About Discount Calculator
Discount maths is simple in principle and easy to get wrong in a shop, especially when offers stack or when tax is applied after the reduction.
This calculator handles all three directions - price after discount, discount from two prices, and stacked offers - and shows the amount you actually save.
Frequently asked questions
How do stacked discounts work?
They multiply rather than add. 20% off then a further 10% off is 28% off in total, not 30%.
Can I work backwards from the sale price?
Yes, enter the original and final price and the tool reports the effective discount percentage.
Is tax included?
Optionally. Add your tax rate and the tool shows the final amount payable after the discount is applied.
