apple developer fee

if i have a free app, in which i sell clothes, or services, or collect monthly payments. how much is the fee that i will have to pay?

i understand that apple charges 30% on paid apps. but how does it work with free apps with in-app purchases?

or what if i am selling a service or a product does apple take a percentage of that? or just the $99/fee yearly?
