Cash Ratio

What Does Cash Ratio Mean?
The ratio of a company's total cash and cash equivalents to its current liabilities. The cash ratio is most commonly used as a measure of company liquidity. It can therefore determine if, and how quickly, the company can repay its short-term debt. A strong cash ratio is useful to creditors when deciding how much debt, if any, they would be willing to extend to the asking party.

Investopedia explains Cash Ratio
The cash ratio is generally a more conservative look at a company's ability to cover its liabilities than many other liquidity ratios. This is due to the fact that inventory and accounts receivable are left out of the equation. Since these two accounts are a large part of many companies, this ratio should not be used in determining company value, but simply as one factor in determining liquidity.
