Follow three successive price changes
Start at 100 · −20% · +10% · −5%
- 01
100 × 0.8 = 80.
- 02
80 × 1.1 = 88.
- 03
88 × 0.95 = 83.6.
- 04
Overall change: (83.6 − 100) ÷ 100 × 100 = −16.4%.
The final value is 83.6, down 16.4% overall.
Illustrative example · Rates compound on each new value. Adding −20 + 10 − 5 would give the wrong overall change.
