How to Calculate Altman Z-score?

The Z-Score is calculated by applying a specific formula that uses key financial data from a company's balance sheet and income statement.

For publicly traded companies, the formula is: Z-Score = 1.2*(Working Capital / Total Assets) + 1.4*(Retained Earnings / Total Assets) + 3.3*(EBIT / Total Assets) + 0.6*(Market Value of Equity / Total Liabilities) + 1.0*(Sales / Total Assets)

where - Working Capital: Current assets minus current liabilities, representing the company’s liquidity. - Total Assets: The sum of all assets owned by the company, both current and long-term. - Retained Earnings: The cumulative net earnings retained in the company after dividends are paid. - EBIT (Earnings Before Interest and Taxes): A measure of the company’s profitability from core operations. - Market Value of Equity: The total market capitalization of the company (share price multiplied by the number of outstanding shares). - Total Liabilities: The total amount of debt and obligations a company owes. - Sales: The total revenue generated from the company’s operations.
