Most available research shows that the shoot rates for female is right at a grand with the star female performers making 2k per shoot. So doing the math If she shoots 200 days  of the year they are bring in 100k to 200k respectively per year. By the way that is a shit ton of days a year to be shooting.  

With that said I could see someone like Reagan Foxx for instance making another 100k annually off OnlyFans as she is very active with her fans. My guess is Reagan Foxx/Kendra Lust level stars knock back around 350k. Although I am pretty sure the agent get's 10 percent. But this stuff about pornstars pulling in 50-100k monthly seems incredibly far fetched and closer to mythology that reality.  

The outlier to consider is what some of these pornstars are making on UTR introductions to celebrities and athletes and alike. I will throw in 20k-50k a year for these intro high profile client hook ups. I know for a fact this scenario happens first hand.

I meant to say I guarantee she does not more than 3k per shoot even with her raise in profile. Spitballin here but I would guess she shoots 100  days a year, so she is knocking back 200k-250k on filming. However, she probably makes another 100k on Onlyfans as she is very active with her fans. Throw in50k for some VIP/Celebrity/Athletes private introduction hookups which happens all the time with top pornstars and Ms. Foxx could be pulling in 400k. These gals make a tremendous living, but thee is shelf life that factors in for the older stars. Read an article that said, the average to above average girls make around 90k-100k. The male performers by contrast to not get even half of those shoot opportunities and they can make as low as 400k per.
