While the initial fee to franchise a Taco Bell is $45,000, the company won’t approve you as an owner unless you have at least $750,000 in liquid cash available. You also have to have a minimum net worth of $1.5 million or more, according to Eater. Overall, you can expect to spend upwards of $1.2 million to start a Taco Bell, although the average yearly sales will usually top $1.4. million.
