The Altman Z-Score predicts bankruptcy with 80-90% accuracy up to 2 years in advance. Z = 1.2(WC/TA) + 1.4(RE/TA) + 3.3(EBIT/TA) + 0.6(MV Equity/TL) + 1.0(Sales/TA). Zones: >2.99 = Safe, 1.81-2.99 = Grey Zone, <1.81 = Distress. Enron's Z-Score dropped from 3.2 to 1.1 before collapse — investors who tracked it could have exited early. Lehman Brothers showed distress signals 18 months before bankruptcy. Developed by Edward Altman at NYU in 1968, it remains one of the most widely used credit risk models in finance.

📋 Key Takeaways
- • Z = 1.2×WC/TA + 1.4×RE/TA + 3.3×EBIT/TA + 0.6×MVE/TL + 1.0×Sales/TA
- • > 2.99 = Safe Zone; 1.81–2.99 = Grey Zone; < 1.81 = Distress Zone
- • Z'-Score (private companies) and Z''-Score (non-manufacturing) are variants
- • 80-90% accuracy in predicting bankruptcy within 2 years
💡 Did You Know?
📖 How It Works
- The Five Ratios Explained: X1 = WC/TA (liquidity), X2 = RE/TA (profitability & age), X3 = EBIT/TA (operating efficiency), X4 = MVE/TL (solvency), X5 = Sales/TA (asset turnover).
- Score Zones: Z > 2.99 = Safe; 1.81–2.99 = Grey; < 1.81 = Distress.
- Model Variants (Z', Z''): Z' uses book value for private firms; Z'' omits X5 for non-manufacturing.
- Famous Predictions and Misses: Lehman, Enron, WeWork, GM — all showed distress signals; the model has 80-90% accuracy.
🎯 Tips
- X3 (EBIT/Assets) has the highest weight — focus on operating efficiency first when Z-Score is low.
- Use financial statements from the same accounting period for accuracy.
- For private companies, use book value of equity instead of market value in X4.
- Calculate quarterly or annually to track trends; compare with industry peers.
- The model works best for established companies, not startups.

❓ Frequently Asked Questions
What is the Altman Z-Score?
The Altman Z-Score is a financial formula developed by Professor Edward Altman at NYU in 1968 to predict corporate bankruptcy. It combines five financial ratios into a single score that indicates the likelihood of financial distress within 2 years. It remains one of the most widely used credit risk models in finance.
What is the Z-Score formula?
Z = 1.2(WC/TA) + 1.4(RE/TA) + 3.3(EBIT/TA) + 0.6(MV Equity/TL) + 1.0(Sales/TA). WC = Working Capital, RE = Retained Earnings, EBIT = Earnings Before Interest & Taxes, MV = Market Value of Equity, TL = Total Liabilities, TA = Total Assets.
What do the Z-Score zones mean (Safe, Grey, Distress)?
Z > 2.99 = Safe Zone (low bankruptcy risk). 1.81–2.99 = Grey Zone (moderate risk, monitor closely). Z < 1.81 = Distress Zone (high probability of financial distress within 2 years). These thresholds apply to the Original model for publicly traded manufacturing companies.
How accurate is the Z-Score?
The Altman Z-Score achieves 80-90% accuracy in predicting bankruptcy up to 2 years in advance. Enron's Z-Score dropped from 3.2 to 1.1 in its final year — the model predicted it. Lehman Brothers showed distress signals 18 months before bankruptcy.
Can I use the Z-Score for private companies?
Yes. Use Model A (Z'-Score) for private manufacturing firms — it substitutes book value of equity for market value in the X4 ratio. Use Model B (Z''-Score) for non-manufacturing companies (retail, services, tech), which omits X5 (Sales/TA) due to industry variation.
What are Z-Score limitations?
The Z-Score is less reliable for startups (negative retained earnings, limited history), companies in different industries without model adjustment, and firms with atypical capital structures. It was developed on 1960s manufacturing data — use alongside other metrics.
