Growth Rate = [(New Value – Old Value) / Old Value] × 100
Subtract the old value from the new value
Divide the result by the old value
Multiply by 100 to get the percentage
If the result is positive, it indicates growth
If the result is negative, it indicates decline
Example: [(150 – 100) / 100] × 100 = 50%
Example: [(80 – 100) / 100] × 100 = -20%
