Liquidity ratios tell you about a company's ability to meet its financial obligations, including debt, payroll, vendor payments, and so on.
- Current Ratio. This is a prime measure of how solvent a company is. It's so popular with lenders that it's sometimes called the bankers ratio. Generally speaking, the higher the ratio, the better financial condition a company is in. A company that has $3.2 million in current assets and $1.2 million in current liabilities would have a current ratio of 2.7 to 1. That company would be generally healthier than one with a current ratio of 2.2 to 1. To calculate the current ratio, divide total current assets by total current liabilities.
- Quick Ratio. This ratio isn't faster to compute than any other--it simply measures the ratio of a company's assets that can be quickly liquidated and used to pay debts. Thus, it ignores inventory, which can be hard to liquidate (and if you do have to liquidate inventory quickly, you typically get less for it than you would otherwise). This ratio is sometimes called the acid-test ratio because it measures a company's ability to deal instantly with its liabilities. To calculate the quick ratio, divide current assets minus inventory by current liabilities.
- Interest coverage. This measures a company's margin of safety: how many times over the company can make its interest payments. To calculate interest coverage, divide income before interest and taxes by interest expense.
- Debt to Equity. This measure provides a description of how well the company is making use of borrowed money to enhance the return on owner's equity. To calculate the debt-to-equity ratio, divide total liabilities by owners' equity.
