Total
allocation is around 115 billion USD so far. If you (for some inexplicable reason) divide that by population you get around 300 USD-ish, since 2022. Maybe a teensy bit more if you count from 2014.
But that's
allocation. I'm not an expert in these matters, but I would still assume that "allocated" is in no way whatsover the same as actually paid out. For all you know what the war has actually cost the U.S could be a fraction of the 115 billion, and a lot of it is in the form of outdated military materiel that would only have been sent to the scrap heap otherwise, or at best donated as hand-me-downs to some other nation.
As for the funds actually paid out,
a lot of that goes back into western economies in the form of arms deals et cetera.
In short, there is a reason you're not feeling any economic effects of this war in any way.
