What is Percentage Increase?
Percentage increase is a mathematical concept that measures the growth of a value over time, expressed as a percentage of the original value. This calculation is widely used in fields such as finance, economics, and data analysis to track changes and make comparisons.
By calculating the percentage increase, you can assess how much a value has grown compared to its starting point. This is particularly useful for analyzing trends in pricing, revenue, population growth, and other key metrics.
Key points
- A positive percentage increase indicates growth.
- A negative percentage increase indicates a decrease, which can also be referred to as a percentage decrease.
- Percentage increase is a relative measure, allowing for comparisons between values of different scales.
It is important to use the correct original value as the reference point for the calculation.
How to Calculate Percentage Increase
Percentage increase can be easily determined by calculating the difference between the final value and the initial value and then expressing that difference as a percentage of the initial value. This can be done using a simple three-step process:
- Subtract the initial value from the final value to obtain the difference.
- Divide the difference by the absolute value of the initial value.
- Multiply the result by 100 to express it as a percentage.
Percentage Increase Formula
This three-step process can be summarized using the following mathematical formula:
\[
\text{Percentage Increase} = \left( \frac{\text{Final Value} – \text{Initial Value}}{\text{Initial Value}} \right) \times 100
\]
Where “Initial value” represents the value or amount before the increase and “Final value” is the value after the Increase.
By comparing the initial and final values, you can determine the extent of the change and calculate the percentage increase, which shows the growth relative to the initial amount.
Example Calculations of Percentage Increase
Example 1: Let’s say the price of a product increases from $36 to $45. We can calculate the percentage increase using the above three-step method:
Find the Difference:
\[ 45 – 36 = 9 \]
Divide by the Initial Value:
\[ \frac{9}{36} = 0.25 \]
Convert to Percentage:
\[ 0.25 \times 100 = 25\% \]
Therefore, the price has increased by 25% from the previous year to the current year.
Example 2: Now, Let’s consider another example involving larger numbers. Suppose a company’s annual revenue increased from $1,200,000 to $1,500,000 over the course of a year.
We can calculate the percentage increase using the same step-by-step Calculation as follows:
Calculate the Difference:
- Final Value: $1,500,000
- Initial Value: $1,200,000
The difference will therefore be:
\[
1,500,000 – 1,200,000 = 300,000
\]
Divide by the Initial Value:
\[
\frac{300,000}{1,200,000} = 0.25
\]
Convert to Percentage:
\[
0.25 \times 100 = 25\%
\]
Thus, the company’s revenue increased by 25% from the previous year to the current year.
