How to Calculate

Sale Price = Original Price × (1 - Discount/100)

Where Original Price = the initial price before discount, Discount = the percentage discount to apply. Subtract the discount percentage from 100 and multiply by the original price.

Frequently Asked Questions

How do I calculate a discount?
Multiply the original price by the discount percentage (as a decimal), then subtract from the original price. For example, 20% off $50: $50 × 0.20 = $10 discount, so the sale price is $50 - $10 = $40.
How do I calculate the original price from a sale price?
Divide the sale price by (1 - discount rate). For example, if an item costs $40 after a 20% discount: $40 ÷ (1 - 0.20) = $40 ÷ 0.80 = $50 original price.
