ADD = TD / D

Variables:

  • ADD is the average daily demand
  • TD is the total demand
  • D is the number of days

To calculate the average daily demand, divide the total demand by the number of days.

What is Average Daily Demand?

Average daily demand refers to the average amount of a product or service that is consumed or required each day over a specified period. This metric is crucial for inventory management, supply chain planning, and understanding consumer behavior. By knowing the average daily demand, businesses can ensure they have enough stock to meet customer needs without overstocking, which can lead to increased holding costs.

How to Calculate Average Daily Demand?

The following steps outline how to calculate the Average Daily Demand.


  1. First, determine the total demand over the specified period (TD).
  2. Next, determine the number of days in the period (D).
  3. Finally, calculate the average daily demand using the formula ADD = TD / D.
  4. After inserting the values and calculating the result, check your answer with the calculator above.
