Calculate Percentages Instantly →The Basic Percentage Formula
At its core, finding a percentage of a number involves a simple formula:
Percentage = (Part / Whole) × 100
This formula helps you determine what portion of a whole a particular part represents, expressed as a percentage.
Types of Percentage Problems Solved
This formula can be manipulated to solve three common types of percentage problems:
- 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: From X to Y, what is the percentage change? (e.g., Going from 80 to 100 is what percentage increase?)
Sound complicated? Don't worry! Our intuitive calculator handles all these variations with ease. Simply input the values you know, and let it do the rest! Also, related articles can be found at Calculate Percentage Calculator and Work out Percentage of Two Numbers.
Breaking Down the Formulas
Let's look at each type of problem in detail:
1. Finding a Percentage of a Number
Formula: Y = (P/100) * X
Where:
- Y = The result you're trying to find
- P = The percentage
- X = The original number
Example: What is 20% of 50?
Y = (20/100) * 50 = 10
2. Finding What Percentage One Number Is of Another
Formula: P = (Y / X) * 100
Where:
- P = The percentage you're trying to find
- Y = The part
- X = The whole
Example: 10 is what percent of 50?
P = (10 / 50) * 100 = 20%
3. Calculating Percentage Increase or Decrease
Formula for Increase: Percentage Increase = ((New Value - Original Value) / Original Value) * 100
Formula for Decrease: Percentage Decrease = ((Original Value - New Value) / Original Value) * 100
Where:
- New Value = The updated value
- Original Value = The initial value
Example Increase: What is the percentage increase from 50 to 60?
Percentage Increase = ((60 - 50) / 50) * 100 = 20%
Example Decrease: What is the percentage decrease from 60 to 50?
Percentage Decrease = ((60 - 50) / 60) * 100 = 16.67%
