Understanding the Basics

Before diving into calculations, let's cover some fundamental concepts:

  • Percentage: A way of expressing a number as a fraction of 100. The term "percent" comes from the Latin "per centum," meaning "by the hundred."
  • The Percent Symbol (%): This symbol simply means "divided by 100." So, 25% is the same as 25/100.
  • Common Conversions:
    • 50% = 1/2 = 0.5
    • 25% = 1/4 = 0.25
    • 10% = 1/10 = 0.1

Three Common Percentage Problems, Solved Instantly!

Our percentage calculator tackles these three common scenarios with ease:

1. Finding What Percent of a Number Is

This is the classic "What is X% of Y?" problem. For example, what is 15% of 200?

Formula: (Percentage / 100) * Number

Example: (15 / 100) * 200 = 30

Quick Solution: Enter 15 and 200 into the PercentageFinder.org calculator. The answer is 30!

2. Determining the Percentage One Number Is of Another

This solves "X is what percent of Y?" For instance, 30 is what percent of 150?

Formula: (Part / Whole) * 100

Example: (30 / 150) * 100 = 20%

Fast Answer: Input 30 and 150 into our percentage calculator, and you'll see that 30 is 20% of 150.

3. Calculating Percentage Increase or Decrease

This helps you determine the percentage change between two values. What is the percentage increase from 80 to 100?

Formula: ((New Value - Original Value) / Original Value) * 100

Example: ((100 - 80) / 80) * 100 = 25%

Instant Result: Let the percentage calculator do the work! Just enter 80 and 100, and you'll find the increase is 25%.

Percentage Formulas Explained

While our calculator is super convenient, understanding the underlying formulas can be helpful. Here's a breakdown:

  • Finding P percent of X: The basic formula here is: Y = P% * X. Remember to convert P% to a decimal before you do the calculation!
  • Finding what percent of X is Y: The basic formula is: P% = Y/X. Don't forget to multiply by 100 to get the final percentage number.
  • Finding X if P percent of it is Y: The basic formula here is: X = Y / P%. Remember to convert the percentage to a decimal (by dividing by 100) before you do the calculation.
