Sometimes called the acid test, the quick ratio is an indicator of a company's ability to meet its short-term liabilities. It is the total of a company's cash plus accounts receivable plus short-term investments divided by its current liabilities. The higher the number the healthier the position and within an industry, high quick ratios suggest relatively high liquidity. The quick ratio is similar to the current ratio, which is a less stringent test because it adds inventory (which may not always be easy to sell quickly) to cash, accounts receivable and short-term investments before dividing by current liabilities.
