Find the final sale price and how much you save after one or two discounts.
The first discount is taken off the original price, and any extra discount is then applied to that reduced amount, not the original. That is why two 20% discounts are not the same as 40% off. The tool also shows the effective discount so you can compare offers fairly.
Retailers often advertise an extra percentage off an already reduced price. Because the second cut applies to the smaller number, the combined saving is always less than adding the two percentages. This tool shows the true effective discount so a flashy 20 plus 20 does not fool you.
Use the effective discount to line up different deals: a single 35% off can beat a 20% plus 20% stack. Change the numbers to see which promotion actually leaves you paying less at the till.
The final price is what you will pay before any tax or shipping. If your country adds sales tax or VAT at checkout, add that afterwards to know the real total you need in your budget.
The second discount applies to the already-reduced price, so 20% then 20% equals 36% off in total, not 40%.
It is the total percentage you actually saved compared with the original price, after all discounts.
This tool focuses on discounts. For tax, use the VAT calculator to add tax to the final price.
No. Multiplying by both percentages gives the same final price regardless of which discount is applied first.
Yes. Leave the extra discount at zero and it calculates a simple one-step sale price.
