How to Calculate Discounts
1. Percentage Discount
Formula: Discount Amount = Original Price x (Discount % / 100)
Example: 20% off $100 = $100 x (20/100) = $20 discount, Final Price = $80
2. Fixed Amount Discount
Formula: Final Price = Original Price - Discount Amount
Example: $15 off $100 = $100 - $15 = $85 Final Price
3. Stacked Discounts
When applying multiple discounts, each discount is applied to the price after the previous discount.
Example: 20% off then 10% off on $100:
First discount: $100 x 0.80 = $80
Second discount: $80 x 0.90 = $72 Final Price
Common Discount Percentages
- 10% off - Multiply by 0.90
- 20% off - Multiply by 0.80
- 25% off - Multiply by 0.75 (1/4 off)
- 50% off - Multiply by 0.50 (half price)
- 75% off - Multiply by 0.25 (3/4 off)
