Percentage Calculation Formula
The basic formula used for calculating percentages is:
I1 × I2 = P
Where:
- I1 = First input value
- I2 = Second input value
- P = Resultant percentage
Example
If:
- P × 50 = 2
Then:
- P = 2 ÷ 50
- P = 0.04 × 100
- P = 4%
Percentage Difference Formula
The percentage difference measures how much one value changes relative to another.
Percentage Increase Example
If a value of 700 increases by 20% (0.2):
700 × (1 + 0.2) = 840
Percentage Decrease Example
If a value of 700 decreases by 20% (0.2):
700 × (1 − 0.2) = 560
