What Is a Dead Stock Calculator?
A dead stock calculator helps you identify which products in your inventory have stopped moving and calculates the cost of holding them. Stock that hasn't sold or been used in over 90 days is classified as dead stock — it ties up cash, consumes warehouse space, and incurs ongoing holding costs every month. By identifying dead stock early and quantifying its cost, you can take action to liquidate, discount, or return it before it becomes a write-off.
How to Identify Dead Stock in 3 Steps
Step 1 — Set Your Annual Holding Rate
The annual holding rate is the percentage of stock value it costs you to hold inventory for a year — typically 20–30%. This covers warehouse rent, insurance, capital cost, and spoilage risk.
Step 2 — Add Your Products
For each product, enter the name, quantity on hand, unit cost, and the date of last movement (last sale, transfer, or use). You can add as many products as needed.
Step 3 — Review Status and Costs
Each product is automatically classified as Active (<30 days), Slow Moving (30–90 days), or Dead Stock (>90 days). The summary shows total dead stock value and monthly holding cost.

Frequently Asked Questions
What is dead stock?
Dead stock (or dead inventory) is inventory that has not had any movement — no sales, transfers, or use — for an extended period. In most businesses, stock with no movement for more than 90 days is considered dead stock.
What is the difference between dead stock and slow-moving inventory?
Slow-moving inventory has had some movement within the past 30–90 days but turns over much more slowly than your fast-moving items. Dead stock has had no movement at all for 90+ days. Both tie up cash and incur holding costs.
How is monthly holding cost calculated?
Monthly Holding Cost = (Unit Cost × Quantity × Annual Holding Rate%) ÷ 12. For example, ₹1,00,000 worth of stock at a 25% annual holding rate costs ₹2,083 per month just to hold.
What should I do with dead stock?
Common strategies: discount and liquidate, bundle with fast-moving items, return to supplier (if negotiated), donate for a tax write-off, or scrap. The longer you hold dead stock, the more it costs — act quickly once identified.
What annual holding rate should I use?
A commonly used rate is 20–30% of inventory value per year. This covers storage/rent, insurance, capital tied up (opportunity cost), and the risk of spoilage or obsolescence. Use 25% as a default if you are unsure.
