Current Ratio & Quick Ratio
Overview
Liquidity ratios measure a company's ability to meet short-term obligations, and they are often the earliest warning signal of financial distress. The current ratio and quick ratio are the two most important liquidity measures for fundamental analysts evaluating stocks across every sector. This guide explains how to calculate, interpret, and benchmark both ratios — skills that underpin sound value investing decisions. Explore definitions of these and other financial ratios in our glossary, and use the stock screener to filter for companies with healthy liquidity profiles.
Key Takeaways
- Current Ratio = Current Assets / Current Liabilities — above 1.5 is generally safe.
- Quick Ratio (Acid-Test) = (Cash + Receivables + Short-Term Investments) / Current Liabilities.
- The quick ratio excludes inventory, making it a stricter measure of liquidity.
- Very high current ratios (above 3) may indicate inefficient use of assets.
Practical Tips
- Compare liquidity ratios within the same industry for meaningful benchmarks.
- A declining current ratio quarter-over-quarter signals growing short-term stress.
- Pair liquidity ratios with the cash conversion cycle for a complete working-capital picture.

Return on Equity (ROE)
