Mortgage Points Explained — When to Buy Down Your Rate
points">What Are Mortgage Points?
Mortgage points — also called “discount points” — are upfront fees you pay to your lender at closing in exchange for a lower interest rate on your loan. Each point costs 1% of the loan amount and typically reduces your rate by 0.25%. On a $400,000 loan, one point costs $4,000 and might lower your rate from 6.50% to 6.25%.
Points are essentially prepaid interest. You’re paying a lump sum upfront to reduce the amount of interest you pay each month for the life of the loan. Whether this makes financial sense depends on how long you keep the mortgage.

How Points Reduce Your Rate
| Points Purchased | Cost ($400K Loan) | Rate Reduction | New Rate (from 6.50%) | Monthly Payment | Monthly Savings |
|---|---|---|---|---|---|
| 0 points | $0 | — | 6.50% | $2,528 | — |
| 0.5 points | $2,000 | -0.125% | 6.375% | $2,496 | $32 |
| 1 point | $4,000 | -0.25% | 6.25% | $2,463 | $65 |
| 2 points | $8,000 | -0.50% | 6.00% | $2,398 | $130 |
The rate reduction per point isn’t fixed — it varies by lender, market conditions, and the base rate. In some environments, one point buys 0.25%; in others, it might buy 0.20% or 0.30%. Always ask your lender for the specific buydown pricing.
The Break-Even Calculation
The break-even point is the number of months it takes for your monthly savings to recoup the upfront cost of the points. After that, every month is pure savings.
Formula: Break-even months = Points cost ÷ Monthly savings
Example: 1 point on a $400,000 loan costs $4,000 and saves $65/month.
Break-even: $4,000 ÷ $65 = 61.5 months (approximately 5 years and 2 months)
| Scenario | Points Cost | Monthly Savings | Break-Even | 10-Year Savings | 30-Year Savings |
|---|---|---|---|---|---|
| 1 point on $300K | $3,000 | $49 | 61 months | $2,880 | $14,640 |
| 1 point on $400K | $4,000 | $65 | 62 months | $3,800 | $19,400 |
| 2 points on $400K | $8,000 | $130 | 62 months | $7,600 | $38,800 |
| 1 point on $600K | $6,000 | $98 | 61 months | $5,760 | $29,280 |
If you plan to stay in the home longer than the break-even period, buying points saves money. If you’ll sell or refinance before break-even, you’re better off keeping the cash.
When Buying Points Makes Sense
- You plan to stay 7+ years: With a typical 5-year break-even, staying 7+ years gives you 2+ years of net savings.
- You have excess closing cash: If you have cash beyond your down payment and emergency reserves, points are a guaranteed return on investment (unlike stock market investments).
- You want to reduce your monthly obligation: Lower monthly payments provide budget flexibility, especially in high-cost markets.
- Rates are high and you don’t expect to refinance soon: If you’ll hold this mortgage for a long time, the upfront cost pays off handsomely.
- You’re buying a forever home: The longer the holding period, the greater the return from points.
When to Skip Points
- You might move within 5 years: You won’t reach break-even, and the money spent on points is gone.
- You plan to refinance if rates drop: Refinancing restarts the break-even clock. Points on a loan you’ll only hold for 2-3 years are wasted.
- You need the cash elsewhere: If spending $4,000 on points means depleting your emergency fund, the financial risk outweighs the interest savings. Keep reserves of at least 3-6 months of expenses.
- The rate spread is small: If one point only buys a 0.15% reduction, the break-even stretches beyond 7 years — less attractive.
- You’re getting a shorter-term loan: On a 15-year mortgage, the monthly savings per point are smaller because the loan already amortizes faster. The break-even period can extend beyond the practical benefit window.
Origination Points vs Discount Points
Don’t confuse discount points (rate buydown) with origination points (lender fee):
| Type | Purpose | Reduces Rate? | Negotiable? |
|---|---|---|---|
| Discount points | Prepaid interest to lower your rate | Yes | You choose how many to buy |
| Origination points | Lender’s processing fee | No | Yes — shop between lenders |
Origination fees are a cost of getting the loan, not a rate-reduction tool. Some lenders charge 0.5-1.0% origination; others charge zero origination with a slightly higher rate. When comparing lender quotes, separate discount points (your choice) from origination fees (their charge) to make accurate comparisons.
Lender Credits (Negative Points)
The opposite of buying points is accepting lender credits — sometimes called “negative points.” The lender gives you a credit toward closing costs in exchange for a higher interest rate.
Example: Instead of 6.50% with $0 in credits, you accept 6.75% and receive a $3,000 lender credit that offsets your closing costs.
Lender credits make sense when:
- You’re short on closing cash
- You plan to sell or refinance within 3-5 years (the higher rate costs less than the credit you received)
- You want to minimize out-of-pocket costs at closing
The break-even works in reverse: after a certain number of months, the higher monthly payment has cost you more than the credit saved. Calculate both directions before choosing.
Seller-Paid Rate Buydowns
Sellers can pay for points as a concession to the buyer. This is increasingly common in the current market, where sellers offer 2-1 or 1-0 temporary buydowns to make their listings more attractive:
- Permanent buydown: Seller pays points to permanently reduce the buyer’s rate. The seller spends $4,000-$8,000; the buyer gets a lower rate for the life of the loan.
- Temporary 2-1 buydown: Seller pays a lump sum to reduce the buyer’s rate by 2% in Year 1 and 1% in Year 2, after which the full rate applies. On a $400,000 loan at 6.50%, the buyer pays as if the rate were 4.50% in Year 1 and 5.50% in Year 2. Cost to the seller: roughly $8,000-$10,000.
If you’re buying, ask about seller-paid buydowns as an alternative to a price reduction. A $10,000 price reduction saves roughly $18/month on a 30-year loan. A $10,000 seller-paid temporary buydown saves $400+/month in Year 1. The cash flow difference is dramatic. Check our closing costs guide for typical seller concession limits.
Are Points Tax-Deductible?
Discount points on a purchase mortgage are generally deductible in the year you pay them if you itemize deductions. Points on a refinance must be amortized (deducted proportionally) over the life of the loan.
- Purchase points: Fully deductible in the year of purchase
- Refinance points: Deducted proportionally over the loan term (e.g., $4,000 in points on a 30-year loan = $133/year)
- Seller-paid points: The buyer can deduct seller-paid points, even though the seller funded them
Consult a tax professional — the deductibility of points interacts with your total mortgage interest deduction, the $750,000 qualified mortgage limit, and whether you itemize or take the standard deduction.

Frequently Asked Questions
How many points can I buy?
Most lenders allow up to 3-4 points, though buying more than 2 is uncommon. The marginal rate reduction typically decreases with each additional point, making the third or fourth point less cost-effective than the first.
Can I buy fractional points?
Yes. You can buy 0.5 points, 0.75 points, or any fraction. Lenders price fractional points proportionally. Half a point on a $400,000 loan costs $2,000 and reduces the rate by approximately 0.125%.
Do points make sense on an ARM?
Generally no. Points buy down the initial fixed rate on an ARM, but since that rate only lasts 5-7 years, the break-even period may extend beyond the fixed period. On a 7/1 ARM where you plan to sell at Year 5, buying points is unlikely to pay off.
Should I buy points or make a larger down payment?
If you’re putting less than 20% down, the extra cash toward your down payment may eliminate PMI — which could save more per month than the rate reduction from points. Run both scenarios through the estimate your monthly payment to compare. If you’re already at 20% down, points are the better use of additional funds.
Can I negotiate point pricing?
You can shop between lenders for the best point pricing. The rate reduction per point varies by lender and market conditions. Get quotes from 3-4 lenders and compare the discount point schedules alongside their base rates and fees.
