Percentage Increase: How to Calculate It Easily
Calculating percentage increase is a fundamental skill with wide applications, from understanding financial reports to tracking personal progress. This guide will walk you through the process, providing clear steps and examples to help you master this essential calculation.
Understanding Percentage Increase
Before diving into the formula, let's clarify what percentage increase represents. It measures the relative change between an initial value and a final, larger value. In simpler terms, it shows how much a value has grown proportionally.
The Formula for Percentage Increase
The formula for calculating percentage increase is straightforward:
[(New Value - Old Value) / Old Value] x 100%
Let's break down each component:
- New Value: This is the final value after the increase.
- Old Value: This is the initial value before the increase.
Step-by-Step Calculation Guide
Here's a step-by-step guide to calculating percentage increase, illustrated with examples:
Example 1: Simple Increase
Let's say you had 10 apples, and now you have 15. What's the percentage increase?
Step 1: Find the difference:
15 (New Value) - 10 (Old Value) = 5
Step 2: Divide the difference by the old value:
5 / 10 = 0.5
Step 3: Multiply by 100%:
0.5 x 100% = 50%
Therefore, there's a 50% increase in the number of apples.
Example 2: More Complex Scenario
Imagine your business's revenue increased from $50,000 to $75,000. What's the percentage increase?
Step 1: Find the difference:
$75,000 (New Value) - $50,000 (Old Value) = $25,000
Step 2: Divide the difference by the old value:
$25,000 / $50,000 = 0.5
Step 3: Multiply by 100%:
0.5 x 100% = 50%
The business experienced a 50% revenue increase.
Common Mistakes to Avoid
- Using the wrong values: Always ensure you're using the correct new and old values. Double-check your figures.
- Incorrect order of subtraction: Remember to subtract the old value from the new value.
- Forgetting the multiplication by 100%: This crucial step converts the decimal into a percentage.

Understanding percentage increase is invaluable in various situations:
- Finance: Tracking investment returns, analyzing sales growth, and understanding inflation rates.
