Have you ever needed to calculate the difference between two numbers? It's a fundamental skill in many areas of life, from balancing your budget to understanding statistics. But sometimes, simple subtraction isn't enough. You might need to know the absolute difference or express the difference as a percentage.

Calculate the Difference Now →Calculating the Basic Difference
The most straightforward way to find the difference between two numbers is to subtract one from the other. However, this gives you a signed difference (positive or negative), indicating direction. For example:
- 5 - 3 = 2
- 3 - 5 = -2
The result depends on the order of subtraction. But what if you only care about the magnitude of the difference, not the direction?
Absolute Difference: Focusing on Magnitude
The absolute difference gives you the magnitude of the difference, regardless of sign. It's calculated by subtracting the numbers and then taking the absolute value:
Absolute Difference = |Number 1 - Number 2|
Using our previous example:
- |5 - 3| = |2| = 2
- |3 - 5| = |-2| = 2
Now, the result is always positive. This is useful when you want to know how far apart two numbers are, without caring which one is larger.
Percentage Difference: A Relative Comparison
Sometimes, understanding the difference as a percentage is more meaningful. This allows you to compare differences relative to the size of the numbers involved. The formula for percentage difference is:
Percentage Difference = (|Number 1 - Number 2| / ((Number 1 + Number 2) / 2)) * 100
Let's calculate the percentage difference between 5 and 3:
(|5 - 3| / ((5 + 3) / 2)) * 100 = (2 / 4) * 100 = 50%
This tells you that the numbers differ by 50% relative to their average.
Percentage Change: Measuring Growth or Decline
Percentage change is used to express how much a quantity has increased or decreased. It’s calculated as follows:
Percentage Change = ((New Value - Old Value) / Old Value) * 100
For example, if a stock price goes from $80 to $100, the percentage change is:
((100 - 80) / 80) * 100 = 25%
This indicates a 25% increase in the stock price. This is different than finding the percentage of a number
Let Our Calculator Do the Work
While understanding these formulas is valuable, calculating them manually can be time-consuming and error-prone. That's where our percentage calculator comes in! It can quickly and accurately solve these problems for you:
- Find what percent of a number is: Quickly determine values such as what is 15% of 200.
- Figure out what percentage one number is of another: Understand ratios, such as 30 is what percent of 150.
- Calculate percentage change: Easily see how much something increased or decreased, like going from 80 to 100.
Our calculator works on both your phone and computer, allowing you to solve percentage problems whenever and wherever you need to.
