To find out how much money has been spent on League of Legends (LoL), the best way is to use the official Riot Games "Show Me the Money" tool available on their support website. By logging in with the Riot account, this tool automatically calculates the total amount spent in the current region of the account. If the account has been changed between regions, Riot support can be contacted for a detailed summary. This method provides an accurate total of money spent on Riot Points, skins, champions, event passes, and other in-game purchases. Players have reported a wide range of spending: many have spent under $1000, but some have spent several thousand dollars over years of playing. If the tool is down for maintenance, submitting a support ticket to Riot Games' customer support can also provide this information. In summary, the exact amount spent can be found by:

• Going to Riot Games' official support page for "How Much Money Have I Spent in LoL?"
• Logging into the relevant Riot account
• Clicking the "Show Me the Money" button on the page

This provides a clear and official total spend figure for the player.
