 Interpret the Result
 Consider Time Period
By following these steps and understanding the underlying concepts, you can accurately calculate growth percentage, enabling you to make informed decisions and track progress effectively.
Identify Starting Value
To calculate growth percentage accurately, it’s essential to first identify the starting value. This represents the initial point from which you measure growth. It serves as the benchmark against which you compare the ending value to determine the extent of change.

Select the Appropriate Starting Point:
Depending on the context and what you’re measuring, the starting value can vary. For instance, in tracking revenue growth, it could be the revenue at the beginning of a specific period, such as a quarter or a year.

Ensure Consistency:
When comparing growth over multiple periods, it’s crucial to use a consistent starting point. This allows for accurate and meaningful comparisons, eliminating the impact of varying starting values.

Consider Relevant Factors:
When selecting the starting value, consider any factors that may have influenced the initial measurement. This could include economic conditions, market trends, or changes in the industry landscape.

Document and Communicate:
Clearly document and communicate the starting value used in your calculations. This ensures transparency and allows others to understand the basis for your growth percentage calculations.
By carefully identifying and selecting the appropriate starting value, you lay the foundation for accurate and reliable growth percentage calculations.
Determine Ending Value
Once you’ve identified the starting value, the next step is to determine the ending value. This represents the final point at which you measure growth. It signifies the current or most recent value against which you compare the starting value to calculate the growth percentage.

Select the Appropriate Ending Point:
Similar to the starting value, the ending value should align with the context and what you’re measuring. For example, if tracking revenue growth, it could be the revenue at the end of the specific period you’re considering.

Ensure Consistency:
When comparing growth over multiple periods, it’s essential to use a consistent ending point. This allows for accurate and meaningful comparisons, eliminating the impact of varying ending values.

Consider Relevant Factors:
When selecting the ending value, consider any factors that may have influenced the final measurement. This could include economic conditions, market trends, or changes in the industry landscape.

Document and Communicate:
Clearly document and communicate the ending value used in your calculations. This ensures transparency and allows others to understand the basis for your growth percentage calculations.
By carefully determining and selecting the appropriate ending value, you ensure that your growth percentage calculations are accurate and reliable.
Calculate the Difference
Once you have identified the starting value and determined the ending value, the next step is to calculate the difference between them. This represents the absolute change that has occurred over the specified period.
To calculate the difference, simply subtract the starting value from the ending value. The result is the absolute change, which can be a positive or negative value.
Here’s the formula for calculating the difference:
Difference = Ending Value – Starting Value
Let’s consider an example to illustrate:
Suppose you’re tracking the growth of your company’s revenue over a quarter. The starting value (revenue at the beginning of the quarter) is $100,000, and the ending value (revenue at the end of the quarter) is $120,000.
To calculate the difference, you would subtract the starting value from the ending value:
Difference = $120,000 – $100,000 = $20,000
The difference in this case is $20,000, indicating an absolute increase of $20,000 in revenue over the quarter.
Calculating the difference is a crucial step in determining the growth percentage, as it provides the basis for understanding the extent of change that has occurred.
By accurately calculating the difference, you lay the foundation for a meaningful and accurate growth percentage calculation.
Divide by Starting Value
Once you have calculated the difference between the ending value and the starting value, the next step is to divide the difference by the starting value.
This step is crucial because it allows you to express the growth as a proportion of the starting value. This is important for understanding the relative magnitude of the growth.
To divide the difference by the starting value, simply use the following formula:
Growth Proportion = Difference / Starting Value
Let’s continue with the example from the previous section, where the difference in revenue over a quarter was $20,000 and the starting revenue was $100,000.
To calculate the growth proportion, you would divide the difference by the starting value:
Growth Proportion = $20,000 / $100,000 = 0.2
The growth proportion in this case is 0.2, which means that the revenue grew by 0.2 times the starting revenue over the quarter.
This step is important because it provides a standardized way of expressing growth, regardless of the absolute values involved. It allows you to compare growth rates across different companies, industries, or time periods.
By dividing the difference by the starting value, you obtain a growth proportion that represents the relative change in relation to the starting point.
Multiply by 100
The next step in calculating the growth percentage is to multiply the growth proportion by 100. This step is important because it converts the growth proportion into a percentage, which is a more commonly understood and relatable unit of measurement.

Express Growth as a Percentage:
By multiplying the growth proportion by 100, you express the growth as a percentage of the starting value. This makes it easier to understand and communicate the magnitude of the growth.

Standardize Comparisons:
Expressing growth as a percentage allows for standardized comparisons across different companies, industries, or time periods. This is because percentages provide a common frame of reference, regardless of the absolute values involved.

Easier Interpretation:
Percentages are more intuitive and easier to interpret than growth proportions. By converting the growth proportion to a percentage, you make it more accessible and understandable to a wider audience.

Consistency with Conventions:
In most business and financial contexts, growth is typically expressed as a percentage. Multiplying the growth proportion by 100 ensures consistency with these conventions.
By multiplying the growth proportion by 100, you obtain the growth percentage, which represents the proportional change in relation to the starting value, expressed as a percentage.
Express as Percentage
The final step in calculating the growth percentage is to express the result as a percentage. This involves adding the percent sign (%) to the growth percentage value.

Complete the Calculation:
By expressing the growth percentage as a percentage, you complete the calculation and obtain the final result. This result represents the proportional change between the starting value and the ending value, expressed as a percentage.

Standardized Unit of Measurement:
Expressing the growth percentage as a percentage provides a standardized unit of measurement. This allows for easy comparison and interpretation of growth rates across different contexts and industries.

Enhanced Communication:
By expressing the growth percentage as a percentage, you enhance communication and understanding. Percentages are widely recognized and understood, making it easier to convey the magnitude of growth to a broader audience.
