Altman Z-Score Formula & Financial Health Calculator

What is the Altman Z-Score?

Developed by Professor Edward Altman in 1968, the Altman Z-Score is a quantitative model that assesses a company's probability of default. It is the result of sophisticated discriminant analysis, offering a more robust evaluation than single-ratio methods.

This model's strength lies in its multi-factor approach. It consolidates several key financial ratios into one comprehensive equation, preventing over-reliance on any single indicator when evaluating a company's credit risk.

Calculating the Altman Z-Score: Formula and Step-by-Step Guide

Let's examine Company Alpha to demonstrate the calculation. Assume Company Alpha provides the following financial data:

• Outstanding Shares: 1,000,000
• Share Price: $20
• Dividend Per Share: $0.50
• Annual Sales: $10,000,000
• EBIT: $4,000,000
• Net Income: $1,000,000
• Accounts Receivable: $200,000
• Accounts Payable: $100,000
• Inventory: $300,000
• Total Assets: $50,000,000
• Total Liabilities: $20,000,000

The calculation involves five distinct ratios across six clear steps.

Step 1: Net Working Capital to Total Assets Ratio

This ratio evaluates short-term liquidity. First, calculate Net Working Capital (NWC):

NWC = Accounts Receivable + Inventory - Accounts Payable

For Company Alpha:

NWC = $200,000 + $300,000 - $100,000 = $400,000

Then, calculate the NWC/TA Ratio:

NWC/TA Ratio = $400,000 / $50,000,000 = 0.008

Step 2: Retained Earnings to Total Assets Ratio

This measures accumulated profitability. Calculate Retained Earnings (RE):

RE = Net Income - (Dividend Per Share * Shares Outstanding)

For Company Alpha:

RE = $1,000,000 - ($0.50 * 1,000,000) = $500,000

Then, calculate the RE/TA Ratio:

RE/TA Ratio = $500,000 / $50,000,000 = 0.01

Step 3: EBIT to Total Assets Ratio

This assesses operating profitability. The calculation is straightforward:

EBIT/TA Ratio = EBIT / Total Assets

For our example:

EBIT/TA Ratio = $4,000,000 / $50,000,000 = 0.08

Step 4: Market Value of Equity to Total Liabilities Ratio

This indicates financial leverage. Calculate Market Value of Equity (MVE):

MVE = Share Price * Shares Outstanding

For Company Alpha:

MVE = $20 * 1,000,000 = $20,000,000

Then, calculate the MVE/TL Ratio:

MVE/TL Ratio = $20,000,000 / $20,000,000 = 1.0

Step 5: Sales to Total Assets Ratio

This ratio measures asset efficiency.

Sales/TA Ratio = Sales / Total Assets

For Company Alpha:

Sales/TA Ratio = $10,000,000 / $50,000,000 = 0.2

Step 6: Compute the Final Altman Z-Score

With all ratios ready, apply the full Altman Z-Score formula:

Z = 1.2*(NWC/TA) + 1.4*(RE/TA) + 3.3*(EBIT/TA) + 0.6*(MVE/TL) + 1.0*(Sales/TA)

For Company Alpha:

Z-Score = (1.2*0.008) + (1.4*0.01) + (3.3*0.08) + (0.6*1.0) + (1.0*0.2) = 1.0876

Interpreting Your Altman Z-Score Results

A higher Altman Z-Score generally indicates a lower risk of bankruptcy. To provide clear context, standard interpretation zones are used:

• Score Below 1.81: High probability of financial distress.
• Score Above 3.00: Low probability of default, indicating a financially healthy company.
• Score Between 1.81 and 3.00: The "gray zone," requiring further detailed financial analysis.

Remember, prudent investment decisions should never rely on a single metric. Always corroborate findings with other financial analyses and industry comparisons.
