The formula to calculate the list growth rate is:
\[ \text{GR} = \left( \frac{\text{FS} - \text{IS}}{\text{IS}} \right) \times \left( \frac{365}{\text{TP}} \right) \times 100 \]
Where:
List growth rate is a metric used to measure the rate at which a list (such as an email subscriber list, customer base, or social media following) is growing over a specific time period. It is an important indicator of the health and expansion of a business’s outreach or marketing efforts.
Let's assume the following values:
Step 1: Subtract the initial list size from the final list size:
\[ \text{FS} - \text{IS} = 1500 - 1000 = 500 \]
Step 2: Divide by the initial list size:
\[ \frac{500}{1000} = 0.5 \]
Step 3: Multiply by the ratio of 365 days to the time period:
\[ 0.5 \times \frac{365}{30} \approx 6.083 \]
Step 4: Multiply by 100 to convert to a percentage:
\[ 6.083 \times 100 \approx 608.33 \]
Therefore, the list growth rate is approximately 608.33%.
