How Discount Calculation Works
Percentage Discount
For percentage discounts, the formula is:
Discount Amount = Original Price × (Discount % ÷ 100)
Sale Price = Original Price - Discount Amount
Sale Price = Original Price - Discount Amount
Example: $100 with 20% discount = $100 × 0.20 = $20 discount, $80 sale price.
Multiple Discounts
Multiple discounts are applied sequentially, not additively:
Price₁ = Original × (1 - Discount₁%)
Price₂ = Price₁ × (1 - Discount₂%)
And so on...
Price₂ = Price₁ × (1 - Discount₂%)
And so on...
Example: $100 with 20% then 10% = $100 × 0.8 × 0.9 = $72 (not $70).
