How discount points work

A point is prepaid interest: you pay 1% of the loan at closing and the lender lowers your rate for the life of the loan. Your break-even is the point cost divided by the monthly saving. The highlighted row in the table is the option that leaves you best off at the horizon you entered.

Points are one way to spend cash at closing. Putting the same money toward a larger down payment, or toward avoiding PMI, sometimes beats them. And if you expect rates to fall and plan to refinance, points you buy today are wasted when you do. On a refinance, points count toward closing costs in the break-even calculator.

Questions people ask

How much does one mortgage point cost?
One point costs 1% of the loan amount: $3,600 on a $360,000 loan. Points are paid at closing and appear on page 2 of the Loan Estimate as a percentage of the loan amount.
How much does a point lower the rate?
It varies by lender and market. A common range is about 0.125 to 0.25 percentage points per point. Always get the exact rate for each point option from the lender in writing rather than assuming.
When are mortgage points worth it?
When you keep the loan past the break-even month. If you might sell or refinance within a few years, skipping points (or even taking lender credits) is usually cheaper.
Are mortgage points tax deductible?
For a home purchase, points are often deductible in the year paid if you itemize. On a refinance, the IRS generally requires them to be deducted over the life of the loan. IRS Publication 936 has the rules.
