I was going over a loan estimate with a borrower a few months back, and I got to the section that lists discount points, and I watched his eyes just kind of glaze over. He stopped me and said, “Wait, what is this? Nobody’s ever explained this to me before.” And that’s honestly more common than you’d think. A lot of people have never even heard the term “mortgage points” before they’re sitting at a closing table looking at a loan estimate with a line item they don’t understand. If you’re wondering whether you should buy mortgage points, you’re not alone. It’s a question that comes up all the time. So let’s back all the way up and talk through this the way I’d talk through it with someone sitting across my desk, because whether or not to buy mortgage points is one of those decisions that sounds complicated but really just comes down to a piece of simple math almost nobody actually does. Here’s the Mistake I See Constantly There are two mistakes I run into with points, and they’re opposites of each other, which is kind of interesting. The first mistake is the borrower who buys points automatically because it “sounds smart.” Lower rate, lower payment, what’s not to like? They see the number drop on paper and they go for it without ever asking how long it actually takes to get that money back. The second mistake is the borrower who’s heard points are some kind of upsell or gimmick, so they refuse to even consider them, no matter what the numbers actually say. They wave it off without ever running the math either. Here’s where people get tripped up either way: they’re making a decision based on a feeling instead of a calculation. And the truth is, whether points make sense has almost nothing to do with feelings. It’s a straightforward breakeven calculation, and once you know how to run it, the answer becomes pretty obvious for your specific situation. What a Mortgage Point Actually Is, in Plain English A discount point is money you pay upfront, at closing, in exchange for a lower interest rate for the life of your loan. One point costs 1% of your loan amount. So on a $400,000 loan, one point costs $4,000. Simple enough so far. Here’s what most buyers don’t realize: how much a point actually lowers your rate isn’t fixed. It changes depending on the lender, the loan program, and what’s happening in the broader rate market on any given day. Sometimes a point knocks a quarter percent off your rate. Sometimes it’s less than that. There’s no universal rule that says “one point equals exactly this much rate reduction,” no matter what you might read online. You have to look at the actual numbers your lender is quoting you that day. This is one of the biggest misconceptions I run into: people assume points work the same everywhere, like a fixed menu price. They don’t. That’s exactly why the breakeven math matters so much more than any general rule of thumb. The Breakeven Calculation: This Is the Only Math That Actually Matters Here’s the whole concept, and it’s simpler than people expect. You take whatever the points cost you, and you divide that by how much you’re saving every month on your payment. That tells you how many months, or years, it takes before those upfront savings actually pay you back. Let’s say you’re paying $7,000, or $10,000, or $20,000 for points, and you’re only saving $60 or $100 a month on your payment. If your breakeven point lands at 10 years, or 12 years, it doesn’t make much sense for most borrowers. But if that breakeven point is sitting at 3 years, or 5 years, now we’re having a real conversation, because that starts to look like a genuinely smart move depending on your plans. Let me walk through a real example the way I would with a borrower in my office. Example: A $14,000 Point Purchase Say you’re paying $14,000 for points on your loan, and that gets you a rate reduction that saves you $200 a month. Divide $14,000 by $200, and you get 70 months. That’s five years and ten months before you actually break even on that upfront cost. So what does that actually mean in practice? It means for the first five years and ten months, you haven’t saved a single dollar. You’ve just been slowly paying yourself back the $14,000 you handed over at closing. You don’t start seeing real, in-your-pocket savings until month 71. Points Cost Monthly Savings Breakeven Point Makes Sense If You’ll Stay… $7,000 $100/mo 70 months (~5 yrs 10 mo) Beyond 6 years $10,000 $100/mo 100 months (~8 yrs 4 mo) Beyond 8-9 years $14,000 $200/mo 70 months (~5 yrs 10 mo) Beyond 6 years $4,000 $65/mo 62 months (~5 yrs 2 mo) Beyond 5-6 years $4,000 $110/mo 36 months (3 years) Beyond 3 years Look at how much that last row changes the picture. Same $4,000 cost as the row above it, but a bigger monthly savings pulls the breakeven down to 3 years instead of over 5. That’s the entire game with points: it’s not just about how much they cost, it’s about how much they actually save you each month relative to that cost. Two loans can have the exact same point cost and completely different breakeven timelines depending on the rate reduction you’re actually getting. The Question That Decides Everything: How Long Are You Actually Staying? Once you’ve got your breakeven number, there’s really only one more question that matters: how long do you realistically expect to stay in this house, with this loan, before you sell or refinance? If someone thinks they’re going to sell the house, or refinance, within a five to seven year period, buying points usually doesn’t make sense, especially if the breakeven point is sitting out past that window. And here’s the thing, you’re going
