Have you ever wondered how financial experts assess the credit risk of a company?
One tool used for this purpose is the Z-score.
In simple terms, the Z-score is a quantitative metric that helps analysts and investors measure the likelihood of a company experiencing financial distress or, in more extreme cases, bankruptcy.
Calculating the Z-Score
Developed by Edward Altman in the 1960s, the Z-score consists of multiple financial ratios, each multiplied by a specific weight for better accuracy.
This value helps determine whether a company is in the safe zone, at risk of distress, or even facing bankruptcy.
The Z-score formula includes the following:
- Working Capital / Total Assets
- Retained Earnings / Total Assets
- Earnings Before Interest and Taxes / Total Assets
- Market Value of Equity / Total Liabilities
- Sales / Total Assets
By calculating these ratios and then combining them with their respective weighting factors, a resulting Z-score will appear.

A higher score represents a healthier financial status for the company, while a lower score indicates an increasing chance of financial distress.
Interpreting Z-Score Results
With the combined results, the Z-score usually falls into three main ranges:
- Above 3.0: Generally considered a safe zone. This means the company remains financially stable and has a low probability of bankruptcy.
- Between 1.8 and 3.0: Falling within a gray zone, the company might face possible financial struggles without necessarily sinking into bankruptcy.
- Below 1.8: This range represents the distress zone, where a company is highly likely to face bankruptcy or severe financial problems.
Do keep in mind that Z-scores do have limitations.
The numbers can change for a company over time, and not all industries or sizes of companies fit neatly within this scope.
Contributing to Informed Investment Decisions
The Z-score is only one tool among many used for assessing a company’s financial health.
Information such as a firm’s balance sheet, cash flow statement, and income statement, as well as financial market trends, help make informed investment decisions.
Although a company’s Z-score doesn’t entirely dictate its fate, it’s a helpful barometer for analyzing overall credit risk and impending financial troubles.

1. Who developed the Z-score for bankruptcy prediction?
The Z-score was developed by Dr. Edward Altman in the 1960s.
