Acid-Test Ratio

The Acid-Test Ratio, also known as the Quick Ratio or the Liquid Ratio, is a financial ratio used to assess a company’s short-term liquidity and ability to meet its immediate obligations without relying on the sale of inventory. It provides a more stringent measure of liquidity than the current ratio by excluding inventory from current assets.

The formula to calculate the Acid-Test Ratio is:

Acid-Test Ratio = (Current Assets – Inventory) / Current Liabilities


  • Current Assets are assets that are expected to be converted into cash or used up within one year.
  • Inventory represents the value of goods held for sale or raw materials held for production.
  • Current Liabilities are obligations due within one year.

By excluding inventory from the equation, the Acid-Test Ratio focuses on the company’s most liquid assets, which are typically cash, cash equivalents, accounts receivable, and short-term investments. These assets can be quickly converted into cash or used to settle short-term liabilities.

Interpretation of the Acid-Test Ratio:

Ideal Ratio: Generally, a higher Acid-Test Ratio is preferred, as it indicates a stronger ability to meet short-term obligations without relying on inventory sales. A ratio of 1 or higher is considered acceptable, as it suggests that the company can cover its current liabilities with its most liquid assets.

Low Ratio: If the Acid-Test Ratio is less than 1, it indicates that the company may have difficulty meeting its short-term obligations without relying on the sale of inventory. This could be a concern if inventory turnover is slow or if there are challenges in converting receivables into cash quickly.

Comparison with Current Ratio: Comparing the Acid-Test Ratio to the Current Ratio provides insights into the impact of inventory on the company’s liquidity. If the Acid-Test Ratio is significantly lower than the Current Ratio, it suggests that inventory is a significant portion of current assets and may require careful management.

Industry and Historical Comparison: The Acid-Test Ratio should be compared to industry benchmarks and the company’s historical performance to evaluate its liquidity position relative to peers and its own past performance.

It is essential to recognize that the Acid-Test Ratio is just one of many financial metrics used to assess a company’s financial health and liquidity. While a high ratio indicates strong short-term liquidity, it does not provide a complete picture of a company’s overall financial strength or long-term viability. Therefore, it is crucial to consider multiple financial ratios and other qualitative factors when evaluating a company’s financial health.
