What Is the Quick Ratio?
The quick ratio is a liquidity metric that measures whether a company can pay its short-term liabilities using only its most liquid assets, excluding inventory.
The quick ratio is often called the acid-test ratio because it asks a harder question than the current ratio: if the company could not rely on selling inventory, would it still be able to cover bills due within the next year?
TL;DR: The quick ratio focuses on cash, near-cash assets, and receivables while leaving inventory out of the equation. A value above 1.0 is usually a good sign, but the right range depends heavily on the sector and business model. On ScreenerHub, it works well as a balance-sheet safety filter alongside debt, margin, and cash-flow metrics.
Why the Quick Ratio Matters
Not all current assets are equally liquid. Cash can be used immediately. Receivables may turn into cash within weeks. Inventory is different: it has to be sold first, sometimes at a discount, and sometimes not at all if demand weakens or products become obsolete.
That is why investors use the quick ratio when they want a more conservative view of short-term liquidity. A business might look fine on the current ratio because inventory is large, but the quick ratio reveals whether the company could still handle near-term obligations without depending on inventory turnover.
This matters most in cyclical businesses, wholesalers, retailers, manufacturers, and any company where inventory quality can change quickly. It is also useful when screening for financial resilience alongside debt-to-equity, free cash flow, and current ratio.
Quick ratio vs. current ratio
| Metric | What it includes | What it helps you judge |
|---|---|---|
| Current ratio | All current assets, including inventory | Broad short-term coverage |
| Quick ratio | Cash, marketable securities, and receivables only | Stricter short-term liquidity without inventory risk |
If both ratios look healthy, liquidity is probably solid. If the current ratio looks strong but the quick ratio is weak, inventory may be doing too much of the work.
How the Quick Ratio Is Calculated
The most common version of the formula is:
You may also see it written as:
Both formulas are trying to isolate the assets that can realistically become cash soon without relying on inventory sales.
Worked example
Imagine a fictional company, Harbor Parts Group:
| Item | Value |
|---|---|
| Cash and equivalents | $70M |
| Marketable securities | $20M |
| Accounts receivable | $85M |
| Inventory | $140M |
| Current liabilities | $150M |
| Quick assets | $175M |
| Quick ratio | 1.17 |
The company has $175 million of quick assets and $150 million of current liabilities:
That means Harbor Parts Group has $1.17 of highly liquid assets for every $1.00 of short-term obligations. Even if inventory took longer than expected to sell, the business would still have a reasonable liquidity cushion.
How to Interpret the Quick Ratio
In general, a quick ratio above 1.0 is considered healthy, because the company has enough liquid resources to cover short-term liabilities without depending on inventory. But like most balance-sheet metrics, the right number depends on the industry.
General benchmark guide
| Quick Ratio Range | What It Typically Signals |
|---|---|
| Below 0.8 | Tight liquidity; more dependence on inventory turnover or incoming cash |
| 0.8 - 1.0 | Borderline coverage; workable in some efficient business models |
| 1.0 - 1.5 | Often healthy for many non-financial companies |
| Above 1.5 | Strong short-term liquidity, though sometimes more cash than necessary |
Sector context matters
| Sector | Typical Quick Ratio | Why |
|---|---|---|
| Software / SaaS | 1.5 - 3.0 | High cash balances and little inventory often support strong ratios |
| Healthcare | 1.2 - 2.2 | Cash reserves and receivables are important, inventory is manageable |
| Industrials | 0.8 - 1.5 | Working capital is tied to receivables and operating cycles |
| Retail | 0.4 - 1.0 | Fast inventory turnover makes lower quick ratios more common |
| Consumer staples | 0.6 - 1.2 | Predictable sales can offset lower quick-asset coverage |
Context matters: A quick ratio of 0.7 may look weak in software, but it can be normal for a fast-turning retailer with stable daily cash receipts. Compare the metric to peers, not to a universal rule.
What a high quick ratio can mean
A very high quick ratio is not automatically bullish. It can mean the company is sitting on excess cash, collecting receivables slowly, or not reinvesting capital efficiently. That is why it helps to pair the quick ratio with returns-based metrics such as ROE or ROIC.
When the Quick Ratio Misleads
The quick ratio is useful, but it still has limitations.
1. Receivables are not the same as cash
Accounts receivable count as quick assets, but customers may pay late or default. A company can show a strong quick ratio while still facing cash pressure if receivables quality is poor.
2. It ignores timing within the year
The ratio is based on a balance-sheet snapshot. It does not show whether major payments are due next week or nine months from now, and it does not capture seasonal swings very well.
3. It can understate strong retailers
Some retail and grocery businesses intentionally run low quick ratios because inventory moves so fast that excluding it makes the business look weaker than it really is.
4. It says nothing about profitability
Short-term liquidity is helpful, but it does not tell you whether the business earns attractive returns or generates durable cash flow. A company can survive the next year and still be a poor long-term investment.
The Quick Ratio in a Stock Screener
On ScreenerHub, the quick ratio works best as a defensive filter. It helps you avoid companies that only look stable because inventory is inflating the current ratio.
Screener 1: Conservative balance-sheet check
| Filter | Setting |
|---|---|
| Quick Ratio | > 1.0 |
| Debt-to-Equity | < 1.0 |
| Free Cash Flow | Positive |
This screen looks for companies that have liquid assets, manageable leverage, and real cash generation. It is a solid starting point for defensive investors.
Screener 2: Quality industrials
| Filter | Setting |
|---|---|
| Sector | Industrials |
| Quick Ratio | > 0.9 |
| ROIC | > 10% |
| Gross Margin | > 20% |
This setup narrows the field to industrial businesses that can handle working-capital pressure while still earning decent returns on capital.
Screener 3: Safer value candidates
| Filter | Setting |
|---|---|
| P/E Ratio | 8 - 18 |
| Quick Ratio | > 1.0 |
| Earnings Growth | > 0% |
Adding a quick ratio filter can reduce the risk of buying a stock that looks cheap only because near-term balance-sheet stress has not fully shown up yet. That complements a disciplined value investing strategy.

Common Mistakes When Using the Quick Ratio
- Assuming inventory has no value at all. The quick ratio is intentionally conservative, but for some businesses inventory is highly liquid and operationally reliable.
- Treating 1.0 as a universal cutoff. Sector structure matters too much for that.
- Ignoring receivables quality. A company with weak collections can look safer than it really is.
- Using the ratio by itself. Liquidity without profitability or cash flow is not enough.
- Comparing companies with different operating cycles. Retail, software, and manufacturers should not be judged by the same benchmark.
Frequently Asked Questions
What is a good quick ratio for a stock?
For many non-financial companies, a quick ratio above 1.0 is generally seen as healthy. But the right range depends on the sector, the business model, and how predictable cash inflows are. A retailer may operate safely below 1.0, while a software company is often expected to be comfortably above it.
How is the quick ratio different from the current ratio?
The current ratio includes all current assets, including inventory. The quick ratio removes inventory and focuses on cash, marketable securities, and receivables. That makes the quick ratio a stricter test of short-term liquidity.
Can the quick ratio be negative?
Under normal circumstances, no. Quick assets and current liabilities are usually positive values, so the ratio is typically zero or higher. If you see a negative quick ratio, it usually points to a data problem or an unusual accounting classification.
Why is the quick ratio called the acid-test ratio?
It is called the acid-test ratio because it is meant to be a tougher test of liquidity. Instead of giving the company credit for inventory, it asks whether the business can handle short-term obligations using only its most liquid assets.
Should I use the quick ratio in a screener by itself?
Usually not. It works best with leverage, profitability, and cash-flow filters such as debt-to-equity, free cash flow, and ROE.
