Mortgage Points Explained: Should You Buy Down Your Rate?

When you get a mortgage rate quote, your lender may offer you the option to pay money upfront in exchange for a lower interest rate for the life of the loan. These prepaid fees are called mortgage points — and deciding whether to buy them is one of the most consequential financial choices you will make at the closing table. The answer depends entirely on how long you plan to stay in the home.

What Are Mortgage Points?

A mortgage point is equal to 1% of the loan amount. On a $400,000 mortgage, one point costs $4,000. Points come in two distinct varieties that are easy to confuse:

Discount Points

Discount points are prepaid interest. You pay money at closing in exchange for a permanently lower interest rate on your loan. One discount point typically reduces your rate by 0.25%, though the exact reduction varies by lender, loan type, and market conditions. Paying two points might drop your rate from 7.00% to 6.50%. This is an optional choice — you are essentially pre-purchasing interest savings that will accrue over time.

Origination Points

Origination points are a lender fee for processing your loan, sometimes expressed as a percentage of the loan amount. Unlike discount points, origination points do not reduce your interest rate — they are simply compensation to the lender. Some lenders charge origination points; others charge a flat origination fee or roll the cost into a higher rate. Always read your Loan Estimate carefully to distinguish between the two. This article focuses on discount points, since those represent an active financial decision you can optimize.

How Discount Points Work in Practice

Here is a concrete illustration. Suppose you are borrowing $400,000 at a base rate of 7.00% for 30 years. Your base monthly payment (principal and interest) is approximately $2,661. Now suppose your lender offers you the following menu:

Each point costs $4,000 and saves you roughly $67 per month. The question is whether the upfront cost is worth the long-term savings. That depends on how long you keep the loan — which is exactly what the break-even calculation tells you.

Use our mortgage calculator to compare how different rates and loan amounts affect your monthly payment before deciding how many points to buy.

The Break-Even Calculation

The break-even point is the number of months it takes for your cumulative interest savings to equal the upfront cost of the points. The formula is straightforward:

Break-Even Months = Cost of Points ÷ Monthly Savings

Using the example above: paying one point costs $4,000 and saves $67 per month. Break-even = $4,000 ÷ $67 = approximately 60 months, or 5 years. If you stay in the home and keep the loan for more than 5 years, you come out ahead. If you sell or refinance before the 5-year mark, you will not have recouped the upfront cost.

Two points: $8,000 ÷ $133/month savings = 60 months as well, since the ratio stays constant when the lender's pricing is linear. In practice, the second point sometimes offers a slightly less efficient trade than the first — always calculate each increment separately.

For refinance scenarios where you are also evaluating closing costs against monthly savings, use our refinance break-even calculator to model the full picture.

Tax Deductibility of Points

Discount points paid on a mortgage used to purchase your primary residence are generally deductible as mortgage interest in the year they are paid, provided the loan meets certain IRS requirements. This can meaningfully improve the economics of buying points for borrowers who itemize deductions. If you pay $4,000 in points and are in the 24% tax bracket, your effective after-tax cost is closer to $3,040 — which shortens your break-even period noticeably.

Points paid on a refinance are not deductible all at once; they must be amortized and deducted ratably over the life of the loan. Consult a tax professional for guidance on your specific situation, as the rules have nuances around loan amounts, second homes, and investment properties.

When Buying Points Makes Sense

Points are a good deal in specific circumstances. Understanding the profile of a good candidate helps you decide quickly at the loan estimate stage rather than guessing.

You Plan to Stay Long-Term

If you are buying a home you expect to live in for 10 or more years — a starter home that will become a forever home, a property near family, or a home purchased in a stable job market — the break-even math strongly favors points. Every month past break-even is pure savings, compounding over years into thousands of dollars.

You Have Extra Cash at Closing

Points only make sense if buying them does not put a strain on your reserves. Depleting your emergency fund or retirement savings to buy down your rate is rarely wise. But if you have sufficient cash for the down payment and closing costs with funds left over, points can be an efficient place to put excess capital.

Rates Are High and You Are Not Likely to Refinance Soon

When rates are already elevated, paying points to lock in a lower rate protects you if rates rise further or remain high for years. If rates drop, you will likely refinance anyway — and when you do, you lose the remaining value of the points you paid. In a declining-rate environment, points are a riskier bet.

Qualifying DTI Is Tight

If your debt-to-income ratio is near the lender's maximum, a lower monthly payment achieved through points may make the difference between qualifying and being declined. In this case, the cost of the points is not just an investment decision — it is the price of getting the loan at all. Check our DTI calculator to see how a lower rate affects your qualification ratio.

When NOT to Buy Points

Points are often a bad deal in situations that many buyers fail to recognize at the time of purchase.

You Might Move or Refinance Within 5–7 Years

The U.S. median home tenure has hovered around 8–10 years, but that average masks the reality that many households move sooner — for job changes, growing families, or market opportunities. If there is a meaningful chance you will sell or refinance before break-even, you are handing money to the lender for savings you will never collect.

You Need the Cash for the Down Payment

A higher down payment directly reduces your loan balance, eliminates or reduces PMI, and lowers your LTV — all of which can save more money than points. In most cases, putting extra cash toward the down payment is a better use of funds than buying points. Use our PMI calculator to compare the cost of PMI against the cost of points and see which path is cheaper over your expected holding period.

The Lender's Pricing Is Inefficient

Not all points are created equal. Some lenders offer only 0.125% rate reduction per point instead of 0.25%, effectively doubling your break-even period. Always verify the exact rate reduction per point, calculate your specific break-even, and compare quotes from multiple lenders before buying points. A lender offering a lower base rate without points may be the better deal entirely.

Fractional Points and Negative Points

You do not have to buy points in whole increments. Lenders routinely offer pricing for 0.5 or even 0.25 points, letting you fine-tune the rate-cost trade-off. Conversely, lenders also offer "negative points" — sometimes called lender credits — where the lender pays some of your closing costs in exchange for a higher interest rate. This is the opposite of buying points: you get cash at closing but pay more each month. Lender credits can be a smart choice if you are short on cash at closing and plan to move or refinance within a few years.

The same break-even logic applies in reverse: calculate how many months of higher payments it takes to consume the credit you received. If you will sell or refinance before that point, lender credits are a net positive. If you stay longer, you will have paid more in total interest than the credit was worth.

How to Negotiate Points at Closing

Points are negotiable, and lenders expect borrowers to shop around. A few practical tips:

Get Loan Estimates from at least three lenders and compare them on the same loan amount and term. One lender's "no-points" rate may be lower than another lender's "one-point" rate. The Loan Estimate form, standardized by federal regulation, makes direct comparison straightforward — look at Section A (Origination Charges) and the interest rate to evaluate each offer on equal terms.

Ask your lender explicitly: "What is my rate with zero points? What is the rate with one point? What is the rate with two points?" Not all lenders proactively show you the full menu. Once you have the numbers, calculate your break-even for each option and make the decision that fits your timeline.

If you are buying in a high-rate environment and plan to refinance when rates fall, you can use our refinance calculator to model what your new payment would look like at various future rates — helping you decide whether paying points on today's loan or saving cash for future closing costs is the smarter strategy.

The Bottom Line

Mortgage points are a time-value-of-money decision dressed in loan pricing clothing. You are trading cash today for savings over time. The math is simple; the uncertainty is in predicting how long you will keep the loan. As a rule of thumb: if your break-even is under 5 years and you are confident you will stay, points are usually worth it. If your break-even is over 7 years or your plans are uncertain, keeping the cash and taking the higher rate is often the better call.

Before you close, run the numbers for your actual loan amount and lender's pricing. Our mortgage calculator lets you compare payments at different rates instantly, so you can make the points decision with real numbers rather than rules of thumb.
