Questions
Frequently asked questions
Is 30% + 10% the same as 40% off?
No. The 10% applies to the already-reduced price, so the real discount is 37%.
How do I find the original price from the sale price?
Divide the sale price by (1 − discount/100). A $75 item at 25% off was $100.
Is tax charged before or after discount?
Usually after the discount, which is how this calculator works.
