Depends on what plan you do. I believe it's cheaper if you have more people on the same plan. But by yourself, no more than $40.00
I'm not sure if you can pay for just a month. They have three plans for contract. The shorter the contract the higher the monthly charge I did 18 month's for me and my daughter and I pay about 72 a month. After the first 30 days you can go to any anytime fitness.
