Math-time.
Let's assume that each digital copy is sold at around $60 - we'll have some copies that are sold cheaper on key-sites, regional-tricks etc., and some that are more expensive through pre-order bonuses, +pass etc. That comes to 1,666,666 copies sold digitally.
That sounds pretty close to what we've heard so far; Anthem is Biowares best selling launch-title after Mass Effect 3, which doubled Mass Effect 2s launch sales on consoles, and sold around 1,2 million copies on consoles excluding PC:

So in terms of how succesful the game is based solely on ROI at the moment we have to look at the games budget. We have to guess, both because budgets are fairly different depending on what type of game we're talking about, and because of Anthems long development. Anthem is fairly sized open-world shlooter, and probably a massive marketing budget. Let's assume it's something close to Grand Theft Auto V's budget of $250 million (

Even taking into account, that these are US-numbers only, I would guess that Anthem still haven't reached it's break-even-point. Given that Destiny sold 6.3 million copies in it's first month, and accrued over $500 million dollars in day one sales (
https://gamerant.com/destiny-sales-numbers-210/) I would assume that the negative reviews hurt the game significantly, and that EA aren't happy with the numbers.
DISCLAIMER: This is something I found on the internet, and put together in 15 minutes. Someone with more time, can probably do a much more thorough and precise job.
