Calculate Percentages Instantly! →Three Common Percentage Problems
Percentages are used in many different contexts. Here are three common problems involving percentages:
- Finding a percentage of a number: What is X% of Y? (e.g., What is 15% of 200?)
- Determining 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: From X to Y, what is the percentage change? (e.g., Going from 80 to 100 is what percentage increase?)
Calculating "X is What Percent of Y?"
This is perhaps the most common type of percentage calculation. Here's the formula:
Percentage = (X / Y) * 100
Let's break it down with an example:
Example:
You scored 75 out of 100 on a test. What percentage did you score?
- Identify X and Y: X = 75 (your score), Y = 100 (total possible score).
- Apply the formula: Percentage = (75 / 100) * 100
- Calculate: Percentage = 0.75 * 100 = 75%
Therefore, you scored 75% on the test.
Calculating Percentage Increase or Decrease
This calculation determines the percentage change between two values. The formula is:
Percentage Change = ((New Value - Old Value) / Old Value) * 100
Example:
A product's price increased from $50 to $60. What is the percentage increase?
- Identify New Value and Old Value: New Value = $60, Old Value = $50.
- Apply the formula: Percentage Change = (($60 - $50) / $50) * 100
- Calculate: Percentage Change = ($10 / $50) * 100 = 0.2 * 100 = 20%
Therefore, the product's price increased by 20%.

Our tool handles all three types of percentage problems: finding a percentage of a number, determining what percentage one number is of another, and calculating percentage increase or decrease. It's designed for quick and accurate results whether you're at home or on the go. Understanding basic percentage calculations are still crucial for everyday problem solving.
Understanding Percentage Difference
It's important to note the difference between percentage change and percentage difference. Percentage change measures the change from an initial value to a final value, relative to the initial value. Percentage difference, on the other hand, compares two values without regard to which is "initial" or "final." It is calculated as:
Percentage Difference = (|Value 1 - Value 2| / ((Value 1 + Value 2) / 2)) * 100
The key distinction is that percentage change implies a direction (increase or decrease), while percentage difference simply expresses the relative difference between two numbers.
Conclusion
Knowing how to figure out percentage between two numbers is a valuable skill for many aspects of life. With the formulas and explanations provided, you can confidently tackle percentage problems. And for quick and accurate calculations, remember that our percentage calculator is always available to simplify the process.
