Why this tool exists
Managing stock efficiently is critical for any product business. This tool exists to give you a clear picture of how fast you move inventory without having to do complex math by hand. It helps you quickly spot whether you have too much cash tied up in unsold goods or if you are selling out too fast.
When should you use this tool?
- Evaluating retail performance: Check if your clothing store is moving seasonal items fast enough before they go out of style.
- Managing warehouse space: See if slow moving products are taking up valuable space that could be used for your bestsellers.
- Preparing financial reports: Quickly calculate the required metrics for your quarterly investor updates or business loan applications.
- Comparing against competitors: Figure out if your days sales of inventory aligns with standard practices for your specific niche.
How the tool works
You just input your cost of goods sold along with your starting and ending inventory values. The calculator figures out your average inventory for that period. It then divides your cost of goods sold by that average to give you your turnover ratio. Finally, it divides 365 by that ratio to tell you exactly how many days it takes to clear your stock.
Limitations and accuracy
This calculator assumes a standard 365 day year to determine the days sales of inventory. If you are calculating for a specific month or a different accounting period, the days to sell number will need manual adjustment. Also, it relies entirely on the accuracy of your inputted cost of goods sold. Make sure you are using your actual costs and not your retail prices, otherwise your results will be heavily skewed.
Frequently Asked Questions
It depends completely on your industry. Grocery stores might see a ratio of 14 or higher because food spoils quickly. Furniture stores might sit around 2 to 4 because items are expensive and sell much slower.
Inventory is recorded on your balance sheet at its actual cost. If you use total sales, which includes your profit margin, the calculation becomes inaccurate and makes it look like you sell faster than you actually do.
A high number means it takes a long time to sell your products. You might be overstocking or demand for your product has dropped. This ties up your cash and increases storage costs.
Yes, you can use monthly data to find the ratio. However, the days to sell output assumes a full year of 365 days. For a single month, you will need to divide the number of days in that specific month by your calculated ratio.
