SteamDB gives you a valuation based on full price. The article describes an entry on Steam's Help page that gives you an accurate number of how much money you paid to Valve, including micro-transactions.

That's very unlikely, I couldn't have spent so much money on steam. I've bought like 5 games on steam and not even at full price. The rest comes from grey zone shops/HB

Edit: Just added up the numbers in my purchase history, it's about 1/4 of the sum there

Maybe it also counts transactions from the Steam Market? I also found my TotalSpend hard to believe, but it's also not like I've traded hundreds of dollars worth of items in the market.

The description of the support page notes that these values are used to determine some sort of limited user account status. It might not be intended to keep an accurate tally. I wouldn't be surprised if these values are only available due to gdpr and accuracy of the description was not a priority when they set it up. I'm implying that the employee who wrote the description might not have understood the value precisely enough.

But who knows. I could just be huffing copium about my game expenses 😅

I've maybe sold an item or two for a few cents, nothing more
