Mortgage discount points are optional fees you pay at closing to receive a lower interest rate. One point costs 1% of the loan amount, but the rate reduction is not fixed—it depends on the lender, loan program and market pricing that day.
Paying points can make sense when the monthly savings recover the upfront cost before you expect to sell, refinance or pay off the loan. If you may move or refinance sooner, keeping the cash or choosing zero points may be the better decision. The right answer comes from comparing written loan options and calculating the break-even point.
Mortgage Discount Points: Quick Takeaways
- One discount point equals 1% of the mortgage amount. On a $400,000 loan, one point costs $4,000.
- Points lower the interest rate, but one point does not always reduce it by the same amount.
- Break-even months equal the upfront cost of the points divided by the monthly principal-and-interest savings.
- Compare zero-point and point options on the same day, for the same loan type and lock period.
How Do Mortgage Discount Points Work?
Mortgage points are a form of prepaid interest. You pay more at closing in exchange for a lower note rate and a smaller monthly principal-and-interest payment. Discount points are generally optional. They are different from other closing costs and from origination charges that compensate a lender or broker for arranging and processing the loan.
You can often buy a fraction of a point, such as 0.5 or 1.25 points. The price of a point is easy to calculate, but its effect on the mortgage rate varies. Market conditions, the loan program, property type, occupancy, credit profile and lender pricing can all change the result. That is why a blanket promise that one point always lowers the rate by 0.25 percentage points can be misleading.
Because points are fees tied to loan pricing, paying points can reduce the interest rate and lower monthly mortgage payments. Purchasing mortgage points should make financial sense for your timeline—not simply produce the lowest advertised mortgage interest rate.
Understanding how mortgage points work helps you avoid upfront fees that never break even. A fixed rate mortgage with points may lower your interest rate for the life of the loan, but higher monthly payments with zero points may save money if you refinance soon. The breakeven point should match how long you plan to keep the mortgage.
How Much Does One Discount Point Cost?
Multiply the loan amount by the number of points expressed as a percentage:
Loan amount × points percentage = cost of discount points
- 0.5 point on a $400,000 mortgage costs $2,000.
- 1 point on a $400,000 mortgage costs $4,000.
- 2 points on a $400,000 mortgage cost $8,000.
The cost is based on the loan amount, not the home’s purchase price. Points normally appear in the loan-cost section of the Loan Estimate so you can see both the fee and the interest rate associated with it.
Zero, One or Two Points: A Realistic Comparison
The following example compares three hypothetical 30-year fixed-rate options on a $400,000 loan. It assumes that each point lowers the rate by 0.25 percentage points. Actual pricing may be different, so use the table to understand the method—not as a current rate quote.
| Option | Upfront point cost | Example rate | Monthly principal and interest | Monthly savings vs. zero points | Approximate break-even |
|---|---|---|---|---|---|
| Zero points | $0 | 6.75% | $2,594 | — | Immediate |
| One point | $4,000 | 6.50% | $2,528 | $66 | About 61 months |
| Two points | $8,000 | 6.25% | $2,463 | $131 | About 61 months |
These payments exclude property taxes, homeowners insurance, mortgage insurance and association dues. Those expenses do not change simply because you buy discount points.
How to Calculate the Break-Even Point
The break-even point tells you how long it takes for monthly savings to repay the upfront cost:
Cost of discount points ÷ monthly payment savings = months to break even
Using the one-point example above, divide the $4,000 cost by about $66 in monthly savings. The result is roughly 61 months, or just over five years. If you keep that exact mortgage longer than five years, the lower payment begins producing net savings after the break-even point. If you sell or refinance after three years, you would not recover the full cost through monthly savings.
Run the calculation with the actual rates and costs on your Loan Estimates. For additional payment scenarios, use The Mortgage Architects’ mortgage and refinance calculators. A calculator is a starting point; Nathan can compare the complete offers and explain what changes when the loan amount, term or point structure changes.
When Is Buying Mortgage Points Worth It?
Buying mortgage points may be worth considering when you have enough cash to cover the points without draining emergency savings, expect to keep the mortgage beyond the break-even date and value a lower required payment. Points may also help when a slightly lower rate is important to the long-term budget or to qualifying for the desired loan amount.
The strongest case usually combines a reasonable break-even period with a high likelihood that you will keep the loan. The weakest case is paying a large fee for a small rate reduction when you may move, refinance or pay off the mortgage soon.
When Zero Points May Be Better
- You expect to sell or refinance before reaching the break-even point.
- Cash is more valuable for the down payment, reserves, repairs or other closing costs.
- The lender is offering an expensive point structure with limited monthly savings.
- You are comparing an adjustable-rate loan or a short holding period where long-term savings are uncertain.
If you are considering changing an existing loan, read Nathan’s guide on when refinancing makes sense. A future refinance ends the savings from the old rate, so its timing belongs in today’s points decision.
Discount Points vs. Origination Points and Lender Credits
Discount points buy down the interest rate. Origination charges cover services involved in creating the loan; they do not necessarily reduce the rate. The word “point” can be used for either type of charge, so read the Loan Estimate carefully and ask what each fee accomplishes.
Lender credits work in the opposite direction from discount points. You accept a higher interest rate and receive a credit that can offset eligible closing costs. This is sometimes called negative points or a no-point option. It can be useful when minimizing cash at closing matters more than obtaining the lowest possible rate.
How to Compare Mortgage Offers With Points
Do not compare interest rates alone. Ask each lender or mortgage broker to price the same mortgage loan, loan amount, program, lock period and point level on the same day. Review the Loan Estimate for lender charges, origination fees and total loan costs. Then compare:
- Interest rate and annual percentage rate (APR)
- Dollar cost of discount points and origination charges
- Monthly principal-and-interest payment
- Total cash needed at closing
- Five-year cost and break-even month
- Whether a lender credit is included
A lower rate is not automatically the less expensive loan. The best option is the one that fits your expected timeline and financial priorities. A mortgage broker can compare pricing from multiple lenders and explain why one structure may be better for you. Learn more in our mortgage broker vs. bank guide.
Are Mortgage Discount Points Tax-Deductible?
Discount points may qualify as tax-deductible prepaid mortgage interest in some situations, but the timing and eligibility rules depend on how the loan and property are used. Purchase and refinance points may be treated differently. You generally must itemize deductions to receive a benefit. Internal Revenue Service rules can change, so keep your closing documents and ask a qualified tax advisor how the rules apply to you.
Frequently Asked Questions
Discount points are optional closing fees paid to obtain a lower mortgage interest rate. One point costs 1% of the loan amount. The rate reduction attached to that point varies by lender and market conditions.
There is no guaranteed reduction. One point might lower a quoted rate by about 0.25 percentage points in some scenarios, but it can be more or less. Compare the lender’s zero-point and one-point quotes to see the actual tradeoff.
Multiply the mortgage amount by the points percentage. One point on a $300,000 loan costs $3,000; two points cost $6,000. Then divide that cost by the monthly savings to estimate the break-even period.
A seller may be able to contribute toward eligible closing costs, including discount points, subject to the loan program’s contribution limits and the terms of the purchase contract. Your loan officer can confirm the rules for your transaction.
Yes, discount points may be available on a refinance. Include the points and all other closing costs in the break-even calculation. If you may refinance again or sell before recovering those costs, a lower-point option may be safer.
No. A down payment reduces the amount you borrow. Discount points are separate closing costs paid to lower the interest rate on that borrowed amount.
