Recommendations
For each SKU we multiply your cost price and retail price by the stock on hand to get cost value and retail value. The difference is your unrealized profit potential. We then look at days since last sale and average monthly sales to flag dead stock and rank SKUs by inventory turnover.
Cost Value = Cost Price × Stock Qty
Retail Value = Retail Price × Stock Qty

Your inventory is one of the largest assets on your Shopify store's balance sheet, but it is also one of the easiest places to silently lose money. Without a clear view of how much capital is tied up in stock, how much potential revenue is sitting on the shelf, and which SKUs are quietly turning into dead weight, it is almost impossible to make confident purchasing or pricing decisions. Our free Shopify Inventory Value Calculator gives you an instant, line-by-line snapshot of total cost value, retail value, profit potential, and inventory turnover so you know exactly where your money is sitting at any given moment.
Tracking inventory value is the foundation of healthy ecommerce financial management. The cost value of your inventory represents the working capital you have locked into physical products, and that capital cannot be used for advertising, hiring, or new product development until those units sell. The retail value tells you the maximum revenue your current stock can generate if everything sells through at full price. Comparing the two reveals your gross profit potential and exposes whether you are sitting on enough inventory to hit your sales targets, or whether you are dangerously overstocked. Investors, lenders, and accountants all use inventory value as a key indicator of business health, and your insurance coverage depends on having an accurate, up-to-date number.
Cost value is what you paid your supplier for the units currently in your warehouse, including landed cost where possible. Retail value is what those same units are worth at your listed selling price before any discounts, promotions, or returns. The gap between the two is your gross margin opportunity, and tracking it at the SKU level is critical because blended margins hide the products that are quietly destroying profitability. A product with a thirty percent margin and high turnover can be more profitable than a product with a sixty percent margin that sits on the shelf for a year. By looking at cost value and retail value side by side, you can spot SKUs that are overpriced relative to demand, underpriced relative to cost, or simply not worth restocking.
Dead stock is inventory that has not sold in ninety days or more, or that sells fewer than one unit per month. It quietly drains profitability in three ways. First, it ties up cash that could be earning a return elsewhere. Second, it occupies warehouse or 3PL space that you are paying for every month. Third, it loses value over time as it becomes obsolete, damaged, or out of season. The longer you wait to clear dead stock, the more money you lose. This calculator flags dead stock automatically so you can take action through liquidation sales, bundle deals, returns to supplier, or in extreme cases write-offs. A healthy Shopify store keeps dead stock under five percent of total inventory value.
Inventory turnover measures how many times you sell through your average inventory in a year, and it is one of the most important efficiency metrics in ecommerce. A high turnover rate means your capital is recycling quickly and your customers are getting fresh stock. A low turnover rate means cash is stagnating in unsold units. Most healthy direct-to-consumer Shopify brands target a turnover rate between four and eight times per year, with fast fashion and consumables often pushing higher and luxury or seasonal goods running lower. By identifying your top performers and worst performers in the table below, you can double down on restocking what works and cut your losses on what does not.
