Quick Ratio: Formula and What It Means
The quick ratio measures whether a company can cover its short-term liabilities with its most liquid assets. Here is the quick ratio formula, a worked example, what a good quick ratio looks like, and how it differs from the current ratio.
Can a company pay what it owes in the next few months without having to sell inventory or borrow? The quick ratio answers exactly that. Also called the acid-test ratio, it is one of the most-watched measures of short-term liquidity, because it strips out the assets that are hardest to turn into cash quickly and asks a simple question: if the bills came due now, could you cover them?
This guide explains what the quick ratio is, the formula, a worked example, what a good number looks like, and how it compares to the current ratio.
What is the quick ratio?
The quick ratio (or acid-test ratio) measures a company's ability to cover its current liabilities with its most liquid assets, the ones that can be converted to cash quickly. It deliberately excludes inventory, because inventory can be slow or uncertain to sell. A higher quick ratio means stronger short-term liquidity.
The quick ratio is the acid test of liquidity: forget the inventory you might sell and the favors you might call in, can you cover what you owe right now with cash and near-cash? That is why lenders and investors lean on it.
The quick ratio formula
Quick Ratio = (Current Assets − Inventory) / Current Liabilities
An equivalent version adds up only the liquid assets directly: (Cash and equivalents + Marketable securities + Accounts receivable) / Current liabilities. For example, with $500,000 in current assets, $200,000 of that in inventory, and $250,000 in current liabilities:
- Quick Ratio = ($500,000 − $200,000) / $250,000
- Quick Ratio = $300,000 / $250,000 = 1.2
A quick ratio of 1.2 means the company has $1.20 of liquid assets for every $1.00 of short-term liabilities.
What is a good quick ratio?
As a rule of thumb, a quick ratio of 1.0 or higher is considered healthy: it means the company can cover its current liabilities without selling inventory. Below 1.0 can signal liquidity pressure, though it varies by industry, some businesses run lean on purpose. Much above 1.0 is safe but can suggest cash is sitting idle rather than being put to work. As always, the trend over time and the comparison to industry peers matter more than the absolute number.
Quick ratio vs. current ratio
| Quick ratio | Current ratio | |
|---|---|---|
| Formula | (Current assets − inventory) / current liabilities | Current assets / current liabilities |
| Includes inventory? | No | Yes |
| What it measures | Immediate liquidity | Broader short-term liquidity |
| Stricter? | Yes, more conservative | No, more lenient |
The current ratio includes inventory and other current assets, so it is more lenient. The quick ratio is the stricter test, which is why it is the one people reach for when they want a conservative read on liquidity.
Why the quick ratio matters
- Liquidity check. It shows whether a company can meet near-term obligations without fire-selling assets or borrowing.
- Lender and investor signal. Creditors and investors use it to gauge short-term financial health and risk.
- Early warning. A falling quick ratio can flag tightening liquidity before it becomes a crisis.

Frequently asked questions
What is the quick ratio?
The quick ratio, or acid-test ratio, measures whether a company can cover its current liabilities with its most liquid assets, excluding inventory. A ratio of 1.0 or higher generally indicates healthy short-term liquidity.
How do you calculate the quick ratio?
Quick Ratio = (Current Assets − Inventory) / Current Liabilities. For example, $500,000 in current assets minus $200,000 of inventory, divided by $250,000 of current liabilities, gives a quick ratio of 1.2.
What is a good quick ratio?
Generally 1.0 or higher, meaning the company can cover current liabilities without selling inventory. It varies by industry, and the trend over time and peer comparison matter more than the absolute figure.
What is the difference between the quick ratio and the current ratio?
The quick ratio excludes inventory and measures immediate liquidity; the current ratio includes inventory and measures broader short-term liquidity. The quick ratio is the stricter, more conservative test.
The bottom line
The quick ratio is the acid test of short-term liquidity: liquid assets minus inventory, divided by current liabilities. A reading of 1.0 or higher generally means a company can meet its near-term obligations without selling inventory or borrowing. Read it alongside the current ratio, the trend, and industry peers for the full picture.
