How to Calculate MMR in League of Legends

In League of Legends, as with many other online multiplayer games, players aim to ascend the ranked ladder and enhance their Matchmaking Rating (MMR). Yet, ever since the inception of the MMR system, players have grappled with the challenge of accurately determining their MMR. This is largely because it’s a concealed numerical metric that gauges a player’s skill and affects their matchmaking opponents.

Given the intricate and hidden nature of MMR, there’s no official method to calculate it with certainty. However, various third-party applications offer estimates of your current MMR.

What is MY MMR IN LOL?

MMR, or Matchmaking Rating, is a complex algorithm that is behind your Rank and Division. It’s the puppet master behind matchmaking, ensuring you’re not playing against Faker when you’re just starting out. Think of MMR as your personal progress bar in the game.

How to know your MMR in League of Legends?

Riot doesn’t disclose it, but third-party platforms like WhatismyMMR offer rough estimates which are maybe close but we will never know for sure. Maybe in the future LoL will decide to show players their Match Making Rating but at the moment we just got it in a lot simpler way of having “Divisions” which is a well working system with the whole algorithm of MMR behind it!

What Influences MMR?

Contrary to popular myths, MMR isn’t swayed by your individual performance or the skill level of your opponents. It’s all about the outcome of your ranked games, as sad as it sounds you do have to win to gain it and lose to lose it.

Does MMR ever reset?

In terms of MMR resets in League, it doesn’t undergo a full reset but experiences what’s known as a “soft reset” at the beginning of each new ranked split. This means your MMR is partially recalibrated, usually pulling you closer to the average MMR for the player base. It’s Riot Games’ way of leveling the playing field while still acknowledging past performance. So, while your MMR doesn’t go back to square one, it does get adjusted to set the stage for the new season.

How to Calculate MMR

As we’ve previously noted, there’s no foolproof method for determining your MMR in League of Legends, given its hidden nature. While some approaches claim to reveal your MMR, their accuracy is often questionable, making them less than reliable.

One approach is to analyze your match history. If you consistently find yourself matched against or alongside highly-ranked players, it’s likely that your MMR is on the higher end. Additionally, the amount of LP you gain or lose post-match can offer some clues about your estimated MMR. 

Another more straightforward method involves using third-party platforms that extract data from the game’s API. Websote like and WhatismyMMR, however this platform is merely making educated guesses based on available statistics, so it’s wise to take their findings with a grain of salt,  what’s also cool about it, is that it also gives you your normal games MMR as well as ARAM MMR.

What is the difference between MMR and ELO?

While MMR and ELO share similarities, they serve different purposes. Elo is a specific numerical rating system, whereas MMR is a more comprehensive metric that takes into account multiple factors beyond just a numerical rating. In League of Legends, MMR is the backbone of the matchmaking system, influencing LP gains and losses, division assignments, and overall progression in rankings.

A key distinction between the two is visibility. While games that use Elo make it openly visible, MMR remains hidden from players. Riot Games, the creators of League of Legends, made the switch from displaying Elo to keeping MMR under wraps. This change was implemented to alleviate player stress and ladder anxiety tied to specific numerical ratings, allowing gamers to concentrate more on the overall competitive journey rather than obsessing over a single number. One commonality between Elo and MMR is that both can be effectively improved with the help of FFBoost15’s boosting services.

MMR vs ELO

Before MMR became the standard, ELO was the go-to system. Riot transitioned to MMR to make matchmaking more balanced and less stressful which is totally understanble.
