Frequently asked questions

How do I calculate a discount?

Multiply the original price by the discount percentage (as a decimal): sale price = original × (1 − discount/100). For a 25% discount on $120: $120 × 0.75 = $90.

How do I find the original price from a sale price?

Divide the sale price by (1 − discount/100). If an item costs $90 after a 25% discount: $90 ÷ 0.75 = $120.

How do I calculate what percentage off I got?

Divide the savings by the original price and multiply by 100: discount% = ((original − sale) ÷ original) × 100.

What is the difference between discount and markdown?

A discount is a reduction from the listed price, often for promotions or loyalty. A markdown is a permanent price reduction, typically to clear inventory. Mathematically, the calculation is identical.
