When you are shopping for a mortgage, your lender will likely offer you the option to pay "points" upfront in exchange for a lower interest rate. It sounds appealing — pay a little more now to save money every month. But the math does not always work in your favor, and many homebuyers pay for points they never benefit from.
Understanding how mortgage points work — and how to calculate whether they make sense for your situation — can save you thousands of dollars.
What Are Mortgage Points?
A mortgage point (also called a discount point) is equal to 1% of your loan amount. Paying one point on a $300,000 mortgage costs $3,000 upfront. In exchange, the lender reduces your interest rate — typically by 0.25% per point, though this varies by lender and market conditions.
Points are paid at closing and increase your closing costs. They are separate from origination fees, which lenders sometimes also call "points" but which do not reduce your rate. Make sure you understand which type you are being offered.
How to Calculate Your Break-Even Point
The core question when evaluating points is: how long will it take for the monthly savings to recoup the upfront cost? This is your break-even point.
Example: You are borrowing $300,000 at 7.00%. Your lender offers to reduce the rate to 6.75% if you pay 1 point ($3,000 upfront).
- Monthly payment at 7.00% (30-year): approximately $1,996
- Monthly payment at 6.75% (30-year): approximately $1,946
- Monthly savings: $50
- Break-even: $3,000 ÷ $50 = 60 months (5 years)
If you stay in the home and keep the mortgage for more than 5 years, the points pay off. If you sell, refinance, or pay off the loan before 5 years, you lose money on the points.
When Paying Points Makes Sense
- You plan to stay in the home long-term — well beyond the break-even period
- You have excess cash at closing and want to reduce your monthly payment
- You are in a stable rate environment and refinancing in the near term is unlikely
- The lower rate helps you qualify for a larger loan amount you otherwise couldn't access
- You are on a fixed income or have a tight monthly budget where lower payments matter more than upfront costs
When to Skip the Points
- Your break-even period is longer than 5–7 years and you are uncertain about your plans
- You could put those upfront dollars to better use — paying down higher-interest debt, funding an emergency reserve, or investing
- You expect to refinance within a few years if rates drop
- You are stretching to cover closing costs and need to preserve cash
Negative Points — When the Lender Pays You
The opposite of discount points also exists. With negative points (also called lender credits), the lender pays some of your closing costs in exchange for a higher interest rate. This makes sense if you are short on cash at closing, plan to sell or refinance soon, or simply prefer a lower upfront cost even at the price of a slightly higher monthly payment.
Are Points Tax Deductible?
Mortgage discount points paid on the purchase of your primary residence are generally fully deductible in the year paid, provided you meet IRS requirements. This can reduce the effective cost of buying points for taxpayers who itemize deductions. Points paid on a refinance must typically be deducted over the life of the loan rather than all at once. Consult a tax professional for guidance specific to your situation.
The Bottom Line
Mortgage points are neither universally good nor universally bad — they are a financial tool whose value depends entirely on your specific circumstances. Calculate your break-even period, be honest about how long you plan to stay in the home, and consider the opportunity cost of the upfront cash. When the math works and your plans align, points can be a smart way to reduce your long-term borrowing cost.
