Quick Ratio (Acid-Test)
Quick Ratio = (Current Assets - Inventory) / Current Liabilities
The quick ratio is a more stringent liquidity measure than the current ratio. It excludes inventory because inventory may not be quickly convertible to cash. Also known as the acid-test ratio, it shows ability to meet short-term obligations with the most liquid assets.

Quick Ratio = (Current Assets - Inventory) / Current Liabilities
Variables
Total current assets including cash, receivables, and inventory
Goods held for sale or materials for production
Obligations due within one year
Example Calculation
Scenario
Company ABC has current assets of $200,000, inventory of $80,000, and current liabilities of $100,000.
Given Data
Calculation
Quick Ratio = ($200,000 - $80,000) / $100,000
Result
1.2
Interpretation
The company can cover its current liabilities 1.2 times with its most liquid assets. A ratio above 1.0 suggests good short-term liquidity even without selling inventory.
When to Use This Formula
- ✓When inventory is slow-moving or hard to liquidate
- ✓For more conservative liquidity analysis
- ✓When comparing companies with different inventory levels
- ✓Assessing true emergency liquidity
Common Mistakes
- ✗Using quick ratio alone without considering industry norms
- ✗Forgetting to exclude prepaid expenses in some formulations
- ✗Not analyzing receivables quality (some may be uncollectible)
FAQs
Common questions about this formula
Inventory is excluded because it's typically the least liquid current asset. It must be sold (often at a discount in distress) and collected before becoming cash. In a crisis, inventory may not provide immediate funds.
The current ratio includes all current assets, while the quick ratio excludes inventory. The quick ratio is more conservative and useful when inventory is slow-moving or when you need to assess true emergency liquidity.
Yes, in the strictest formulation. Prepaid expenses can't be converted to cash — they're consumed, not collected. The most conservative quick ratio formula is: (Cash + Short-Term Investments + Accounts Receivable) / Current Liabilities. Some textbooks use Current Assets minus Inventory, which still includes prepaids — check your context.
A quick ratio below 1.0 means the company cannot cover its current liabilities with its most liquid assets alone. It would need to sell inventory or obtain additional financing to meet short-term obligations. This isn't necessarily a crisis — retailers routinely operate below 1.0 because their inventory turns over quickly — but it warrants closer analysis.
