 # Annual Demand Formula

## What is Annual Demand?

The annual demand represents the amount of inventory a company requires to fulfill its sales demands and revenue goals each year or for a particular accounting period. A company can determine the annual demand by checking its income statement for the previous year and identifying the average number of products it sells annually.

## Significance of Annual Demand Formula in E-commerce Business

average ordering cycle

Here,

Average number of products sold annually: It denotes the average lot size of products a company sells annually.

Average ordering cycle: It denotes the average duration of ordering the products.

## How to Use the Annual Demand Formula to Calculate a Business’ Annual Demand?

Suppose company XYZ sells 100 units of schoolbags annually. Its ordering cycle averages to 2 months. As per the formula, annual demand is calculated as follows,

Annual Demand = (12 * 100) /2 = 600

So, company XYZ needs to maintain 600 school bags in its inventory to meet the sales demand for each year.
