Discount calculator FAQ

Is 20% off then 10% off the same as 30% off?

No. Applied successively, they produce an equivalent discount of 28%.

When is sales tax applied?

This calculator applies tax to the discounted sale price.

How do I find the original discount percent?

Subtract sale price from original price, divide by original price, then multiply by 100.

Can a fixed discount exceed the original price?

Yes, but the result becomes negative. Check the entered amount when a negative price is not intended.
