Calculate Your Percentage Increase Now →The Percentage Increase Formula
The basic formula for calculating percentage increase is:
Percentage Increase = [(Current Value - Last Year's Value) / Last Year's Value] * 100
Here's what each component represents:
- Current Value: The value of the metric you're measuring in the present period.
- Last Year's Value: The value of the same metric from the corresponding period last year.
Step-by-Step Calculation
- Find the Difference: Subtract last year's value from the current value. This gives you the amount of increase.
- Divide by Last Year's Value: Divide the increase by last year's value. This gives you a decimal representing the proportional change.
- Multiply by 100: Multiply the decimal by 100 to express the change as a percentage.
Example: Calculating Revenue Growth
Let's say your business had a revenue of $100,000 last year, and this year, your revenue is $120,000. To calculate the percentage increase:
- Find the Difference: $120,000 - $100,000 = $20,000
- Divide by Last Year's Value: $20,000 / $100,000 = 0.2
- Multiply by 100: 0.2 * 100 = 20%
Therefore, your revenue increased by 20% compared to last year.

Percentage Increase vs. Percentage Point Change
It's essential to distinguish between percentage increase and percentage point change. A percentage increase reflects the relative change between two values, whereas a percentage point change represents the absolute difference between two percentages.
For example, if a company's profit margin increased from 5% to 10%, that's a 100% increase in profit margin because (10-5)/5 = 1. The percentage point change is simply 5 percentage points (10% - 5% = 5%).
Why Calculating Percentage Increase Matters
- Trend Identification: Helps in spotting trends and patterns over time.
- Performance Evaluation: Provides a clear metric for evaluating performance against previous periods.
- Goal Setting: Assists in setting realistic and achievable goals for future growth.
- Effective Communication: Simplifies the communication of growth metrics to stakeholders.
Beyond the Basics: Considering Other Factors
While calculating the percentage increase from last year is a valuable tool, it's important to consider other factors that may have influenced the change. These factors can include market conditions, economic trends, and internal business decisions. Analyzing these factors in conjunction with the percentage increase provides a more comprehensive understanding of the situation.
