How to use
- Enter the original price and currency, then choose percentage or fixed discount.
- Enter the first discount and an optional additional percentage for a coupon or second sale.
- Read the discounted price, savings and effective discount rate.
How it works
After a percentage discount: price × (1 − rate ÷ 100). After a fixed discount: price − amount. An additional discount is applied to the already discounted price.
Common questions
Do 20% and 10% add up to 30%?
No. The second discount applies to the reduced price, so the effective discount in this example is 28%.
Can a fixed discount exceed the price?
No. Fixed discounts must be no more than the original price so the final price cannot become negative.
Are tax and shipping included?
Only the entered price is calculated. Include tax or shipping in that amount first if you want them covered.
