What Are Mortgage Points & How Do They Work?

Mortgage points, also known as discount points, are prepaid interest that you pay upfront at closing to reduce your mortgage interest rate. One point typically costs 1% of your loan amount and lowers your rate by about 0.25% (varies by lender). The break-even point is when the monthly savings from the lower rate equal the upfront cost. If you stay in the home beyond that period, buying points saves you money. Our mortgage points break-even calculator shows you exactly when you start saving.

When Does Buying Points Make Sense?

  • Long-term ownership: If you plan to stay beyond the break-even point, points are cost-effective.
  • Low cash flow needs: You have extra savings to invest in lower monthly payments.
  • Tax advantages: Points are often tax-deductible in the year of purchase (consult a tax advisor).
  • Lower rates without refinancing: A permanent rate buydown reduces payments for the entire loan term.

Use this mortgage points savings calculator to test different scenarios and see if points align with your financial goals.

Real-Life Example: Points vs. No Points

Scenario: $300,000 loan, 30-year term. Without points: 6.5% rate → monthly P&I = $1,896. With 1 point ($3,000 cost) → new rate 6.25% → monthly P&I = $1,847. Monthly savings = $49. Break-even months = $3,000 / $49 ≈ 61 months (about 5 years). If you stay 7+ years, buying points saves you money. This mortgage rate buydown calculator gives you the exact numbers for your situation.

Frequently Asked Questions About Mortgage Points

❓ Is it better to buy points or put more down payment?

It depends. A larger down payment reduces loan amount and may eliminate PMI, while points lower your rate. Use our calculator to compare long-term costs; sometimes a combination works best.

❓ How much do points lower my interest rate?

Typically, one point lowers the rate by 0.25% (25 basis points), but it varies by lender, loan type, and market. Our tool lets you manually set the after-points rate for accuracy.

❓ Are mortgage points tax deductible?

In many cases, points paid on a primary residence are fully deductible in the year paid, provided certain IRS criteria are met. Consult a tax professional for your situation.

❓ What's the break-even point for buying points?

Break-even is the number of months it takes for the monthly savings to offset the upfront cost. Our mortgage points break-even calculator instantly computes this for your inputs.
