Financial Ratios: A Complete Guide for Investors

Investing in stocks or other financial instruments can be daunting for many people, especially those new to the market.

One of the most critical aspects of investment analysis is the ability to assess a company’s financial health and performance. This is where financial ratios come into play.

Financial ratios provide investors with essential information about a company’s financial position, profitability, liquidity, and efficiency.

This complete guide will delve into financial ratios and explore everything an investor needs to know to make informed investment decisions. 

What are Financial Ratios?

Financial ratios provide a numerical representation of a company’s financial state by comparing different figures in its financial statements.

A change from one figure to another can indicate a change in the company’s financial situation. Various ratios can be used to assess a company’s growth, sales, profits, efficiency, and leverage.

By analyzing a company’s financial ratios over time and comparing them with industry benchmarks, investors and analysts can evaluate its growth and development.

Also, monitoring financial ratios over time can help investors adjust their investment strategies accordingly.

Categories of Financial Ratios

Financial ratios are classified into several groups, including,

1. Solvency ratios

Solvency ratios measure a company’s long-term financial stability by measuring its ability to meet its long-term obligations.


By analyzing these ratios, investors and creditors can evaluate whether a company can repay its debts, such as loans and bonds, when they come due.


Debt-to-equity ratio, interest coverage ratio, and debt service coverage ratio

2. Liquidity ratios

Liquidity ratios measure a company’s short-term liquidity or ability to pay off its creditors and other short-term obligations on time.


These ratios indicate whether a company can meet its short-term financial obligations, such as payroll and bills.


Current ratio, quick ratio, and cash ratio

3. Payout ratios

Payout ratios measure the proportion of earnings a company pays out as dividends to shareholders.


A high payout ratio indicates that a company pays a significant portion of its earnings as dividends. In contrast, a low payout ratio indicates that a company is retaining earnings for reinvestment in the business.


Dividend payout ratio and dividend yield

4. Profitability ratios

Profitability ratios measure how much profit a company generates in relation to the sales, assets, or equity capital it employs.


These ratios help investors evaluate a company’s ability to profit from its operations.


Gross profit margin, net profit margin, and return on assets

5. Coverage ratios

Coverage ratios measure how often a business can cover its current liabilities with assets like cash, receivables, and inventory.


By analyzing these ratios, investors can determine whether a company has enough liquid assets to meet its short-term financial obligations.


Interest coverage ratio

6. Market prospect ratios

Market prospect ratios provide information that helps investors project a company’s earnings and expected performance.


Investors use these ratios to evaluate a company’s growth potential, expected earnings, and potential return on investment.


Price-to-earnings ratio, earnings per share, and price-to-book ratio

Significance of Financial Ratios in Investment Analysis

1. Industry Benchmarking

Financial ratios can be compared to those of other companies within the same industry to evaluate a company’s financial performance.

But, it is crucial to consider that some industries have higher ratios than others.

2. Growth Tracking

Monitoring a business’s growth and development can also be done by tracking financial ratios over time.

For instance, to determine if a company has increased its earnings from the previous year, you can calculate financial ratios like the working capital ratio and compare it to the previous year’s figures. This comparison will reveal if the business has grown or declined.

3. Profitability Tracking

Profitability ratios, such as the profit margin ratio, reveal a company’s profits and the cost incurred to generate that profit.

Notable Examples of Financial Ratios

Below are the notable ratios used for financial analysis,

1. Working Capital Ratio

The working capital ratio, also known as the current ratio, is a financial ratio that measures a company’s ability to pay off its short-term liabilities using its short-term assets.

The formula for calculating the working capital ratio is as follows:

Working Capital Ratio = Current Assets / Current Liabilities

For example, if a company has current assets of $200,000 and current liabilities of $100,000, the working capital ratio would be $200,000 / $100,000 = 2:1.

This means the company has $2 in current assets for every $1 in current liabilities. Generally, a working capital ratio of 2:1 or higher is considered good. In contrast, a ratio of less than 1:1 may indicate liquidity issues.

The working capital ratio is essential for creditors, investors, and management because it provides a snapshot of a company’s liquidity position. It helps to determine whether the company can pay its short-term liabilities and how efficiently it uses its working capital.

2. Acid-test or Quick Ratio

The quick ratio, also known as the acid-test ratio, is a liquidity ratio that measures a company’s ability to pay its short-term financial obligations by using only its most liquid assets. This includes cash, cash equivalents, and accounts receivable that can be converted into cash quickly.

The formula for the quick ratio is:

Quick Ratio = (Current Assets – Inventory – Prepaid Expenses) / Current Liabilities

For example, if a company has current assets of $100,000, inventory worth $20,000, prepaid expenses of $5,000, and current liabilities of $50,000, the quick ratio would be ($100,000 – $20,000 – $5,000) / $50,000 = 1.5

This means the company has $1.50 of liquid assets to pay off every dollar of its current liabilities.

A quick ratio of 1 or higher indicates that a company has enough liquid assets to cover its short-term obligations. But, the ideal quick ratio can vary by industry, and a company’s unique circumstances may affect an acceptable level of liquidity.

3. Earnings per share ratio

Earnings per share (EPS) is a financial ratio measuring the portion of a company’s profit allocated to each outstanding share of its common stock. EPS is a widely used metric in financial analysis, as it helps investors assess a company’s profitability per share.

The formula for calculating EPS is:

EPS = Net Income / Average Number of Common Shares Outstanding

For example, suppose a company has a net income of $1,000,000 and $ 500,000 common shares outstanding. Its EPS would be $1,000,000 / 500,000 = $2

This means that for each outstanding share of the company’s stock, the company earned $2 of profit.

A higher EPS generally indicates greater profitability, but analyzing other financial metrics and qualitative factors is important before making investment decisions.

4. Price-to-Earnings ratio

The price-to-earnings ratio (P/E ratio) is a financial metric used to evaluate the value of a company’s stock relative to its earnings. It shows how much investors will pay for each dollar of earnings.

The P/E ratio is calculated by dividing the market price per share by the company’s earnings per share (EPS). The EPS is typically calculated as the company’s net income divided by the total outstanding shares.

The formula for the P/E ratio is:

P/E Ratio = Market Price per Share / Earnings per Share

For example, if a company trades at $50 per share and its EPS is $2, the P/E ratio would be $50 / $2 = 25.

This means investors are willing to pay $25 for every dollar of earnings.

A high P/E ratio may indicate that investors expect strong future earnings growth. In contrast, a low P/E ratio may indicate that the company is undervalued or that investors are pessimistic about its future growth prospects.

5. Gross margin ratio

The gross margin ratio is a profitability ratio that measures the percentage of sales that exceed the cost of goods sold.

The formula for calculating the gross margin ratio is:

Gross margin ratio = (Revenue – Cost of Goods Sold) / Revenue

For example, suppose a company has a revenue of $500,000 and a cost of goods sold of $300,000. The gross margin ratio would be ($500,000 – $300,000) / $500,000 = 0.4 or 40%

This means that for every dollar of sales, the company has 40 cents left to cover its other expenses, such as salaries, rent, and marketing.

A high gross margin ratio implies that the company has a competitive advantage in its market and can generate strong profits. Conversely, a low gross margin ratio suggests that the company may struggle to compete with its rivals and could face financial difficulties in the long term.

6. Asset turnover ratio

The asset turnover ratio is a financial ratio that measures the efficiency of a company in using its assets to generate revenue. It measures how much revenue is generated for every dollar of assets owned by the company.

The formula for the asset turnover ratio is:

Asset turnover ratio = Revenue / Average Total Assets

For example, if a company generates $2 million in revenue and has an average total asset balance of $5 million, then its asset turnover ratio would be $2 million / $5 million = 0.4

This means that for every $1 of assets owned by the company, it generates $0.40 in revenue.

A higher asset turnover ratio indicates that a company generates more revenue per dollar of assets, which is generally seen as a positive sign. However, a very high ratio may indicate that a company is not investing enough in its assets and may be operating with lower quality or insufficient assets.

Financial Ratios for Cryptocurrencies

From an investment perspective, some of the commonly used financial ratios for cryptocurrencies are,

1. Market Capitalization

This is the total market value of a cryptocurrency and is calculated by multiplying its current price by its total circulating supply.

2. Volume

This measures the amount of cryptocurrency being traded in the market. High trading volumes can indicate a high level of interest in a cryptocurrency.

3. Liquidity

This measures the ease of buying or selling a cryptocurrency in the market. High liquidity can indicate a more active market, making it easier for investors to buy and sell.

4. Price-to-Earnings (P/E) ratio

This ratio is used to evaluate a cryptocurrency’s earnings potential by comparing its price to its earnings. However, since cryptocurrencies do not have earnings in the traditional sense, this ratio is not widely used for them.


Financial ratios are vital for investors to assess a company’s financial health and performance.

As we have seen in this guide, various financial ratios provide investors with valuable insights into a company’s profitability, liquidity, efficiency, and solvency.

By understanding financial ratios, investors can make informed investment decisions, minimize risks, and maximize returns. But, it’s essential to remember that financial ratios are not the only factor to consider when investing.

It’s essential to conduct thorough research, analyze market trends, and understand the company’s industry to make well-informed investment decisions.


1. What are financial ratios used for?

Financial ratios are used to evaluate a company’s financial performance and position. They provide valuable insights into a company’s profitability, liquidity, solvency, and efficiency.

By comparing a company’s ratios with those of other companies in the same industry or over time, investors and analysts can assess a company’s strengths, weaknesses, and overall financial health.

Financial ratios are also useful for identifying potential risks and opportunities, determining the company’s valuation, and making informed investment decisions.

2. What are the limitations of financial ratios?

Several limitations of financial ratios should be considered.

  • Financial ratios may not provide a complete picture of a company’s financial position, as they are based on historical financial data and may not reflect its current situation.
  • These ratios can be affected by industry differences, accounting methods, and other external factors.
  • Financial ratios cannot capture qualitative factors such as the company’s management team, innovation, and brand reputation.
  • The interpretation of ratios requires careful analysis. A single ratio may not provide a clear conclusion without considering other ratios and factors.
