Calculate 20% Now →The Basic Formula
The easiest way to calculate 20% of a number is to use the following formula:
20% of X = (20/100) * X
Where X is the number you want to find 20% of.
Step-by-Step Calculation
- Convert the percentage to a decimal: Divide 20 by 100, which gives you 0.20.
- Multiply the number by the decimal: Multiply the original number (X) by 0.20.
Examples
- What is 20% of 50?
0. 20 * 50 = 10
So, 20% of 50 is 10.
- What is 20% of 150?
0. 20 * 150 = 30
Therefore, 20% of 150 is 30.
- What is 20% of 300?
0. 20 * 300 = 60
Thus, 20% of 300 is 60.
Alternative Methods
- Finding 10% and doubling it: First, calculate 10% of the number by dividing it by 10. Then, double the result to get 20%.
- Using Fractions: Recognize that 20% is equivalent to 1/5. Therefore, you can find 20% of a number by dividing it by 5.

- Tipping: Quickly calculating a 20% tip at a restaurant.
