Here’s how Entrepreneur (from its website) came up with its list:

The process began in July 2015, when we asked franchisors to participate in our survey. Each submission was vetted before being entered for data analysis; 951 companies made the first cut. Of those, the top 500 became the Franchise 500® ranking, based on financial and statistical data from July 2013 through July 2015.

Only franchise companies that supply a full Franchise Disclosure Document (FDD) or Canadian Disclosure Document and whose information is verified by Entrepreneur can receive a listing. To be eligible for the Franchise 500®, a franchisor must have a minimum of 10 units, with at least one franchise located in the U.S. The company must be seeking new franchisees in the U.S., and it cannot be in Chapter 11 at the time the ranking is compiled. (The exception to these rules is Canada-based companies that are expanding only in Canada.)

All companies are judged by the same criteria: objective, quantifiable measures of a franchise operation. The most important factors include financial strength and stability, growth rate and size of the system. We also consider the number of years a company has been in business and the length of time it’s been franchising, startup costs, litigation, percentage of terminations and whether the company provides financing. An independent CPA analyzed the financial data, according to Entrepreneur.
