How to use

Three discount modes

"Price after discount" calculates the sale price from original price and percentage off. "What % off?" calculates the discount percentage from original and sale price. "Original price" works backwards from a sale price to find what the original was.

💡 Did you know?

'70% off' and '50% off plus an extra 40% off the sale price' aren't the same. The latter is actually 70% off (0.5 × 0.6 = 0.3, so 30% of original = 70% off). Stacked percentages multiply, they don't add.
