To calculate inventory days for your business, divide your cost of goods sold (COGS) by 365 days. With good inventory forecasting, you’ll be more likely to have the items when needed and minimise the risk of being left with obsolete or unsellable stock. To achieve this, you’ll need to know your inventory days and other metrics, such as economic ordering quantity, carrying costs and others. When DSI increases, it means that it will take more days to sell your stock of inventory items. This is a sign that either the rate of sales has decreased or the size of your inventory has increased. Many experts concur that a decent days’ supply indicator (DSI) should be between thirty and sixty days in order to effectively manage inventories and balance idle stock with being understocked.

By finding out the inventory days, you would be able to calculate both of the above ratios. The growth rate of our company’s cost of goods sold (COGS) is assumed to reach 4.0% by the end of 2027, with the change in the growth rate occurring in equal increments. The next part of our exercise comprises forecasting our company’s ending inventory across the five-year projection period. In the best-case scenario, no further action might be necessary, as the accumulation of inventory could be a byproduct of targeting a niche customer segment and operating in a cyclical market that balances out over the long run.

While the DSO ratio measures how long it takes a company to receive payment on accounts receivable, the DPO value measures how long it takes a company to pay off its accounts payable.

Why is calculating inventory days important?
Investors and creditors want to know more about the business sales performance. The more liquid a company is, it will likely translate into having higher cash flows and bigger returns. For example, costs can include the likes of labor costs and utilities, such as electricity. Ultimately, they’re defined as the costs incurred to acquire or manufacture any products that are created to sell throughout a inventory days formula specific period. Managing your DSI can be challenging since it can be subject to external factors like seasonality and economic trends.

Reducing the size of your inventory can help alleviate unnecessary storage costs and reduce staffing needs—all while decreasing your DSI. Conversely, if your DSI is too low, you may want to increase your inventory so you don’t run out. A financial ratio called inventory turnover indicates how frequently a business rotates its stock in relation to its cost of goods sold (COGS) during a specific time frame. If we consider that there are 365 days a year, we can see the days it takes for the firm to transform inventories into finished stocks. All we need to do is divide the number of days in a year by the inventory turnover ratio. To efficiently manage the inventory and balance idle stock, days in sales inventory over between 30 and 60 days can be a good ratio to strive for.
Importance of Days Sales Inventory to Investors
Knowing how to calculate DIS and interpret the information can help provide insights into the sales and growth of a company. This is often important information that investors and creditors find valuable, and the company size doesn’t usually matter. The figure that you end up with helps indicate the liquidity of inventory management and highlights how many days the current inventory a company has will last. Typically, having a lower DSI is going to be preferred since it means it will take a shorter amount of time to clear inventory. Yet, the average DSI is going to differ depending on the company and the industry it operates. Days Sales of Inventory (DSI) analysis involves assessing how efficiently a company manages its inventory by measuring the average number of days it takes to sell its inventory stock.
Days Sales of Inventory Formula and Calculation

Keeping your inventory days as low as possible reduces this risk, especially if your industry is significantly impacted by shifting fashions and consumer preferences.
