How to Calculate Percentages Manually
Although our calculator performs every calculation instantly, understanding the basic formulas can help you learn the concept.
Formula 1 – Find a Percentage of a Number
To calculate a percentage of any value:
- Divide the percentage by 100.
- Multiply the result by the total number.
Formula
Result = (Percentage ÷ 100) × Value
Example
20% of 80
= 20 ÷ 100 × 80
= 16
Formula 2 – Find What Percentage One Number Is
To determine what percentage one number represents of another:
- Divide the smaller value by the larger value.
- Multiply by 100.
Formula
Percentage = (Part ÷ Whole) × 100
Example
15 is what percent of 60?
15 ÷ 60 × 100
= 25%
Formula 3 – Calculate Percentage Increase or Decrease
To calculate percentage change:
- Find the difference between the new value and the original value.
- Divide that difference by the original value.
- Multiply by 100.
Formula
Percentage Change = ((New Value − Original Value) ÷ Original Value) × 100
A positive result means an increase.
A negative result means a decrease.
