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 a percentage
If the result is positive, it is growth
If the result is negative, it is a decline
For compound annual growth rate, use: CAGR = [(Ending Value / Beginning Value)^(1 / Number of Years)] – 1
Multiply CAGR by 100 to express it as a percentage
