Level calculator

A level calculator, on ROBLOX, is a calculator that allows a user to input some statistics about himself and that then gives the user a level depending on the values he gave. Many users calculate their level with a level calculator and then put that level on their profile.

Currently, the most known level calculator is clockwork's, on his ROBLOX HQ website. However, there are also others, though most are based the same formula, miked's BC formula.

The BC formula contest
In June 2007, the staff invited users to suggest formulas to calculate the worth of a user. They would then choose one of the formula to award BC to a certain group of users, to test a new feature.

The winner was miked. His formula calculated the level by taking various inputs, giving a certain importance to each, and returning a level from 1 to 99.

miked's BC formula is: $$\frac{-60}{\frac{1.2p}{5000}+1}+80+\frac{-12}{\frac{f}{100}+1}+\frac{-8}{\frac{r}{10}+1}+8\left(\left(\frac{-1}{\frac{k}{70}+1}+1\right)-\left(\frac{-1}{\frac{w}{1400}+1}+1\right)\right)$$ where:

  p is the number of place visits  m is the number of months played  f is the number of friends  k is the number of knockouts  w is the number of wipeouts  r is the number of ROBUX 

Clockwork's calculator
Clockwork's level calculator is currently the most known level calculator. It is based on miked's BC formula. It asks you to give it your number of place visits, months played, profile views, friends, KOs, wipeouts and forum posts.

ROBLOXRanks
ROBLOXRanks was a popular website created in 2012 that caught the attention of many users. The website scanned anything you posted on the forums, in comments, etc. and ranked you based on that. The owner has since quit and shut down the website.
