How mutch child suport should a father pay a month?

Huh? Child support is a percantage based on how much a month the parent thats giving it makes. If you dont want to go through the courts then its up to you to decide, there is no set limit, its a deal between you and the other parent if they agree. It cost more than 150 a month on average to pay for the support of a child. I was owed that much as a child back in like 1983. Things have gone up, 150 isnt much, but its up to you. Really its best to go through the courts so that no one on either side gets screwed, and if your the person paying out then keep record of what you give, because by not going through the courts can later bite you in the rear without record. good luck~
