Percentage change can be found by:

(Difference ÷ original amount) x 100

For instance, if I purchased a car for £5000 and sold it for £2000

((5000 - 2000) ÷ 5000) x 100

(3000 ÷ 5000) x 100

0.6 x 100

60

Therefore, the percentage loss is 60%

To find the percentage change, you use the following equation:

Final amount - initial amount divided by the initial amount and finally multiplied by 100

This will tell you the percentage increase or decrease

hope that helps!

First find the actual change by subtracting the two values.

Then form a fraction which has the actual change on top and the original value on the bottom.

Simplify the fraction if possible and then convert the fraction to a percentage.

If you are not allowed a calculator to convert the fraction to a percentage, then first convert the fraction to a decimal by dividing the top by the bottom and then multiply the answer by 100 to get the percentage version.

If you are allowed a calculator then just type in the fraction and then multiply by 100, you may need to use the StoD button to get the decimal answer.

Formula - Percentage increase = (increase / original number) x 100

1) Work out the difference between the two numbers being compared, to find the increase.

2) Divide the increase by the original number and multiply the answer by 100.
