A discount point is an upfront fee paid at closing, calculated as a share of the loan amount. In exchange, your lender lowers the interest rate on your note, which reduces your monthly payment for as long as you keep the loan. Think of it as prepaying interest now to pay less interest later. Lenders also offer the reverse, called lender credits, which trade a slightly higher rate for money applied toward your closing costs. Neither option is automatically better, and the right answer depends on what you are trying to accomplish.

The most useful question is how long it takes for your monthly savings to repay the upfront cost. Take the amount you paid for points, divide it by the monthly reduction in your payment, and you have a rough break-even month. If you sell or refinance before you reach that point, you have paid more than you saved. Borrowers who expect to stay in the home for many years usually come out ahead, while those who think they may move in a few years often do not. I always suggest a side-by-side comparison showing the same loan with and without points so the math is on paper.

Cash matters as much as the math. If paying points would leave you short for moving costs, furniture, or an emergency fund, the lower payment is not worth the strain. Rates remain elevated compared with the period many buyers grew up with, which is exactly why buydowns deserve a serious look. A lower rate stays in place regardless of where the market moves afterward, which is a different kind of protection than locking a rate alone. Tax treatment varies by situation, so confirm the details with a tax professional before you count on any deduction.
