If a lender has offered to lower your interest rate in exchange for cash at closing, you’re looking at mortgage points — and the math behind whether they’re worth it isn’t always obvious. Here’s how points work, how to calculate the real cost, and how to figure out your break-even period before you decide.
What Are Mortgage Points?
A mortgage point (also called a “discount point”) is a fee you pay upfront to your lender in exchange for a lower interest rate on your loan. One point equals 1% of your total loan amount.
So on a $400,000 loan:
- 1 point = $4,000, typically buys your rate down by roughly 0.25%
- 2 points = $8,000, roughly 0.50% off your rate
- 0.5 points = $2,000, roughly 0.125% off your rate
That 0.25%-per-point rule of thumb varies by lender, loan program, and market conditions — some lenders offer more or less rate reduction per point depending on the day’s pricing. Always ask your loan officer for the specific point-to-rate table on your quote rather than assuming the standard ratio.
A Worked Example: What Do 2 Points Actually Cost?
Let’s say you’re financing $500,000 and your lender quotes you 2 points to drop your rate from 6.75% to 6.25%.
- Cost of 2 points: 2% × $500,000 = $10,000 paid at closing
- Monthly payment at 6.75% (principal & interest): approximately $3,244
- Monthly payment at 6.25%: approximately $3,079
- Monthly savings: approximately $165
To find your break-even point — the point at which your upfront cost is fully recovered by monthly savings — divide the cost by the monthly savings:
$10,000 ÷ $165 per month ≈ 61 months (about 5 years)
If you plan to stay in the home and keep this loan longer than 5 years, buying the points saves you money over the life of the loan. If you expect to sell or refinance sooner than that, you’d likely come out ahead by taking the higher rate and keeping the $10,000 in hand.
(Figures above are illustrative. Use current rate quotes from your lender for an exact calculation — the actual rate/point ratio and payment numbers will vary based on the day’s market pricing and your loan program.)
How to Calculate Your Own Break-Even Point
- Get your no-points rate and payment from your lender’s loan estimate.
- Get your rate and payment with points at each point level offered (0.5, 1, 2, etc.).
- Subtract the with-points payment from the no-points payment to find your monthly savings.
- Divide the total upfront cost of the points by that monthly savings figure.
That result is the number of months you need to keep the loan for the points to pay for themselves. Anything beyond that is pure savings; anything short of it means the points cost you more than they saved.

When Buying Points Usually Makes Sense
- You’re confident you’ll stay in the home (or keep this specific loan) well past the break-even period
- You have the cash available without depleting your emergency reserves or down payment cushion
- Rates are elevated and you expect to hold the loan through a full rate cycle rather than refinancing soon
- You’re financing a long-term rental or investment property you don’t plan to sell
When Buying Points Usually Doesn’t Make Sense
- You expect to sell, relocate, or refinance within the next few years
- The upfront cash would be better used toward your down payment, reducing PMI, or building reserves
- You’re already stretching your budget to close — tying up more cash in points adds risk
- Rates are trending downward and a refinance in the near term is plausible, which would erase your point investment before break-even
Points vs. Other Uses for the Same Cash
Before committing to points, it’s worth comparing that upfront cost against alternatives:
- A larger down payment reduces your loan amount directly and may eliminate PMI depending on your equity position
- Paying down other debt may improve your DTI and free up qualifying room
- Keeping it as reserves protects you against needing to sell or refinance early, which is exactly the scenario where points lose their value
Running the numbers side by side — rather than evaluating points in isolation — usually gives the clearest answer.
Bottom Line
Mortgage points aren’t automatically good or bad — they’re a trade of cash now for savings later, and the right call depends entirely on your break-even timeline and how confident you are in your holding period. Run your specific numbers before deciding, and don’t be afraid to ask your loan officer for the break-even math in writing as part of your loan estimate comparison.
