About this calculator
Work out the price after a discount, how much you save and the final price with tax. A second discount can be added after the first, as many shops do with an extra coupon.
How it works
- Price after discount is the price times (1 minus the discount divided by 100).
- A second discount is taken off the already discounted price, so 20% then 10% is 28% off, not 30%.
- Tax is added to the discounted price.
Common questions
Why is 20% plus 10% not 30% off?
The second discount applies to a smaller price. 100 becomes 80 after 20%, then 72 after 10%, which is 28% off in total.
Is tax added before or after the discount?
Here it is added after, which is how most shops charge it. Rules differ by country, so check yours.
