Mortgage discount points let you pay more at closing for a lower interest rate. They may make sense if you can comfortably afford the upfront cost and expect to keep the same mortgage long enough to recover it through lower monthly payments.
The key question is: How long will it take for the savings to pay back the cost, and does that timeline fit your plans?
What do mortgage discount points cost?
One discount point equals 1% of your loan amount. On a $400,000 mortgage, one point costs $4,000, and half a point costs $2,000. Points can also be quoted in other fractions.
Buying one point does not reduce your interest rate by one percentage point. The rate reduction varies by lender, loan type, borrower qualifications, and market conditions. Ask for the actual rate and dollar cost of each option in writing.
Where to find points in your loan paperwork
Discount points appear in Section A on page 2 of the Loan Estimate and Closing Disclosure. These points must be connected to a reduced interest rate.
Other lender charges, such as origination fees, may also be expressed as a percentage of the loan amount. Ask which fees reduce your rate and which cover other services.
A zero-point mortgage can still have closing costs and lender fees. Compare total upfront loan costs, including any lender credits, alongside the amount charged for points.
How to calculate the break-even point
When other upfront loan costs are the same, use this simple calculation:
Cost of points ÷ monthly principal-and-interest savings = break-even period in months
Suppose you compare two otherwise identical fixed-rate mortgage options. One has no discount points. The other costs $3,200 in points and reduces your monthly principal-and-interest payment by $50.
$3,200 ÷ $50 = 64 months, or five years and four months.
Here is how those savings would look over different timelines:
| Time keeping the mortgage | Cumulative payment savings | Payment savings minus $3,200 point cost |
|---|---|---|
| 3 years | $1,800 | −$1,400 |
| 5 years, 4 months | $3,200 | $0 |
| 8 years | $4,800 | +$1,600 |
This hypothetical illustration assumes the points are paid in cash at closing and monthly savings remain $50. It measures payment savings only; it excludes returns you could earn on that cash, tax effects, and differences in the remaining loan balance. Principal and interest also exclude property taxes, homeowners insurance, and any mortgage insurance.
If lender fees or credits differ between offers, use the difference in upfront loan costs when estimating break-even. A full comparison should also consider the remaining balance when you expect to sell, refinance, or repay the loan.
Consider your timeline and your cash reserves
Think about how long you expect to keep this mortgage, including the possibility of selling, refinancing, or paying it off early. A refinance generally replaces the original loan, so the original payment savings would end. Future refinancing should not be assumed to be available or beneficial.
Compare the shortest, most likely, and longest realistic periods you might keep the loan. Paying points becomes more appealing when your expected timeline extends comfortably beyond break-even.
You also need enough cash after closing for emergencies, moving expenses, repairs, and other household needs. A lower payment may offer less value if paying for it leaves you with too little financial breathing room.
How do lender credits compare?
Lender credits generally offer the opposite tradeoff: you accept a higher interest rate in exchange for a credit toward eligible closing costs. That can preserve cash upfront while increasing your monthly payment and borrowing costs over time.
Some credits are promotions or adjustments unrelated to the rate. Ask how the specific credit affects your pricing, then compare point-paying, zero-point, and lender-credit options across the same timelines.
How to compare mortgage offers
Request options using the same loan amount, loan type, term, down payment, occupancy, and rate-lock period. Compare quotes from the same day when possible, and confirm whether the rates are locked.
For each option, ask for:
- The interest rate, points in dollars, other lender fees, and any lender credits.
- The monthly principal-and-interest payment and estimated total payment.
- The cash needed at closing and how much would remain in your reserves.
- The annual percentage rate, or APR.
- The estimated cost over your likely loan timeline, including the remaining balance.
APR reflects the interest rate plus certain loan charges, including points. It is useful context, but your decision should also account for upfront costs, your expected timeline, and the terms of the loan.
