What is Quick Ratio (Acid Test)?
Definition
The quick ratio, also known as the acid-test ratio, measures a company's ability to meet short-term obligations using only its most liquid assets. It excludes inventory from current assets, providing a more conservative view of liquidity than the current ratio.
Detailed Explanation
The quick ratio is calculated by subtracting inventory and prepaid expenses from current assets, then dividing by current liabilities. The numerator typically includes cash, cash equivalents, short-term investments, and accounts receivable — assets that can be converted to cash relatively quickly.
By excluding inventory, the quick ratio addresses a key weakness of the current ratio: inventory may not be easily or quickly convertible to cash, especially during economic downturns. A retailer with warehouses full of unsold merchandise may have a strong current ratio but a weak quick ratio, revealing true liquidity risk.
A quick ratio of 1.0 or higher is generally considered adequate, meaning the company can cover all current liabilities without selling any inventory. Companies with quick ratios consistently below 0.5x may face liquidity challenges if business conditions deteriorate.
The quick ratio is particularly important for industries with perishable, seasonal, or obsolescence-prone inventory. Technology companies with rapidly depreciating components, fashion retailers, and food companies should be evaluated with the quick ratio rather than the current ratio.
Formula
Quick Ratio = (Current Assets - Inventory - Prepaid Expenses) / Current LiabilitiesExample
A company with $800M in current assets, $250M in inventory, $50M in prepaids, and $400M in current liabilities has a quick ratio of ($800M - $250M - $50M) / $400M = 1.25x.

Working capital is the difference between a company's current assets and current liabilities. It measures a company's short-term liquidity and operational efficiency, indicating whether it has enough resources to cover its near-term obligations.
Current Ratio
The current ratio measures a company's ability to pay short-term obligations by dividing current assets by current liabilities. A ratio above 1.0 indicates the company has more short-term assets than liabilities, suggesting adequate liquidity.
Inventory Turnover
Inventory turnover measures how many times a company sells and replaces its inventory during a period. A higher turnover indicates efficient inventory management and strong demand, while low turnover may signal overstocking or weak sales.
