A level calculator on ROBLOX is a calculator that allows a user to input some statistics about themselves and that then gives the user a level depending on the values they gave. A user can calculate their level with a level calculator and then put that level on their profile. Currently, the most known level calculator is clockwork's calculator, which is located on his ROBLOX HQ website. However, there are also others, though most are based the same formula: miked's BC formula.
