Calculating a percentage increase might sound tricky, but it's actually quite simple! Let's learn how to do it step by step.
A percentage increase tells us how much something has grown or gotten bigger compared to its original size. It's like measuring how much a plant has grown after watering it!
You'll need two numbers: the original number (before) and the new number (after). For example:
To find out how much the number increased, subtract the original number from the new number:
Difference = After - Before
In our example: Difference = 123 - 100 = 23
Now, to find the percentage increase, divide the difference by the original number and multiply by 100:
Percentage Increase = (Difference / Before) · 100%
In our example: Percentage Increase = (23 / 100) · 100% = 23%
A positive percentage increase (+23%) means the number has grown or increased by 23%. That's like getting extra cookies in your jar!
Formula is =(B2-A2)/A2*100, where A2 is the "Before" number, and B2 is the "After" number.
If you want to calculate how much a number has increased in percentage terms, follow these simple steps. For example, let's find the percentage increase from 80 to 100.

The percentage increase from 80 to 100 is 25%.
Scenario: Monthly rent increased from $1,000 to $1,200. What is the percentage increase?
Calculation: Find the percentage increase.
Formula: Percentage Increase = [(New Value - Old Value) / Old Value] × 100%
Percentage Increase = [($1,200 - $1,000) / $1,000] × 100%
Percentage Increase = ($200 / $1,000) × 100% = 0.20 × 100% = 20%
Result: The percentage increase is 20%.
Scenario: Your electricity bill rose from $150 to $180. What is the percentage increase?
