The Quick Ratio (Acid-Test Ratio): The Liquidity Number Lenders Trust More Than Your Current Ratio
The quick ratio (acid-test ratio) measures whether a business can cover current liabilities using only cash, marketable securities, and receivables — deliberately excluding inventory and prepaid expenses. Covers the formula with a worked example, why loan covenants often set a quick-ratio minimum instead of a current-ratio one, why 1.0 is the textbook benchmark but fast-turn retailers healthily run 0.3–0.4, and the mistakes that make the ratio misleading.
