Inventory Turnover Ratio Singapore
How many times a company sells and replaces its stock in a year
Inventory Turnover Ratio measures how many times a company sells and replaces its inventory over a given period, calculated as cost of goods sold divided by average inventory. A higher ratio generally signals stronger sales relative to stock held.

- Inventory Turnover Ratio = Cost of Goods Sold ÷ Average Inventory, over a fiscal period.
- A higher turnover ratio generally means faster-moving inventory and less capital tied up in unsold stock.
- Singapore retailers and F&B chains typically run higher turnover than industrial or capital goods companies.
- An unusually high ratio can also signal understocking and lost sales from running out of popular items.
- Investors use inventory turnover trends to flag demand slowdown or inventory write-off risk before it hits the income statement.

What Is Inventory Turnover Ratio?
Inventory Turnover Ratio measures the number of times a company sells through and replenishes its entire inventory over a specific period, usually a fiscal year. It is calculated as Cost of Goods Sold ÷ Average Inventory, where average inventory is typically the mean of the opening and closing inventory balances for the period.
This ratio is a core efficiency metric for any business that holds physical stock — retailers, F&B operators, distributors, and manufacturers. A business that turns over its inventory quickly generates sales and recovers capital faster, reducing the risk of holding obsolete, damaged or unsellable stock.
The inverse relationship also matters: dividing 365 by the inventory turnover ratio gives Days Inventory Outstanding (DIO) — the average number of days inventory sits before being sold — which feeds directly into the Cash Conversion Cycle.
How Does Inventory Turnover Ratio Work in Singapore?
For Singapore-listed companies, inventory turnover varies widely by sector. Supermarket chains and F&B groups typically report high turnover (often 8–15 times a year) because perishable and fast-moving consumer goods must be sold quickly. In contrast, companies selling heavy machinery, specialised electronics components, or luxury goods may turn inventory just 2–4 times a year, which is normal for their business model rather than a sign of weakness.
Singapore’s position as a regional trading and logistics hub means many SGX-listed distributors and trading companies disclose detailed inventory breakdowns in their annual reports, making sector comparison relatively straightforward using SGX-listed company filings and analyst reports.
| Sector | Typical annual turnover |
|---|---|
| Supermarkets / F&B | 8–15x |
| Electronics distribution | 4–8x |
| Heavy machinery / capital goods | 2–4x |
Inventory Turnover Ratio Example
Suppose a Singapore-listed consumer electronics retailer reports Cost of Goods Sold of SGD 120 million for the year, with average inventory of SGD 15 million.
Inventory Turnover Ratio = SGD 120 million ÷ SGD 15 million = 8 times per year.
This means the company sells through its entire average inventory balance eight times a year, or roughly once every 45.6 days (365 ÷ 8). If turnover falls to 5 times the following year with no change in business strategy, it could signal slowing demand, overstocking, or both — worth investigating in the next quarterly results.
Advantages of Inventory Turnover Ratio
- Flags slow-moving or obsolete stock: a falling turnover ratio often precedes inventory write-downs that hit future earnings.
- Signals operational efficiency: higher turnover generally means less capital tied up in unsold goods.
- Easy to benchmark against peers: most SGX-listed retailers and distributors disclose the inputs needed in their annual reports.
- Feeds into cash flow analysis: inventory turnover is a direct input into Days Inventory Outstanding and the Cash Conversion Cycle.
Risks and Limitations
- Comparing turnover ratios across unrelated sectors (e.g. F&B vs. heavy machinery) is not meaningful.
- A very high ratio can indicate chronic understocking and missed sales opportunities, not just efficiency.
- Using year-end inventory instead of an average balance can distort the ratio if inventory is seasonal.
- The ratio doesn’t capture inventory quality — a company could be turning over slow-moving, discounted stock quickly.
Inventory Turnover Ratio vs Days Inventory Outstanding
| Feature | Inventory Turnover Ratio | Days Inventory Outstanding |
|---|---|---|
| Unit | Times per period | Days |
| Formula | COGS ÷ Average Inventory | 365 ÷ Inventory Turnover Ratio |
| Higher = better or worse? | Generally higher is better | Generally lower is better |
The Bottom Line
For Singapore investors, Inventory Turnover Ratio is important because it reveals how efficiently a company manages the stock it holds, directly affecting working capital and cash flow. The ratio is most useful when tracked over time and benchmarked against direct sector peers, rather than viewed as a single standalone number.

Frequently Asked Questions
What is a good inventory turnover ratio?
It depends heavily on the sector — supermarkets and F&B businesses often see 8 to 15 times a year, while heavy machinery or capital goods companies may only turn inventory 2 to 4 times a year. Compare a company against its direct peers, not the broader market.
How do you calculate inventory turnover ratio?
Divide Cost of Goods Sold by average inventory for the period. Average inventory is usually calculated as (opening inventory + closing inventory) ÷ 2.
What does a declining inventory turnover ratio mean?
A declining ratio can signal slowing sales, overstocking, or both. It’s often an early warning sign that should prompt a closer look at a company’s next set of quarterly results.
Can inventory turnover ratio be too high?
Yes. An unusually high ratio can mean a company is chronically understocked, resulting in lost sales when popular items run out — not a sign of pure efficiency.
How does inventory turnover relate to Days Inventory Outstanding?
Days Inventory Outstanding is the inverse, calculated as 365 divided by the inventory turnover ratio. It expresses the same information in days rather than times per year.
