While most of us can go our entire League of Legends career without worrying about MMR, others may take the game more seriously.

If you enjoy competitive games, you have probably tried to find your matchmaking rank or MMR but have come up empty. That’s because the MMR value is secret.

While there’s no official way of knowing your exact MMR value in the LoL matchmaking system, there are ways to get a rough estimate, which is what this article is all about.

If you are ready to get a general idea of your own MMR, keep reading below to see everything you need about how League of Legends MMR works!

What is MMR?

In gaming, including League of Legends, MMR stands for Match Making Rank and is the multiplayer system games use to match you with other players around your skill level.

In that sense, the LoL MMR relates to ranking systems that describe a player’s skill level, such as the ELO rating. ELO was used in LoL in the first couple of years but later changed to MMR.

The ELO system is best known in chess but is now implemented in anything from sports to esports. An example of the latter could be Brawlhalla.

While you can see your MMR in most games, League of Legends uses a hidden number system, making it a bit more difficult to figure out what yours is. 

While League of Legends does not make it easy, and no one is fully sure how exactly the MMR system works, there are two ways to estimate your MMR.

I will explain both methods below; you can use whichever one you feel most comfortable with.

League of Legends Ranks:

  1. Iron (beginner)
  2. Bronze
  3. Silver
  4. Gold
  5. Platinum
  6. Diamond
  7. Master
  8. Grandmaster
  9. Challenger (best)

Using an MMR Checker

An online MMR checker is the first option to get a general idea of your MMR.

There are quite a few third-party websites available, and they give you an estimated range for your MMR instead of an exact number.

Thus, you may get differing scores from different MMR checkers and not your actual MMR score.

However, a general estimate of your position in the LoL ranking system can help you determine whether you are being matched against opponents who are either too high or too low-leveled.

Calculating Your MMR Manually

If you’re a math geek, you can also calculate your match making rating yourself. Calculating your MMR is more difficult, but hey, you want to know how you stand in a ranked game, right!?

I mean, we can’t, with a good conscience, call ourselves hardcore competitive League of Legends players if we don’t even know how to pinpoint a player’s rank in the LoL matchmaking rating system.

If you still wish to calculate it manually, follow the steps below to get rough estimates of your MMR for solo and party ranking.

  1. Locate your Solo and Party Ranking in League of Legends.
  2. Once you have found those numbers, plug them into the equation (1000* Solo Ranking) + (300 * Party Ranking).
  3. The number you come up with is your rough MMR.

However, this method is less accurate than an online League of Legends MMR checker.

While no method gives you an accurate MMR, you will receive a more likely score from third-party MMR checkers.

Additional Methods For Figuring Out Your Rough MMR Rank

Now that you know how to check your MMR in League of Legends, it is important to understand what other additional methods can help give you an idea of your MMR.

While these methods will not give you an estimated MMR, they will help you know if you are likely to be promoted, demoted, or stay in your current Rank. 

MMR Effects on League Point Gain

You gain or lose League Points (LP) based on your MMR when you play Ranked games in League of Legends.

How much LP you gain from each match depends on how well you play.

This is then compared to your current rank to determine whether you should move up, down, or stay where you are in the ranked system.

To move up a division in your current Rank, you need 100 LP, and depending on the number of LP gains you receive after a game can help you figure out whether or not you will be demoted or promoted. 

If you receive under 15 LP after each match, you will likely be demoted from your current rank and moved to a lower division.

It also means your MMR is lower than that of the average player in your division.

Earning 18 – 25 LP after each match means you are in the sweet spot and belong exactly where you are, i.e., playing against opponents with a similar MMR as yourself.

Your MMR will also be around the average MMR for a player in your division.

Finally, earning 25 or more LP per match means your MMR is much higher than the average player in your division, and you can expect to jump to a higher division and climb the ranked ladder quickly.

Once you reach an average MMR that matches your own, the amount of LP you should expect to earn between 18 – 25 LP after each match.

Teammate and Opponent MMR

Do you find yourself playing against opponents whose ranks are frequently higher than your own?

Or are your teammates several divisions below you? How do you know?

To get the best idea of how your MMR and rank fit in with your teammates and opponents, you should look at the ranks of the people you played with and against for your last ten games. 

If they are regularly lower than your rank, your MMR is also likely quite low, and you will only be gaining a few league points after each of your matches.

On the other hand, if your opponents and teammates are typically higher than you, that means the game is trying to bring you and your MMR up to a higher level. 

Dodging and Decaying Effects on MMR

Did you know that neither decaying nor dodging affects your MMR?

While you may drop several divisions if you accidentally decay (LP loss due to being inactive) and will take an LP hit when dodging games, your MMR will remain unaffected. 

So if you accidentally dropped several divisions due to decay, your LP gain will be higher than normal until you get to a higher rank due to your MMR being the same as before the decay.

It also means you do not have to worry about losing MMR when dodging League games.

How to Improve Your MMR

Now that you know how to get a general idea of what MMR is, you should know how to improve your MMR and move up the ranks quickly and efficiently.

You can use several techniques to increase your MMR over time, though it will take time and effort to see a substantial increase.

  • Winning Games: This one is obvious, as a player’s MMR goes up when on a winning streak. A high win rate is the best way to quickly fly through the lower ranks and increase your current MMR.
  • Dodge Games You Won’t Win: Sometimes, there are games we know are lost before we even start them. It is better to dodge that game and take the slight LP hit in those cases. Remember, your MMR will not be affected if you dodge a game. 
  • Losing Streak? Stop Playing Ranked: If you find yourself on a losing streak while playing Ranked games, take a break from playing Ranked. Play some friendly games with your friends, or do something else to get back into a better headspace. After all, your mentality is half the battle in competitive gaming. Go back to playing a ranked match again when you’re ready.
  • Duo Queue: Playing with a higher-ranked teammate with a good MMR rating can help you increase your MMR faster than if you play on your own. The League of Legends MMR algorithm considers the average MMR of your team, so if you queue with higher-ranked players, you will gain more LP after each match. 

Conclusion

League of Legends makes checking your MMR quite difficult, and while you can never know your exact MMR, you can still have a general understanding of it.

FAQ

Here are the answers to some more FAQs about MMR in LoL.

Do the different Game Modes Have Different MMRs?

Each game mode in League of Legends comes with different MMRs. So while you may have a low MMR in ranked solo or duo games, you may have a much higher MMR in Flex Queue team games or even ARAM.

The normal games a lot of people think are the most important thing to rank in are the solo-ranked games.

What does ARAM mean in LOL?

ARAM is short for “All Random, All Mid.” It is a single-lane game mode between two teams of five players, where each player is assigned a random champion.

Why am I Being Thrown Against Such High-Ranked Players?

If you have created a new account and are a higher-ranked player on your main account, you may be placed in the Smurf Queue. The Smurf Queue is made of other smurfs who have won many games in a row quickly, forcing them to battle against one another. 

Will My MMR Change After a Single Game?

No, your MMR will not change after a single game. It takes multiple games for a substantial change to happen to your MMR.

If you want to check if your MMR has changed, I recommend playing between 10 – 20 games before checking it from the last time you checked. 

How is MMR Determined?

Many different metrics determine MMR that Riot Games has not made clear to its player base.

However, it is likely in some way related to the same metrics that decide what champion ranks you get after each match.

Is there a big difference between platinum vs. diamond players in LoL?

Both platinum and diamond require a high MMR rating and are only exceeded by Master, GrandMaster, and Challenger rankings.

The precise percentile for each rank changes all the time. So I can only give a rough estimate.

But as a rule of thumb, Platinum players (Platinum IV-I) are in the top 8-10 percentile, while diamond LoL players (Diamond IV-I) are in the top 1.5-2 percentile.

To be a challenger player (the highest rank possible), you must be among the top 0.010 percentile. Good luck with that one!
