Altman Z-Score: formula and how to read it

Edward Altman introduced the Z-Score in 1968 to estimate the risk of a company running into financial distress. It combines five balance-sheet and income ratios into one number.

What is Altman Z-Score?

Bankruptcy risk; above 3 is safe, below 1.8 is distressed. 1.2×working capital + 1.4×retained earnings + 3.3×operating income + 1.0×sales, each divided by total assets, plus 0.6×market value ÷ total liabilities. Not calculated for financial, utility or real-estate companies, whose heavy debt is normal for their business.

Stock Meadow groups it under Financial health, and shows it in tables as Altman Z.

Formula and a worked example

Z = 1.2×(working capital ÷ total assets) + 1.4×(retained earnings ÷ total assets) + 3.3×(operating income ÷ total assets) + 1.0×(sales ÷ total assets) + 0.6×(market value of equity ÷ total liabilities)

A company whose five terms add up to 3.4 sits in the safe zone. One scoring 1.5 sits in the distress zone. The numbers are made up for illustration.

How to read it

A higher score means lower estimated bankruptcy risk. Above about 3 is generally read as safe, between about 1.8 and 3 as a grey zone, and below 1.8 as distressed.

When Stock Meadow ranks stocks, a higher figure scores better. On a stock, a score below 1.81 (the distress zone) raises a warning flag, and above 2.99 is the safe zone.

Common pitfalls

  • The model was built on manufacturing companies in the 1960s, so it fits other business types less well.
  • Not calculated for financial, utility or real-estate companies, whose heavy debt is normal for their business.
  • A score is a risk signal, not a prediction that any company will fail.

How Stock Meadow handles gaps. Usually blank when the balance-sheet figures it needs aren't available.

Treat any single metric as one clue, and read the company's financial statements before drawing a conclusion. Stock Meadow's figures are research tools based on reported data, not investment advice.
