Current Ratio:
It is a measure of general liquidity and is most widely used to make the analysis for short term financial position or liquidity of a firm. It is calculated by dividing the total of the current assets by total of the current liabilities.
Current Ratio = Current Assets / Current Liabilities

Acid-Test Ratio:

Receivables Turnover Ratio:
An accounting measure used to quantify a firm's effectiveness in extending credit as well as collecting debts. The receivables turnover ratio is an activity ratio, measuring how efficiently a firm uses its assets.

Inventory Turnover Ratio:
Stock turn over ratio and inventory turn over ratio are the same. This ratio is a relationship between the cost of goods sold during a particular period of time and the cost of average inventory during a particular period. It is expressed in number of times. Stock turn over ratio/Inventory turn over ratio indicates the number of time the stock has been turned over during the period and evaluates the efficiency with which a firm is able to manage its inventory. This ratio indicates whether investment in stock is within proper limit or not.
The ratio is calculated by dividing the cost of goods sold by the amount of average stock at cost. Inventory Turnover Ratio = Cost of goods sold / Average inventory at cost |

'Profit Margin':
A ratio of profitability calculated as net income divided by revenues, or net profits divided by sales. It measures how much out of every dollar of sales a company actually keeps in earnings.

Profit margin is displayed as a percentage; a 20\% profit margin, for example, means the company has a net income of $0.20 for each dollar of sales.

Asset Turnover:
The amount of sales generated for every dollar's worth of assets. It is calculated by dividing sales in dollars by assets in dollars.
