Mortgage Points: Paying Extra Upfront to Buy a Lower Rate — When It Actually Pays Off

When you get a mortgage, the lender will offer you a choice that sounds like a trick: pay extra money upfront and your interest rate goes down. These upfront payments are called mortgage points, or discount points, and one point costs 1 percent of the loan amount. On a $300,000 mortgage, one point is $3,000. In exchange, your rate typically drops by about 0.25 percent per point, though that varies by lender and market. Pay $6,000 for two points and your rate might fall from 7 percent to 6.5 percent. The question is whether that trade ever makes sense, and the answer is a math problem with one key variable: how long you stay in the house.

Run the numbers on that $300,000 loan. At 7 percent over 30 years, the monthly payment is about $1,996. At 6.5 percent, it is about $1,896 — a savings of roughly $100 a month. Two points cost $6,000 upfront. Divide the cost by the monthly savings and you get the break-even point: $6,000 divided by $100 is 60 months, or five years. If you stay in the house and keep the loan for more than five years, the points save you money. If you sell or refinance before five years, you lost money — you paid $6,000 to save $100 a month for a few years and never got it back. That break-even calculation is the entire decision. Everything else is noise.

Most people underestimate how often they move or refinance. The average homeowner stays in a house about 10 to 13 years, but first-time buyers move sooner, and anyone who buys when rates are high is likely to refinance the moment rates drop. If you buy at 7.5 percent and rates fall to 6 percent in three years, you will refinance — and the points you paid on the first loan are gone. They do not transfer to the new loan. That is the biggest reason points are a bad bet for a lot of buyers: you are paying for a discount on a loan you might not keep long enough to enjoy.

Points also compete with your cash. That $6,000 could go toward a bigger down payment, which lowers your loan amount and your monthly payment permanently — and if it gets you to 20 percent down, it kills private mortgage insurance, which can save you $150 to $250 a month on its own. Or the cash could sit in your emergency fund, which matters a lot in the first year of homeownership, when a broken water heater or a roof leak can cost thousands with no warning. A lower rate is nice. A drained emergency fund in a house you just bought is a problem.

There are situations where points are genuinely smart. If you are buying your forever home, you have a solid emergency fund, you already have 20 percent down, and you plan to stay put for a decade or more, paying for points is one of the cheapest ways to lower your lifetime interest cost. On a $300,000 loan, the difference between 7 percent and 6.5 percent over 30 years is about $36,000 in total interest. You paid $6,000 to save $36,000. That is a great return — as long as you actually stay. Points can also make sense if your credit score is a little weak and the lender is charging you a higher rate; buying the rate down can bring your payment to a level that actually fits your budget.

Watch out for the games lenders play with points. Some quotes bake points into the rate without telling you clearly — the advertised rate looks low because it assumes you pay two points, and the real no-points rate is a quarter or half a point higher. Always ask for the rate with zero points so you are comparing honestly. Get a Loan Estimate from every lender you talk to; it shows the rate, the points, and the total cost side by side, and it is the only way to compare offers without doing the math yourself. And remember that points paid on a primary residence purchase are generally tax-deductible in the year you pay them, which softens the cost a little — but a tax deduction is not a reason to buy points on its own. It just makes the break-even point arrive a few months sooner.

A quick rule of thumb: if your break-even is under five years and you are confident you will stay at least that long, points are worth a serious look. If the break-even is seven years or more, or there is any real chance you move or refinance sooner, keep the cash. The best use of that money is usually the down payment, the emergency fund, or the moving costs you have not budgeted for yet. A lower rate feels good on paper. Cash in the bank feels good when the AC dies in August.
