How successive discounts are calculated

Successive discounts don't add up: each discount is applied to the price already reduced by the previous one, so the real total discount is smaller than the sum of the percentages.

final price = price × (1 − d1/100) × (1 − d2/100) × (1 − d3/100)

Worked example

A 200 € product with 20% and then 10% off: final price = 200 × 0.80 × 0.90 = 144 €. The real total discount is 28%, not 30%.

Frequently asked questions

Why isn't the total discount the sum of the percentages?
Because each discount is applied to an already reduced price, not to the original price, so the combined effect is smaller than a simple sum.
Can I use just one or two discounts?
Yes, leave the remaining discount fields at 0 if you only want to apply one or two.
Does the order of the discounts matter?
The mathematical result is the same regardless of the order in which the successive discounts are applied.
