Calculating percentage increase is a fundamental skill with wide-ranging applications, from analyzing financial reports to understanding growth trends. Whether you're tracking your investment returns or evaluating the success of a marketing campaign, mastering this calculation is key. This guide breaks down the process step-by-step, making it easy for everyone to understand.
Understanding Percentage Increase
Before diving into the calculations, let's clarify what percentage increase represents. It measures the relative change between an initial value and a final value, expressed as a percentage. Essentially, it answers the question: "How much did something grow proportionally?"
Key Terms:
- Original Value: The starting amount or value.
- New Value: The final amount or value after the increase.
- Increase: The difference between the new value and the original value (New Value - Original Value).
The Formula for Percentage Increase
The formula for calculating percentage increase is straightforward:
[(New Value - Original Value) / Original Value] x 100%
Let's break this down:
- Find the difference: Subtract the original value from the new value.
- Divide by the original value: This gives you the increase as a decimal.
- Multiply by 100%: Convert the decimal to a percentage.
Step-by-Step Examples
Let's work through a couple of examples to solidify your understanding:
Example 1: Simple Increase
Suppose your monthly salary increased from $2,000 to $2,500. What's the percentage increase?
- Difference: $2,500 - $2,000 = $500
- Divide by original: $500 / $2,000 = 0.25
- Multiply by 100%: 0.25 x 100% = 25%
Therefore, your salary increased by 25%.
Example 2: More Complex Scenario
Imagine a company's annual revenue grew from $100,000 to $150,000. What's the percentage increase?
- Difference: $150,000 - $100,000 = $50,000
- Divide by original: $50,000 / $100,000 = 0.5
- Multiply by 100%: 0.5 x 100% = 50%
The company's revenue increased by 50%.
