Liquidity Ratios: Current Ratio and Acid-Test Ratio
- Liquidity ratios show whether a business has enough money to pay its bills.
- If a company runs out of cash, it can’t pay suppliers, employees, or rent, even if it’s making profits on paper.
- That’s why liquidity is just as important as profitability, a business that can’t pay its debts when they’re due is in trouble.
Liquidity Ratios
Liquidity Ratios measure a company's ability to meet short-term financial obligations.
The Current Ratio
Current Ratio
The Current Ratio is a liquidity ratio that measures a company's ability to pay short-term obligations using its current assets.
- The current ratio checks if a business has enough current assets (things that can be quickly turned into cash, like cash itself, accounts receivable, and inventory),
- To cover its current liabilities (short-term debts like supplier payments and loans due soon).
- A ratio above 1 indicates that a company has more current assets than liabilities, suggesting good short-term financial health.
Current Ratio Formula
$$\text{Current Ratio} = \frac{\text{Current Assets}}{\text{Current Liabilities}}$$
- A business with €20 million in current assets and €10 million in current liabilities has a current ratio of 2:1.
- This means it has €2 of current assets for every €1 of short-term debt—a solid financial position.
What to Watch Out For
- In the past, a 2:1 ratio was seen as ideal, but today many businesses operate efficiently with 1.6:1.
- If the current ratio is too high, say 3:1 or more, it might mean the company is holding too much cash or inventory instead of investing it wisely.
- Fast-food chains (like McDonald’s) operate with low current ratios because they sell fast and get paid in cash.
- On the other hand, manufacturers often have higher current ratios because they keep more inventory on hand.
The Acid-Test (Quick) Ratio: A Stricter Measure
Acid Test Ratio
The Acid Test Ratio, also known as the Quick Ratio, measures a company's ability to meet short-term liabilities using its most liquid assets (excluding inventory).
- The acid-test ratio, also called the quick ratio, is a stricter test.
- It removes stock from current assets because inventory can take time to sell, meaning it’s not as “liquid” as cash.
- Understand that $$\text{Quick Assets = Current Assets - Inventory - Prepaid Expenses}$$
A ratio of 1 or more is generally considered healthy.
Acid Test Formula
$$\text{Acid-Test Ratio} = \frac{\text{Current Assets} - \text{Inventory}}{\text{Current Liabilities}}$$
A business with €12 million in current assets, €4 million in stock, and €6 million in current liabilities would have an acid-test ratio of 1.33:1.
Key Differences from the Current Ratio
- A high current ratio but a low acid-test ratio means the company is relying too much on inventory to stay liquid.
- A strong acid-test ratio (close to 1:1) means the company can pay its short-term debts without selling stock.
Industry Norms
- Retailers often have lower acid-test ratios (as low as 0.4:1) because they rely on selling stock quickly.
- Manufacturing businesses aim for around 1:1 because they need to cover short-term costs.
- Don’t confuse liquidity with profitability.
- A company can have plenty of cash but still be unprofitable, or profitable but unable to pay its debts on time.
Interpreting Liquidity Ratios
- A single ratio doesn’t tell the full story.
- The best way to analyze liquidity is to compare a company’s ratios over time and against competitors.
- Factors that affect liquidity ratios include:
- Industry Type – Retailers often have lower liquidity ratios than manufacturers.
- Business Model – Just-in-time businesses hold fewer assets, reducing their current ratio.
- Economic Conditions – During a recession, businesses may hoard cash, increasing their liquidity ratios.
Always justify liquidity ratio conclusions using actual business conditions rather than just stating “higher is better.”
Real World Examples
| Company | Industry | Current Ratio | Acid-Test Ratio |
|---|---|---|---|
| Microsoft Corp. | Technology | 2.5:1 | 2.3:1 |
| Walmart Inc. | Retail | 0.8:1 | 0.5:1 |
| Pfizer Inc. | Pharmaceuticals | 1.9:1 | 1.6:1 |
- Microsoft Corp.: With a high current ratio of 2.5:1 and an acid-test ratio of 2.3:1, Microsoft demonstrates a strong liquidity position, indicating it can comfortably meet short-term obligations without relying heavily on inventory.
- Walmart Inc.: The current ratio of 0.8:1 and acid-test ratio of 0.5:1 reflect retail industry norms, where companies often operate with lower liquidity ratios due to rapid inventory turnover and favorable credit terms with suppliers.
- Pfizer Inc.: A current ratio of 1.9:1 and an acid-test ratio of 1.6:1 suggest that Pfizer maintains a healthy liquidity position, ensuring it can meet short-term liabilities while managing substantial inventories typical in the pharmaceutical industry.
Always compare liquidity ratios to industry benchmarks and past performance to get a clearer picture of a business's financial health.
- Don't assume a high current ratio automatically means strong liquidity.
- Always check the acid-test ratio to see if inventory is skewing the results.
