Steam - External Funds Used

Read a news article today which mentioned a function I haven't known so far. Maybe it is actually new or I am just not very informed. Anyway, they talked about the Steam account data for "External Funds Used". As far as I understand, this refers to every cent supplied externally and ignores all purchases made with money you got by selling cards and items.

Out of curiousity, I checked my value (right now I am not 100 % sure if "Old spend" is included in the total spend but I think so):

Total Spend: 1994.83 USD
Old Spend: 357.02 USD

Under the assumption that old spend is included, it would mean I spent around 2000 $ on Steam. A good third (675 €) are from the Steam Deck. Would still be around 1300 $ for games (or market). Considering I am 13 years on Steam, it means roughly 100 $ per year. Which is higher than I expected. However, checking my history - which also is new to me - this also includes Steamgifts I bought for SG. So, it is lower. To lazy to make the math. Would be nice if Steam would already separate it into years, so I could check how it changed over time. Technically, I could do it myself. But still to lazy.

If you are curious, you can check your "pure" Steam spendings without "internally circulated" money and without bundle additions, here:

EDIT: Did the math and about 317.5 € are for gifting stuff. Would leave 913 $ spend in 13 years, resulting in 70 $ spend per year. Which is cheaper than streaming.
