How to calculate the percentage change

Calculating percentage change is straightforward and useful for understanding how much something has increased or decreased over time. Let's break it down step by step!

Step 1: Understand What Percentage Change Means

Percentage change measures how much something has either grown or shrunk in comparison to its original value. It's like tracking whether the temperature has risen or dropped since the morning!

Step 2: Gather Your Numbers

You need two numbers: the original number (before) and the new number (after). For example:

  • Before: 200 (the original number)
  • After: 150 (the new number)

Step 3: Find the Difference

To calculate how much the number has changed, subtract the original number from the new number:

Difference=After - Before

In this example: Difference=150 - 200=-50

Step 4: Calculate the Percentage Change

Now, divide the difference by the original number and multiply by 100 to find the percentage change:

Percentage Change=(Difference / Before) * 100%

For this example: Percentage Change=(-50 / 200) * 100%=-25%

Step 5: Interpret the Result

A negative percentage (-25%) means the number has decreased by 25%. A positive percentage would indicate growth or increase, whereas a negative percentage shows a decrease or reduction.

Let's Recap:

  • Percentage Change shows how much something has increased or decreased compared to its original value.
  • Gather Your Numbers: Before and After.
  • Find the Difference: Subtract Before from After.
  • Calculate the Percentage Change: Divide the Difference by Before and multiply by 100.
  • Interpret the Result: A positive result means growth, while a negative result indicates a decrease.
