The percentage change result = 40%

Calculation [(7-5) / 5] x 100% = 0.4 x 100% = 40%

Formula of calculating the percentage change

Percentage Change = (V new – V old) / V old x 100%, which means that they percentage change from the old to new value is computed by; the difference between the new and old values which is divided by the old value. The result is then multiplied by 100 percent.

For example
Determine the percentage increase from $1500 to $2500.

Solution
Initial Value = 1500

Final value = 2500

Percentage change = (2500 - 1500) / 1500 x 100%

= 1000/1500 x 100%

=0.666 x 100%

=66.67%
