Calculate Percentages Now →Understanding the Basics of Percentage
A percentage represents a part of a whole, expressed as a fraction of 100. The word "percent" means "per hundred." So, 25% means 25 out of every 100. Knowing this basic definition is the foundation for understanding how to calculate percentages effectively.
Common Percentage Problems and How to Solve Them
Most percentage problems fall into one of three categories:
- Finding a percentage of a number: What is X% of Y? (e.g., What is 15% of 200?)
- Finding what percentage one number is of another: X is what percent of Y? (e.g., 30 is what percent of 150?)
- Calculating percentage increase or decrease: What is the percentage change from X to Y? (e.g., What is the percentage change from 80 to 100?)
Manual Calculation Methods
While a calculator can be a huge help, it is good to know how to calculate percentage manually too.
- Finding X% of Y: Convert X% to a decimal (divide by 100) and multiply by Y. For example, 15% of 200 is (15/100) * 200 = 0.15 * 200 = 30.
- Finding X is what percent of Y: Divide X by Y and multiply by 100. For example, 30 is what percent of 150 is (30/150) * 100 = 0.2 * 100 = 20%.
- Calculating percentage change: Use the formula [(New Value - Old Value) / Old Value] * 100. For example, the percentage change from 80 to 100 is [(100 - 80) / 80] * 100 = (20/80) * 100 = 25%.
