The Bottom-Up Market Size Calculator is a tool designed to help businesses estimate the total addressable market (TAM) based on the number of potential customers and the average revenue generated per customer (ARPC). This method offers an easy way to understand market potential by directly assessing customer data.
Formula
The formula used to calculate the Total Addressable Market (TAM) is:
TAM = N * ARPC
Where:
- N is the number of customers.
- ARPC is the average revenue per customer.
How to Use
- Input the number of potential customers (N) into the first field.
- Enter the average revenue per customer (ARPC) in the second field.
- Press the “Calculate” button.
- The total addressable market (TAM) will appear in the result field, indicating the total revenue potential for your market.
Example
Let’s assume you have 1,000 customers and the average revenue per customer is $500. Using the formula:
- Number of Customers (N) = 1,000
- Average Revenue Per Customer (ARPC) = $500
Using the formula: TAM = 1,000 * 500, the result is $500,000.
