The average cost of jiu-jitsu classes is $50 to $200 per month, depending on the class age range, number of classes per week, your commitment or contract length, and the instructor's expertise and reputation. Jiu-jitsu gyms and academies are more expensive if they have well-known instructors who are national champions on staff.
In addition to the monthly class or gym fee, you'll have extra costs for gis and belts. A jiu-jitsu gi costs $60 to $120 on average, while belts cost $15 to $30. Some gyms also charge a fee for belt promotion. However, this is frowned upon by reputable academies and is often considered a warning sign of a low-quality gym.
