How much does a 7.5/10 mm earn per month?

Was talking online with a friend about how much mm makes per month (who used to be in the industry.) Wanted to know how much you guys think a mm who works 24 days a month can earn? I've heard crazy figures from a few different people with a pretty wide spread.  I told one mm what another mm told me and they said that's too much and impossible. Any bros have any intel on this topic?
