When your lender gives you a rate quote, the number often comes with an attached option: pay extra at closing to reduce that rate. Those prepaid interest charges are called discount points. Most buyers encounter them on their Loan Estimate and do not have a quick way to evaluate whether paying them makes financial sense. The answer depends almost entirely on one number: how long you plan to stay in the home.
What are mortgage discount points and how are they calculated?
A discount point is a fee you pay your lender upfront, at closing, in exchange for a lower interest rate on your mortgage. One point equals 1 percent of the loan amount. On a $400,000 loan, one point costs $4,000. Two points cost $8,000.
The rate reduction per point varies by lender, loan type, and market conditions. A commonly cited figure is 0.25 percentage points of rate reduction per point purchased, but lenders set their own rate-to-point schedules. The actual reduction may be 0.125 to 0.375 points per point paid depending on the lender and the rate environment. Always get the specific numbers in writing from your loan officer before making any decision.
Points appear on your Loan Estimate in Section A, labeled "Origination Charges," with a line showing the cost in dollars. They are paid at closing alongside your other closing costs.
Key takeaway
Discount points are a prepaid interest purchase, not a fee for a service. You pay more upfront in exchange for a lower rate over the life of the loan. Whether that tradeoff makes financial sense depends on how long you stay in the home.
How much does one discount point lower your interest rate?
The relationship between points and rate reduction is not standardized across lenders. On conventional loans in a 7 percent rate environment, a common schedule is approximately 0.25 percent rate reduction per point, according to guidance published by the Consumer Financial Protection Bureau. Some lenders offer steeper reductions; others offer less.
Here is an example using common figures:
| Scenario | Loan Amount | Rate | Monthly Payment (P+I) | Points Paid | Cost of Points |
|---|---|---|---|---|---|
| No points | $400,000 | 7.00% | $2,661 | 0 | $0 |
| 1 point | $400,000 | 6.75% | $2,594 | 1 | $4,000 |
| 2 points | $400,000 | 6.50% | $2,528 | 2 | $8,000 |
In the one-point scenario, the monthly savings is $67. In the two-point scenario, the monthly savings is $133.
These figures are illustrative. Your lender's actual rate-to-point schedule may differ.
How to calculate the break-even point on buying down your rate
Break-even is the month at which the cumulative monthly savings from the lower rate equals the upfront cost of the points.
The calculation is straightforward:
Break-even (months) = Cost of points / Monthly savings from lower rate
Using the one-point example above: $4,000 / $67 per month = approximately 60 months (5 years).
If you stay in the home past month 60 without refinancing, buying the point saves you money. If you sell or refinance before month 60, you paid $4,000 and did not recover it.
The break-even calculation is a minimum threshold, not a guarantee. It assumes you do not refinance before the break-even date. A refinance resets the clock because your new loan will have its own rate and terms.
When buying mortgage points makes financial sense
Points make the strongest financial case when:
You plan to stay long-term. If your break-even is 5 years and you expect to own the property for 10 to 15 years, you accumulate meaningful savings over the back half of that period. The longer you stay past break-even, the more the points pay back.
You have excess cash and have maximized your down payment. Putting cash into points rather than a larger down payment only makes sense if you are already at a comfortable loan-to-value ratio. A buyer who needs every dollar for down payment and closing costs should not deplete reserves to buy points.
Rates are elevated and you expect to hold without refinancing. In a high-rate environment where you believe rates will remain elevated for years, a bought-down rate provides concrete monthly savings. If you expect to refinance as rates drop, the calculation changes -- you may refinance before recovering the point cost.
The break-even is short. Some lenders offer favorable point-to-rate schedules that produce a break-even of 24 to 36 months. At that range, the decision becomes lower-risk.
When to skip discount points
Points are a poor use of cash when:
You plan to sell within 5 to 7 years. Most break-even timelines are in that range, meaning you will likely not recover the upfront cost before you sell.
You need the cash for your down payment or emergency reserves. Depleting savings to lower a monthly payment by $50 to $100 while leaving yourself with no financial cushion is a poor tradeoff.
You expect to refinance. If rates are expected to decline and you plan to refinance within 2 to 3 years, buying points on the current loan means paying a premium for a rate you will abandon before recovering the cost.
Warning
A lender who leads with a low rate without disclosing points may be offering a subsidized rate that comes with a significant upfront cost. Before comparing rate quotes across lenders, confirm what points, if any, are included in each quote. Section A of the Loan Estimate shows this in dollars.
Origination points vs. discount points: what is different
These two fees both appear on the Loan Estimate and are both measured in "points," but they serve different purposes.
Origination points are the lender's fee for processing your loan. They are a cost of doing business with that lender, not a rate-reduction mechanism. They are negotiable.
Discount points are optional prepaid interest you choose to pay to buy down your rate. They appear on the same line of your Loan Estimate but are a choice, not a fixed charge.
When comparing lenders, ask each for a quote with zero discount points so you can compare baseline origination costs fairly. Then request a separate quote showing what rate reduction buying one or two points would produce with that lender, so you can evaluate the math.

How mortgage points appear on your loan estimate and closing disclosure
On the Loan Estimate (received within 3 business days of application), discount points appear in Section A, "Origination Charges," as a percentage of the loan amount and a dollar equivalent. A line might read: "Discount Points (0.500%)" next to a dollar figure of $2,000 on a $400,000 loan.
On the Closing Disclosure (received at least 3 business days before closing), the same information appears in the Loan Costs section. You can compare it to the Loan Estimate to confirm nothing changed outside tolerance limits.
If points appear on your Loan Estimate but you did not request them, ask your loan officer to clarify whether they are origination fees or discount points, and whether removing the points changes the quoted rate.

Tip
If you are unsure whether points make sense for your situation, ask your loan officer to run the break-even calculation in writing. Any loan officer who cannot produce this in under 5 minutes, or who discourages you from asking, is a reason to get a second quote from a different lender.
Frequently asked questions
Are mortgage discount points tax deductible?
Points paid on a purchase mortgage for your primary residence are generally deductible in the year you pay them, according to IRS Publication 936. Points on a refinance must be deducted over the life of the loan rather than all at once. Consult a tax professional about your specific situation before counting on the deduction at filing.
Can I roll the cost of discount points into my loan?
Lenders typically do not allow you to finance discount points into the loan balance, because the whole purpose is to reduce the rate by paying cash upfront. However, some loan programs allow seller concessions or lender credits to cover point costs. Ask your loan officer specifically whether any available credits can offset the point purchase.
Do mortgage points make sense if I plan to sell in five years?
Probably not. If your break-even timeline is 72 months and you plan to sell at month 60, you pay the upfront cost but never recover it through monthly savings. Run the break-even calculation for your specific rate and loan amount before deciding. Short-term ownership is the main reason most buyers are better off skipping points.
What is a negative point or lender credit?
A lender credit is the reverse of a discount point: the lender pays you a credit toward closing costs in exchange for a higher interest rate. If you are short on closing cost cash but can afford a slightly higher monthly payment, a lender credit reduces your upfront cash requirement. The tradeoff is a higher rate for the life of the loan.
How do I find out if my rate quote includes points?
Check Section A of the Loan Estimate, labeled 'Origination Charges.' Discount points appear there as a percentage of the loan amount with a dollar equivalent. A rate quote that includes points is not a better deal by definition -- it is a different tradeoff. Ask your lender for a no-point rate quote alongside any quoted rate so you can compare both options directly.
Can I negotiate with a lender to reduce origination points?
Yes. Origination points (which cover the lender's fee for making the loan) are negotiable and sometimes waivable. Discount points are also a choice, not a fixed charge. Shopping multiple lenders and comparing their Loan Estimates is the most reliable way to identify when one lender is charging more points than the market requires for the same rate.
