IDK, don't think it's far off. Just from there patreon income alone they'll be pulling over 500k/y (this just by calculating there base fee $5 per vid, they have 2,062 patreons, so assuming some will be paying more, they'll likely be getting more than 500k/y just from patreon) ex taxes, fees etc.
Nevermind the income they get from merch, sponsors and YT ads.
Not trying to be negative, I say good on them, they worked hard on it, and have been doing it for years.
