Understanding the collateral ratio: calculation, interpretation, and practical application

▶ The importance of the guarantee ratio in financial assessment

When analyzing a company’s financial health, the guarantee ratio emerges as one of the most relevant indicators for financial institutions and investors. This coefficient, also known as the solvency index, allows us to assess whether a company has sufficient assets and rights to back its entire set of monetary obligations.

Unlike other indicators that focus exclusively on the short term, the guarantee ratio covers the entire debt horizon. While the liquidity ratio only considers assets and liabilities due in less than a year, this ratio integrates the entire organizational patrimonial structure without time restrictions.

▶ The simplified calculation formula

Obtaining this indicator is straightforward and accessible. It does not require complex calculations or advanced accounting knowledge. The methodology is as follows:

Guarantee ratio = (Total Assets) / (Total Liabilities)

For companies reporting under Anglo-Saxon standards, we will take the “Total Assets” field divided by “Liabilities.”

Let’s look at practical applications:

With Tesla Inc., using its most recent balance sheets:

• Total Assets: $82.34 billion
• Total Liabilities: $36.44 billion
• Result: 2.259

Contrast this with Boeing in its latest quarter:

• Total Assets: $137.10 billion
• Total Liabilities: $152.95 billion
• Result: 0.896

The figures reveal radically different situations. Tesla exhibits a stronger position while Boeing shows vulnerability. But what exactly do these numbers mean?

▶ Deciphering the interpretation ranges

The guarantee ratio makes sense when contextualized within reference intervals:

Less than 1.5: The company experiences a critical level of debt, significantly increasing its insolvency risk.

Between 1.5 and 2.5: This range is considered optimal. Organizations operating within these parameters maintain healthy financial balance and prudent patrimonial management.

Greater than 2.5: Could indicate inefficiency in the use of financial leverage, with underutilized assets and excessive dependence on equity.

▶ Sector context determines validity

However, these metrics are indicative. Each industry has its own characteristics that modify interpretation.

Tesla, seemingly overcapitalized with its high ratio, actually reflects a business model intensive in research and development. Tech companies require substantial capitalization because their investments can generate exponential returns or total losses. The preference for internal financing over external debt protects against insolvency risks.

Boeing experienced significant deterioration post-pandemic when aircraft demand plummeted, showing how macroeconomic events can turn previously positive ratios into warning signals.

▶ Advantages of this financial indicator

The guarantee ratio offers multiple analytical strengths:

• Works uniformly regardless of company size, applicable to small, medium, and large enterprises without distortion of meaning

• Its calculation is simple, accessible even for investors without deep accounting training

• Has predictive accuracy: companies that later went bankrupt previously showed this ratio deteriorated

• When combined with other solvency coefficients, it identifies vulnerable positions susceptible to speculative operations

▶ Case study: The collapse of Revlon

In 2022, Revlon declared insolvency after poor management. Let’s examine its figures as of September 30:

• Total Liabilities: $5.02 billion
• Total Assets: $2.52 billion
• Resulting guarantee ratio: 0.5019

This critical metric anticipated the catastrophe. Not only did it lack sufficient patrimonial backing, but the trend was regressive: obligations increased while assets decreased.

▶ Conclusion: An indispensable tool

The guarantee ratio is a fundamental barometer of business viability. Its longitudinal analysis—observing its annual evolution—provides visibility into financial trends.

The most effective strategy combines this indicator with the liquidity ratio. Together, they offer a dual perspective: immediate payment capacity and structural financial sustainability. For investors evaluating opportunities, both ratios provide unequivocal signals about management quality and the stability of their capital’s destination.
