Ratio is an expression of relationship between two or more items in mathematical terms. Exhibition of meaningful and useful relation between different accounting data is called Accounting Ratio. Ratio may be expressed as a:b (a is to b), in terms of simple fraction, integer, or percentage.
If the current assets of a concern is Rs 4,00,000 and the current liabilities is Rs 2,00,000, then the ratio of current assets to current liabilities is given as 4,00,000 / 2,00,000 = 2. This is called simple ratio. Multiply a ratio by 100 to express it in terms of percentage.
We can express the ratio between 200 and 100 in any of the following ways:
Ratios are extremely useful in drawing the financial position of a concern.
Comparative analysis and interpretation of accounting data is called Accounting Analysis. When accounting data is expressed in relation to some other data, it conveys some significant information to the users of data.

Ratio analysis is useful in many ways to different concerned parties according to their respective requirements. Ratio analysis can be used in the following ways:
It is powerful tool to measure short and longterm solvency of a company.
It is a tool to measure profitability and managerial efficiency of a company.
It is an important tool to measure operating activities of a business.

It is useful in coordinating the different functional machineries of a company.

Although Ratio Analysis is a very useful accounting tools to analyze and interpret different accounting equations, it comes with its own set of limitations:
If the data received from financial accounting is incorrect, then the information derived from ratio analysis could not be reliable.
Unauthenticated data may lead to misinterpretation of ratio analysis.
Future prediction may not be always dependable, as ratio analysis is based on the past performance.
To get a conclusive idea about the business, a series of ratios is to be calculated. A single ratio cannot serve the purpose.
It is not necessary that a ratio can give the real present situation of a business, as the result is based on historical data.
Trend analysis is done with the help of various calculated ratios that can be distorted due to the changes in the price level.
Ratio analysis is effective only where same accounting principles and policies are adopted by other concerns too, otherwise intercompany comparison will not exhibit a real picture at all.
Through ratio analysis, special events cannot be identified. For example, maturity of debentures cannot be identified with ratio analysis.
For effective ratio analysis, practical experience and knowledge about particular industry is essential. Otherwise, it may prove worthless.
Ratio analysis is a useful tool only in the hands of an expert.
Ratios can be classified on the basis of financial statements or on the basis of functional aspects.
Ratios calculated from taking various data from the balance sheet are called balance sheet ratio. For example, current ratio, liquid ratio, capital gearing ratio, debt equity ratio, and proprietary ratio, etc.
Ratios calculated on the basis of data appearing in the trading account or the profit and loss account are called revenue statement ratios. For example, operating ratio, net profit ratio, gross profit ratio, stock turnover ratio.
When the data from both balance sheet and revenue statements are used, it is called mixed or composite ratio. For example, working capital turnover ratio, inventory turnover ratio, accounts payable turnover ratio, fixed assets turnover ratio, return of net worth ratio, return on investment ratio.

Similarly, turnover ratios are calculated to know the efficiency of liquid resources of the firm, Accounts Receivable (Debtors) Turnover Ratio and Accounts Payable (Creditors).
Debt equity ratio and interest coverage ratio are calculated to know the efficiency of a firm to pay longterm debts and to meet interest costs. Leverage ratios are calculated to know the proportion of debt and equity in the financing of a firm.
Activity ratios are also called turnover ratios. Activity ratios measure the efficiency with which the resources of a firm are employed.
The results of business operations can be calculated through profitability ratios. These ratios can also be used to know the overall performance and effectiveness of a firm. Two types of profitability ratios are calculated in relation to sales and investments.
