A professional consultant company can use this document to calculate various financial ratios. This document provides a template balance sheet and income (profit and loss) statement whereby users should input the proper values. The spreadsheet then calculates profitability ratios (gross margin, profit margin, return on assets, return on investment, and return on equity), liquidity ratios (working capital, current ratio, and quick ratio), and debt ratios (debt ratio and long-term debt to equity ratio). Financial ratios are used to perform quantitative analysis; they show the statistical relationships between pieces of financial data. Such ratios can be used to evaluate past, current, and projected performance of a company, or they can be used to compare two different companies.
