Frequently Asked Questions
How do I calculate a discount? +
Multiply the original price by the discount percentage, then subtract. For example, 20% off $50: $50 x 0.20 = $10 off, so you pay $40.
How do I find the original price from a sale price? +
Use the "Find Original Price" mode. If you paid $80 after 20% off, the original was $80 / (1 - 0.20) = $100.
Can I calculate stacked discounts? +
This handles single discounts. For stacked discounts, apply the first, then use the result as the new price for the second discount.
