Frequently Asked Questions
How do I calculate 20% off $50?
20% of $50 is $10 (50 × 0.20). The sale price would be $40 ($50 - $10).
How do I find the original price after discount?
If you know the sale price and discount percentage: Original Price = Sale Price ÷ (1 - Discount Percentage/100). For example, if an item is $80 after 20% discount: $80 ÷ 0.8 = $100 original price.

Discount amount is the actual dollar value saved (e.g., $20 off), while discount percentage is the relative saving expressed as a percentage of the original price (e.g., 20% off).
How do I calculate multiple discounts?
For multiple discounts (e.g., 20% off then 10% off), apply them sequentially to the reduced price: First discount: $100 × 0.8 = $80. Second discount: $80 × 0.9 = $72. Total discount is 28% from original.
Understanding Discounts
What is a Discount?
A discount is a reduction in the original price of a product or service. It is usually expressed as a percentage of the original price and is commonly used in shopping, retail, promotions, and sales. Discounts help customers save money and can be used by businesses to attract buyers.
Example: 20% off a $200 item means you pay $160.
Basic Discount Formulas
Discount Amount:
Discount = (Original Price × Discount % ÷ 100)
Example: 15% of $200 = 200 × 0.15 = $30
Sale Price:
Sale Price = Original Price − Discount Amount
Example: 200 − 30 = $170
Discount % from Sale Price:
Discount % = ((Original − Sale) ÷ Original) × 100
Example: (200 − 170) ÷ 200 × 100 = 15%
