Mortgage Discount Points: Should You Buy Them?
A discount point costs 1% of your loan amount and typically lowers the rate by 0.25%. The break-even period — how long you need to stay in the loan for the savings to recoup the cost — is the only number that matters when deciding.
TL;DR
- One point = 1% of the loan amount, paid at closing. On a $400,000 loan, one point is $4,000.
- One point typically lowers the rate by 0.125%–0.25%, with most rate sheets in the 0.20%–0.25% range.
- Break-even is usually 4–7 years. If you'll stay longer than break-even, points likely save money.
- Points are tax-deductible as mortgage interest if itemizing — check current IRS guidance.
- Seller-paid points count as concessions and are usually deductible by the buyer.
What a discount point actually is
A discount point (also called a "mortgage point") is prepaid interest that lowers the interest rate on your loan. The lender collects the point at closing and uses it to reduce the long-term cost of capital on that loan.
The terminology is consistent across the industry:
- 1 point = 1% of the loan amount
- Points are paid at closing, separately from the down payment
- Points lower the note rate for the life of the loan (or until refinance/payoff)
- Fractional points are common — you might pay 0.5 points or 1.375 points
A typical rate sheet might show:
| Points | Rate | Cost on $400K loan | | --- | --- | --- | | 0 (par rate) | 7.000% | $0 | | 0.50 | 6.875% | $2,000 | | 1.00 | 6.750% | $4,000 | | 1.50 | 6.625% | $6,000 | | 2.00 | 6.500% | $8,000 |
The exact rate-per-point ratio varies by lender, loan program, day-to-day market conditions, and the bond market environment. Always ask for a current rate sheet showing the par rate and the buy-down options together.
The break-even calculation
Break-even is the only meaningful test of whether points are worth buying. The formula:
Break-even months = (Cost of points) ÷ (Monthly P&I savings)
Worked example
A buyer is comparing 7.00% with no points to 6.75% with 1 point on a $400,000 loan.
| Option | Rate | P&I monthly | Points cost | | --- | --- | --- | --- | | Option A (par) | 7.000% | $2,661 | $0 | | Option B (1 pt) | 6.750% | $2,594 | $4,000 |
Monthly savings: $2,661 − $2,594 = $67
Break-even: $4,000 ÷ $67 = 59.7 months, or about 5 years.
If the buyer plans to keep this loan for at least 5 years (no refinance, no sale), Option B is the better choice. From month 60 onward, the $67/month savings is pure benefit.
Adding 2 points
| Option | Rate | P&I monthly | Points cost | | --- | --- | --- | --- | | Option C (2 pts) | 6.500% | $2,528 | $8,000 |
vs. Option A:
- Monthly savings: $2,661 − $2,528 = $133
- Break-even: $8,000 ÷ $133 = 60.2 months, or about 5 years.
The second point has roughly the same break-even period as the first. This is generally how rate sheets are constructed — each point produces roughly proportional savings.
When points make sense
The general rule: if you'll keep the loan past the break-even period, points save money.
Buy points when:
- You plan to stay in the home long-term (7+ years for a 30-year fixed at typical break-evens)
- You have cash beyond the down payment, reserves, and closing costs that wouldn't be more productive elsewhere
- You expect rates to stay flat or rise (no incentive to refinance)
- You're using a 30-year fixed (longer time horizon to accrue the savings)
- You're in a higher tax bracket and itemize deductions (points are usually deductible as mortgage interest)
Don't buy points when:
- You expect to refinance within 3–5 years (you'll lose the unrecovered cost)
- You expect to sell or relocate within 3–5 years
- You're stretched on cash and would deplete reserves to buy points
- You're using an ARM (the rate will adjust regardless)
- The savings are marginal and the money would be more productive paying down high-interest debt, funding retirement, or earning a higher risk-free return
Points vs. lower price vs. larger down payment
A buyer with extra cash at closing often has three options for the same dollars:
- Buy discount points to lower the rate
- Increase the down payment to reduce loan amount (and possibly drop PMI)
- Negotiate the price down with the seller and keep cash
For a buyer with $4,000 of "extra" cash on a $400,000 purchase with 5% down:
| Option | Result | 5-year cost | | --- | --- | --- | | Buy 1 point, lower rate to 6.75% | $67/mo lower payment, but same PMI | ~$4,020 savings before break-even | | Add $4,000 to down payment | Loan becomes $376K, possibly lower PMI tier | ~$1,200–$2,400 savings (rate same, PMI may drop a tier) | | Negotiate $4,000 off price | Loan becomes $376K, same as option 2 | Same as option 2 |
Option 1 typically wins for buyers who will keep the loan past break-even. Option 2 or 3 can win when the $4,000 pushes you across a PMI tier boundary (95% LTV → 90% LTV is a common one) or eliminates PMI entirely.
Negative points (lender credits)
The reverse of buying points: you can take a higher rate in exchange for a closing-cost credit. This is called "negative points" or a "lender credit" or sometimes "premium pricing."
| Points | Rate | Cost or credit | | --- | --- | --- | | +1.00 (you pay) | 6.75% | +$4,000 | | 0.00 (par) | 7.00% | $0 | | −1.00 (you receive) | 7.25% | −$4,000 credit |
A lender credit can reduce or eliminate closing costs at the expense of a higher long-term payment. The same break-even logic applies in reverse: if you'll keep the loan a short time, taking a credit can be the right move because the cumulative rate cost stays small.

Seller-paid points
When a seller agrees to pay points on the buyer's behalf, the points are typically counted as a "seller concession" and limited by program:
| Loan type | Max seller concessions (owner-occupied primary) | | --- | --- | | Conventional 90%+ LTV | 3% of purchase price | | Conventional 80%–90% LTV | 6% of purchase price | | Conventional under 80% LTV | 9% of purchase price | | FHA | 6% of purchase price | | VA | 4% (concessions), unlimited closing cost credits | | USDA | 6% of purchase price |
Seller-paid points can be a powerful negotiation tool in buyer-friendly markets. A $400,000 purchase with the seller paying $8,000 to buy 2 points lowers the buyer's rate meaningfully and lowers the monthly payment without requiring the buyer to bring extra cash to closing.
The IRS generally allows the buyer to deduct seller-paid points as if the buyer had paid them directly. Check current IRS Publication 936 for the rules.
Temporary buydowns (2-1, 3-2-1)
Different from permanent discount points. A 2-1 buydown lowers the rate by 2 percentage points in year 1 and 1 percentage point in year 2, returning to the note rate in year 3. The buydown is funded by an upfront escrow that the lender draws down monthly to pay the rate difference.
A 3-2-1 buydown lowers the rate by 3 points in year 1, 2 in year 2, and 1 in year 3.
Temporary buydowns make most sense when:
- The buyer expects income to rise (medical resident, recent graduate, expected promotion)
- The seller is willing to fund the buydown as a concession
- Rates are expected to fall (refinance opportunity before the buydown expires)
A temporary buydown is not a permanent rate reduction. The qualifying rate for DTI purposes is the note rate, not the temporarily reduced rate.
What lenders won't always tell you
Two practices to know:
- Some lenders quote rates assuming you're buying points without making the par rate option obvious. Always ask: "What's the rate at zero points, and what's the cost to lower it by 0.25%?"
- The rate-per-point ratio shifts intraday with the bond market. The cost to buy down a quarter point in the morning might be $3,000; by afternoon it could be $4,500. If you're floating rate during a volatile market week, the math you ran on Monday may not apply by Thursday.
