💡 Stacking Discounts
Two successive discounts are NOT additive. A 20% off followed by another 10% off equals 28% total, not 30%. Always calculate compound discounts: Final = Price × (1 – d1) × (1 – d2).
🛍️ How to Calculate Discounts
Sale Price from % Off
Sale Price = Original Price × (1 - Discount% / 100)
Example: $100 item, 30% off → $100 × 0.70 = $70
Find Discount Percentage
Discount % = ((Original - Sale) / Original) × 100
Example: $100 → $75 → ((100-75)/100) × 100 = 25%
Find Original Price
Original Price = Sale Price / (1 - Discount% / 100)
Example: Sale $60 after 25% off → $60 / 0.75 = $80 original

❓ Frequently Asked Questions
How do I calculate price after discount? +
Sale Price = Original Price × (1 – Discount% / 100). For $80 with 25% off: $80 × 0.75 = $60.
How do I find the discount percentage? +
Discount % = ((Original – Sale) / Original) × 100. If $100 item sells for $75: ((100-75)/100) × 100 = 25%.
How do I find the original price from a sale price? +
Original = Sale Price / (1 – Discount% / 100). If $60 after 25% off: $60 / 0.75 = $80 original.
Do two 50% discounts equal 100% off? +
No! Two 50% discounts = 75% total off. First 50% off $100 = $50. Then 50% off $50 = $25. The discounts multiply, not add.
