Walk into any mortgage closing and you'll hear the same pitch: pay a little extra now, shave your interest rate for the next 30 years.
It sounds like a no-brainer, especially with rates still hovering well above the 3% era that spoiled everyone.
But "buying points" is one of those deals where the math cuts both ways, and the people selling it rarely mention the fine print.
One discount point costs 1% of your loan amount and typically knocks your rate down by about 0.25%.
On a $400,000 mortgage, that's $4,000 upfront to save roughly $60 a month.
Sounds fine until you do the break-even math: dividing $4,000 by $60 puts you at about 67 months—nearly six years—before you've recouped a single dollar.
That timeline is the whole ballgame, and it's where most buyers get sloppy.
If you sell, refinance, or get transferred before year six, you handed the lender thousands of dollars for nothing.
Points are paid in cash at closing and don't come back when the loan dies.
The savings only materialize if you stay put long enough, and life has a way of ignoring your spreadsheet.
There's a second trap: points are often rolled into the loan balance instead of paid upfront.
That feels painless, but now you're paying interest on the fee itself, sometimes for decades.
You've turned a one-time cost into a compounding one.
Lenders love this because it raises the loan amount and the total interest they collect—while you feel like you got a deal.
Then there's the tax angle, which gets oversold at kitchen tables.
Points on a purchase mortgage are sometimes deductible in the year you pay them, but rules are strict, and the standard deduction swallows the benefit for a lot of households.
On a refinance, you generally have to spread the deduction across the loan's life.
Ask a tax professional—not your loan officer, whose paycheck depends on closing the deal.
When you're certain you're staying long-term, you have the cash sitting in a savings account earning less than your mortgage rate, and you've compared the break-even against simply making extra principal payments.
That last comparison is the one nobody runs.
Paying down principal reduces what you owe forever and keeps your flexibility.
For everyone else—first-time buyers stretching for a down payment, anyone likely to move within five years, people who might refinance if rates drop—skipping points and keeping the cash is the more honest choice.
A slightly higher rate with a smaller loan and a healthy emergency fund beats a lower rate and an empty bank account every time.
They're a legitimate tool with a real trade-off, and the sales pitch conveniently hides half of it.
My take: treat points like any other financial bet, because that's exactly what they are.
Final Thoughts
Ask what your break-even is, ask who profits if you don't make it, and remember that the lender wins whether you stay or go.
