Have you ever wondered how much money you've invested into your entire Steam collection? Well, now you can! Valve has recently added a nifty feature called 'External Funds Used' that allows Steam users to see the total amount of money spent at the Steam store. All users have to do is sign into their Steam account at this link. Do note that the tool doesn't take into account key activations. So, games that have been purchased through third-party stores like GOG, Green Man Gaming, Humble Bundle, G2A, and etc. will not contribute to the grand total. The "OldSpend" field equals to the amount of money that was spent before the Limited User Account policy was implemented in 2015. The "PWSpend" is related to purchases made on games operated by Perfect World Entertainment. a Chinese company that runs CS:GO and DOTA 2 in China. So, how much have you spent? Let us know in the comments below.
