Should You Buy Mortgage Discount Points? Complete Guide

When shopping for a mortgage, you'll often encounter discount points as an option to reduce your interest rate. But are they actually worth the upfront cost? This guide explains what discount points are, how they work, and provides a free calculator to determine whether buying points makes financial sense for your specific situation.

What Are Mortgage Discount Points?

Mortgage discount points are upfront fees you pay at closing to permanently lower your interest rate. Each point costs 1% of your total loan amount and typically reduces your rate by approximately 0.25% (though this varies by lender).

Example: On a $300,000 loan, one point costs $3,000. Buying one point might reduce your rate from 4.0% to 3.75%. Two points would cost $6,000 and could reduce your rate to 3.5%.

Points are also called "mortgage discount points," "discount points," or "origination points," depending on the context. They're different from origination fees - points specifically reduce your interest rate.

How Much Do Discount Points Cost?

The cost is straightforward: one point = 1% of your loan amount.

• $200,000 loan: 1 point = $2,000
• $300,000 loan: 1 point = $3,000
• $400,000 loan: 1 point = $4,000

You can buy partial points (0.5, 0.75, etc.), and most lenders allow you to purchase up to 4 points per loan. The rate reduction per point typically ranges from 0.20% to 0.25%, but confirm the exact reduction with your lender.

Why Buy Discount Points?

Discount points make sense in these scenarios:

• Long-term ownership: If you plan to stay 7+ years, the monthly savings often exceed the upfront cost.
• Positive breakeven: When your monthly payment reduction will offset the point cost before you plan to leave.
• Lower monthly payments: Points reduce your payment immediately, helping with qualification or budget.
• Tax deduction: Points paid at closing may be tax-deductible if certain IRS conditions are met. Consult a tax professional.
• Building equity faster: Lower rates mean more of each payment goes toward principal.

When to Avoid Discount Points

Skip points if:

• Short ownership: Selling within 5-7 years (breakeven rarely occurs sooner)
• Limited closing funds: Cash shortages for down payment or other closing costs
• Uncertain plans: Unsure if you'll refinance or relocate soon
• Weak cash flow: Monthly savings don't matter if you can't afford the upfront cost

Understanding Your Breakeven Point

The breakeven point is how many months until the monthly savings equal your upfront cost. For example:

Scenario: You pay $4,000 for one point and save $50/month on your payment.

Breakeven: $4,000 ÷ $50 = 80 months (6.7 years)

If you plan to keep your home longer than 6.7 years, you profit. If you plan to sell in 5 years, you lose money. Use the calculator above to find your exact breakeven time based on your loan details.

Discount Points vs. Other Rate-Reduction Options

Before buying points, explore alternatives:

• Larger down payment: 5% more down often qualifies you for a better rate without paying points
• Improve credit score: 50+ point jump can reduce your rate significantly
• Shop multiple lenders: Rates vary; better offers exist without points
• Wait and refinance: If rates drop later, refinance instead of paying points now

Are Discount Points Tax-Deductible?

In some cases, yes. Points paid at closing on a primary residence or second home may be deductible in the year paid if they:

• Are clearly itemized on your Closing Disclosure
• Represent the standard practice in your area
• Are paid with your own funds (not borrowed money)

Important: Tax rules vary. Consult a CPA or tax professional to confirm eligibility for your situation.

How to Use the Discount Points Calculator

1. Enter loan amount: Total mortgage balance
2. Select current rate: Your quoted interest rate
3. Choose points: How many you're considering (0-4)
4. Pick loan term: 10, 15, 20, 25, 30, or 40 years
5. Enter planned years: How long you'll keep the loan
6. Calculate: Instantly see monthly savings, cost, breakeven, and total interest savings

The calculator compares your payment with and without points, calculates when you break even, and shows whether points are worth buying based on your timeline.

Real-World Example

Scenario: $350,000 loan, 4.25% rate, 30-year term, planning to stay 10 years

Option A (No points): Payment = $1,722/month

Option B (Buy 1.5 points):

• Points cost: $5,250 (1.5% of $350,000)
• New rate: 3.75%
• New payment: $1,623/month
• Monthly savings: $99
• Breakeven: 53 months (4.4 years)
• 10-year savings: $11,880 - $5,250 = $6,630 net benefit

In this case, buying 1.5 points makes financial sense because you break even in under 5 years and have 5+ years of profit remaining.

Final Thoughts

Discount points can save you significant money if you own your home long enough to reach breakeven. However, they're not universally beneficial - short-term owners, cash-strapped buyers, and those with uncertain plans should skip them.
