Discount Calculator
MathWork out a sale price, the amount saved, or the discount percent from any one of them, and stack successive discounts correctly
Enter an original price plus any one of the discount percent, the amount off, or the final price, and the other two are solved for you. The second mode is the one most discount calculators skip: stacking several discounts in sequence, where each one comes off the already-reduced price. That is why 20% off followed by an extra 10% off is a 28% discount and not 30%, a gap this tool shows step by step so you can check a promotion before it goes live. Everything is plain arithmetic on the numbers you type, with no tax, shipping, or currency conversion mixed in.

- 2.Read the final price, the amount saved, and the effective discount percent from the result cards. Solved fields are highlighted.
- 3.Switch to Stacked discounts and type a comma-separated list like 20, 10 to apply several discounts in order and see the true combined discount.
Frequently asked questions
Why is 20% off then 10% off not 30% off?
The second discount applies to the already-reduced price, not the original. 20% leaves 80% of the price, then 10% off that leaves 72%, an effective 28% discount.
Does this include sales tax or VAT?
No. This is the sticker-price calculation only. Use the VAT / Sales Tax Calculator to add or remove tax before or after the discount.
What currency does it use?
None. Amounts are plain numbers, so enter them in whatever currency or unit you like and the results come back in the same one.
Why does it reject a final price higher than the original?
That is a price increase rather than a discount, and silently returning a negative discount tends to hide a typo. Use the Percentage Change Calculator for increases.
