Altman Z-Score (Insolvency Risk)
Estimate insolvency risk with the Altman Z-Score, combining working capital, retained earnings, EBIT, book equity and total assets/liabilities into a single distress indicator.
Dati verificati · luglio 2026
Does a Z-Score in the distress zone mean the company will fail?
No — it flags a statistically elevated risk of insolvency within two years based on historical patterns, not a certainty. It should trigger closer review, not an automatic conclusion.

Tutto su Altman Z-Score (Insolvency Risk)
📋Presentazione+
The Altman Z-Score combines five weighted financial ratios — working capital to total assets, retained earnings to total assets, EBIT to total assets, book value of equity to total liabilities, and (in some variants) sales to total assets — into a single score. Scores above roughly 2.99 indicate a 'safe' zone, between 1.81 and 2.99 a 'grey' zone of elevated risk, and below 1.81 a 'distress' zone historically associated with a high probability of insolvency within two years.
💡 Buone pratiche
- The Z-Score was developed on US manufacturing data — treat the exact thresholds as directional for UK service businesses, not a precise cutoff.
- A single low reading can be distorted by an unusual one-off item (asset write-down, exceptional cost) — check the trend across several periods.
- Combine the Z-Score with qualitative signals (customer concentration, covenant headroom, cash runway) rather than relying on it alone.
🔢 Esempio concreto
£100,000 working capital, £150,000 retained earnings, £80,000 EBIT on £600,000 total assets, £300,000 total liabilities and £250,000 book equity: a Z-Score comfortably in the safe zone.

📚Glossario+
- Z-Score
- A weighted combination of balance sheet and income statement ratios developed by Edward Altman to predict the probability of corporate insolvency within two years.

- The Z-Score band (roughly 1.81 to 2.99) where insolvency risk is elevated but not conclusively predicted — warranting closer monitoring rather than immediate alarm.
