Key ratios are fundamental mathematical relationships used to evaluate and summarize the financial condition and performance of a company. These ratios help stakeholders—such as investors, analysts, and management—make informed decisions by providing insights into various aspects of financial health, such as liquidity, profitability, efficiency, and solvency.
These key ratios fall into several categories:
- Liquidity Ratios: Measure a company’s ability to meet its short-term obligations.
- Profitability Ratios: Assess a company’s ability to generate profit.
- Efficiency Ratios: Evaluate how effectively a company utilizes its assets.
- Solvency Ratios: Determine a company’s long-term financial stability.
Types of Key Ratios with Examples
Liquidity Ratios
-
$$ \text{Current Ratio} = \frac{\text{Current Assets}}{\text{Current Liabilities}} $$Example: A current ratio of 2 means the company has twice as many current assets as current liabilities, indicating good short-term financial health.
-
Quick Ratio (Acid-Test Ratio):
$$ \text{Quick Ratio} = \frac{\text{Current Assets} - \text{Inventory}}{\text{Current Liabilities}} $$Example: A quick ratio of 1.5 suggests that, excluding inventory, the company has 1.5 times more liquid assets than its current liabilities.
Profitability Ratios
-
$$ \text{Net Profit Margin} = \frac{\text{Net Income}}{\text{Revenue}} \times 100 $$Example: A net profit margin of 10% implies that the company earns a net income of $0.10 for every dollar of revenue.
-
$$ \text{ROE} = \frac{\text{Net Income}}{\text{Shareholder's Equity}} \times 100 $$Example: An ROE of 15% means the company generates $0.15 in profit for every dollar of shareholders’ equity.
Efficiency Ratios
-
$$ \text{Inventory Turnover} = \frac{\text{Cost of Goods Sold}}{\text{Average Inventory}} $$Example: An inventory turnover ratio of 5 indicates the company sells and replaces its inventory five times a year.
-
$$ \text{Asset Turnover Ratio} = \frac{\text{Revenue}}{\text{Total Assets}} $$Example: An asset turnover ratio of 2 suggests the company generates $2 of revenue for every $1 of assets.
Solvency Ratios
-
$$ \text{Debt to Equity Ratio} = \frac{\text{Total Liabilities}}{\text{Shareholder's Equity}} $$Example: A debt to equity ratio of 0.5 means the company has $0.50 of debt for every dollar of equity.
-
$$ \text{Interest Coverage Ratio} = \frac{\text{EBIT}}{\text{Interest Expense}} $$Example: An interest coverage ratio of 3 indicates that the company earns three times its interest expense, suggesting it is well-positioned to cover interest obligations.
