There is a lot more to the read but this part helps best describe how you rank up or down.



Factors affecting Elo Points
There are two and ONLY two factors that can affect a player's Elo Points (either gain or loss):

The first and foremost is Round Win/Loss:

You and other players on your Team will always lose points if a round is Lost. How much point each player loses depends on how much points they had in the beginning. A player with more points would lose more than a player with less points in case a round is lost.

You and other players on your Team will always gain points if a round is Won. How much point each player gains depends on how much points they had in the beginning. A player with more points would gain less than a player with less points in case a round is Won.

Bottomline: It is impossible to gain Elo Points on Round Loss and lose Elo Points on Round Win.

The second important factor is MVP:

The player who scores an MVP is rewarded a significantly larger share of Elo Points than the other four players (which COULD HAVE but didn't score the MVP). However if the player with most points gains a MVP he will always get less points than a player who does not have the most points. Please do not confuse this sentence, he will still get a lot more points than the other four players that didn't get the MVP.

Bottomline: The player with most MVP will most likely gain more Elo Points than others.

Anything listed bElow does NOT have ANY effect on Ranks & Points unless it leads to a MVP:
  • Kills, Assists & Deaths
  • Teamkills or Suicides
  • Headshots
  • Accuracy
  • Grenades kills, knife kills, stylish kills or anything of this sort
  • The time each rounds takes (to win or lose)
  • Losing/Winning with or without the bomb planeted
  • Soreboard position and/or Score
  • Achievements gained during each round (if any)
  • Hostage rescues or shots
  • Damage given and/or Taken
  • etc. (Anything else you can imagine)

So what affects your rank (points gained or lost) in a nutshell is:
  • Current Elo Points (rank)
  • Round Win/Loss
  • MVPs Gained

It could be cool if Valve could make like a table where you could see when you rank up or down.
