What is a normal monthly cost to join a boxing gym?

I know I'm 17 and I've never boxed before, but I've always had an interest in boxing since I was little. Unfortunately I never had the money and neither did my parents. Now I'm VERY interested and I just want to know if it's expensive or not to join a boxing gym.|||about 40 to 80 bucks but you rarely see a all boxing gym any more there more towards mma but some gyms have boxing teams and some boxing gyms or mma gyms have a non profit license to where you train for free show your grades are up to par,depends on there criteria and train 4 to 5 times a week and compete.you could also try ymca"s and boys and girls clubs.|||$ 200.00 a oth at least.
