The costs associated with buying a franchise are as varied as the franchise opportunities themselves. For example, you wouldn't expect to pay the same for a yogurt shop as you would for McDonalds or even for an upscale restaurant. Buying a franchise can cost as little as a few thousand dollars to a few hundred thousand dollars.

The franchise fee is going to be based on projected revenue which is largely based on past revenue. Therefore, if you buy a franchise that takes in hundreds of thousands of dollars in a certain amount of time, that franchise is going to cost you more than one that would take in $10,000 in the same period of time.

You can buy a mobile franchise with a relatively low start-up cost that you run by yourself or even a storefront franchise that essentially has a front counter. It all depends on the nature and revenue of the business.

When you buy a franchise, you also have to pay royalties to the franchiser. This can range from about 3 to 8 percent of the total revenue of your business. If you have opted for a brick and mortar franchise, you'll have leasing costs, employees to pay, and most likely, a relatively expensive electric bill every month.

Buying a franchise can be an exciting and profitable way to start a new business. The key is to do your homework and find out all the facts before you plunk down your life savings. Learn about all the costs involved with buying a franchise; don't stop investigating once you find out what the franchise fee is.
