About the discount calculator

How do you calculate a discount?

Multiply the original price by the discount percent divided by 100 to get the amount saved, then subtract that from the original price to get the sale price. For example, 25% off $80 saves 0.25 × 80 = $20, so the sale price is 80 − 20 = $60.

What is the formula for sale price?

Sale price = original price × (1 − discount ÷ 100). The amount you save = original price × discount ÷ 100.

How do I find the original price before a discount?

Divide the sale price by (1 − discount ÷ 100). For example, if an item costs $60 after 25% off, the original price was 60 ÷ 0.75 = $80.
