How to calculate discount?

To calculate a discount, multiply the original price by the discount percentage (converted to a decimal) to find the amount saved. Then, subtract that savings amount from the original price to get the final sale price.

Formula

Savings = Original Price × (Discount % ÷ 100) Final Price = Original Price − Savings

Worked Example

A $100 item is 20% off.

1. Find Savings: $100 × 0.20 = $20
2. Find Price: $100 − $20 = $80

Result: The discounted price is $80.
