FAQs
How do I calculate a discount?
Multiply the original price by the discount percentage, then subtract the discount amount from the original price.
Is 20% off plus 10% off the same as 30% off?
Not usually. Sequential discounts are applied one after another, so the final savings are smaller than simply adding percentages.
Why is the checkout total different?
Tax, shipping, fees, coupons, and rounding can change the final checkout amount.
Can I calculate the original price from a sale price?
Yes, if you know the discount percentage, you can work backward to estimate the original price.
