What Is a Mortgage Point?
One mortgage (discount) point costs 1% of your total loan amount, paid as cash at closing, in exchange for a permanently lower interest rate on the loan. On a $400,000 mortgage, one point costs $4,000. Points can typically be purchased in fractional amounts too (a half-point, a quarter-point), not just whole numbers, and most lenders allow buying multiple points, though the rate reduction per point may diminish slightly as you buy more.
How Much Rate Reduction Do You Actually Get?
There's no universal fixed rule, but a commonly cited rough industry benchmark is that 1 point reduces your rate by about 0.25 percentage points (a range of roughly 0.125–0.375 points is also commonly seen depending on the lender and market). This ratio shifts with overall interest rate conditions and varies by lender, so always ask your specific lender for their exact points-to-rate table rather than assuming the 0.25% rule of thumb applies precisely to your loan.
| Points Purchased | Illustrative Cost (on $400,000 loan) | Illustrative Rate Reduction |
|---|---|---|
| 0 points | $0 | Base rate offered |
| 1 point | $4,000 | ~0.25% lower |
| 2 points | $8,000 | ~0.5% lower |
The Break-Even Math
If it takes longer to break even than you plan to keep the loan (before selling or refinancing), buying points is a net loss.
The monthly payment savings from a lower rate depends on your loan amount and term — even a modest rate reduction produces a real, permanent monthly savings for the life of the loan, so the break-even calculation is really a question of "how many months until the cumulative savings pays back the upfront cost," after which every additional month is pure savings.
Worked Example
A $400,000, 30-year fixed mortgage at 7.00% has a certain monthly principal & interest payment; buying 1 point for $4,000 drops the rate to 6.75%:
| Scenario | Rate | Approx. Monthly P&I Payment |
|---|---|---|
| No points | 7.00% | ~$2,661 |
| 1 point ($4,000) | 6.75% | ~$2,595 |
Monthly savings: ~$2,661 − ~$2,595 = ~$66/month. Break-even: $4,000 ÷ $66 ≈ 61 months (about 5 years). If this buyer plans to stay in the home and keep this exact loan for more than roughly 5 years, buying the point pays off; if they expect to sell or refinance sooner, it doesn't.
When Buying Points Is Worth It
- You're confident you'll keep the loan past the break-even point — a forever home, or a loan you don't expect to refinance for many years.
- You have the cash available without depleting your emergency fund or stretching your down payment/closing cost budget uncomfortably thin.
- Rates are relatively high and you expect them to stay elevated — since you likely won't refinance soon (refinancing resets the break-even clock on any points paid).
- You want a lower required monthly payment for debt-to-income or budgeting reasons, and paying cash upfront is available to you.
When Buying Points Is NOT Worth It
- You expect to sell or refinance within a few years — you'll likely never recoup the upfront cost.
- You'd have to reduce your down payment or drain savings to afford the points — the opportunity cost and reduced financial cushion often outweighs the rate benefit.
- You expect rates to fall and plan to refinance soon — paying to lower a rate you intend to replace shortly is generally wasted money.
- The cash could pay down higher-interest debt instead — if you're carrying credit card or other high-rate debt, paying that off first usually beats buying mortgage points.
Discount Points vs Origination Points
Not all "points" on a loan estimate lower your rate — there are two distinct types, and it's important not to confuse them:
- Discount points — what this guide covers: optional, paid to buy down your interest rate.
- Origination points — a fee the lender charges for processing/originating the loan, unrelated to your interest rate. This is effectively a lender fee, not a rate-reduction tool, though it's sometimes labeled using the same "point = 1% of loan" terminology.
Always check your Loan Estimate document carefully to see which type of point you're being quoted, since only discount points reduce your rate.
Negative Points / Lender Credits
The reverse transaction also exists: some lenders offer a "lender credit" (sometimes called negative points) — you accept a slightly higher interest rate in exchange for the lender covering some of your closing costs. This can make sense if you're short on cash at closing but plan to keep the loan for a shorter period, essentially the mirror image of the points-buying decision, evaluated with the same break-even logic in reverse. Buyers who know they'll likely refinance or sell within a few years — a starter home, a job relocation on the horizon, or an ARM used deliberately as a short-term bridge — are the group most likely to benefit from taking a lender credit instead of paying points, since they'd never reach the points break-even point anyway, and the upfront cash saved can instead go toward the down payment, reserves, or other moving costs.
Points on a Refinance
The points decision applies just as much to refinancing an existing mortgage as to a new purchase loan, with one added wrinkle: your break-even clock effectively restarts with the refinance, and if you already paid points on your original loan, you may not have fully recovered that earlier cost before refinancing again. When evaluating points on a refinance, calculate the break-even period for the new points independently, and factor in the total closing costs of the refinance itself (not just the points) against your monthly payment savings — a refinance only makes sense once the full package of costs is recovered within your realistic time horizon for keeping the new loan.
Why Comparing Lenders on Points Matters
Because the exact rate reduction per point isn't standardized, the same $4,000 spent on points with two different lenders can produce noticeably different rate outcomes. This is one of the most overlooked reasons to shop multiple lenders when getting a mortgage: ask each lender for their specific rate sheet showing the rate available at 0 points, 1 point, and 2 points, and compare the actual break-even math side by side, rather than assuming all lenders offer an identical points-to-rate ratio. Federal disclosure rules require lenders to show points clearly on your Loan Estimate, making this comparison straightforward once you have quotes from more than one lender in hand.
Points and Your Overall Cash-at-Closing Picture
Buying points competes directly with every other use of cash at closing — a larger down payment, a bigger emergency-fund cushion after move-in, or covering other closing costs. Because a larger down payment can also reduce or eliminate private mortgage insurance (PMI) on a conventional loan, and PMI itself is an ongoing monthly cost separate from your interest rate, it's worth running the numbers on whether extra cash is better spent pushing your down payment past a PMI-elimination threshold rather than buying rate points — in some cases eliminating PMI produces a larger monthly savings than the equivalent amount spent on points would. There's no universal answer; it depends on your specific loan-to-value ratio, PMI rate, and the points-to-rate ratio your lender is offering, so it's worth asking your loan officer to run both scenarios side by side before deciding where your available closing cash does the most good.
