Mortgage Discount Points Calculator: Should You Buy Down Your Rate?
When you're closing on a mortgage, your lender may offer you the option to "buy down" your interest rate by purchasing **discount points**. But is it worth paying thousands of dollars upfront to save a fraction of a percent on your interest rate? Our **Discount Points Calculator** helps you make this critical financial decision.
What Are Mortgage Discount Points?
A discount point is a one-time fee you pay at closing to lower your mortgage interest rate. Each point typically costs **1% of the loan amount** and usually reduces your rate by approximately **0.25%** (though this varies by lender).
Example: On a $300,000 loan, one point costs $3,000 and might lower your rate from 7.0% to 6.75%.
How to Calculate the Break-Even Point
The key question is: "How long will it take for my monthly savings to equal the upfront cost?"
Formula: Break-Even Months = Cost of Points ÷ Monthly Savings
Example Calculation
- Loan Amount: $300,000
- Original Rate: 7.0% (monthly payment: ~$1,996)
- New Rate with 1 point: 6.75% (monthly payment: ~$1,946)
- Monthly Savings: $50
- Cost of 1 Point: $3,000
- Break-Even: 3,000 ÷ 50 = 60 months (5 years)
If you plan to stay in the home for more than 5 years, buying the point saves you money. If you move or refinance before then, you lose money.
When Buying Points Makes Sense
- You plan to stay long-term: The longer you keep the mortgage, the more you save.
- You have cash available: Points require upfront cash at closing. If depleting your savings leaves you with no emergency fund, it's risky.
- Rates are high: When rates are elevated, a small reduction has a bigger impact on your monthly payment.
- You can't deduct PMI: If you're putting less than 20% down, buying points might save more than PMI costs you.
When to Skip the Points
- You plan to move soon: If you sell or refinance before the break-even point, you've wasted money.
- Cash is tight: Your down payment and closing costs are already stretching your budget.
- Rates are falling: If you expect to refinance within a few years as rates drop, paying points now is a waste.
- Investment opportunities: If you could earn more by investing that cash (e.g., retirement accounts, stock market), skip the points.
Tax Deductibility
In the U.S., discount points are generally **tax-deductible** in the year they are paid if the loan is for your primary residence and meets IRS requirements. This can reduce the effective cost of buying points. Consult a tax professional for your specific situation.
Points vs. Origination Fees
Don't confuse discount points with **origination points** (or loan origination fees). Both are expressed as a percentage of the loan, but:
- Discount Points: Buy down your rate
- Origination Fees: Lender profit (don't reduce your rate)
Always ask your lender to clarify which is which.
Conclusion
Buying discount points can save you thousands over the life of your loan—but only if you keep the mortgage long enough to break even. Use our **Discount Points Calculator** to run the numbers and make an informed decision based on your timeline and financial goals.
