So, no concrete numbers, but most estimates I could find still kept shit at under $25,000/minute. There is not a string of words I could flow together to adequately express how fucking incompetent RT are to have animated something that looks this "Okay" at this budget level.
It's largely a "normal" thing in the space. Creatives often make for dogshit business people.
The people that started RoosterTeeth were not business people and never felt a need to re-examine any numbers. Monty Oum (who probably had cheaper costs) never actually ran a show before as a commercial product and would have next to no understanding of how it actually works and this info never was picked up by Miles or Kerry. The fact they likely let key people (Miles, Kerry, Barbara, who knows who else) double/triple dip into the money on top of VA drama almost certainly adds up as well.
For RWBY Volume 2 (at least) - it was let out that Monty was taking in at least $250,000/year as a salary. There are C-Level employees at small/midsize companies not taking that as salary. That's before anything else he was getting from RWBY's backend (merch sales, a cut of subs). It is a fucking insane amount of money to pay someone with an unproven product - plus whatever they were paying Miles and Kerry (but not Sheena, lol).
EDIT - Apparently the salary amount was undisclosed and the $250,000 was from the GoFundMe that Sheena helped herself to. RT gave Sheena (allegedly) a year of Monty's salary upon his death but I crossed up the amounts.
You can see it clearly written in how much they try to monetize RWBY (games, movies, RT First, CrunchyRoll Plus or whatever) that the only thought they had in their head was "(Money from Show) needs to be bigger then (Money Spent on Show)" and not once did they successfully examine the idea of making the core business more efficient.
RoosterTeeth died as a business because they never actually tied to be one - they just accidentally were one for a few years when Content Money was pretty big.
You see this in most Youtube Channels that are "big" - they do dumb shit like rent office space, hire friends as editors, expand into ill-advised ventures, and so on. Game Grumps is most notorious for this (with Arin having like 30 alleged employees for a Let's Play channel lazily cut into 10m segments).
