About Discount Calculator
Stacked discounts do not add up. Thirty percent off followed by another twenty percent is not fifty percent off — the second discount applies to the already reduced price, giving 44% off in total. Retailers rely on that gap being unintuitive.
Tax is normally applied after discounts, so a coupon reduces the tax you pay as well as the price. This calculator follows that order, which is what nearly every checkout does.
Frequently asked questions
- Why is 30% then 20% not 50% off?
- The second discount applies to the reduced price, so the combined effect is 44% off.
- Is tax applied before or after the discount?
- After. Discounts reduce the taxable amount, which is how most checkouts work.
- Can I enter a fixed amount off?
- Yes, switch the discount type from percentage to amount.
