trade payables turnover (days): calculation and interpretation

What is Trade Payables Turnover (Days)?

It measures how many days, on average, a company takes to pay its suppliers after receiving goods or services. Think of it as the “payment lag” – the longer the lag, the more cash the company keeps on hand, but it may risk supplier trust.

Formula

Use the following equation:

$$\text{Days Payable Outstanding (DPO)} = \frac{\text{Average Trade Payables}}{\text{Cost of Sales per Day}}$$

Since Cost of Sales per Day = Total Cost of Sales ÷ 365, the formula can also be written as:

$$\text{DPO} = \frac{\text{Trade Payables}}{\text{Cost of Sales}} \times 365$$

🔍 Key Inputs:

• Trade Payables – the amount owed to suppliers at year‑end.
• Cost of Sales – the total cost of goods sold during the year.

Step‑by‑Step Calculation Example

1. Collect the figures:
   • Trade Payables: £50,000
   • Cost of Sales: £300,000
2. Plug into the formula:

   DPO = (50,000 ÷ 300,000) × 365

3. Compute:

   DPO = 0.1667 × 365 ≈ 60.8 days

4. Interpret:

   On average, the company takes about 61 days to pay its suppliers.

Interpretation & What It Means

📈 Higher DPO → The firm keeps cash longer, improving liquidity.

⚠️ Too high → Suppliers may be unhappy; could lead to stricter credit terms.

📉 Lower DPO → The firm pays suppliers quickly, which may strengthen relationships but uses cash faster.

💡 Trend Analysis – Compare DPO over several years. A rising trend might signal cash‑flow pressure.

🏭 Industry Benchmark – Compare with peers; a DPO far above the average could indicate aggressive cash‑management tactics.

Examination Tips

• 📌 Show the formula clearly and label each variable.
• 📌 Explain the interpretation in plain language, linking to cash flow and supplier relations.
• 📌 Use a realistic example (like the one above) to demonstrate calculation.
• 📌 Compare with industry averages if data is provided; discuss implications.
• 📌 Check for rounding – round to the nearest whole day unless the question specifies otherwise.
