What is Percentage Increase?
Percentage increase represents the extent to which a quantity has grown relative to its initial value. It's expressed as a percentage, making it easy to compare changes of different magnitudes. Unlike absolute increases, percentage increase provides a relative measure, highlighting the rate of growth rather than just the raw difference.
The Percentage Increase Formula
The formula to compute percentage increase is straightforward:
Percentage Increase = [(New Value - Original Value) / Original Value] * 100
Where:
- New Value is the value after the increase.
- Original Value is the initial value.
Let's break down how to use this formula with some real-world examples:
Examples of Computing Percentage Increase
Example 1: Calculating Salary Increase
Imagine your starting salary was $50,000, and you received a raise to $55,000. To compute percentage increase, follow these steps:
- Find the difference: $55,000 - $50,000 = $5,000
- Divide by the original value: $5,000 / $50,000 = 0.1
- Multiply by 100: 0.1 * 100 = 10%
Therefore, your salary increased by 10%.
Example 2: Tracking Business Growth
A business had a revenue of $200,000 last year and $250,000 this year. The percentage increase in revenue is:
- Find the difference: $250,000 - $200,000 = $50,000
- Divide by the original value: $50,000 / $200,000 = 0.25
- Multiply by 100: 0.25 * 100 = 25%
The business experienced a 25% increase in revenue.
Example 3: Analyzing Investment Returns
You invested $1,000 in a stock, and its value grew to $1,150. The percentage increase in your investment is:
- Find the difference: $1,150 - $1,000 = $150
- Divide by the original value: $150 / $1,000 = 0.15
- Multiply by 100: 0.15 * 100 = 15%
Your investment increased by 15%.

Percentage Increase vs. Percentage Decrease
It's important to note the difference between percentage increase and percentage decrease. If the new value is lower than the original value, you'll calculate a percentage decrease instead. The formula is similar, but you'll subtract the new value from the original value.
Why is Computing Percentage Increase Important?
- Tracking Progress: Monitor growth in sales, revenue, website traffic, or other key metrics.
- Making Comparisons: Compare changes across different time periods or different sets of data.
- Setting Goals: Establish realistic targets for future growth based on historical percentage increases.
- Understanding Trends: Identify patterns in your data to inform decision-making.
- Financial Analysis: Evaluate investment performance, analyze financial statements, and make informed investment decisions.
Limitations of the Percentage Increase Formula
While useful, the percentage increase formula has limitations. It assumes a linear relationship, which may not always be accurate. It also doesn't account for external factors that may influence the change. Always interpret the results within the proper context.
