Mortgage points let you pay money upfront in exchange for a lower interest rate — but whether that trade makes sense depends entirely on one calculation most buyers never run. This guide explains exactly what points cost, what they save, and how to know if buying them is the right move for you.

Who this guide is for

Anyone who's been offered the option to "buy down" their rate with points and wants to understand whether it's actually a good deal.

1. What mortgage points actually are

One discount point equals 1% of your loan amount, paid upfront at closing, in exchange for a reduced interest rate. On a $300,000 loan, one point costs $3,000. Points are entirely optional — you're never required to buy them, and lenders must offer a no-points option alongside any points-included quote.

Don't confuse discount points (which reduce your rate) with origination points, which are a lender fee unrelated to rate reduction — always clarify which type is being discussed in any quote.

2. How much points cost and save

Typical points pricing on a $300,000 loan

PointsApprox. rate reductionUpfront cost
0.5 pt~0.125%$1,500
1 pt~0.25%$3,000
2 pts~0.5%$6,000

These ratios are approximate and vary by lender and market conditions — always get the exact figures on your specific Loan Estimate.

3. The break-even math

The calculation is the same logic as refinancing: points cost ÷ monthly savings = months to break even. If you stay in the home beyond the break-even point, the points save you money. If you sell or refinance before then, you lose money on the points purchase.

Points typically break even in 4-7 years

This is a rough rule of thumb, not a guarantee — always calculate your specific numbers. If you're confident you'll keep the loan well beyond that window, points are usually worth considering. If you might move or refinance sooner, they usually aren't.

4. When points are worth it

Points are generally not worth it if you might move within a few years, if you're using your last available cash to buy them, or if you anticipate refinancing soon regardless of rate movements.

5. Worked example — to buy or not to buy

Worked example
Robert — deciding on 2 points on a $320,000 loan
$6,400 Cost of 2 points
6.95% → 6.45% Rate with points
12+ years Robert's planned stay

Without points: 6.95% rate, monthly P&I ≈ $2,118.

With 2 points ($6,400 upfront): 6.45% rate, monthly P&I ≈ $2,015.

Monthly savings: $103. Break-even: $6,400 ÷ $103 = approximately 62 months (just over 5 years).

Robert plans to stay in this home at least 12 years — well beyond the break-even point. Over the full 30-year loan term, the points will have saved him approximately $30,500 in reduced interest beyond their cost. For Robert's specific situation and timeline, buying the points is the financially sound choice.

Had Robert instead expected to move in 3-4 years, this same offer would have cost him money rather than saved it — illustrating why the decision depends entirely on individual circumstances, not the points offer alone.

Frequently asked questions

Points paid on a primary residence purchase are often deductible in the year paid, subject to specific IRS conditions. Points paid on a refinance are typically deducted gradually over the life of the loan rather than all at once. See IRS Publication 936 and consult a tax professional for your specific situation, as conditions and eligibility can vary.
Yes, in many cases — seller-paid points are a negotiable part of purchase contracts, particularly in buyer's markets. This effectively gets you a lower rate at no cost to you, making the break-even calculation irrelevant since you didn't pay for the points yourself.
These serve different purposes. A larger down payment reduces your loan amount and can eliminate PMI at the 20% threshold. Points reduce your rate on whatever loan amount you have. Run both calculations separately — sometimes a larger down payment to cross the PMI threshold offers better value than the same money spent on points.
Yes — this is sometimes called a "lender credit" and works in reverse. You accept a higher interest rate in exchange for a credit toward your closing costs, useful if you're short on upfront cash but plan to refinance or sell relatively soon, making the long-term rate cost less important than near-term cash flow.
