Walk into any mortgage closing and you'll face the same fork in the road: pay extra upfront for a lower rate, or keep your cash and accept a higher one.
It rarely is, because the math depends entirely on how long you actually stay in the house.
A discount point typically costs 1% of the loan amount and shaves roughly 0.25% off your interest rate.
On a $400,000 mortgage, that's $4,000 out of pocket to save about $60 a month.
Divide the upfront cost by the monthly savings and you get your break-even point — in this case, around 67 months, or more than five years.
That break-even number is where the sales pitch gets slippery.
A loan officer earns more when you buy points, and the pitch conveniently assumes you'll stay put long enough to come out ahead.
The average American homeowner now keeps a mortgage for about seven years before selling or refinancing, which leaves a thin margin for error.
Move in year four and you donated that $4,000 to the lender.
There's also the opportunity cost nobody mentions.
That $4,000 could pay down principal, cover closing costs, or sit in a high-yield savings account earning 4% or more.
Comparing a point to a savings account isn't apples to apples, but the point only wins if your break-even window is short and your alternative is doing nothing.
The reverse strategy deserves more attention than it gets.
Instead of paying points, many buyers take a slightly higher rate and ask the seller or builder to cover closing costs — a credit that reduces what you need at the table.
You keep your cash, and if rates fall later, you refinance without having sunk money into a rate you're about to abandon.
Refinancing is the quiet trap in all of this.
Points are gone the moment you refinance.
They don't transfer, they don't come back, and they don't reduce your payoff balance.
Anyone who bought points in 2021 at 3% has watched that money evaporate as rates climbed and the math on a future refi shifted.
Meanwhile, buyers who skipped points kept flexibility they can still use.
None of this makes points universally bad.
If you're putting down roots for the long haul, have cash beyond your emergency fund, and plan to stay past the break-even date with room to spare, buying the rate down can make sense.
Ask your lender for the break-even in writing, then ask yourself honestly whether you'll still be there.
One more thing worth checking: some lenders offer no-cost refinance features or temporary buydowns that shift the math entirely.
A 2-1 buydown, for example, lowers your rate in years one and two, then steps up.
It's a different tool with different risks, and it's often confused with points in the sales conversation.
Our take: points are a bet on your own inertia, and lenders know most people underestimate how often life interrupts a mortgage.
Unless the break-even lands comfortably inside your realistic timeline and the cash isn't needed elsewhere, keeping your money and your options is the smarter play.
Final Thoughts
Ask what the point actually buys, who profits from it, and what happens if you leave early.
