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.
