How to find the Percentage increase

Take a look at the 3 easy steps below for finding how to find the percentage increase or decrease between 2 numbers.

Step 1) Subtract the original number from the new number.

Step 2) Divide this number by the original number.

Step 3) Multiply this number by 100 to convert it to a percentage.

If the number is negative, then it is a percentage decrease, if it is positive then it is an increase.

Examples

Example 1) A long jumper jumps 720cm on his first jump and 756cm on his 2nd jump. Work out the percentage increase.

Step 1) 756 - 720 = 36cm

Step 2) 36 ÷ 720 = 0.05

Step 3) 0.05 x 100 = 5%

Answer: there is a 5% increase in his jump length.

Example 2) I buy a bike for $350. I sell the bike for $270 after six months. What was my percentage loss in price to 1 decimal place?

Step 1) 270 - 350 = -80

Step 2) -80 ÷ 350 = -0.22857...

Step 3) -0.22857 x 100 = 22.857% or 22.9% to 1dp

Answer: there is a 22.9% decrease or loss in price.
