How to Calculate Percentage
If you wonder how do I calculate percentage of a number, here’s a quick guide:
Case 1: Calculate the Percentage
To find the percentage, use this basic formula:
Percentage = (Value / Total Value) × 100
For example, if the value is 20 and the total value is 50, then:
- Calculation: (20 / 50) × 100 = 40%
- Meaning: 20 is 40% of 50.
Case 2: Calculate the Value from a Given Percentage
Sometimes you know the percentage and the total value, and you want to find the value. Rearrange the formula as:
Value = (Percentage / 100) × Total Value
For example, if you want to find 30% of 200, then:
- Calculation: (30 / 100) × 200 = 60
- Meaning: 30% of 200 is 60.
Case 3: Calculate the Total Value from a Given Percentage
If you know the value and the percentage, you can find the total value using:
Total Value = Value ÷ (Percentage / 100)
For example, if 30 is 15% of a total value, then:
- Calculation: 30 ÷ (15 / 100) = 30 ÷ 0.15 = 200
- Meaning: The total value is 200.
