Calculate Percentages Instantly →Three Common Percentage Problems
Most percentage calculations fall into one of three categories:
- Finding a percentage of a number: What is P% of X? (e.g., What is 15% of 200?)
- Finding what percentage one number is of another: Y is what percent of X? (e.g., 30 is what percent of 150?)
- Calculating percentage increase or decrease: What is the percentage change from A to B? (e.g., What is the percentage change from 80 to 100?)
Using a Basic Calculator
Even without a dedicated "%" key, you can still use a basic calculator:
Finding a Percentage of a Number
- Convert the percentage to a decimal by dividing it by 100. For example, 15% becomes 0.15.
- Multiply the number by the decimal. For example, 200 * 0.15 = 30.
- Therefore, 15% of 200 is 30.
Finding What Percentage One Number Is of Another
- Divide the first number (Y) by the second number (X). For example, 30 / 150 = 0.2.
- Multiply the result by 100 to express it as a percentage. For example, 0.2 * 100 = 20%.
- Therefore, 30 is 20% of 150.
Calculating Percentage Increase or Decrease
- Find the difference between the new value (B) and the original value (A). For example, 100 - 80 = 20.
- Divide the difference by the original value (A). For example, 20 / 80 = 0.25.
- Multiply the result by 100 to express it as a percentage. For example, 0.25 * 100 = 25%.
- Therefore, the percentage increase from 80 to 100 is 25%.
