How to find the Percentage Increase (Calculator 1)

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

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

How to find the Percentage Increase (Calculator 2)

Take a look at the 3 easy steps below to find how to increase or decrease a number by a given percentage.

Step 1) If the percentage is a percentage increase, then add the percentage to 100% to find the total percentage.

If the percentage is a decrease then work out 100 subtract the given percentage to find the total percentage.

Step 2) Divide the total percentage by 100 to convert it to a decimal.

Step 3) Multiply the original number by this decimal to find your answer.

Examples

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

  • We are trying to find the percentage increase between two numbers, so we can use calculator 1 to solve this problem.

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 have $3400 in a bank account. After a year it has increased by 7%. How much do I have now?

  • We need to find the answer after a percentage increase, so we need calculator 2 to solve this problem.

Step 1) 100% + 7% = 107%

Step 2) Convert 107% into a decimal: 107 ÷ 100 = 1.07

Step 3) Multiply the original number by the decimal.

3400 x 1.07 = 3638

Answer: I now have $3638.


Example 3) 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?

  • We are trying to find the percentage decrease between two numbers, so we need calculator 1.

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.


Example 4) A bike is priced at $120. It is reduced by 15% in a sale. How much would it cost now?

  • We need to find the answer after a percentage decrease, so we need calculator 2.

Step 1) 100% - 15% = 85%

Step 2) Convert 85% into a decimal: 85 ÷ 100 = 0.85

Step 3) Multiply the original number by the decimal.

120 x 0.85 = 102

Answer: The bike is on sale for $102.
