Why is a 20% rise then a 20% fall not even?
The fall is taken from the larger number: 100 up 20% is 120, and 120 down 20% is 96.

0How it’s calculated
- Percent of a number = percent ÷ 100 × number
- What percent = part ÷ whole × 100
- Percent change = (new − old) ÷ old × 100
Example: 20% of 150 is 30. 30 is 20% of 150. Going from 150 to 180 is a 20% increase.
