How to calculate the percentage from a number

Calculating a percentage might seem tricky at first, but it's actually quite simple! Let's learn how to do it step by step.

Step 1: What is a Percentage?

Think of a percentage as a way to show parts of a whole. It's like dividing something into smaller pieces to understand how much each part is.

Step 2: Understanding 1%

1% is 1 hundredth of the whole.

Imagine you have 100 LEGO blocks. 1% would be like having just 1 of those blocks.

  • 100/100 = 1

If you have 500 LEGO blocks. 1% would be like having just 5 of those blocks.

  • 500/100 = 5

Step 3: Turning Percentages into Fractions

Let's say we want to find out what 10% of a number is. We can turn that percentage into a fraction. A fraction is just a way to represent a part of a whole.

  • 10% becomes 10 out of every 100, which is written as 10/100.

Step 4: Multiply to Find the Percentage

To find out what 10% of a number is, you multiply that number by the fraction we just made (10/100).

  • For example, if the number is 50, then you do:
    • 50 · (10/100) = 5

Calculate percentage of a number Formula

A% of B = A100 × B

e.g. 3% of 200 = 3100 × 200 = 6

Calculate percentage of a number in Excel or Google Sheets
