The Altman Z-Score is a financial metric used to predict the bankruptcy risk of publicly traded manufacturing companies. Developed by Edward I. Altman in 1968, this score combines various financial ratios to assess a company’s credit strength.
The Altman Z-Score is calculated using the following formula:
$$ Z = 1.2X_1 + 1.4X_2 + 3.3X_3 + 0.6X_4 + 1.0X_5 $$
Where:
- \( X_1 \) = Working Capital / Total Assets
- \( X_2 \) = Retained Earnings / Total Assets
- \( X_3 \) = Earnings Before Interest and Taxes (EBIT) / Total Assets
- \( X_4 \) = Market Value of Equity / Total Liabilities
- \( X_5 \) = Sales / Total Assets
Working Capital / Total Assets (\( X_1 \))
This ratio measures a company’s liquidity by comparing its working capital to its total assets.
Retained Earnings / Total Assets (\( X_2 \))
This ratio assesses how much profit a company reinvests in itself compared to its total assets.
EBIT / Total Assets (\( X_3 \))
This ratio evaluates the company’s operational efficiency in generating profits from its assets.
Market Value of Equity / Total Liabilities (\( X_4 \))
This measures the market perception of a company’s net worth relative to its debts.
Sales / Total Assets (\( X_5 \))
This ratio indicates the company’s asset turnover, showing how effectively it uses its assets to generate sales.
Ranges and Their Meanings
- Z > 2.99: The company is in the “Safe” zone, indicating a low risk of bankruptcy.
- 1.81 < Z < 2.99: The company is in the “Gray” zone, indicating a moderate risk of bankruptcy.
- Z < 1.81: The company is in the “Distress” zone, indicating a high risk of bankruptcy.
Applicability
While the Altman Z-Score is primarily designed for publicly traded manufacturing companies, modified versions exist for private firms and non-manufacturers.
Considerations
- Industry Variations: The formula’s accuracy can vary across different industries.
- Economic Conditions: Macroeconomic factors can influence financial ratios, affecting the Z-Score’s accuracy.
Example 1
Company A has the following financial data:
- Working Capital: $500,000
- Total Assets: $2,000,000
- Retained Earnings: $300,000
- EBIT: $700,000
- Market Value of Equity: $1,200,000
- Total Liabilities: $800,000
- Sales: $2,500,000
Using the Altman Z-Score formula:
$$ Z = 1.2 \left( \frac{500,000}{2,000,000} \right) + 1.4 \left( \frac{300,000}{2,000,000} \right) + 3.3 \left( \frac{700,000}{2,000,000} \right) + 0.6 \left( \frac{1,200,000}{800,000} \right) + 1.0 \left( \frac{2,500,000}{2,000,000} \right) = 2.75 $$
Company A falls into the “Gray” zone.

Can the Altman Z-Score be used for non-manufacturing companies?
Yes, but the original formula is tailored for manufacturing companies. Modified versions exist for other types of companies.
How often should the Altman Z-Score be calculated?
It should be calculated regularly, such as quarterly or annually, to monitor a company’s financial health over time.
