What a discount point actually buys you
A discount point is an upfront fee, paid at closing, equal to 1% of your loan amount, in exchange for a lower interest rate for the life of the loan. On a $420,000 loan, one point costs $4,200. Lenders typically price a point at roughly a 0.25% reduction in rate, though the exact ratio varies by lender and by market conditions, and most will let you buy a fraction of a point, not just whole increments.
It's effectively prepaid interest: you're trading a lump sum now for a smaller monthly payment for as long as you hold the loan. That trade only pays off if you keep the loan long enough for the monthly savings to exceed what you paid upfront, which is the break-even math we'll walk through below.
What a lender credit is, the mirror image
A lender credit works the same way in reverse. Instead of paying money to lower your rate, you accept a slightly higher rate in exchange for a credit toward your closing costs, sometimes enough to cover them entirely. This is common for buyers who are cash-tight at closing but plan to refinance in a few years, or who simply want to minimize the money they bring to the table even though it costs more over time.
A useful way to think about it: discount points and lender credits sit on the same dial, just turned in opposite directions. Moving the dial one way trades cash now for a cheaper rate later; moving it the other way trades a slightly more expensive rate for cash back today. Some buyers negotiate a credit directly from the seller instead of the lender, where the seller agrees to cover a set dollar amount of the buyer's closing costs as part of the purchase agreement, a different mechanism with a similar effect on how much cash the buyer needs at closing.
Comparing two offers: rate, points and APR side by side
Say two lenders quote you the same $420,000, 30-year loan, but structure it differently:
| Offer | Rate | Points | Upfront cost | APR |
|---|---|---|---|---|
| Lender A — no points | 6.75% | 0 | $0 | 6.81% |
| Lender B — 1 point | 6.50% | 1.0 | $4,200 | 6.60% |
| Lender C — 2 points | 6.25% | 2.0 | $8,400 | 6.39% |
The sticker rate makes Lender C look like the obvious winner. The APR column, which spreads the upfront points over the life of the loan, tells you how much that lower rate actually costs you to access, and makes the three offers genuinely comparable on a single number rather than two.
The break-even math on buying points
Take Lender B above: paying $4,200 upfront drops the rate from 6.75% to 6.50%, which lowers the monthly payment by roughly $69. Divide the upfront cost by the monthly savings: $4,200 ÷ $69 ≈ 61 months, or about five years. If you plan to stay in the home and keep this loan longer than that, buying the point saves you money overall. If you expect to sell or refinance sooner, the upfront cost likely won't pay itself back.
This is the single most useful calculation in the points-vs-no-points decision, and it's worth asking any lender quoting you points to walk through it on your specific numbers rather than taking "it'll save you money" at face value.
When points make sense, and when they usually don't
- Points tend to make sense when you're confident you'll hold the loan past the break-even point, you have the cash available without stretching your emergency fund, and you're not planning to refinance soon regardless of where rates go.
- Points tend not to make sense when you expect to move or refinance within a few years, when the cash would be better used for your down payment or reserves, or when rates are trending down and a future refinance is likely anyway.
Reading a loan estimate without getting lost
Every lender is required to give you a standardized three-page Loan Estimate within three business days of application, and the first page is where rate, points, and APR all live together. A few things worth checking line by line:
- Loan terms (page 1, top): loan amount, interest rate, and whether the rate can change.
- Projected payments: principal, interest, and estimated taxes and insurance combined.
- Costs at closing: total closing costs including any points you've chosen to pay.
- APR (page 3): the single number meant to let you compare total cost across lenders quoting different points and fees.
Comparing three Loan Estimates side by side on paper, rather than three rates quoted over the phone on different days, is the most reliable way to see which offer is actually cheaper once everything is accounted for. It's worth asking each lender for their estimate on the same day, ideally within a few hours of each other, since the underlying bond market can move enough overnight to muddy an otherwise clean comparison.
One more line worth tracking down: the "cash to close" figure, which combines your down payment, closing costs, and any points, minus any credits, into the single number you'll actually need to bring to the table. Two offers can show similar monthly payments and still require meaningfully different amounts of cash upfront, which matters just as much as the APR if your savings are the tighter constraint.
