How Do Mortgage Points Work and Are They Worth It?

By Homecrest Guide Editorial Team · September 28, 2026

Learn how mortgage points work, how much they cost, and how to calculate your break-even period before paying for a lower rate on a DC home loan.

When you’re shopping for a mortgage in Washington, DC, lenders will often offer you the option to pay extra upfront in exchange for a lower interest rate. This is called buying mortgage points, and on a large DC loan, the math can either save you thousands of dollars or lock up cash you’d have been better off keeping. The right answer depends almost entirely on how long you plan to keep the loan.

Quick answer: one discount point typically costs 1% of your loan amount and lowers your rate by roughly 0.25%, though the exact amount varies by lender and market conditions. Points may make sense when you expect to keep the mortgage long enough for the monthly savings to recover the upfront cost. If you expect to sell or refinance before that break-even point, paying points may provide less value.

What mortgage points actually are

A mortgage point (or «discount point») is a fee you pay the lender at closing in exchange for a lower interest rate on your loan. It’s a way of prepaying interest upfront to reduce the interest you pay over time.

• Cost: 1 point = 1% of your loan amount. On a $500,000 loan, one point costs $5,000.
• Effect: commonly reduces your rate by about 0.125% to 0.375% per point, though this varies by lender, loan type and market pricing at the time.
• Points are listed on your Loan Estimate and Closing Disclosure, so you can compare offers with and without them side by side.

Discount points vs origination points

These two terms are often confused, but they serve different purposes:

• Discount points buy down your interest rate. They’re optional, and the cost and benefit are usually clearly disclosed.
• Origination points (or origination fees) are a charge from the lender for processing the loan. They do not lower your interest rate; they are simply a cost of obtaining the loan

When reviewing Loan Estimates, check whether an advertised interest rate requires discount points, since this can change your upfront costs. Compare the total cost of each offer, not just the quoted terms.

Real break-even calculation on a DC-sized loan

Here’s an illustrative example on a $550,000 loan. Actual point pricing varies by lender and day, so use this as a framework, not a quote.

Break-even calculation:

Break-even (months) = Cost of points ÷ Monthly savings

• 1 point: $5,500 ÷ $92 = about 60 months (5 years)
• 2 points: $11,000 ÷ $182 = about 60 months (5 years)

In this example, you’d need to keep the loan for about 5 years before the points pay for themselves. If you sell or refinance before then, you lose money on the points. If you keep the loan longer, you come out ahead, and the savings continue to grow every month after break-even.

When mortgage points make sense

• Plan to stay in the home well past the break-even point. This is the single most important factor.
• Make sure you have enough cash available without depleting your emergency fund or down payment. Never pay points at the expense of a healthy cash reserve, especially with DC’s higher cost of living.
• Consider your expectations for future rates. If you believe rates could fall enough to make refinancing attractive, the upfront cost of points may be less appealing.
• Prioritize your other financial goals first, such as retirement contributions or paying off high-interest debt, so purchasing points remains an optional use of extra cash.

When mortgage points don’t make sense

• Selling or refinancing within the break-even window may make paying points less attractive — for example, because of a known job relocation, a starter home you plan to outgrow, or an ARM you intend to refinance out of before adjustment.
• Limited cash for your down payment or closing costs can also make points less appealing. In DC’s expensive market, keeping more cash for reserves or the down payment itself may be more valuable than securing a slightly lower rate.
• Expectations of falling interest rates may also affect the decision. If you plan to refinance regardless, the upfront cost of points could provide less value.
• High-interest debt should also be considered. Paying off credit cards or other expensive debt may be a higher priority than reducing your mortgage rate.

Negative points (lender credits)

Some lenders offer the opposite of points: a lender credit, sometimes called negative points, where you accept a higher rate in exchange for a credit toward your closing costs.

This can make sense if:

• You’re short on cash for closing costs but have room in your monthly budget for a slightly higher payment.
• You plan to refinance soon anyway, so a higher rate for a short period costs less than paying points or full closing costs upfront.

As with points, compare the total cost over your expected time in the loan, not just the upfront cash difference.

How to decide if points are worth it for you

1. Get the break-even number in writing from your lender for each point option, along with the loan estimate.
2. Be honest about your time horizon. If you’re not fairly confident you’ll keep the loan past break-even, skip the points.
3. Protect your cash reserves first. Points should come from truly discretionary cash, not your safety net.
4. Compare points against other uses of the same money, such as a larger down payment (which can remove PMI) or paying off higher-interest debt.
5. Re-run the math if your rate or loan amount changes during underwriting, since the break-even period shifts with both.

Next steps

• Ask every lender you compare for rate options with zero, one and two points, along with the exact break-even period.
• Decide your realistic time horizon in the home before you shop for a rate.
• Compare the points decision against your down payment and PMI strategy as a package, not separately.
• Use our DC Mortgage Payment Calculator to test how different rates change your monthly payment.

Frequently asked questions

Are mortgage points tax deductible? Discount points may be deductible in the year paid or over the life of the loan, depending on your situation and whether you itemize deductions. Rules and limits apply, so confirm your specific case with a tax professional.

How much does one mortgage point cost? One point typically costs 1% of your loan amount. On a $500,000 loan, that’s $5,000, though exact pricing depends on the lender and market conditions that day.

Is it better to put more money down or buy points? It depends on your goals. A larger down payment reduces your loan amount and can remove PMI; points lower your rate on the loan you already have. Ask your lender to model both scenarios side by side before deciding.

Can I negotiate mortgage points with my lender? Point pricing reflects market rate sheets more than individual negotiation, but you can and should shop multiple lenders, since their point pricing and fees can differ meaningfully for the same rate.

What happens to unused points if I refinance early? You simply don’t recoup the remaining value of the points you paid; there’s no refund. This is exactly why the break-even calculation matters before you decide to pay for points.
