Long before a company formally fails, its financial statements usually whisper the trouble. The Altman Z-score is the best-known attempt to turn that whisper into a single, comparable number — a distillation of five ratios that has flagged distress a year or two ahead for decades. It is not magic, but it is one of the cleanest examples of forensic analysis compressed into one figure.
Five ratios, one number
Edward Altman’s 1968 model blends five ratios, each weighted, each capturing a different facet of survival: liquidity (working capital / total assets), cumulative profitability (retained earnings / total assets), operating return (EBIT / total assets), market solvency (market value of equity / total liabilities) and efficiency (sales / total assets). The weighted sum is the Z-score, and where it lands tells you which zone the company sits in.
Enter the five inputs from a company’s statements and market cap, and watch the Z-score and its zone update — then change one ratio to see which part of the balance sheet is doing the damage.
| Z-score | Zone | What it suggests |
|---|---|---|
| Above 2.99 | Safe | Low near-term distress risk |
| 1.81 – 2.99 | Grey | Some concern — watch the trend |
| Below 1.81 | Distress | High risk of financial trouble |
A manufacturer’s Altman Z-score has fallen from 3.4 to 1.9 over three years but is still above the 1.81 distress line. What is the right read?
Company failhone se bahut pehle uske numbers fusfusaane lagte hain. Altman Z-score paanch ratio ko ek number mein nichod deta hai — 2.99 ke upar safe, 1.81 se neeche khatra, beech mein grey. Asli baat: number se zyada trend — 3.4 se 2.2 aana hi warning hai, line cross karne se pehle. Banks pe yeh formula nahi chalta. Kam score dekha toh debt aur cash-flow kholo — yeh screen hai, faisla nahi.
- The Altman Z-score combines five weighted ratios into one distress-risk number.
- Above 2.99 is safe, 1.81–2.99 is grey, below 1.81 signals high distress risk (manufacturing model).
- The zone and the year-on-year trend matter more than the exact figure.
- It does not work for banks and insurers, and flatters asset-light and young firms.
- Treat a weak score as a screen that sends you to the debt and cash-flow detail, not a verdict.

Common questions
Short, direct answers to what people ask about this topic.
- what is the altman z-score
- The Altman Z-score is a formula that combines five financial ratios into a single number estimating how close a company is to bankruptcy. Devised by Edward Altman in 1968, it weights measures of liquidity, cumulative profitability, operating efficiency, market solvency and asset turnover, and produces a score that falls into a safe zone, a grey zone or a distress zone. It was built to give lenders and analysts a quick, quantitative read on financial health rather than relying on a subjective judgement of whether a firm might fail.
- what is a safe altman z-score
- For a traditional manufacturing company, a Z-score above 2.99 is the safe zone, between 1.81 and 2.99 is a grey zone of some concern, and below 1.81 signals a high risk of financial distress. Those thresholds come from the original model built on manufacturers; variants of the formula use different cut-offs for non-manufacturers and emerging markets. The direction and trend matter as much as the level — a score falling year on year toward the grey zone is a warning even before it crosses a threshold.
- how do you calculate the altman z-score
- The classic Z-score adds five weighted ratios: 1.2 times working capital to total assets, 1.4 times retained earnings to total assets, 3.3 times EBIT to total assets, 0.6 times the market value of equity to total liabilities, and 1.0 times sales to total assets. Each ratio captures a different dimension of health — liquidity, accumulated profit, operating return, market solvency and efficiency — and the weighted sum is the Z-score. The inputs all come from the balance sheet, income statement and market capitalisation, so it can be computed for any listed company.
- is the altman z-score reliable for predicting bankruptcy
- The Altman Z-score has a good historical record at flagging distress a year or two ahead for traditional industrial firms, which is what it was built on, but it is a screen, not a crystal ball. It works poorly for financial companies like banks and insurers, whose balance sheets are structurally different, and it can mislead for asset-light businesses and young growth companies with little retained earnings. Treat a weak score as a prompt to investigate the debt, cash flow and covenants — not as a verdict on its own.
