Understanding the Altman Z score

What is the Altman Z score?

The Altman Z Score is a financial model that plays a pivotal role in assessing a company’s financial stability. Developed by Edward I. Altman in 1968, this score is used to predict a company’s likelihood of going bankrupt or experiencing financial distress within two years. It is particularly valuable for investors and creditors who want to make informed decisions regarding their investments or lending.

The components of the Altman Z score

The Altman Z Score considers several financial ratios and metrics to evaluate a company’s financial health:

  • Working Capital to Total Assets Ratio: This measures a company’s ability to meet its short-term obligations.
  • Retained Earnings to Total Assets Ratio: This reflects the proportion of a company’s total assets that are financed by retained earnings.
  • Earnings Before Interest and Taxes (EBIT) to Total Assets Ratio: EBIT is a measure of operational profitability relative to total assets.
  • Market Value of Equity to Book Value of Total Liabilities Ratio: This ratio assesses how the market values a company compared to its total debt.
  • Sales to Total Assets Ratio: It gauges how efficiently a company generates sales relative to its total assets.

Calculating the Altman Z score

The Altman Z Score is calculated using the following formula:

Altman Z Score = 1.2A + 1.4B + 3.3C + 0.6D + 1.0E


  • A = Working Capital to Total Assets Ratio

  • C = Earnings Before Interest and Taxes (EBIT) to Total Assets Ratio
  • D = Market Value of Equity to Book Value of Total Liabilities Ratio
  • E = Sales to Total Assets Ratio
