My FIL is a pastor of a mega church satellite church and he makes in the 6 figures. I don't know how much exactly but he has a nice house, a german luxury coupe and a german luxury SUV and buys suits from neiman marcus. I'd guess more than $100K but probably less than 200k. The pastor of the main location is no doubt a millionaire tho, has a jet etc.
Considering the amount of work my FIL does every week....I say $80-100K is fair for a large church. He works 50+ hours a week easy. Funerals, bible studies, sunday service, marriage counseling, outreach, and admin stuff he does for the mega church. it's not unusual for him to be working until like 11pm
