Frequently Asked Questions
How do I calculate a discount?
Multiply the original price by the discount percentage (as a decimal) to find the discount amount. Then subtract the discount from the original price to get the final price. For example, 25% off $80: discount = $80 × 0.25 = $20, final price = $80 − $20 = $60.
How do I calculate the discount percentage if I know the sale price?
Subtract the sale price from the original price to find the discount amount. Then divide the discount by the original price and multiply by 100. For example, an item marked down from $100 to $75 has a discount of ($100 − $75) / $100 × 100 = 25%.
Can I stack multiple discounts?
When stacking discounts, apply each one sequentially to the reduced price. For example, 20% off then 10% off a $100 item: first discount gives $80, then 10% off $80 gives $72. This is not the same as a single 30% discount ($70).
