The current ratio and the quick ratio both ask the same question: can this company pay the bills due in the next year? The difference is what each counts as money available to pay them. The current ratio counts every current asset, including inventory. The quick ratio keeps only the assets that turn into cash fast, so it is the stricter test. Use both together, and read them against a company's own history and its industry.
TL;DR
- Current ratio = total current assets ÷ total current liabilities. It counts everything the company expects to turn into cash within a year.
- Quick ratio = cash, marketable securities and receivables ÷ total current liabilities. It leaves out inventory and prepaid expenses.
- A gap between the two tells you how much a company leans on inventory. The wider the gap, the more the current ratio flatters it.
- There is no universal "good" number. Above 1.0 is a common starting point, but industry and the company's own past matter more.
- Neither ratio measures cash flow, so check that before drawing a conclusion.

What the current ratio tells you
The current ratio, sometimes called the working capital ratio, checks whether a company has enough current assets to cover its short-term liabilities, according to Investopedia's explanation of the current ratio. You get it by dividing total current assets by total current liabilities, both taken from the balance sheet.
Current assets include cash, cash equivalents, marketable securities, accounts receivable, inventory and prepaid expenses, as Corporate Finance Institute's current ratio overview lists them. Current liabilities are the obligations due within the same year: accounts payable, short-term debt, accrued expenses and the like.
A result of 2.0 means the company holds $2 of current assets for every $1 it owes within the year. It is a broad measure. It says the company probably has enough resources on paper, but not how quickly those resources become cash.
What the quick ratio tells you
The quick ratio, also called the acid-test ratio, measures how well a company can pay its short-term liabilities using only its most liquid assets. Investopedia's quick ratio guide names those assets as cash, marketable securities and accounts receivable. You divide them by total current liabilities.
There are two common ways to compute it:
- Add up the quick assets: cash and equivalents + marketable securities + accounts receivable.
- Subtract what you do not trust: total current assets minus inventory and prepaid expenses.
The two methods should land on similar numbers when the balance sheet is simple. If they differ, check whether other current assets, such as deferred tax assets or assets held for sale, are sitting in the balance sheet. The first method is the cleaner one for stock analysis because you choose exactly what counts.
The quick ratio is built to show whether a company could weather a cash-flow emergency, a framing used in NetSuite's quick ratio article. That is why it matters most when a company's inventory would be slow or costly to sell.
Quick ratio vs current ratio, side by side
| Current ratio | Quick ratio | |
|---|---|---|
| Formula | Current assets ÷ current liabilities | (Cash + marketable securities + receivables) ÷ current liabilities |
| Includes inventory | Yes | No |
| Includes prepaid expenses | Yes | No |
| Strictness | Broad, more lenient | Conservative |
| Best for | A first look at overall short-term coverage | Stress-testing companies with large or slow-moving inventory |
| Always lower than the other? | Equal to or higher than the quick ratio | Equal to or lower than the current ratio |
The last row follows from the math. The quick ratio takes the same denominator but a smaller numerator, so it can never exceed the current ratio. As Investopedia's comparison of the two puts it, the quick ratio is the more conservative view because it excludes assets that are harder to liquidate.
Some sites describe the difference as a time horizon: one year for the current ratio, roughly 90 days for the quick ratio. That is a handy rule of thumb, but the accounting definition is about asset type, not a stopwatch. Focus on which assets are in the numerator.
A worked example: same current ratio, different risk
The numbers below are made up for illustration, in millions of dollars. Two companies each owe $100 million within the year.
| Balance sheet item | Company A | Company B |
|---|---|---|
| Cash and equivalents | 40 | 55 |
| Marketable securities | 10 | 5 |
| Accounts receivable | 50 | 60 |
| Inventory | 120 | 25 |
| Prepaid expenses | 10 | 5 |
| Total current assets | 230 | 150 |
| Current liabilities | 100 | 100 |
| Current ratio | 2.3 | 1.5 |
| Quick ratio | 1.0 | 1.2 |
On the current ratio alone, Company A looks clearly safer: 2.3 against 1.5. The quick ratio reverses the picture. Company A's quick assets are $100 million, exactly its short-term obligations, while Company B has $120 million of quick assets. More than half of Company A's current assets are inventory.
That does not make Company A a bad business. A retailer or manufacturer is expected to hold inventory, and a steady seller can turn it into cash on a predictable schedule. But if demand softens, that $120 million could sell at a discount or sit for months. Company B's smaller current ratio rests on assets that convert more reliably. That is the situation the quick ratio exists to catch.
What counts as a good number
The research gives a few anchors, and all of them come with conditions.
- Current ratio: a reading above 1.0 generally suggests a company has enough current assets to cover current liabilities, but what qualifies as good varies by industry and by the company's own record, per Investopedia.
- Quick ratio: a result below 1 may mean the company cannot fully pay its current liabilities in the short term using quick assets alone, while above 1 means it can (Investopedia).
- Too high is a flag too: the same current ratio article notes that a figure above roughly 3.00 could signal inefficient use of current assets or weak working-capital management. Cash piling up or inventory that is not selling both inflate the ratio.
So is a quick ratio of 0.75 good? By itself, it is below the 1.0 line, which calls for a closer look. But a grocery chain that collects cash at the register and pays suppliers on credit can run a quick ratio below 1 without trouble, because customers pay before suppliers do. A software company with large receivables and no inventory would be expected to show a higher figure. Is 1.5 a good quick ratio? Usually it signals comfortable coverage, and the question to ask next is whether the company is sitting on idle cash it could use better.
The practical rule: an acceptable current ratio varies across industries and should be judged against the company's own past ratios, as Investopedia's guide to analyzing financial position with ratios explains. Compare a company with itself over several years and with direct peers, never with the whole market.
Credit terms matter as well. BDC's current ratio guide notes that not every business fits a universal range, and that conclusions should account for the credit terms a company extends to customers and receives from suppliers. A business that gets 60 days from suppliers but collects from customers in 20 can run on thinner ratios than one with the reverse.
Which ratio should you use?
You rarely have to pick one. A simple order works well:
- Start with the current ratio for a quick read on overall coverage.
- Run the quick ratio next to see how much of that coverage depends on inventory and prepaid items.
- Look at the gap. A small gap means the balance sheet is mostly cash and receivables. A big gap means inventory does the heavy lifting.
- Match the ratio to the business. For a bank, an asset manager or a software firm, inventory barely matters, so the two ratios will sit close together. For a retailer, a homebuilder or a manufacturer, the quick ratio is the one to take seriously.
If you must choose just one for a company with meaningful inventory, choose the quick ratio. If inventory is trivial, the current ratio gives you nearly the same answer with less work.
Where both ratios fall short
Both ratios are snapshots of one balance sheet date. Neither tells you how much cash the business generates. CNBC's guide to earnings-report ratios says investors should also weigh free cash flow, liquid marketable securities, credit strength and the company's ability to roll over its debt.
A few specific traps:
- Deferred revenue. Software and subscription companies often book cash up front as a liability that is settled by delivering service, not by paying cash. The same CNBC article suggests one adjustment to the current ratio: exclude deferred revenue from current liabilities. Otherwise these companies can look weaker than they are.
- Liquidity is not cash. The current ratio measures liquidity, which differs from the actual cash position, as the Corporate Finance Institute points out. A company can post a healthy ratio and still run short of cash if receivables are slow to arrive.
- Receivables quality. The quick ratio trusts that customers will pay. If receivables are growing faster than sales, treat the ratio with suspicion.
- Window dressing. A balance sheet date can be timed. Check several quarters, not one.
For the bigger picture, pair liquidity with leverage and earnings power. Our guides to the debt to equity ratio and the interest coverage ratio cover the other two legs, and our financial health analysis guide shows how they fit together. If a company runs with negative working capital, the negative working capital rules explain when that is a business model and when it is a warning.
A short checklist for reading liquidity in a stock
- Pull current assets, current liabilities, cash, marketable securities, receivables and inventory from the latest balance sheet.
- Calculate both ratios.
- Compare them with the same company over the past four to eight quarters, looking for direction rather than a single reading.
- Compare with two or three direct competitors in the same industry.
- Check how fast inventory and receivables turn into cash.
- Confirm that operating cash flow is positive and stable.
- Look at upcoming debt maturities and whether the company can refinance them.
If the ratios are weak, cash flow is thin and debt matures soon, that is a real concern. If the ratios are modest but cash flow is strong and debt is long-dated, the picture is usually much better than the headline number suggests.
Our perspective
We built Oracle around the idea that investors get hurt less by exotic models than by skipping basics. Liquidity ratios are a good example. They are simple, they come straight from reported numbers, and they catch a surprising number of problems before a price chart does.
Our view is that a ratio should never be a verdict. It is a question. When the current ratio and quick ratio disagree, that is the interesting moment: it tells you to open the balance sheet and ask what the inventory is, how fast it sells and who owes the company money. That is the kind of discipline value investors such as Buffett, Munger and Lynch preached, and it is why we show the inputs behind every score rather than hiding them in a black box.
Our ratings are rule-based and grounded in reported company fundamentals. We do not rely on AI guesswork, so you can see why a company scored the way it did and check it yourself. If you want to see how a financial-health score fits into the whole picture, our piece on reading a value rating in under a minute is a good next step.

FAQ
What is the main difference between the quick ratio and the current ratio?
The current ratio counts all current assets, including inventory and prepaid expenses. The quick ratio counts only cash, marketable securities and receivables. Both divide by current liabilities, so the quick ratio is always the same or lower, and it is the more conservative test.
What is a good quick ratio vs current ratio?
A quick ratio of 1.0 or higher generally means a company can cover its short-term liabilities from liquid assets alone. A current ratio above 1.0 is a common minimum, with 1.5 to 2.0 often seen as comfortable. These ranges shift by industry, so compare a company with its own history and its direct peers.
Is a quick ratio of 0.75 good?
It is below 1.0, so liquid assets would not fully cover short-term obligations on their own. That is not automatically a problem for businesses that collect cash quickly and pay suppliers later, such as grocers. Check cash flow, debt maturities and the trend over several quarters before judging it.
Can a current ratio be too high?
Yes. A very high figure, for example above 3.0, can point to idle cash, unsold inventory or weak working-capital management. It is worth asking why the company holds so many current assets and whether it is earning a return on them.
Which ratio matters more for stock investors?
For companies with large inventories, such as retailers and manufacturers, the quick ratio is more revealing. For businesses with little inventory, the two ratios will be close and either works. In both cases, add cash flow and debt to the picture.
