The Break-Even Point: When Buying Mortgage Points Actually Saves You Money

When a lender offers you a mortgage, they will almost always give you a choice between paying a higher interest rate with lower upfront costs, or a lower interest rate if you pay extra money at closing. Those extra upfront dollars are called mortgage points. One point equals one percent of your total loan amount. So on a $400,000 mortgage, one point would cost you $4,000. In return, the lender will usually lower your interest rate by roughly a quarter of a percent, though the exact amount can vary between lenders.

The main reason homeowners consider buying points is simple. You pay money now to have lower monthly payments for as long as you live in the house. But the real question every homeowner needs to answer is whether that trade-off is actually worth it. The key to making that decision is understanding something called the break-even point.

The break-even point is the amount of time it will take for your monthly savings from the lower interest rate to add up to the upfront cost you paid for the points. Once you pass that date, you are officially saving money. If you sell or refinance before you hit that date, then you actually lost money by buying points because you never got enough reduced payments to cover what you paid at closing.

To figure out your own break-even point, you need two numbers. The first is how much the points cost you at closing. The second is how much your monthly payment drops because of the lower rate. Divide the first number by the second number, and that gives you the number of months until you break even.

For example, imagine you are borrowing $300,000. One lender offers you a rate of seven percent with no points. Another lender offers you a rate of six point five percent if you pay two points, which costs you $6,000. Your monthly principal and interest payment at seven percent is roughly $1,996. At six point five percent, it drops to about $1,896. That is a savings of $100 per month. Divide your $6,000 cost by the $100 monthly savings, and you get sixty months. That is five years. If you plan to stay in that home for more than five years, buying those points will put money back in your pocket. If you plan to move in four years, you would be better off skipping the points and taking the higher rate.

It is important to remember that the break-even point assumes your loan payment stays the same. If you make extra principal payments or refinance again before you hit break-even, the math changes. Also, many homeowners get distracted by that monthly savings number without doing the full calculation. Saving one hundred dollars a month sounds great until you realize it took five years just to get your $6,000 back.

Another factor that matters a great deal is your available cash at closing. Buying points means you need to bring more money to the table on top of your down payment, closing costs, and prepaid items. If that extra cash would leave you with very little emergency savings, the risk might not be worth it. A lower payment does not help you if you cannot afford an unexpected plumbing repair or a job loss.

The market environment also plays a role. When interest rates are high overall, buying points can be more attractive because the monthly savings are larger. But when rates are low, the benefit of buying points shrinks because you cannot lower your rate very much further. You also need to consider the possibility that rates will drop in the future. If you think you might refinance in two years anyway, paying points now would be a waste because you would lose that upfront investment when you replace the loan.

Many borrowers also overlook the fact that points are tax deductible as mortgage interest in the year you buy the home, but not every homeowner benefits from that deduction. You can only deduct it if you itemize your taxes, and the deduction is phased out for higher income earners. So do not assume the tax break will make a big difference.

Ultimately, buying mortgage points is a bet on how long you will keep the loan. It is a simple prepayment of future interest. If you win the bet and stay past break-even, you come out ahead. If you lose the bet and leave early, you paid money for nothing. The smartest approach is to get rate quotes from your lender both with and without points, run your own break-even calculation based on your honest plan for how long you will be in the house, and then make the choice that fits your finances and your future.
