Formula and rules
- Percentage off: first discount = price × percentage ÷ 100
- Fixed amount off: first discount = the amount you type, capped at the price
- Extra percentage applies to the already discounted price, not the original price
- Effective discount = total saved ÷ original price × 100
Worked examples
80 less 25, then another 10%
Input Price 80, fixed amount off 25, extra percentage 10%.
Result The fixed discount leaves 55.00, the extra 10% takes 5.50 more, so you pay 49.50 and save 30.50 — an effective 38.13% off.
FAQ
Do two 20% discounts equal 40% off?
No. The second 20% applies to the reduced price, so you pay 80% × 80% = 64% of the original, which is a 36% total discount rather than 40%. The effective discount output shows the combined figure.
Why can the effective discount be different from the percentage I entered?
Fixed-amount discounts and stacked coupons change the maths. A 25 discount on an 80 item is 31.25%, and adding an extra percentage pushes the combined rate higher still.
What if the fixed discount is larger than the price?
The first discount is capped at the price, so the item becomes free instead of producing a negative price. Any extra percentage then has nothing left to reduce.
