A company reports ₹320 crore of current assets against ₹200 crore of current liabilities — a healthy-looking current ratio of 1.6. Then you learn ₹250 crore of those assets is unsold inventory sitting in a warehouse. If bills came due next week, that inventory would not help. The quick ratio is built to expose exactly this.
What is the Quick Ratio?
The quick ratio, also called the acid test ratio, measures whether a company can cover its short-term obligations using only assets that convert to cash quickly — deliberately excluding inventory.
Quick Ratio = (Current Assets − Inventory) ÷ Current Liabilities
Or built up from the components directly:
Quick Ratio = (Cash + Marketable Securities + Receivables) ÷ Current Liabilities
The name “acid test” comes from the old assayer’s test for gold — a quick, decisive check on whether something is genuine.
Why Inventory Gets Excluded
Inventory is a current asset on paper, but converting it to cash requires several things to go right:
- Someone has to want to buy it
- At roughly the value it is carried at
- Within a useful timeframe
- And then actually pay for it
None of that is guaranteed. Fashion inventory goes out of season. Electronics are superseded. Perishables expire. Specialised industrial components may have exactly one potential buyer. In a genuine cash crunch — the situation this ratio is designed for — inventory is usually sold at a discount, if at all.
Prepaid expenses are also excluded, since they cannot be converted to cash at all.
Worked Example — Where the Two Ratios Diverge
| Item | Company A | Company B |
|---|---|---|
| Cash | ₹80 crore | ₹15 crore |
| Receivables | ₹140 crore | ₹120 crore |
| Inventory | ₹100 crore | ₹185 crore |
| Total current assets | ₹320 crore | ₹320 crore |
| Current liabilities | ₹200 crore | ₹200 crore |
| Current ratio | 1.60 | 1.60 |
| Quick ratio | 1.10 | 0.68 |
The current ratio says these two companies are identical. The quick ratio says they are not remotely similar. Company A can cover its short-term obligations from cash and receivables alone. Company B cannot — it would have to liquidate inventory, in a hurry, probably at a loss.
A large gap between the two ratios is the finding. It means the company’s apparent liquidity rests on stock it still has to sell.
How to Read the Number
| Quick ratio | Interpretation |
|---|---|
| Below 0.5 | Heavily dependent on inventory or fresh borrowing to meet obligations |
| 0.5 – 1.0 | Tight; acceptable in fast-turnover retail and FMCG |
| Around 1.0 | Can cover short-term obligations without touching inventory |
| 1.0 – 2.0 | Comfortable position |
| Above 2 | Very liquid — check whether cash is being deployed productively |
A quick ratio of 1 is the conventional comfort threshold, but as with every liquidity measure, sector norms matter more than any universal figure.
Sector Context
| Sector | Typical quick ratio | Reason |
|---|---|---|
| IT services | High | Almost no inventory — current and quick ratios are nearly identical |
| FMCG | Low, often under 1 | Inventory-heavy, but it turns over rapidly and sells for cash |
| Retail | Low | Same reason — high stock, but fast conversion and supplier credit |
| Pharmaceuticals | Moderate | Significant inventory with longer shelf life |
| Capital goods | Low to moderate | Large work-in-progress inventory tied to long projects |
| Jewellery | Very low | Inventory is the business — gold stock dominates the balance sheet |
A jewellery retailer with a quick ratio of 0.3 is not necessarily in trouble. Its inventory is gold, which is genuinely liquid and holds value — one of the few cases where excluding inventory arguably understates the true position. Judgement about what kind of inventory is being excluded matters.
The Receivables Caveat
The quick ratio removes inventory but keeps receivables, and receivables are not automatically reliable either. Money owed by a customer who is themselves in difficulty may never arrive.
Two checks worth running alongside:
- Are receivables growing faster than revenue? If sales rise 12% and receivables rise 40%, collection quality is deteriorating.
- What is the ageing profile? Annual reports disclose how much has been outstanding beyond six months. A rising proportion of old receivables is a warning the ratio alone will not show.
For the very strictest test, some analysts use the cash ratio — cash and equivalents divided by current liabilities — which strips out receivables too. It is deliberately conservative and rarely above 0.5 even for healthy companies.
The Three Liquidity Ratios Compared
| Current Ratio | Quick Ratio | Cash Ratio | |
|---|---|---|---|
| Includes inventory | Yes | No | No |
| Includes receivables | Yes | Yes | No |
| Strictness | Least strict | Moderate | Most strict |
| Typical comfort level | Around 1.5–2 | Around 1 | Around 0.2–0.5 |
| Best used for | General liquidity check | Inventory-heavy businesses | Companies under stress |
Reading all three together is more revealing than any one. Where they diverge sharply tells you which asset class the company’s liquidity actually depends on.
Key Takeaways
- Quick Ratio = (Current Assets − Inventory) ÷ Current Liabilities
- Also called the acid test ratio — a stricter version of the current ratio
- Inventory is excluded because it may be slow, discounted or impossible to sell in a crunch
- Around 1.0 is the conventional comfort threshold
- A large gap between current and quick ratio means liquidity depends on unsold stock
- FMCG, retail and jewellery operate healthily below 1 due to fast or genuinely liquid inventory
- Receivables are included but are not automatically reliable — check ageing and growth
- Read current, quick and cash ratios together for the full picture
Frequently Asked Questions (FAQ)
Q: What is the quick ratio in simple terms?
The quick ratio checks whether a company could pay its short-term bills using only cash and money owed to it, without needing to sell any inventory. A ratio of 1 means it has just enough of these fast-converting assets to cover what it owes within the year.
Q: What is the quick ratio formula?
Quick Ratio = (Current Assets − Inventory) ÷ Current Liabilities. Some analysts also subtract prepaid expenses, since these cannot be converted to cash. All figures come from the balance sheet.
Q: Why is the quick ratio called the acid test?
The name comes from the historical acid test used to verify whether metal was genuinely gold — a fast, decisive check. The financial ratio serves the same purpose: a strict, no-benefit-of-the-doubt test of whether a company can meet its immediate obligations.
Q: What is a good quick ratio?
Around 1.0 is generally considered comfortable, meaning liquid assets match short-term liabilities. But sector norms matter more — FMCG and retail companies routinely operate below 1 because their inventory converts to cash quickly, while IT companies typically run well above it.
Q: What is the difference between current ratio and quick ratio?
The current ratio includes inventory among current assets; the quick ratio excludes it. When the two ratios are close, the company holds little inventory. When they diverge sharply, its apparent liquidity depends heavily on selling stock it still holds.
Q: Can a company have a good current ratio but a poor quick ratio?
Yes, and this is exactly what the quick ratio is designed to reveal. A company holding large amounts of slow-moving inventory can show a comfortable current ratio while being unable to meet obligations without liquidating that stock, often at a discount.
Q: What is the cash ratio?
The cash ratio is the strictest liquidity measure — cash and equivalents divided by current liabilities, excluding both inventory and receivables. It rarely exceeds 0.5 even for healthy companies and is mainly used when assessing businesses under financial stress.
