When you compare mortgage offers, you will often see rates quoted with points. Paying points can lower your interest rate for the life of the loan, but it costs cash up front that you might otherwise use for a larger down payment, reserves, or moving expenses. Whether mortgage discount points are worth it depends mostly on how long you will keep the loan. This guide explains how points work, how to run the numbers, and the alternatives.
What Are Mortgage Discount Points?
Discount points are prepaid interest you pay at closing in exchange for a lower interest rate. One point costs 1% of the loan amount. On a $400,000 loan, one point costs $4,000, half a point costs $2,000, and so on. Lenders also price in fractions, such as 0.375 or 0.125 points.
How much each point lowers your rate is not fixed. It depends on the lender, the loan program, and market conditions. As a rough guide, one point often reduces the rate by somewhere around 0.25 percentage point, but the actual reduction can be larger or smaller. Always ask for a rate sheet showing several options side by side.
Discount Points vs Origination Points
Origination points are fees for processing the loan, not for lowering the rate. Some lenders express origination charges as points, which can be confusing. On your Loan Estimate, discount points appear in Section A as a separate line item labeled with a percentage of the loan amount. Ask your lender to clarify any charge called a point.
How to Calculate the Break-Even Period
The key question is how long it takes for your monthly savings to repay the upfront cost.
Break-even (months) = Cost of points รท Monthly payment savings
Example
Suppose you are borrowing $400,000 on a 30-year fixed loan. A lender offers:
| Option | Points | Upfront cost | Monthly principal and interest (illustrative) |
|---|---|---|---|
| A | 0 | $0 | $2,661 |
| B | 1 | $4,000 | $2,594 |
Monthly savings with Option B are about $67. Dividing $4,000 by $67 gives a break-even of roughly 60 months, or five years. If you expect to keep the loan longer than five years, the points save money. If you might sell or refinance sooner, you would lose money on them.
The figures above are illustrative. Use your own Loan Estimates for real decisions.
A More Precise View
The simple formula ignores the return you could earn on the cash if you did not spend it on points, and it ignores that part of each payment reduces principal. For most homebuyers, though, the simple break-even is a reasonable guide. If the result is close to your expected holding period, err on the side of keeping your cash.
When Buying Points Makes Sense
- You plan to stay in the home and keep the loan for many years
- Rates are relatively low, so refinancing later is less likely
- You have enough cash for the down payment, closing costs, and a healthy emergency fund
- The seller is offering concessions that can be applied to points
When Points Are Usually Not Worth It
- You expect to move within a few years
- Rates are high and you anticipate refinancing if they fall
- Paying points would drain your reserves
- A larger down payment would help you avoid PMI or qualify for a better rate tier
Points vs a Larger Down Payment
If you have extra cash, you could buy points or increase your down payment. A larger down payment reduces the loan balance and can eliminate private mortgage insurance if it gets you to 20%. That benefit can outweigh a small rate reduction. If you are already putting 20% or more down, points may offer a better return. Run both scenarios with your lender.
Lender Credits: Negative Points
Lender credits work in reverse. You accept a higher interest rate, and the lender gives you a credit toward closing costs. This lowers your cash needed at closing but raises your monthly payment and total interest. Lender credits make sense if you are cash-constrained or expect to sell or refinance within a few years.
Temporary Buydowns
A temporary buydown, such as a 2-1 buydown, lowers your rate for the first one to three years only. For example, the rate might be two points lower in year one and one point lower in year two before returning to the note rate. The cost is usually paid upfront, often by the seller or builder as a concession. Temporary buydowns provide short-term relief but do not lower the long-term rate, and lenders typically qualify you at the full note rate.
Tax Treatment of Points
For a mortgage used to buy or build your main home, points may be fully deductible in the year paid if certain IRS conditions are met and you itemize deductions. Points paid on a refinance are generally deducted over the life of the loan instead. Seller-paid points may also be deductible by the buyer, which reduces the home’s cost basis. Because most households now take the standard deduction, the tax benefit may be small or nonexistent for you. Check IRS Publication 936 or ask a tax professional.
How to Shop for Points
- Ask each lender for a quote at zero points and at one point on the same day.
- Compare the rate reduction per point between lenders.
- Calculate the break-even period for each option.
- Consider your plans for the home and the likelihood of refinancing.
- Confirm points appear correctly in Section A of your Loan Estimate.
- Lock your rate and points together so pricing does not change.
Questions to Ask Your Lender
- How much does each point lower my rate on this loan?
- Can I buy fractional points?
- Are any of these charges origination points rather than discount points?
- Can seller concessions be used toward points?
- What would my rate be with lender credits instead?
Why Pricing Differs Between Lenders
Lenders set their own rate sheets based on investor pricing, their cost of funds, and how much business they want. One lender may lower your rate significantly for a single point, while another offers only a small reduction. That is why comparing several Loan Estimates on the same day matters so much. The best value is not always the lender with the lowest advertised rate, since that rate may already include points you would have to pay.
A Note on Advertised Rates
Mortgage ads often display a low rate that assumes the borrower pays points and has excellent credit, a large down payment, and a single-family primary residence. The fine print usually reveals the number of points assumed. Look at the APR, which includes points and certain fees, to see the fuller cost. Comparing APRs across offers with similar points helps cut through marketing.
Points on Government-Backed Loans
FHA, VA, and USDA loans also allow discount points. VA rules limit certain fees veterans can be charged, but reasonable discount points are permitted and can be paid by the seller. On FHA loans, points count toward the 6% seller contribution limit if the seller pays them. Because government loans often already carry competitive rates, the extra reduction from points may be small, so the break-even calculation is especially important. Ask your lender to show the exact pricing for your program rather than relying on general rules of thumb.
Frequently Asked Questions
How much does one mortgage point cost?
One point costs 1% of your loan amount. On a $300,000 loan, one point is $3,000.
How much does a point lower my rate?
It varies by lender and market. A common range is roughly 0.125 to 0.25 percentage point per point, but your lender’s rate sheet will show the actual pricing.
Can I buy points on a refinance?
Yes. The same break-even analysis applies. Points on a refinance are generally tax deductible over the life of the loan, if you itemize.
Can the seller pay for my points?
Yes, seller concessions can often be used for discount points, subject to your loan program’s limits on seller contributions.
Are points refundable if I sell early?
No. Points are prepaid interest and are not refunded if you sell, refinance, or pay off the loan early.
