheaper rate over the life of the loan. This is sometimes described as “buying down” your rate, and it is entirely optional — a tool you can use, not a required cost.
The pricing follows a simple convention: one discount point costs 1% of your loan amount. So on a $300,000 loan, one point costs $3,000. You are not limited to whole points either — lenders often let you buy fractions, like half a point or a point and a half, and the cost scales accordingly. A half point on that same loan would cost $1,500.
What you get in return is a rate reduction. As a rough rule of thumb, one point often lowers your rate by roughly 0.25 percentage points — for example, from 6.75% down to 6.50% — though the exact reduction varies by lender, loan type, and current market conditions. Some lenders offer more reduction per point, some less, so you should never assume the 0.25% figure; always check the specific numbers on your loan estimate. Because points are part of your closing costs, buying them raises the cash you need on closing day.
How Buying Points Lowers Your Rate
The mechanic is straightforward: you hand over more money upfront, and in exchange the lender reduces the interest rate they charge you for the entire loan term. A lower rate means a lower monthly principal-and-interest payment, and it also means you pay less total interest over the years you hold the loan. The savings are small each month but they accumulate — which is exactly why the math depends so heavily on how long you keep the mortgage.
Think of it as a trade between now and later. You spend a lump sum today to buy a stream of monthly savings that stretches into the future. If you hold the loan long enough, the accumulated monthly savings eventually exceed what you paid upfront, and from that point on you are ahead. If you sell or refinance before that crossover point, you never recoup the cost, and buying points was a losing trade. That crossover moment is the whole game, and it has a name: the break-even point.
One more nuance worth knowing: discount points on a home purchase may be tax-deductible in some circumstances, since the IRS treats them as prepaid mortgage interest. The rules have conditions and limits, so this is a question for a tax professional rather than a reason to buy points on its own. Never let a potential deduction be the deciding factor — the break-even math should lead.
The Break-Even Calculation
The break-even point is the number of months it takes for your monthly savings to add up to the amount you paid for the points. It is the single most important number in this entire decision, and the formula is refreshingly simple:
- Break-even (months) = Cost of the points ÷ Monthly payment savings
Once you have that number, the logic is easy: if you expect to keep the loan (that is, stay in the home without refinancing) longer than the break-even period, buying points tends to pay off. If you expect to move or refinance before break-even, you would likely be better off keeping the cash. The comparison that matters is break-even months versus how long you realistically plan to hold this exact mortgage.
An Illustrative Worked Example
The following numbers are illustrative only — they are rounded, simplified figures meant to demonstrate the method, not real quotes. Your actual costs and savings will differ, so run the calculation with the specific numbers on your own loan estimate.
Imagine a $300,000, 30-year fixed-rate mortgage, and the lender offers this choice:
- Option A — no points: interest rate of 6.75%, with a monthly principal-and-interest payment of roughly $1,946.
- Option B — buy 1 point: pay $3,000 upfront (1% of $300,000) to lower the rate to 6.50%, with a monthly payment of roughly $1,896.
Now walk the math:
- Monthly savings: $1,946 − $1,896 = about $50 per month.
- Cost of the point: $3,000.
- Break-even: $3,000 ÷ $50 = 60 months, or 5 years.
So in this illustrative case, you would need to keep the loan for about five years just to recoup the $3,000. Stay in the home with this mortgage for ten or fifteen years and the point looks like a smart buy — you would save roughly $50 every month for years after break-even, adding up to real money. But if you suspect you will move or refinance within, say, three years, you would sell before ever breaking even, and that $3,000 would have been better kept in your pocket. Same numbers, opposite conclusion — the deciding factor is entirely your time horizon. A mortgage calculator makes it easy to test different rates and point amounts against your own budget.
When Buying Points Makes Sense
Points are not universally good or bad — they are a fit for certain situations and a poor choice for others. Buying discount points tends to make sense when several of the following are true:
- You plan to stay in the home for a long time. The longer you hold the loan past the break-even point, the more you save. If this is a long-term or “forever” home, points have room to pay off.
- You have plenty of cash beyond the essentials. Points make sense only if paying for them does not drain the reserves you need for your down payment, moving costs, an emergency fund, and early homeownership surprises.
- You are confident you will not refinance soon. Refinancing replaces the loan and resets the clock, so if rates might drop and you would refinance, the points on your original loan could be wasted.
- The rate reduction per point is generous. If a lender offers a bigger-than-typical rate cut per point, the break-even period shrinks and the deal improves.
In these scenarios, points let a well-capitalized buyer lock in lower payments for the long haul. If you are still figuring out how much cash you will have on hand, our guide on how much house you can afford can help you see whether spending on points leaves you comfortable or stretched.
When Points Usually Do Not Make Sense
Just as often, points are the wrong move. Here is when you should be skeptical of buying them:
- You might move within a few years. Starter homes, job-relocation risk, or growing families all raise the odds you will sell before break-even. If your expected stay is shorter than the break-even period, points lose money.
- Your cash is tight. If paying for points would shrink your down payment, wipe out your emergency fund, or leave you scrambling for closing costs, the upfront cost is simply too steep. Cash reserves usually matter more to a new homeowner than a slightly lower rate.
- You could put the money to better use. Sometimes that same lump sum does more good as a larger down payment (which can reduce or eliminate mortgage insurance), paying off high-interest debt, or staying invested. Points are just one option competing for your dollars.
- Rates may fall and you would refinance. If a refinance is plausible, you might replace the loan before the points ever pay for themselves.
The through-line in all of these is simple: points reward patience and punish short time horizons or thin cash cushions. When in doubt, protect your liquidity.

Origination Points vs. Discount Points
The word “points” gets used for two very different things on a mortgage, and confusing them can cost you. Both are quoted as a percentage of the loan amount, but they do opposite things for you.
Discount Points
Discount points are the optional buy-down fee this whole article is about. You choose to pay them, and in return you get a lower interest rate. They are a voluntary investment in cheaper monthly payments — a benefit you buy.
Origination Points
Origination points (part of what lenders call an origination fee or origination charge) are what the lender charges to process and underwrite your loan. Unlike discount points, they do not lower your rate — they are simply the cost of doing business with that lender. One origination point also equals 1% of the loan amount, which is why the naming is so easy to mix up.
The practical difference: discount points give you something back (a lower rate), while origination points are a fee you pay for the lender’s service. When comparing loan estimates, look carefully at both line items. A loan advertising a low rate might carry higher origination charges, and a loan with “points” listed could mean either type. Reading the loan estimate closely — and asking the lender to spell out which points are which — is essential to a true apples-to-apples comparison. Getting your financing squared away early, as covered in pre-approval versus pre-qualification, gives you time to scrutinize these details.
Lender Credits (Negative Points)
Points also work in reverse, and this option can be a lifesaver for cash-strapped buyers. Lender credits — sometimes called negative points — are the mirror image of discount points. Instead of paying money upfront to lower your rate, you accept a higher interest rate in exchange for the lender covering some of your closing costs. You are trading a bit more each month for less cash needed today.
The trade-off flips the break-even logic on its head. With lender credits, you save money at closing but pay more over time through the higher rate. That can be exactly the right move if:
- You are short on cash for closing and would rather keep your reserves intact.
- You expect to move or refinance relatively soon, so the higher rate would not follow you for long — the reverse of the case for buying discount points.
- You value liquidity now more than the long-run interest savings.
Think of the full menu as a spectrum. On one end, you pay discount points for a lower rate and higher upfront cost. In the middle, you take the lender’s “par” rate with no points either way. On the other end, you take lender credits for a higher rate and lower upfront cost. Where you land should reflect how much cash you have, how long you plan to keep the loan, and which matters more to you right now — smaller payments later or more money in the bank today. Whichever direction you lean, ask your lender to show you the same loan at several point levels so you can compare the numbers directly. Our first-time buyer guide puts this decision in the context of everything else happening at closing.
Frequently Asked Questions
What is a mortgage point worth?
One mortgage discount point costs 1% of your loan amount — for example, $3,000 on a $300,000 loan. In return, it typically lowers your interest rate by roughly 0.25 percentage points, though the exact reduction varies by lender, loan type, and market conditions. Always check the specific numbers on your loan estimate rather than assuming a fixed figure.
How do I calculate the break-even point on mortgage points?
Divide the total cost of the points by your monthly payment savings. For example, if one point costs $3,000 and it saves you $50 a month, your break-even is $3,000 ÷ $50 = 60 months, or five years. If you plan to keep the loan longer than the break-even period, buying points tends to pay off; if you will move or refinance sooner, it usually does not.
Are discount points worth it?
It depends on how long you keep the loan and how much cash you have. Points are worth it when you plan to stay in the home well past the break-even point and have plenty of cash beyond your down payment and reserves. They are usually not worth it if you might move or refinance soon, or if paying for them would strain your finances.
What is the difference between origination points and discount points?
Discount points are an optional fee you pay to lower your interest rate — a benefit you buy. Origination points are a charge the lender assesses to process and underwrite your loan, and they do not lower your rate. Both equal 1% of the loan amount each, so read your loan estimate carefully to see which type any listed points are.
What are lender credits or negative points?
Lender credits, sometimes called negative points, are the opposite of discount points. Instead of paying upfront to lower your rate, you accept a higher interest rate in exchange for the lender covering part of your closing costs. This can help if you are short on cash or expect to move or refinance soon, since you would not carry the higher rate for long.
Can I buy a fraction of a point?
Yes. Lenders often let you buy points in fractions, such as half a point or a point and a half, and the cost scales accordingly. A half point on a $300,000 loan would cost $1,500 and would lower your rate by a correspondingly smaller amount. This flexibility lets you fine-tune the trade-off between upfront cost and monthly savings.
Are mortgage points tax-deductible?
Discount points on a home purchase may be tax-deductible in some circumstances because the IRS can treat them as prepaid mortgage interest, but the rules have conditions and limits. Whether you qualify depends on your specific situation, so consult a tax professional. A potential deduction should never be the main reason to buy points — let the break-even math lead.
Is it better to buy points or make a bigger down payment?
It depends on your goals. A larger down payment can reduce your loan balance and may lower or eliminate mortgage insurance, while points lower your interest rate. If you have limited cash, protecting your reserves and reducing your loan balance often matters more than a slightly lower rate. Compare both options against your break-even timeline and your overall financial cushion.
