Should I Buy Mortgage Points?

Pay $8,000 today to save $65.40 a month — good deal or expensive mistake? The answer is a single number: the break-even point. On a $400,000 loan, buying the rate down from 6.5% to 6.25% takes 10.2 years to pay for itself. Stay longer and you win; leave earlier and you paid for a discount you never collected. Here's the full math, plus the two alternatives lenders never quote.

What points actually buy

One "point" = 1% of the loan amount, paid at closing as prepaid interest. Two points on a $400,000 loan = $8,000 out of pocket on day one. In exchange, the lender drops your rate — typically about 0.25 percentage points per point, so 2 points might take you from 6.5% to 6.25%. The exact discount varies; always get the lender's specific quote rather than assuming the 0.25 rule.

Worked example: $400,000 at 6.5% vs 6.25%

The timeline decides everything: sell or refinance at year 7 and the points cost you $2,506 net (you collected $5,494 in savings but paid $8,000). Stay the full 30 years and you're ahead $15,545. The break-even isn't a suggestion — it's the entire decision.

Alternative 1: invest the $8,000 instead

Points aren't the only use of $8,000. Invested at 7%, it grows to about $15,952 by the 10.2-year break-even mark — while the points have merely repaid themselves to zero net. Over 30 years that $8,000 becomes roughly $60,898, dwarfing the points' $15,545 lifetime gain. The honest comparison isn't "points vs nothing" — it's "points vs every other use of the cash."

Alternative 2: put the $8,000 toward the down payment

Borrow $392,000 instead of $400,000 at 6.5%: the payment falls to $2,477.71 — a $50.57/month saving with no break-even period at all, since there's no upfront cost to recover. Total interest saved: about $18,204. It saves less per month than the points ($50.57 vs $65.40), but it starts saving on day one, helps your loan-to-value (closer to dropping PMI), and the money isn't lost if you move early.

How to compare quotes like a skeptic

Lenders rarely hand you a clean "0 points vs 2 points" choice — you have to construct it. Ask every lender for quotes at 0, 1, and 2 points on the same day (rates move daily; comparing Monday's 0-point quote to Wednesday's 2-point quote is meaningless). Then:

When points actually make sense

Assumptions and limits

Figures assume a $400,000 fixed-rate 30-year loan, 2 points = $8,000 buying exactly 0.25% off the rate, no other fee differences between the quotes, and the loan held to each stated horizon — validated against the amortization math our calculators use. Real quotes vary by lender and day; tax deductibility depends on your situation. Estimates for learning the math, not financial or tax advice.

Frequently asked questions

What are mortgage points?
Prepaid interest you buy at closing to lower your rate. One point costs 1% of the loan amount — $4,000 on a $400,000 loan — and typically cuts the rate by about 0.25 percentage points, though the exact discount varies by lender and market.
How do I calculate the break-even on points?
Divide the points cost by the monthly savings: $8,000 ÷ $65.40/month ≈ 122 months (10.2 years). Keep the loan past that point and the points pay off; sell or refinance before it and you lose money on the trade.
Do points make sense if I might move in a few years?
Usually not. If you sell or refinance before the break-even point, the unrecovered points cost is a pure loss — in our example, leaving at year 7 means the points cost you $2,506 net. Points reward staying put.
Are mortgage points tax deductible?
Points paid on a purchase mortgage are generally deductible as home mortgage interest in the year paid, if you meet IRS conditions (the loan is secured by your main home, paying points is customary in your area, and other requirements). Points on a refinance are usually deducted gradually over the loan term. Tax rules change — confirm your situation with a tax professional. This is general information, not tax advice.
What's the difference between discount points and origination points?
Discount points buy a lower rate; origination points (an origination fee) are the lender's charge for making the loan and don't reduce your rate. A quote with '1 point' could mean either — ask which one it is before comparing offers.
Can I negotiate points with my lender?
Yes — everything at closing is negotiable, including whether you pay points at all. Get quotes with 0, 1, and 2 points from the same lender on the same day, then compare break-evens. Lenders can also offer 'lender credits' (negative points): a slightly higher rate in exchange for cash toward closing.
