Understanding Financial Ratios

Financial ratios are important tools used in evaluating a company’s financial health and performance. Common financial ratios come from a company’s balance sheet, income statement, and cash flow statement. These ratios provide insights into various aspects of the business, such as its profitability ratios, liquidity, leverage ratios, and efficiency.

Several key financial ratios include earnings per share (EPS), price/earnings ratio (P/E), return on equity (ROE), debt-to-capital ratio, and interest coverage ratio (ICR).

Understanding Financial Ratios

Earnings per share (EPS)

EPS stands for Earnings Per Share. It tells us how much profit a company has made for each share of stock. We use this number to see if the company is making money. If the EPS goes up, it means the firm is doing well and earning more profit.

This makes investors happy because when a company earns more, its shares become worth more too.

Earnings per share (EPS)

Price/earnings ratio (P/E)

The price/earnings ratio (P/E) is a key number in stock analysis. It shows how much investors pay for each dollar of company earnings. A high P/E means a stock may be costly compared to its earnings.

On the other hand, a low P/E might mean the stock is cheap.

To figure out the P/E ratio, we divide the share price by earnings per share (EPS). We can use two types of EPS: trailing and forward. Trailing EPS uses past data, while forward EPS uses future projections.

For example, Warren Buffett looks for firms with low P/E ratios that hold strong growth hope ahead.

Return on equity (ROE)

ROE shows how good a business is at making money from owner funds. It divides net income by shareholder equity. It tells you the profit for each dollar of equity. ROE can change based on industry type, so it’s best to compare it with similar businesses.

High ROE often pulls in more companies and can lead to normal profits again. Investors look at this ratio when they pick stocks so they know their investment could bring solid returns.

Debt-to-capital ratio

The debt-to-capital ratio tells us how a company pays for its growth. This ratio shows the amount of money a company borrows compared to what it owns. To find this ratio, you divide total debt by total debt plus shareholders’ equity.

A high ratio, like over 40 percent, may mean that the company has too much debt. Yet, some steady companies can handle more debt without harm. It is a helpful tool to check if a company uses loans or earnings for expansion.

Interest coverage ratio (ICR)

The Interest Coverage Ratio (ICR) tells us how well a company can pay its debt. We find it by splitting the earnings before interest and taxes (EBIT) by the cost of interest payments. If the ICR is high, that means the firm has an easy time covering its debts.

But if it’s low, this might mean trouble ahead for paying back money owed. This number is critical for businesses with lots of debt to keep track of.

The Importance of Financial Ratios in Stock Analysis

Financial ratios play a crucial role in stock analysis as they provide key insights into a company’s financial statements, helping investors make informed investment decisions.

Enterprise value to EBIT

The Enterprise value to EBIT ratio is a tool for checking a company’s earnings. This ratio includes debt. It lets us see and compare how much money different companies make from their operations.

Warren Buffett, a well-known investor, uses this for picking businesses with good growth and low P/E ratios. Companies with high debt might be risky. If the Debt-to-capital ratio is more than 40 percent, we need to watch it closely.

The Interest coverage ratio can tell us if a company can pay off its debts in all types of economic states.

Operating margin

Operating margin is a key tool for checking how much profit a company makes from its main work. To find it, you divide the operating profit by all the money that comes in. It can show investors just what’s under the hood of a firm’s business.

The people at the top can play with numbers that affect net income and earnings per share, but they have less wiggle room when it comes to operating margin. This ratio gives us real facts without any tricks or twists.

Quick ratio

The quick ratio, also known as the acid test ratio or cash ratio, is an important financial liquidity ratio that helps determine if a company can pay its short-term debt payments using liquid assets that can quickly be turned into cash.

This quick ratio is especially useful for analyzing companies facing financial difficulties or during economic downturns. To calculate the quick ratio, subtract inventory from current liquid assets and then divide it by current liabilities.

A higher quick ratio indicates that a company has a better ability to meet its short-term obligations.

Price/earnings-to-growth, or PEG, ratio

The Price/earnings-to-growth, or PEG, ratio is an important financial ratio used in stock analysis. It helps investors determine if a stock is overvalued or undervalued based on its growth potential.

The PEG ratio combines the price/earnings (P/E) ratio and the company’s projected earnings growth rate. A PEG ratio of 1 indicates that a stock is fairly valued. If the PEG ratio is below 1, it suggests that a stock may be undervalued, while a PEG ratio above 1 suggests that a stock may be overvalued.

Investors consider the PEG ratio as a more reliable measure of a stock’s value compared to just the P/E ratio alone.

Price-to-sales, or P/S, ratio

The P/S ratio compares a company’s stock price to its annual sales per share. It helps investors understand the valuation of a company relative to its revenue. The calculation involves dividing the market price per share by the sales per share.

Generally, a lower P/S ratio indicates that a stock may be undervalued, while a higher P/S ratio suggests potential overvaluation.

Price-to-book, or P/B, ratio

The Price-to-Book (P/B) ratio compares a company’s stock price to its net asset value or book value. It helps determine if a stock is trading at a premium or discount to its book value.

A low P/B ratio may indicate an undervalued stock and a potential buying opportunity, while a high P/B ratio suggests an overvalued stock with limited potential returns. This ratio is particularly useful for analyzing capital-intensive companies.

Debt-to-equity, or D/E, ratio

The D/E ratio is an important financial ratio that measures a company’s debt in relation to its equity. It is calculated by dividing the total debt of the company by its total equity.

A higher D/E ratio suggests that a company relies more on debt for funding, while a lower D/E ratio indicates a higher proportion of equity in the company’s capital structure. This ratio is used to assess a company’s financial health and its capacity to handle debt obligations.

Role of the financial ratio in decision-making

Financial ratios play a crucial role in decision-making for investors and businesses. These ratios provide valuable insights into a company’s financial health and performance. By analyzing different ratios like earnings per share, price/earnings ratio, return on equity, debt-to-capital ratio, and interest coverage ratio, investors can assess the profitability, liquidity, solvency, and overall stability of a company.

This information helps them make informed decisions about whether to invest in a stock or not. Similarly, businesses can use these ratios to evaluate their own financial situation and make strategic decisions regarding growth opportunities or managing long-term debt effectively.

Financial ratios are an essential tool that guides decision-making for individuals and organizations alike when it comes to investing or running a successful business.

The key is to consider multiple ratios in combination to get a comprehensive understanding of a company’s financial situation before making investment decisions.


The most important financial ratios depend on the specific aspect of a company’s performance you are evaluating, such as profitability, liquidity, or solvency.

To determine the most important financial ratio for your business, consider your industry norms and objectives. For example, if growth is a priority, you may focus on ratios related to revenue and net profit margin.

Some commonly used company financial ratios include gross profit margin (gross profit divided by sales), current ratio or working capital ratio (current assets divided by current liabilities), and debt-to-equity ratio (total debt divided by shareholders’ equity).

Financial ratios provide valuable insights into a company’s profitability, efficiency, risk management, and overall health. They help investors and creditors assess its ability to generate profits and meet its obligations.
