Important Financial Ratios for Managers

Big idea​

Ratios are how managers turn raw financial statements into a managerial verdict. A single year's net profit number means almost nothing; the same number expressed as net margin, ROE, ROCE, interest coverage, debtor days and current ratio — then compared to industry peers and prior years — tells you whether the firm is healthy, levered, efficient, and well-run. Prof. Saumya Ranjan Dash groups the working ratios into five families: profitability, liquidity, solvency, efficiency, and valuation. The DuPont decomposition then ties three of them together: ROE = Net Margin × Asset Turnover × Equity Multiplier. Together these are the diagnostic toolkit you bring to every board pack, investment memo, and competitor scan.

Key concepts​

  • Profitability ratios. Gross margin, EBITDA margin, operating margin, net margin, ROE, ROA, ROCE. Each reveals what the others hide — net margin shows after-everything return, ROCE shows return on the capital actually employed in operations.
  • Liquidity ratios. Current ratio (>2.0 rule of thumb), quick/acid-test ratio (excludes inventory), cash ratio. A profitable firm can still fail — these ratios tell you whether it can pay next month's bills.
  • Solvency / leverage ratios. Debt-to-equity, debt-to-capital, interest coverage (EBIT / Interest). Below 1.5× interest coverage is a red flag; below 1× means operations can't cover the interest bill.
  • Efficiency / activity ratios. Inventory turnover, asset turnover, debtor days (DSO), creditor days (DPO), cash conversion cycle (DSO + DIO – DPO). Shorter CCC means less working capital trapped in the operating cycle.
  • Valuation ratios. P/E, P/B, EV/EBITDA, dividend yield. They tell you what the market is pricing in — always compare with fundamentals, never read in isolation.
  • The DuPont decomposition. ROE = Net Margin × Asset Turnover × Equity Multiplier. Lets you diagnose why ROE moved — margin improvement, asset efficiency, or simply more leverage — not just that it moved.

Self-check​

Firm A and Firm B both report ROE of 18%. Firm A: net margin 12%, asset turnover 1.0, equity multiplier 1.5. Firm B: net margin 4%, asset turnover 1.5, equity multiplier 3.0. What does the DuPont decomposition tell you?

  • A. Both firms are equally healthy
  • B. Firm B is healthier because it has higher asset turnover
  • C. Firm A earns its ROE from operating efficiency; Firm B leverages debt heavily and is riskier
  • D. ROE cannot be decomposed this way
Write the DuPont decomposition of ROE
ROE = Net Margin × Asset Turnover × Equity Multiplier = (Net Income / Sales) × (Sales / Assets) × (Assets / Equity). Lets you split a single ROE number into profitability, efficiency and leverage drivers.

🪞 Apply it — reflection prompts
  1. Run a DuPont decomposition on your firm vs your two closest peers. Where is your ROE coming from — margins, efficiency, or leverage — and is that sustainable?
  2. Pull your firm's cash conversion cycle for the last five years. If it's lengthening, which of DSO, DIO or DPO is the culprit, and what would shorten it?
  3. What is your firm's interest coverage ratio? At what level would a downgrade scenario be triggered, and what's the buffer today?
