Zeta model

Zeta model

People enjoy making predictions about the weather or the direction of a company. However, in order to make a good prediction you need to do more than just educated speculation. They necessitate the examination of various scenarios and the corresponding calculations. 

A multivariate numerical assessment called Altman’s zeta score model forecasts the likelihood that a company will fail in the following two years. The approach, developed by Edward Altman in 1968, uses different financial ratios based on the company’s balance sheet to distinguish between non-bankrupt and bankrupt companies. 

What is the zeta model? 

The Zeta Model calculates the probability that a publicly traded firm will fail in the next two years. The model’s output, known as the company’s Z-score (also known as zeta score), is a fair predictor of upcoming bankruptcy. 

Professor Edward Altman of New York University (NYU) created the zeta model in 1960, intending to calculate the likelihood that a public firm will go bankrupt within two years. The model’s output, known as the company’s z-score (Z), is a reasonably reliable predictor of the future. 

Understanding zeta model 

The zeta model calculates weights for different numerical variables based on their importance to the business’s long-term success. The ratings for the market value of equity over total liabilities and sales over total assets are the least valuable to a corporation.  

Working capital and retained earnings over total assets get mid-range ratings. The most significant variable is earnings before interest and taxes as a percentage of total assets. 

The zeta model produces a number to rate the firm after the necessary numbers are entered. The closer a company gets to bankruptcy, the lower the number. Generally, a score of 1.8 or lower indicates that a company is in difficulty, while a score of 3.0 or higher indicates that the organization is secure. According to the company’s regulations and market swings, a score between 1.8 and 3.0 is considered a danger zone; it might go either way. 

Benefits of zeta model 

The financial health of a corporation can be quantified using the zeta model. The z-score highlights the aspects that affect a company’s financial health and identifies new trends that point to the improvement or deterioration of the financial condition. 

Business managers use the z-score as a crucial instrument to evaluate financial well-being. It assists managers in coordinating corporate strategies with decisions about capital allocation and offers lenders and equity capital providers clarity regarding the economic situation.  

Managers of businesses use the z-score to obtain credit and acquire capital. The z-score is useful for showing investors and bankers that a business plan is sound and creditworthy. 

The z-score is based on actual financial data obtained from the commercial enterprise’s operating performance. It stays away from the prejudices brought on by subjective evaluations, conflicts of interest, brands, and big business.  

No theoretical presumptions or market inputs used in the z-score are included in the company’s financial records. This gives z-score users a consistent perspective on and comprehending a company’s financial condition. 

Formula of zeta model 

The 10-K report’s data calculate the z-score model based on five important financial ratios. It improves the model’s accuracy when calculating a company’s financial health and the likelihood of bankruptcy. 

This is how the zeta model formula is expressed: 

​ζ = 1.2A + 1.4B + 3.3C + 0.6D + 1.0E 


  • Altman’s z-score is denoted by zeta () 
  • The working capital to total asset ratio is A 
  • The retained earnings to total assets ratio is B 
  • The total asset to profits before interest and taxes ratio is C 
  • The market value of equity to all liabilities is divided by this number, D 
  • Total sales divided by total assets equals the ratio E 

Example of zeta model 

Chinese manufacturer Belta makes automobile engines. Its has an operating history of around 20 years. It can now increase both its workforce and output due to its success. But as a recent loan was obtained to allow for automation, investors want to know how the company is doing. 

Its working capital is $4,200,000, and total assets are valued at $3,500,000. It has $5,000,000 in liabilities and $800,000 in retained earnings. $6,500,000 is the earnings before interest and tax. Sales come to $8,300,000, while the equity is worth is $7,000,000. 

The Altman z-score for Belta is calculated as follows:  

The formula for the Altman z-score is: 

=(1.2 x A) + (1.4 x B) + (3.3 x C) + (0.6 x D) + (0.999 x E) 

= (1.2 x (4,200,000 / 3,500,000)) + (1.4 x (800,000 / 3,500,000)) + (3.3 x (6,500,000 / 3,500,000)) + (0.6 x (7,000,000 / 5,000,000)) + (0.999 x (8,300,000 / 3,500,000)) 

= (1.2 x 1.2) + (1.4 x 0.229) + (3.3 x 1.857) + (0.6 x 1.4) + (0.999 x 2.371) (0.999 x 2.371) 

z-score for Altman= 11.097 

Here, investors can rest calmly and unwind while anticipating greater gains. Belta scored 11.097, placing it squarely in the safe area. 

Frequently Asked Questions

The zeta model provides a single number, the z-score (sometimes known as the zeta score), indicating how likely it is that a company will fail in the following two years. A corporation is more likely to go bankrupt with a lower z-score. 

Interchange costs, or the price a merchant must pay to process your payment, is how the Zeta model generates revenue from card transactions. Zeta receives a share of the interchange charge, and your bank also gets a portion. 

Evaluating firms is superior to using just one ratio since it combines the effects of several other factors, including assets, profits, and market value. As a result, the zeta model is frequently used by creditors and lenders to assess the risk involved in providing credit to clients and borrowers. 

A new business or an emerging business entity with modest earnings cannot use the zeta model. When the company is contrasted to its database, the zeta model predicts the likelihood of failure. 

Approximately 84% of businesses that declared bankruptcy between 2014 and 2019 were found to have a notable Altman z-score three years before the bankruptcy filing. 

Predictions of financial trouble cannot be guaranteed, and the Altman z-score is not a reliable indicator of impending bankruptcy or insolvency. But z-scores are an effective statistic for offering a neutral assessment of a company’s financial health.
