If you didn't know, Overwatch is getting an anniversary event to celebrate its first birthday, with new content aplenty included, and some bright sparks over on Reddit have done some research into how many credits you'll need to buy all this content and spoilers: it's a lot.
Firstly, user Desks_up calculated that 56,475 credits would be needed for the 108 items in the event, with 33,000 going towards the 11 legendary skins, and the 25 sprays costing the least, at 1,874. They then compare this figure to those of previous events, as Uprising needed 36,825 credits for 95 items, being the second most expensive behind the anniversary.
Another user, JollyGirl, also did their own calculations and, assuming you spent all available credits by the end of Uprising, between then and the end of Anniversary, you'd need to collect 1,380 credits per day in that 41-day period, which is again higher than other events.
As pointed out by other Reddit users, though, random drops decrease this cost significantly, but these stats still make for interesting reading. Do you plan on getting all the content, or just some of it?
