What Is Inventory Turnover Ratio?
Inventory turnover ratio measures how many times you sell and replace your entire inventory in a year. A higher ratio means inventory moves quickly, your capital is working hard. A low ratio means capital is sitting idle in stock, generating holding costs and obsolescence risk.
For Pakistan SMEs, particularly in manufacturing and distribution, low inventory turnover is one of the most common causes of cash flow pressure. Working capital tied up in slow-moving stock cannot be used for growth, debt service, or opportunities.
Pakistan Industry Benchmarks
| Sector | Benchmark Range | DSI (Days) | What It Means |
|---|
| FMCG / Retail | 8–12× per year | 30–45 days | Fast-moving consumer goods; any lower signals overstocking |
| Manufacturing | 4–6× per year | 60–90 days | Longer production cycles justified; below 4× is a problem |
| Pharma / Healthcare | 3–5× per year | 73–121 days | Regulatory minimums and shelf-life drive higher stock |
| Energy / Utilities | 2–4× per year | 91–182 days | Spare parts and MRO have inherently lower turnover |
| Construction | 2–3× per year | 121–182 days | Project-based demand creates lumpy inventory cycles |
Worked Example
A business with Rs 60 million in annual COGS and Rs 15 million in average inventory has an inventory turnover ratio of 4.0, meaning stock turns over four times a year, roughly equivalent to 91 days of inventory on hand.
Common Mistakes to Avoid
- Comparing turnover ratio across companies with different business models without adjusting for that difference
- Using ending inventory instead of an average across the period, which distorts the ratio depending on when the snapshot is taken
- Chasing a higher turnover ratio without limit, which can create stockouts if pushed too aggressively
- Reporting one blended ratio instead of breaking it down by product category, hiding both very fast and very slow movers
Frequently Asked Questions
What does Days Sales of Inventory (DSI) mean? ▼
DSI is the flip side of turnover ratio, it tells you how many days of average demand you currently have in stock. DSI = 365 ÷ Turnover Ratio. If your turnover is 4× and DSI is 91 days, you have about 3 months of stock on hand. Whether that is right depends on your sector, lead times, and service level requirements.
How can I improve my inventory turnover? ▼
The most effective approaches are: (1) identify and eliminate dead and slow-moving stock; (2) reduce reorder quantities using EOQ, smaller, more frequent orders keep inventory lean; (3) improve demand forecasting to avoid over-purchasing; (4) implement ABC classification and focus your management effort on A-class items; (5) negotiate shorter lead times with suppliers to reduce required safety stock. Safe Chain Solver delivers these improvements in 30–90 day engagements.
Is a higher inventory turnover always better? ▼
Not always. Extremely high turnover (above industry benchmark) can indicate insufficient safety stock, meaning you risk stockouts, production stoppages, or lost sales. The goal is the right turnover for your service level requirements, not the highest turnover possible. Use the Safety Stock Calculator alongside this tool to ensure your lean inventory levels are supported by appropriate buffers.
What is a good inventory turnover ratio? ▼
It is highly industry-dependent. FMCG distributors often run 8 to 12 turns a year, while industrial equipment distributors may run 2 to 4. Benchmark against your specific sector rather than a generic target.
How does turnover relate to Days of Inventory? ▼
They are inverses of the same underlying relationship, 365 divided by the turnover ratio gives Days of Inventory. Use whichever framing is more intuitive for your own reporting.
