FAQs

What does stock days on hand mean?

Stock days on hand tells you how many days your current inventory is expected to last based on your average daily usage rate. It’s a practical way to estimate coverage, helping you understand whether you need to reorder soon or if you’re carrying more stock than necessary.

Why is average daily usage important in this calculation?

Average daily usage is the number that sets the pace for how quickly inventory gets consumed. If your usage rate is high, your stock will run out faster. If it’s lower, your inventory will last longer. Using a realistic average gives you a more useful estimate for planning replenishment and avoiding stockouts.

What happens if I enter zero or invalid numbers?

The calculator is designed to catch invalid inputs before showing a result. If either field is empty, negative, or non-numeric, it will display: 'Please provide valid positive numbers for both fields.' If Average Daily Usage is zero, it will display: 'Average Daily Usage cannot be zero.' That matters because dividing by zero would make the result invalid.
