Altman Z-Score Explained

Altman Z-Score Explained

The Altman Z-Score is a financial model designed to estimate the probability of corporate financial distress using accounting-based ratios.

What the Z-Score measures

The model combines profitability, leverage, liquidity, solvency, and efficiency indicators into one score. It was originally developed for manufacturing companies, but variations are often used as a broad distress-risk signal.

General interpretation

  • Higher score: generally indicates lower financial distress risk.
  • Lower score: may indicate elevated financial pressure.
  • Middle zone: requires deeper review because the signal is less clear.

Why it matters

The Z-Score can help identify companies where balance-sheet risk may be rising. It is particularly useful when paired with debt levels, interest coverage, cash flow, and profitability trends.

Limitations

The Altman Z-Score is not a complete credit model and should not be treated as a prediction guarantee. It can be less reliable for financial firms, early-stage growth companies, and businesses with unusual accounting structures.

Important: Use the Altman Z-Score as a screening indicator, not as a standalone investment decision.
