Altman Z Score: One of the most dreaded words in the world of Business and Investing is, “Bankruptcy”. This is that phrase that signifies that the company is not running profitably and is not able to meet its obligations and can sometimes be also debt-ridden. And when this situation arises, the company has nowhere to go but to shut itself down.
But is it actually possible to be able to forecast and foresee as to what is the likelihood of a company going Bankrupt before the event actually transpires?
And if one is able to do so, it would be so easy for the investors to understand which company is worth investing in for the long term and most importantly which are the ones that should be avoided.
Introducing Altman Z Score
What is Altman Z score?
According to Investopedia, “The Altman Z-score is the output of a credit-strength test that gauges a publicly traded manufacturing company’s likelihood of bankruptcy.”
Altman Z is a method of finding whether a company (especially in the field of Manufacturing) is heading towards bankruptcy. It is a method of gauging the solvency status of the company.
Various factors like profitability, liquidity, solvency and various financial ratios are given due consideration while calculating it.
Who developed the Altman Z score?
The concept of Altman Z was developed by Professor Edward Altman in 1967, and it went on to be published in 1968. The Altman Z was tested by Professor Edward in various phases:
- During the period of 1969 to 1975, he evaluated 86 companies in distress.
- Over the next 20 years, he evaluated 110 companies in distress
- And finally, between 1996 to 1999, he evaluated another 120 companies.
And during this study of 30 years, the Altman Z had an incredible accuracy of nearly 90% in finding the bankruptcy status of the companies evaluated.
How to Calculate the Altman Z score?
The following is the simple formula for calculating the Altman Z:
Altman Z Score = 1.2A + 1.4B + 3.3C + 0.6D + 1.0E
Where,
- A = Working Capital/Total Assets
- B = Retained Earnings/Total Assets
- C = EBIT/Total Assets
- D = Market value of Equity/Total Liabilities
- E = Sales/Total Assets
From the above Calculation, the value that is generated tells us a lot about the ability of the company to be able to sustain the in the current business environment.

Now if you look at the image above, we have three zones marked as Orange, Grey and Green.
- Now, if the company under consideration falls in the Orange Zone (Distress Zone), it is generally a sign of danger, as the company has scored less than 1.8 on Altman Score. Any score less than 1.8 generally means that the company is heading towards bankruptcy in near future.
- Say, if the company under consideration falls in the Grey Zone, it is generally an indication that the company has scored between 1.8 to 3 on the Altman scale. There are moderate chances of the company filing for Bankruptcy. The company can be considered to be relatively safe
- And, if the company falls in the green zone (safe zone), it generally means that the company is very safe and financially sound. These kinds of companies are generally good investment proposition companies.
A simple tip for Investors
If an investor is looking to use Altman Z for investment decision purposes, he could use the simple strategy of going long in the stocks which have an Altman Z score of 3 or more and short/sell those shares that have a score of less than 1.8.
To Conclude
The Altman Z is a method of finding whether a company (especially in the field of manufacturing) is headed towards bankruptcy. A company with a score of 3 or more is generally considered to be very safe and reliable, but if the score is below 1.8, then it should set the alarm bells ringing.
