TBH, I never kept a serious count of my VPSes. They are usually left to own devices except from time to time when I upgrade the minimal OS and 2-3 applications. I get reminders about payments and pay, otherwise. If I do a really hard count now I go over 10 that I pay, 2 in US and the rest in EU.
There is also the BlueVM one which is suspended for doing traffic of 1.4 tb instead of .5 allowed last month in the first few days and I dont know if it will come back today or not to check what could have went so terribly wrong without getting blacklisted or something. So, would be 11 with that.
In EU I have DO, EDIS, torq, and a few in NL and UK. I also colo a server in Voxility.
With home connection of 1 gbps best effort i push-pull some 40 TB a month, mostly tor relays (restricted exits from home) freenet and gre/IPv6 experiements which encapsulate the above mentioned traffic over weird routes.
I pay some 75 Eur a month for all this.
