>>107380383Tough to say in Mint's case. She really doesn't get sponsorships, though her merch sells insanely well to the point of being an extreme outlier.
I think a more clear number would be Doki, who said her concert took around an entire month's worth of income to fund. (50k, so 600k annual at the time). Doki regularly drops merch collabs and takes sponsors almost every week, though I'm still not sure if 50k in this case is revenue or income after paying all of her employees and work commissions. If it IS after payments, then just by virtue of Mint having less expenses she could've easily saved up a massive nest egg due to not having those giant costs.
And I'd expect the Holos clearly have made more money over a longer period of time than her just from passive merch cuts, so they're probably quite well off.
Though iirc Kanata grew up VERY poor, which often leads to reckless spending once given effectively a blank check, so I could see her completely misusing her funds if not managed properly, but I want to hope that isn't the case.
