Step by step
- Enter the original price: Type it in Original price and pick your currency.
- Add discounts: Enter a percentage, and use Add another discount for stacked offers.
- Add tax if needed: Enter a percentage in Tax added after discount.
- Read the result: See the final price, your savings and the effective discount.
Handy for
Sales
Check what “extra 10% off sale prices” really means.
Coupons
Combine a store discount and a coupon.
Business quotes
Apply a trade discount and then GST/VAT.
Comparing offers
See which deal gives the lower price.
Good to know
20% + 10% is a 28% discount, not 30%, because the second applies to the reduced price.

Is tax applied before or after the discount?
This tool adds tax after discounts, which is how most receipts work.
