The Altman z-score is a bankruptcy prediction calculation.
The z-score measures the probability of insolvency (inability to pay debts as they become due).
1.8 or less indicates a very high probability of insolvency.
1.8 to 2.7 indicates a high probability of insolvency.
2.7 to 3.0 indicates possible insolvency.
3.0 or higher indicates that insolvency is not likely.
The Altman z - score is included in the financial statement ratio analysis spreadsheets highlighted in the left column, which provide formulas, definitions, calculation, charts and explanations of each ratio.
