 What are Financial Ratios?

Financial ratios are mathematical calculations that use data from a company’s financial statements to provide insights into its financial health, performance, and efficiency. These ratios help investors, analysts, and stakeholders evaluate a company’s profitability, liquidity, solvency, and operational efficiency.

Key Categories of Financial Ratios

• Profitability Ratios: Measure a company’s ability to generate profit relative to revenue, assets, or equity.
• Liquidity Ratios: Assess a company’s ability to meet short-term obligations.
• Solvency Ratios: Evaluate a company’s long-term financial stability and ability to meet long-term obligations.
• Efficiency Ratios: Indicate how well a company utilizes its assets and manages its operations.
• Valuation Ratios: Reflect the market’s perception of the company’s value relative to its earnings, sales, or book value.

Important Financial Ratios to Monitor

 1. Profitability Ratios

• Gross Profit Margin

The gross profit margin measures the percentage of revenue that exceeds the cost of goods sold (COGS). It indicates how efficiently a company produces its goods or services.

Gross Profit Margin = {(Revenue – COGS) / Revenue} X 100

• Net Profit Margin

The net profit margin measures the percentage of revenue that remains as profit after all expenses, including taxes and interest, have been deducted. It reflects a company’s overall profitability.

Net Profit Margin = {Net Income/ Revenue} X 100

 2. Liquidity Ratios

 Current Ratio

The current ratio measures a company’s ability to meet its short-term obligations with its short-term assets. A ratio above 1 indicates that the company has more current assets than current liabilities.

Current Ratio = Current Assets / Current Liabilities

 Quick Ratio

The quick ratio, also known as the acid-test ratio, measures a company’s ability to meet its short-term obligations with its most liquid assets (excluding inventory).

Quick Ratio = {Current Assets -Inventory} / Current Liabilities

 3. Solvency Ratios

 Debt-to-Equity Ratio

The debt-to-equity ratio measures the relative proportion of a company’s debt to its shareholders’ equity. It indicates the level of financial leverage and risk.

 Interest Coverage Ratio

The interest coverage ratio measures a company’s ability to pay interest on its debt with its earnings before interest and taxes (EBIT). A higher ratio indicates better debt-servicing capability.

Interest Coverage Ratio = EBIT / Interest Expense

The inventory turnover ratio measures how efficiently a company manages its inventory by comparing the cost of goods sold to the average inventory. A higher ratio indicates efficient inventory management.

Inventory Turnover Ratio} = COGS /  Average Inventory

 Asset Turnover Ratio

The asset turnover ratio measures how efficiently a company uses its assets to generate revenue. A higher ratio indicates better utilization of assets.

Asset Turnover Ratio = Revenue / Average Total Assets

 Price-to-Earnings (P/E) Ratio

The P/E ratio measures a company’s current share price relative to its earnings per share (EPS). It indicates how much investors are willing to pay for each dollar of earnings.

P/E Ratio = Share Price /EPS

 Price-to-Book (P/B) Ratio

The P/B ratio measures a company’s current share price relative to its book value per share. It indicates whether a stock is undervalued or overvalued.

P/B Ratio = Share Price / Book Value per Share
