Mortgage lenders love to pitch the "buy down your rate" option at closing, and it sounds like a no-brainer: pay a little extra now, save a lot later.
But the math only works for a specific kind of borrower, and plenty of people who pay for points never stick around long enough to break even.
One discount point costs 1% of your loan amount and typically shaves about 0.25% off your interest rate.
On a $400,000 mortgage, that's $4,000 upfront to drop your rate from, say, 6.75% to 6.5%.
Your monthly payment falls by roughly $63.
Divide the $4,000 by $63 and you get about 63 months — a little over five years — before you've recouped a dime.
That break-even window is the whole ballgame.
Sell the house, refinance, or get transferred before year five, and you handed the lender free money.
Stay for 15 years, and the savings can run into five figures.
The lender isn't being generous with that pitch — they're betting you won't last.
The catch is that nobody knows their own timeline.
The average American homeowner stays in a home about eight to ten years, but that's an average, not a promise.
Job changes, divorces, growing families, and falling rates all scramble the plan.
If rates drop to 5.5% in two years, you'll refinance and your points vanish into the lender's pocket.
There's also a quieter trap: points are paid upfront in cash, but the benefit arrives slowly.
That cash could sit in a high-yield savings account earning 4% or more right now, or fund an emergency buffer.
A $4,000 cushion matters more than a $63 monthly discount if your furnace dies in February.
They make the most sense for buyers who are certain they'll stay put for at least seven to ten years, have cash beyond their down payment and closing costs, and plan to keep the loan.
Retirees on fixed incomes sometimes value the lower payment.
So do buyers in expensive markets stretching to qualify.
The smarter move is to ask your lender for a side-by-side: one loan with points, one without, both showing the total cost over 5, 10, and 15 years.
Some lenders also offer lender credits — the reverse trade, where you take a slightly higher rate for lower closing costs.
That's often the better deal for anyone who might move or refinance.
Don't let a slick rate sheet decide this for you.
Ask what the break-even month is, write it down, and be honest about whether you'll still be in that house when it arrives.
The mortgage industry profits when borrowers pay upfront and leave early, so treat points as a bet, not a discount.
Run your own numbers, assume your life will change, and remember that flexibility is worth real money.
Final Thoughts
Sometimes the cheaper loan is the one that lets you walk away.
