1. The Critical Concept of Liquidity
Liquidity measures a company’s ability to pay its short-term obligations as they fall due. A business can be highly profitable on paper but still go bankrupt if it runs out of cash to clear immediate liabilities (such as supplier bills or wages).
2. Core Liquidity Formulas
  • Current Ratio (Working Capital Ratio): Measures the general availability of short-term resources to cover short-term debts.

  • Current Ratio (Working Capital Ratio)
    “Current Ratio” = “Current Assets”/”Current Liabilities”

  • Acid Test Ratio (Quick Ratio): A stricter liquidity test that strips out inventory from current assets. Inventory is excluded because it can be slow or difficult to convert into cash during a liquidity squeeze.

Acid Test Ratio = (Current Assets − Inventory) ÷ Current Liabilities

Standard Benchmark: A ratio of 1.0 or higher shows a safe cash position.

3. Over-Liquidity Risk
While low liquidity signals insolvency risks, excessively high ratios (e.g., a current ratio of 4.0) suggest inefficiency. It indicates the business is holding too much idle cash, uncollected debt, or slow-moving inventory that could be better reinvested to generate growth.
