Discount points are upfront fees paid to lower your interest rate.
1 point = 1% of your loan amount.
Each point typically reduces your rate by 0.25% (varies by lender).
Points are paid at closing and may be tax-deductible.
Consider buying points if:
• You'll stay in the home beyond the break-even period
• You have extra cash and want lower monthly payments
• Rates are expected to rise (refinancing later would cost more)
Avoid points if: You may move or refinance soon

5. Example Calculation
Scenario:
Loan: $400,000
Base Rate: 6.75%
1 Point Cost: $4,000 (1%)
Rate Reduction: 0.25% per point
Term: 30 years
Plan to stay: 10 years
Results:
Monthly Payment:
No points: $2,594
1 point (6.5%): $2,528
Monthly Savings: $66
Break-Even:
$4,000 ÷ $66 = 60.6 months (~5 years)
10-Year Savings:
Total savings: $7,920 (120 × $66)
Minus points cost: $3,920 net saved
