Acid-Test Ratio (also known as the 'Quick Ratio'). Imagine a company hits a sudden, rough patch and needs cash fast. The acid-test ratio is the financial health check that reveals if it can pay its immediate bills without having to sell off its stock of goods, which is often difficult to do quickly at a fair price. It's a liquidity ratio—a measure of a company's ability to meet its short-term obligations using its most liquid, or “quick,” assets. Unlike the broader current ratio, the acid-test ratio deliberately excludes inventory from the calculation. This provides a more conservative and, for many value investors, a more realistic picture of a company's ability to survive a cash crunch. It answers a simple but crucial question: if revenue suddenly stopped, could the company cover its debts for the next year with the cash and near-cash assets it has on hand? A strong ratio suggests financial resilience, a hallmark of a well-managed business.

The logic is simple: subtract the least liquid current asset (inventory) from all current assets and see if what's left can cover all current liabilities.

The most common way to calculate the ratio is:

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

Let's break down the components:

  • Current Assets: These are all the assets a company expects to convert into cash within one year. This includes things like cash and cash equivalents, marketable securities, accounts receivable (money owed by customers), and, of course, inventory.
  • Inventory: This is the stock of raw materials, work-in-progress, and finished goods a company holds. It's excluded because it can't always be converted to cash quickly. In an emergency, a company might have to sell its inventory at a steep discount, so it's not a reliable source of immediate cash.
  • Current Liabilities: These are the company's debts and obligations due within one year, such as accounts payable (money owed to suppliers), short-term loans, and accrued expenses.

Sometimes you'll see the formula presented in a more direct way, which gets you to the same result:

  • Acid-Test Ratio = (Cash and Cash Equivalents + Marketable Securities + Accounts Receivable) / Current Liabilities

This version simply spells out the “quick assets” directly instead of starting with all current assets and subtracting inventory.

A number is just a number until you give it context.

  • A Ratio of 1.0 or Higher: This is the general benchmark for a healthy company. A ratio of 1.0 means the company has exactly €1 (or $1) of easily accessible cash for every €1 of short-term debt. A ratio of 1.5 means it has €1.50 for every €1.00 of debt, which provides a comfortable cushion.
  • A Ratio Below 1.0: This can be a red flag. It suggests the company is heavily reliant on selling its inventory or securing new financing to pay its bills. It might face a liquidity crisis if sales slow down unexpectedly.
  • A Very High Ratio (e.g., 3.0 or more): While it signals safety, an extremely high ratio could also indicate inefficiency. It might mean the company is hoarding cash that could be reinvested into the business for growth, used to pay dividends, or to buy back shares.

For followers of value investing, the acid-test ratio is more than just a box-ticking exercise.

  • Durability Over Glamour: A strong ratio is a sign of a durable, resilient business—one that can survive tough times. The legendary investor Benjamin Graham emphasized the importance of a strong financial position, and the acid-test ratio is a key indicator of this. It shows a company isn't living “paycheck to paycheck.”
  • Industry Matters: The ratio is most useful when comparing a company to its peers. A software company with no physical inventory will naturally have a high acid-test ratio, while a supermarket or car manufacturer will have a much lower one due to the nature of their business. Never compare apples to oranges.
  • Dig Deeper: Don't just accept the number. Look at the quality of the accounts receivable. If a large portion of receivables is owed by customers who are slow to pay, the company's real liquidity might be weaker than the ratio suggests. Check the company's history of writing off bad debt.

Let's look at a fictional company, “Chic Furnishings plc,” a high-end furniture retailer. Here are some figures from its balance sheet:

  • Current Assets: £800,000
  • Inventory (designer sofas, tables, etc.): £500,000
  • Current Liabilities: £250,000

Let's calculate the acid-test ratio:

  1. Step 1: Find the “quick assets.”
    • Quick Assets = Current Assets - Inventory
    • Quick Assets = £800,000 - £500,000 = £300,000
  2. Step 2: Calculate the ratio.
    • Acid-Test Ratio = Quick Assets / Current Liabilities
    • Acid-Test Ratio = £300,000 / £250,000 = 1.2

Interpretation: Chic Furnishings has an acid-test ratio of 1.2. This means it has £1.20 in liquid assets to cover every £1.00 of its immediate debts. Even if sales suddenly stopped, it appears to be in a solid position to meet its short-term obligations without having to hold a clearance sale on its expensive inventory.

The acid-test ratio is a powerful tool, but it's not perfect.

  • It's a Snapshot: The balance sheet only shows a company's position on a single day. A company could, for example, delay paying its suppliers to make its ratio look better at the end of a quarter.
  • Timing of Cash Flows: The ratio treats an account receivable due in 11 months the same as cash in the bank. However, that receivable can't be used to pay a bill that's due next week.
  • Receivables Quality: As mentioned, the ratio assumes all receivables will be collected in full and on time, which is rarely the case.
