Ratio Analysis

Ratio analysis is a business practice in which mathematical formulas are used to summarize and study relationships among different aspects of a company’s financial position based on the figures provided in the company’s financial statements. Ratio analysis uses ratios, i.e., one number divided by another number, to evaluate aspects of a company’s financial health, including its liquidity, profitability, and solvency. Ratio analysis may be applied for several different purposes, including to compare the financial position of several companies, to track changes in one company over time, or to compare the performance of a company against that of its industry or the economy as a whole.

Overview

Many different types of ratios are used in ratio analysis. All ratios are the product of dividing one number by another, and the ratios used in financial ratio analysis have been selected because they are believed to reveal something important about a company’s financial condition or health.

Liquidity ratios measure a company’s ability to access cash quickly. The working capital or current ratio is determined by dividing a company’s current assets by its current liabilities. The current ratio is an indication of a company’s ability to pay current liabilities using current assets. The quick ratio, also called the acid test ratio, is calculated by dividing a company’s quick assets (cash, accounts receivable, notes receivable, and short-term securities) by current liabilities.

Profitability ratios quantify a company’s ability to generate income and cash flow. The profit margin ratio is determined by dividing net income by net sales, and is generally used to compare a company to an industry average. The asset turnover ratio divides net sales by average total assets, and measures the efficiency of a company; comparisons using the asset turnover ratio are best done within an industry, as expectations about the asset turnover ratio often vary by industry. The return on assets ratio divides net income by average total assets, and is considered a measure of overall profitability.

Solvency ratios are used to estimate a company’s health over the long term. The total debt to total assets ratio is computed by dividing total debt (total liabilities) by total assets. The times interest earned ratio is calculated by dividing EBIT (earnings before interest and taxes) by interest expense, and is an indication of a company’s ability to meet its interest obligations.

The techniques of ratio analysis are commonly used in financial analysis because they take information readily available from financial statements and present it as a set of individual numbers that are easily comprehended. Ratio analysis also facilitates comparisons among companies of different sizes, or in making comparisons of one company’s position over time. However, the information provided through ratio analysis it is only as good as the quality of numbers reported in the financial statement, and also only as current as the financial statement used. Ratio analysis may be misleading when comparing companies in different industries, which operate under different conditions, or companies from countries that use different accounting standards and practices.
