Understanding these four types of financial ratios helps you assess different aspects of a company’s health. Liquidity gauges the ability to meet short-term obligations with readily available assets, and a common example is the current ratio, which compares current assets to current liabilities. Solvency looks at long-term financial stability and debt capacity, with debt-to-equity as a typical measure of how much debt is used relative to owners’ equity. Profitability evaluates how effectively a company turns revenue into profit, and the net profit margin is a standard example that shows how much of each revenue dollar becomes net income. Efficiency examines how well assets are used to generate sales, and asset turnover is a classic example that relates sales to total assets. The pairing described above matches the way these concepts are usually defined and measured, using current ratio for liquidity, debt-to-equity for solvency, net profit margin for profitability, and asset turnover for efficiency. Other options mix up these concepts or rely on metrics that don’t align with the standard definitions (for example, using ROI or cash flow for liquidity, or claiming all four concepts are the same).
