[MCU]How much did Tony Stark spend on all Iron Man suits?

I read somewhere that he spends 1.5 billion on regular suits and 7 billion on each nano tech suits. There were 49 regular suits and 36 nano tech suits if I’m not wrong. That means he spent 325.5 billion dollars on all his suits up until Endgame, where he wore the Mark 85 suit. There’s no fucking way this man spent over 300 billion on suits lol. He also spent a lot of money on the Avengers facilities and shit like that so that would mean he probably spent like half a trillion on everything. Does anybody have any idea how much he actually spent?

There's a difference between what his suits theoretically cost and how much he spent on them.

The thing of it is that he did all the R&D work himself, he already owned all the tooling, or built that himself from tooling he already owned, and built the things himself.  What he spent was essentially the cost of raw materials, which is probably in the hundreds of thousands to low millions of dollars.

So while it would cost hundreds of billions to buy them, (if he was selling), he actually spent very little.  Realistically, he probably spent more on the vault he keeps them in than on the suits themselves, since he would've contracted that out.
