A percentage is a way to express a number as a fraction of 100. It's a ratio that tells us how much of something we have relative to a whole. The symbol "%" is used to denote percentages. For example, 25% means 25 out of 100.
Percentages are used everywhere, from calculating discounts at the store to understanding financial reports. Being able to quickly calculate percentages is a valuable skill. Here’s a breakdown of common percentage problems and how our calculator can help:
Common Percentage Problems Solved Instantly
Our calculator handles these three main types of percentage calculations:
- Finding a Percentage of a Number: What is X% of Y? For example, what is 15% of 200? This is useful for figuring out discounts, tips, or the amount of tax you owe.
- Figuring Out Percentage of One Number to Another: X is what percent of Y? For example, 30 is what percent of 150? This is helpful for understanding proportions, like how much of your budget goes to rent.
- Calculating Percentage Increase or Decrease: From X to Y, what's the percentage change? For example, going from 80 to 100 is what percentage increase? This is useful for tracking growth, whether it's sales, weight loss, or website traffic.

How the Percentage Formula Works
While our calculator does the heavy lifting, understanding the underlying formula can be helpful. The basic percentage formula is:
Percentage = (Part / Whole) * 100
Depending on what you're trying to find, you can rearrange this formula:
- To find the Part: Part = (Percentage / 100) * Whole
- To find the Whole: Whole = Part / (Percentage / 100)
- To find the Percentage: Percentage = (Part / Whole) * 100
Manual Calculation Example
Let's say you want to find what percentage 30 is of 150. Here's how to do it manually:
- Identify the Part and the Whole: Part = 30, Whole = 150
- Apply the formula: Percentage = (30 / 150) * 100
- Calculate: Percentage = 0.2 * 100 = 20%
Therefore, 30 is 20% of 150. Our calculator automates this process, so you don't have to worry about the math!
