Are Mortgage Discount Points Worth It? 2026 Breakeven Guide

When closing on a home mortgage, lenders frequently offer borrowers the option to purchase discount points (often called "buying down the rate"). In exchange for paying an upfront fee at closing, the lender permanently lowers the interest rate on your mortgage note.

With 30-year fixed mortgage rates hovering between 6.5% and 7.25% in 2026, many homebuyers wonder: Is paying thousands of dollars in upfront cash worth a fraction of a percent in interest rate reduction?

The answer comes down to one core mathematical calculation: Your Break-Even Horizon.

1. What Are Mortgage Discount Points?

A mortgage discount point is a form of prepaid interest.

  • Cost: Exactly 1.0% of the loan amount per point.
  • On a $300,000 loan, 1 point costs $3,000.
  • On a $500,000 loan, 1 point costs $5,000.
  • On an $800,000 loan, 1 point costs $8,000.
  • Benefit: In the current US mortgage market, 1 point typically reduces your interest rate by 0.25% (25 basis points). Depending on lender rate sheets and market volatility, the buydown ratio can fluctuate between 0.125% and 0.375% per point.

2. The Simple Break-Even Formula

The standard metric used by mortgage brokers and financial planners is the Simple Break-Even Period:


Break-Even Period (Months) = Upfront Cost of Points ÷ Monthly Payment Savings

Worked Example:

Suppose you borrow $400,000 on a 30-year fixed mortgage:

  • Original Rate: 7.00% → Monthly Principal & Interest (P&I) = $2,661.21
  • Points Purchased: 1.0 point ($4,000 upfront)
  • Reduced Rate (7.00% - 0.25%): 6.75% → Monthly P&I = $2,594.30
  • Monthly Savings: $2,661.21 - $2,594.30 = $66.91 / month

Now calculate the break-even:


Break-Even Months = $4,000 ÷ $66.91 = 59.8 Months (approx. 5.0 Years)

The Golden Rule:

  • If you keep this loan for less than 60 months (5.0 years), buying points is a net financial loss.
  • If you keep this loan for more than 60 months, every subsequent month represents pure financial profit. Over the full 30-year term, you will pocket $20,087.60 in net interest savings ($24,087.60 gross savings minus $4,000 cost).

3. The Number One Risk: The Refinance Trap

Why doesn't every homebuyer buy discount points? The single biggest threat to discount points is the early move or refinance.

According to national data from the Federal Housing Finance Agency (FHFA) and Freddie Mac, the median American homeowner keeps their mortgage for only 5 to 7 years before either:

  1. Selling the home to relocate or upsize.
  2. Refinancing the mortgage when interest rates drop.

What Happens If You Refinance Early?

If you pay $4,000 for 1 point today, but mortgage rates drop by 1.5% in 3 years (Month 36) and you refinance into a lower rate:

  • Total savings accumulated in 36 months: 36 × $66.91 = $2,408.76.
  • Upfront points fee paid: $4,000.00.
  • Net Loss: -$1,591.24.

You spent $4,000 to save $2,409. The remaining unrecovered $1,591 is gone forever.

4. Opportunity Cost: The Investment Alternative

When calculating break-even, sophisticated investors also evaluate opportunity cost. If you have an extra $4,000 at closing, what else could you do with that cash?

  • If you deposit $4,000 into a High-Yield Savings Account (HYSA) or Treasury bill earning 5.0% APY, that $4,000 will grow to $5,105 over 5 years.
  • If you instead spend the $4,000 on points, you forfeit that compound growth.
  • Factoring in compound growth pushes the true opportunity-cost break-even out to 68–74 months (5.7–6.2 years).

5. When Should You Buy Mortgage Points?

Buying Points Makes Sense If:

  1. You are buying your "forever home": You have zero intention of moving for at least 7 to 10 years.
  2. Mortgage rates are already historic lows: If rates are at generational lows, the probability of refinancing later is minimal.
  3. The seller offers closing credits: If the seller or builder offers seller concessions (e.g. $5,000 in closing cost credits) that cannot be applied to the down payment, using seller funds to buy down the interest rate is free savings for you!

Avoid Buying Points If:

  1. You plan to move within 3–5 years: Starter homes or temporary job assignments rarely stay past the breakeven mark.
  2. Rates are elevated and likely to decline: If you anticipate refinancing within 2 to 3 years when the Federal Reserve eases monetary policy, keep your cash in reserve.
  3. You are cash-constrained at closing: Never drain your emergency savings or home maintenance reserves just to buy discount points.
