Ratios: Acid Test Ratio

The Acid-Test Ratio, also known as the Quick Ratio, is a financial metric used to assess a company’s short-term liquidity and ability to pay its immediate obligations without relying on the sale of inventory. It is a more conservative measure of liquidity than the current ratio because it excludes inventory, which may not be as easily convertible to cash. The formula for calculating the Acid-Test Ratio is as follows:

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


Here’s a step-by-step guide on how to calculate the Acid-Test Ratio:

  1. Gather the Necessary Financial Information:
    • Obtain the company’s financial statements, which include the balance sheet (also known as the statement of financial position). The balance sheet provides the values of current assets, inventory, and current liabilities needed for the calculation.
  2. Identify Current Assets:
    • From the balance sheet, locate the current assets. These are assets that are expected to be converted into cash or used up within one year or one operating cycle, whichever is longer. Common current assets include cash, accounts receivable, marketable securities, and prepaid expenses.
  3. Determine Inventory:
    • Identify the inventory value on the balance sheet. Inventory includes goods held by a company for sale in the ordinary course of business. It may include raw materials, work-in-progress, and finished goods.
  4. Identify Current Liabilities:
    • Locate the current liabilities on the balance sheet. These are obligations expected to be settled within one year or one operating cycle, whichever is longer. Common current liabilities include accounts payable, short-term loans, and accrued expenses.
  5. Calculate the Acid-Test Ratio:
    • Use the formula mentioned earlier to calculate the Acid-Test Ratio. Subtract the value of inventory from the total current assets and then divide the result by the total current liabilities.
    Acid-Test Ratio = (Current Assets – Inventory) / Current Liabilities
  6. Interpret the Result:
    • The result of the Acid-Test Ratio calculation represents the company’s ability to meet its short-term obligations with its most liquid assets, excluding inventory. A ratio greater than 1 indicates that the company has enough quick assets to cover its current liabilities, which is generally considered a sign of good liquidity. A ratio less than 1 suggests potential liquidity issues.

It’s important to note that while the Acid-Test Ratio provides valuable insights into a company’s short-term liquidity, it is just one of many financial metrics used for financial analysis. It should be considered in conjunction with other financial ratios and factors to gain a comprehensive understanding of a company’s financial health.
