Quick Ratio (Acid-Test)

The quick ratio measures a company's ability to meet short-term liabilities with its most liquid assets, excluding inventory from current assets.

Calculated as current assets minus inventory, divided by current liabilities, the quick ratio is a stricter liquidity test than the current ratio because inventory can be hard to convert to cash quickly. A ratio of one or above generally indicates comfortable short-term liquidity.

The quick ratio is especially relevant for businesses where inventory is slow-moving or perishable. Comparing it with the current ratio shows how dependent a company's apparent liquidity is on selling stock, which matters when assessing its ability to weather a cash crunch.
