How it is calculated
- Each discount applies to the already reduced price.
- Final price = price × (1 − d1 ÷ 100) × (1 − d2 ÷ 100) × …
- Total discount = (price − final price) ÷ price × 100.
Example
100 with −20%, −10% and −5%: 100 × 0.8 × 0.9 × 0.95 = 68.40, i.e. −31.6% (not −35%).
Good to know
- Each discount must be between 0 and 100%.
- The order of percentage discounts does not change the final price.
