Discount Points Calculator
Discount Points Calculator
When you apply for a mortgage, you may be offered the option to purchase discount points. These points are an upfront fee you pay to your lender at closing in exchange for a reduced interest rate on your loan.
While buying discount points can save you thousands of dollars over the life of a mortgage, they also require a larger upfront investment. This makes it important to carefully calculate whether purchasing points is worth it for your financial situation.
The Discount Points Calculator is a simple tool that helps homeowners and buyers compare the cost of buying points with the potential long-term savings.
What Are Discount Points?
A discount point is essentially prepaid interest.
- 1 discount point = 1% of your total loan amount.
- Each point usually reduces your mortgage rate by 0.25% (though this may vary by lender).
For example:
- Loan amount = $200,000
- 1 discount point = $2,000
- If the interest rate drops from 6.5% to 6.25%, you’ll save on monthly payments.
Why Do Lenders Offer Discount Points?
Discount points benefit both lenders and borrowers:
- Lenders get guaranteed upfront income.
- Borrowers get a lower interest rate and reduced long-term costs.
The trade-off is deciding whether the initial expense is worth the future savings.
What is a Discount Points Calculator?
The Discount Points Calculator helps you determine:
- How much discount points will cost upfront.
- How much your monthly mortgage payment will decrease.
- Your break-even point (how long it takes for savings to cover the upfront cost).
- Total lifetime savings if you keep the loan long enough.
This ensures you make a well-informed financial decision.
Formula Behind the Calculator
The basic calculations involve:
- Cost of Points:
Cost of Points=Loan Amount×Points Percentage\text{Cost of Points} = \text{Loan Amount} \times \text{Points Percentage}Cost of Points=Loan Amount×Points Percentage
- New Interest Rate:
New Rate=Original Rate−(Number of Points×Rate Reduction per Point)\text{New Rate} = \text{Original Rate} – (\text{Number of Points} \times \text{Rate Reduction per Point})New Rate=Original Rate−(Number of Points×Rate Reduction per Point)
- Monthly Payment Calculation (using standard mortgage formula):
M=P×r(1+r)n(1+r)n−1M = P \times \frac{r(1+r)^n}{(1+r)^n – 1}M=P×(1+r)n−1r(1+r)n
Where:
- MMM = Monthly payment
- PPP = Loan amount
- rrr = Monthly interest rate
- nnn = Loan term in months
- Break-Even Period:
Break-Even (Months)=Cost of PointsMonthly Savings\text{Break-Even (Months)} = \frac{\text{Cost of Points}}{\text{Monthly Savings}}Break-Even (Months)=Monthly SavingsCost of Points

Real-Life Examples
Example 1 – Single Discount Point
- Loan: $250,000
- Interest Rate: 6.5%
- Buying 1 point ($2,500) lowers rate to 6.25%.
- Monthly savings: ~$40.
- Break-even: $2,500 ÷ $40 ≈ 63 months (5 years, 3 months).
- If you stay longer than 5 years, it’s worth it.
Example 2 – Multiple Points
- Loan: $300,000
- Rate: 7%
- Buy 2 points ($6,000). New rate: 6.5%.
- Monthly savings: ~$95.
- Break-even: $6,000 ÷ $95 ≈ 63 months (5 years, 3 months).
Example 3 – Short-Term Homeowner
- Loan: $200,000
- Rate: 6%
- Buy 1 point ($2,000). New rate: 5.75%.
- Monthly savings: ~$30.
- Break-even: 67 months (5.6 years).
- If you plan to sell in 3 years, not worth it.
