Company Research: Industry Surveys, Ratios, NAICS/SIC

Industry Ratios

The purpose of calculating industry ratios is to evaluate your chosen company's strengths and weaknesses as compared to those of competing businesses in that industry.

There are several government websites available for searching the NAICS codes:
