League of Legends: MMR aka Match Making Rating

MMR MEANING / DEFENITION

In this article we will explain what is MMR and how it works. As mentioned in the title MMR is an abbreviation what means Match Making Rating. Shortly, MMR is a hidden rating everyone has which determines players you meet in solo queue and the amount of league points you gain or lose. If you gain about 17-20 league points per win, your MMR is usual for your current division. 

MMR AND ELO ALGORITHMS

MMR is using same values as ELO system which has been in use before invention of division / league system. However exactly MMR determines players you meet in solo queue and LP gain or lose while league system shows your tier and progress publicly.

HOW MMR IS CALCULATED IN LEAGUE OF LEGENDS

Everytime you win or lose, your MMR changes accordingly. Amount of MMR gain / lose depends on average MMR of players you faced in ranked game.

MMR RANKING AND JUMPING OVER DIVISIONS

During a long win streak, MMR starts to outrun your current division / ELO. In this case you would receive up to 40 points per win while lose only about 10-15. Such MMR allows to jump over division, e.g. Gold 5 to Gold 3. However it’s compensated the fact that you wouldl be matched against opponents 2-5 divisions above yours. This often happens during big elo boosting orders, when 7 or more divisions should be elo pushed up.

HOW ELO DECAY AFFECTS MMR

Also you can experience such huge LP gain after decay. If you haven’t played League of Legends for a long time and several divisions were decayed then you would gain really huge amount of the LP per win. This would happen because your MMR haven’t changed while your division / ELO position actually did.

MMR DROP

If you experience hard lose streak then the hell happens. Amount of league points you gain is about 8-12 while you can lose up to 30. Those orders are hardest to complete for elo boosters. If you got such league points gain please be patient, it would take longer than orders with average or high MMR.

MMR BOOSTING WHEN MMR IS LOW

If your MMR is really low and you gain just a few league points per win (9-12) then you may need a helping hand because a win streak is needed to get out of such situation. You can check options we provide here. If you want to boost it by yourself then finding a realiable duo partner would be a good idea.

MMR AND DODGE DURING CHAMPION SELECTION

Dodging a game during champion selection doesn’t affect your MMR but you will lose few league points or will get lose if you are in series.

DUO QUEUE AND MMR

When you are playing in duoq you will be matched according average value of your MMR and your duo partner plus 30 to compensate duoq advantage. For example. If you have 1400 MMR (Silver 2) and you mate has 1650 MMR (Gold 4) you will be matched against players with (1400+1650)/2+30 = 1540 MMR (Gold 5).

MMR IN NORMAL GAMES, TWISTED TREELINE, TEAM RANKED, ARAM AND DOMINION

There is separated MMR for each game mode thus your performance in ranked games doesn’t affect other game modes, including normal games.

MMR RESET AT THE BEGINNING OF NEW SEASON

At beginning of the new season your MMR will get soft reset. This means that all players won’t start from the same position and your performance in previous season is important. 

MMR AND PLACEMENT MATCHES

Provisional matches may be a chance to boost your MMR signiticantly because they affect it most. 

MMR AND PICK ORDER IN SOLO QUEUE

Originally, MMR played a role in the distribution of positions during champion selection, e.g. the person who have highest MMR was first pick. This feature was removed to avoid any flame situations about first and last picks and now seeding in solo queue is random.

*You can check your aproximate MMR if you visit op.gg and make a search of your summoner name and then click “Calculate my MMR” button. This data is not official but shown MMR would be very close to real value (they calculate average position of players you recently met in solo queue and show it as your MMR).

    Oh this clears things up. Thanks a lot!
    So, for at least half an year I’m not playing lol with my 855 MMR in bronze 2

  2. Lurvepöse

    I’ve been playing League of a long while, I ended in diamond 2 when I stopped playing like 8 months ago.

    Then when I came back for season 5, I played my placement matches and I ended in plat 5… now I’ve been playing for lik 2 months tops and I’ve had 80% win rate pretty much. When I got promoted to diamond 5 after I had a win streak, I literally won 10 games to get to my promotion, I lost the first match in the series but I managed to win the following two so I got promoted to diamond 4.

    First game I played in diamond 4 I won aswell, but I still only got 11lp.

    According to Op.gg my MMR is 2137 when the “average” in the league is 2424. Despite me winning so so many games.

    Any1 know why?

  3. Julia

    Is your KDA more important than the number of victories? I hope it is, because nowadays we are always losing the matches but thank god my KDA is not that bad.

  4. Spoon

    Multiply the number op.gg give you by 1.166 and then compare it to the list of divisions/tiers above for a more accurate idea of where you stand.

    1. Turtlerino timerino

      i doubt it, if that was true my mmr would be gold 1… i’m in gold 5 atm.
      the mmr cant be that much higher, can it?

      1. Boosteria

        You actually can. Then you will gain 30+ LP and will jump over division. Also it can happen if you decayed and your MMR stayed the same. You can have Diamond MMR even on gold if your position affected by decay.

      2. Oskos

        I have played once against gold player while i was diamond. His MMR was a diamond one, he just had hard decay. I checked all his games were against dia elo players + it wans’t due to duo for sure. So MMR can be very different from your league position, but most time they are really close to each other.

  5. Polar

    my MMR says that its like 234 MMR. how can i raise it to be higher. im bronze 5 but lately ive been going into bronze 4. then getting promos and going on losing streak back to bronze 5 due to my low MMR

  6. kefko

    how is it posible that being in plat V and having 1535 mmr (according to euw.op.gg) i win like 20 average lp per game? this makes no sense at all… can anyone explain this to me? plat v is supposed to be 1900 mmr according to this post…

    1. StarClay666

      I have no idea either but I got pretty much the same problem. Last game I lost 300 MMR and I won the game and my stats was 25/2 as a midlaner and got good farm too. Something is wrong i tell you that.

  7. Fork

    Feels kinda bad to be stuck in bronce II and know that I have a silver V mmr, I’m winning like 25 average lp but still can’t get out, and I’m not here to complain, but people there are seriously tough to carry. Anyone can give me some advice?

    1. Kinga

      Play champions who can carry hard. Get good with strong champs and as long as you are good, it wont really matter how bad your teammates are. Also, the other team isn’t very good either since its bronze. As long as you win lane and take control of the lane by roaming to get your teammates ahead, then you will most likely win. Don’t be risky, throws suck. :P

  8. Knights17

    im in bronze 3 and my mmr is 1159 and it says my the mmr is average for where im at although after looking at the mmr distribution arent i ment to be in s5 or b1

  9. wtf is my mmr

    im in bronze 3 and my mmr is 1159 and it says my the mmr is average for where im at although after looking at the mmr distribution arent i ment to be in s5 or b1

  10. Luke and Sona

    Well, it shouldn’t happen when you are getting 8 LP and losing 30 because you were on downstreak. That just stops you from playing rankeds…

  11. Struggles life

    got into bronze 4 (ew bronze .-.) and just started getting 13 lp for every win then 20 something for a loss even when I win multiple games in a row y rito
