Percentage off calculates the sale price: Original × (1 − discount/100). A 20% discount on $50 = $50 × 0.80 = $40, saving $10. For stacked discounts (20% then 10% off), apply sequentially — NOT by adding percentages. 20% then 10% off ≠ 30% off!
How to Use
Enter price and discount:
- Original: Starting price
- Discount: Percentage off
- Result: Sale price and savings
Stacking Discounts
20% off then 10% off: $100 → $80 → $72. That's 28% total, NOT 30%. Order doesn't matter for stacked percentages, but the total is always less than the sum.
Tax After Discount
Tax is applied AFTER the discount. $100 item, 20% off, 8% tax: $100 → $80 → $80 × 1.08 = $86.40.
