What business ratios should you know and be using? Here’s a breakdown of common ratios, how they’re used, and in some cases how you’ll calculate them.

Main ratios

• Current. Measures company’s ability to meet financial obligations. Expressed as the number of times current assets exceed current liabilities. A high ratio indicates that a company can pay its creditors. A number less than one indicates potential cash flow problems.
• Quick. This ratio is very similar to the Acid Test (see below), and measures a company’s ability to meet its current obligations using its most liquid assets. It shows Total Current Assets excluding Inventory divided by Total Current Liabilities.
• Total Debt to Total Assets. Percentage of Total Assets financed with debt.
• Pre-Tax Return on Net Worth. Indicates shareholders’ earnings before taxes for each dollar invested. This ratio is not applicable if the subject company’s net worth for the period being analyzed has a negative value.
• Pre-Tax Return on Assets. Indicates profit as a percentage of Total Assets before taxes. Measures a company’s ability to manage and allocate resources.

• Net Profit Margin. This ratio is calculated by dividing Sales into the Net Profit, expressed as a percentage.
• Return on Equity. This ratio is calculated by dividing Net Profit by Net Worth, expressed as a percentage.

Activity ratios

• Accounts Receivable Turnover. This ratio is calculated by dividing Sales on Credit by Accounts Receivable. This is a measure of how well your business collects its debts.
• Collection Days. This ratio is calculated by multiplying Accounts Receivable by 360, which is then divided by annual Sales on Credit. Generally, 30 days is exceptionally good, 60 days is bothersome, and 90 days or more is a real problem.
• Inventory Turnover. This ratio is calculated by dividing the Cost of Sales by the average Inventory balance.
• Accounts Payable Turnover. This ratio is a measure of how quickly the business pays its bills. It divides the total new Accounts Payable for the year by the average Accounts Payable balance.

In the real world, financial profile information involves some compromise. Very few organizations fit any one profile exactly. Variations, such as doing several types of business under one roof, are quite common. If you cannot find a classification that fits your business exactly, use the closest one and explain in your text how and why your business is different from the standard. ### See why 1.2 million entrepreneurs have written their business plans with LivePlan
