🔍 Guiding Question A business can be profitable on paper yet still run out of cash — so how efficiently must a firm manage its assets, stock, and credit relationships to stay financially healthy, and at what point does poor efficiency tip a business into insolvency?
🌍 Why This Matters In January 2023, UK retailer Wilko was generating revenue but its stock was piling up unsold, suppliers were demanding faster payment, and customers were taking longer to pay. By August 2023 it had entered administration — not because it stopped selling, but because it ran out of cash. Efficiency ratios, had they been monitored closely, would have signalled the crisis months earlier.
What Are Efficiency Ratios?
Profitability ratios tell us whether a business is making money; liquidity ratios tell us whether it can pay its short-term bills. Efficiency ratios sit between these two — they reveal how well a business converts its assets and manages its trading relationships to generate revenue and maintain cash flow.
📘 Efficiency Ratios Efficiency ratios (also called activity ratios) measure how effectively a business manages its key assets — stock, debtors, creditors, and total assets — in relation to its sales revenue or cost of goods sold. They are HL-only tools in IB Business Management.
- Efficiency ratios are calculated from the income statement and the statement of financial position (balance sheet) — so they require both documents.
- They are most useful when compared: against the firm's own previous periods (trend analysis), against industry benchmarks, or against a direct competitor.
- A single ratio in isolation is almost meaningless — context is everything.
- All four ratios connect directly to working capital management : the cycle of cash → stock → sales → debtors → cash.
🔄 The Working Capital Cycle Analogy Think of a business as a water wheel. Cash flows in (customers pay), turns the wheel (operations run), and flows out (suppliers paid, wages met). Efficiency ratios measure how fast and smoothly that wheel turns. If stock sits too long, or debtors take too long to pay, the wheel slows — and eventually stops, even if the river (revenue) is still flowing.
Ratio 1 — Stock Turnover
Every day that stock sits in a warehouse, it ties up cash and risks becoming obsolete or damaged. Stock turnover measures how many times a business sells and replaces its stock in a given period.
