About Discount
Discount works out what you actually pay after a percentage off, plus how much you saved, with optional sales tax applied afterwards. Shops quote the percentage, not the number that matters — this converts "30% off" into the figure that leaves your account.
How to use it
- Enter the original price and the discount percentage.
- Add a tax rate if one applies — it is calculated on the discounted price, which is how it normally works.
- Read the final amount and the saving.
Questions
How do I handle "50% off, then 20% off"?
Run the tool twice. Stacked discounts multiply rather than add: 50% then 20% is 60% off in total, not 70%.
Is tax applied before or after the discount?
After, in almost every jurisdiction — you are taxed on what you actually pay. That is what this tool does.
How do I work out the percentage from two prices?
Use the Percentage tool in "% change" mode with the original and sale prices.
