Weeks on hand is an essential metric for understanding how long you can sustain your business operations based on inventory levels. All businesses that sell products need to work out their weeks on hand inventory regularly to prepare for potential stockouts and protect revenue.

Weeks on hand is a metric that measures the number of weeks a company can sustain its operations based on its current inventory levels. It estimates how long the existing inventory can meet the demand before you need to make more.
For instance, if a company has 10,000 units of inventory and the average weekly usage is 1000 units, the weeks on hand is ten weeks (10,000 units / 1000 units per week). Based on the average usage rate, the existing inventory can support operations for around ten weeks before you need to manufacture additional inventory.
Weeks on hand is a useful metric for inventory management. It helps businesses determine how adequate their current inventory levels are, plan for production, manage capital, and make effective decisions about stock replenishment to meet customer demand without facing stock outs or excess inventory.

Need a hand? Here's a step-by-step guide for calculating weeks on hand inventory:
Let’s look at an example.
You want to calculate weeks on hand for a specific product. During a quarter (13 weeks), the total units sold were 500. So, the average weekly usage is 500 units / 13 weeks = 38.46 units per week.
If the current inventory level for that product is 500 units, the calculation would be as follows:
Weeks on hand = 500 units / 38.46 units per week ≈ 13 weeks
