The Average Daily Demand (ADD) is a key metric in inventory management, supply chain optimization, and business planning. It helps businesses understand the typical demand for a product or service on a daily basis. By calculating the average daily demand, businesses can plan more effectively, ensuring that inventory is replenished at the right times and resources are allocated properly. This metric is vital for forecasting, especially for businesses that operate in industries with fluctuating demand, such as retail and manufacturing.
Formula
The formula to calculate the Average Daily Demand (ADD) is:
ADD = TD / D
Where:
- ADD represents the Average Daily Demand.
- TD is the Total Demand (total number of units demanded over a specific period).
- D is the number of days in the period.
How to Use
- Enter the Total Demand (TD): This is the total number of units or products demanded over a given period.
- Enter the Number of Days (D): This represents the number of days during which the demand is measured.
- Click the “Calculate” button: After entering both the total demand and the number of days, click the “Calculate” button to get the average daily demand.
- View the Result: The Average Daily Demand (ADD) will be displayed, providing an estimate of how much is needed on average each day.
Example
Let’s say a company experiences a total demand of 10,000 units over a period of 30 days. Using the formula ADD = TD / D, we can calculate the average daily demand:
ADD = 10,000 / 30 = 333.33
Therefore, the average daily demand is 333.33 units.

- ADD provides a starting point for forecasting by giving an estimate of how much demand to expect each day.
- Can I use ADD for seasonal demand?
- ADD works for both seasonal and non-seasonal demand, though seasonal trends may require adjustments in forecasting models.
- How does ADD relate to capacity planning?
- ADD helps determine if the current production capacity is sufficient to meet daily demand, helping businesses plan for expansions or adjustments.
- Is ADD useful for short-term or long-term planning?
- ADD is useful for both short-term and long-term planning, though additional analysis may be needed for longer-term trends.
- What should I do if my ADD is too high?
- If your ADD is too high, consider reviewing your demand forecast, adjusting your supply chain, or optimizing your production processes.
- Can ADD be calculated for a specific product?
- Yes, ADD can be calculated for individual products to understand their daily demand.
- What if the number of days is not fixed?
- If the number of days varies, adjust the formula by using the exact number of days for each specific period.
- How does ADD help with budgeting?
- ADD helps in budgeting by providing an estimate of the resources needed to meet daily demand, allowing for better financial planning.
- Can ADD be automated in inventory systems?
- Yes, modern inventory systems can automate the calculation of ADD, helping businesses streamline inventory management.
