Gamers on Reddit recalled a hidden page on Steam where you can see your total expenses over time.
It’s done in just a few clicks: Help → Steam Support → My Account → Data associated with your Steam account → External Funds Used. The ‘TotalSpend’ field will display the total amount in dollars—even if you paid in rubles.
Some users discovered that they had spent tens of thousands of dollars on their game libraries. On average, users’ spending ranges from a few hundred to several thousand dollars. They also recalled common discount traps: “The game only cost $1, but in the end, it added up to multiple mortgages.”

So if you’re ready to discover the truth—check your account. You might be in for an unpleasant surprise.
