You can see your rank and LP on your own profile card, but there’s one more number behind matchmaking that you’ll never see directly: MMR. It’s a hidden rating that decides who you play with and against, and why the same win gives you 15 LP one time and 30 the next. This text follows up on our article about ranks in LoL, where you’ll find the full ladder of tiers and divisions. Here we focus only on the hidden number behind it.
What MMR is and how it differs from your visible rank
MMR (matchmaking rating) is an internal estimate of your skill that League of Legends keeps in the background for every queue you play: one for solo/duo, another for flex, and yet another for normal games, for instance. Riot never displays it as a number and doesn’t publish exactly how it’s calculated. The rank and LP you see on your profile are the public, visible representation of your level. MMR is the real engine under the hood that decides who the game assigns to you as teammates and opponents.
Under normal circumstances the two systems stay close together, and your rank gradually catches up with what the game thinks of you internally. But they can drift apart, and that gap explains a lot of things that look unfair at first glance: why a player with the same rank as you plays very differently, why the system gives you a match that feels lopsided, or why your rank moves more slowly than you’d like.
Why you get more or less LP
LP gains and losses aren’t a fixed number. They reflect how closely your MMR matches your visible rank. When your MMR is higher than your rank, for example because you’re a player returning after a long break or you climbed quickly through the lower tiers, the system gives you more LP for wins and takes less for losses, because it wants to get you to where you belong by its internal estimate as fast as possible. When it’s the other way around and your MMR is below your visible rank, the exact opposite happens: LP gains shrink and losses grow until the two numbers line up again.
This is the most common reason players report “I’m winning and getting less LP than my friend at the same rank”. It’s not a bug or the system being spiteful; their MMR simply doesn’t match the tier shown. A player with low LP gains almost certainly has an MMR at the level of their current rank or lower, while a player whose LP climbs fast has an MMR above their rank, and the system is pulling them up toward it.
What actually affects MMR
Riot has repeatedly explained that the main and practically only input for MMR is the match result: a win or a loss for the team as a whole. According to the official statements, your personal performance within a won or lost match (KDA, farm, damage, number of towers taken) isn’t reflected in MMR directly. The reason is deliberate: Riot wants League to remain a team game where you win and lose together, not a system that rewards solo carry performances at the expense of teamwork.
That doesn’t mean personal performance doesn’t matter at all. Playing well helps you win more matches, and that’s the only way MMR really moves. It just doesn’t work through some hidden bonus formula for good stats inside a lost match.
How MMR works on a new account
A new account has no history, so MMR starts at a neutral, roughly middle value and calibrates quickly based on the first matches you play, mainly during the ten placement games covered in detail in our article about ranks. If a new player’s results are well above expectations, the system pushes MMR up faster than the slow LP climb in regular ranked would suggest. That’s why experienced players on new accounts (typically smurfs) reach higher tiers unusually fast. MMR can adjust much more nimbly than your visible rank, which gradually catches up with it through LP.
How to check your MMR
Riot doesn’t officially display MMR anywhere, neither in the client nor on the official website. What does exist are third-party tools that try to estimate MMR from publicly available data: your rank, LP and match history. They work by estimation, not by direct access to Riot’s data, so treat their result as a rough approximation, not an exact number.
The reliability of these estimates grows with the number of matches you’ve played in the current season and how stable your rank is. On a fresh account or after a long break, the estimate will be much less accurate than on an account with hundreds of matches in a single queue. The best practical indicator you actually have access to yourself is still how much LP you get for wins: consistently low gains point to MMR at or below your rank, consistently high gains to MMR above it.
None of these external tools have access to Riot’s internal data. They only work with what’s publicly visible in your match history. Two different sites may therefore give you slightly different estimates, because they use somewhat different formulas and differently sized samples of matches. Treat them as a hint about whether your MMR is more likely above or below your current rank, not as an exact substitute for the number only Riot’s matchmaking sees.
MMR and what the community calls “elo”
League of Legends doesn’t officially use the term elo. MMR is based on a principle similar to the classic chess Elo rating (the winner takes points from the loser), but Riot’s implementation is its own and adapted for five-player team matches. Even so, the community commonly uses MMR and elo interchangeably as synonyms for the same hidden number. When you come across the phrase “elo hell”, it means exactly this situation: a player feels their MMR doesn’t match their real level and the matches around them only seem to confirm it. The feeling is real subjectively, but objectively it’s more a reflection of natural variance in a small sample of matches than an actual trap in the system.
What to do when matchmaking seems unbalanced
A few matches in a row that feel unbalanced don’t automatically mean the system is broken. MMR works with probability across a large number of matches, not with certainty in any single one. Even balanced matchmaking occasionally produces a game that doesn’t look balanced on paper, simply because the day, form or synergy with a random team can’t be guaranteed in one match. Before drawing conclusions about your own MMR from a few games, it makes sense to watch the trend over dozens of matches, not five.
What definitely doesn’t make sense is dealing with the feeling of unfair MMR by buying a boosted account or paying a stranger to raise your rank. That goes directly against Riot’s rules, can get you penalized up to a permanent account ban, and on top of that only deepens the real problem (the gap between MMR and visible rank), because once the boost is detected, Riot corrects both rank and MMR sharply back down.
What MMR affects besides LP
MMR isn’t just about how much LP you get. It’s the primary input for matchmaking itself: the game tries to pair matches so that the total MMR on both sides is as even as possible, regardless of which rank the players currently have displayed. That’s why you’ll sometimes run into an opponent with a visible rank quite different from yours. Matchmaking doesn’t compare rank, it compares MMR, and those two things sometimes drift apart.
MMR is also calculated separately for each queue. Your MMRs in normal draft, solo/duo and flex are only loosely connected. A good streak in normals won’t raise your ranked tier on its own, because it doesn’t count toward your ranked MMR.
FAQ
A hidden internal rating of your skill that Riot doesn’t display anywhere. It decides who matchmaking pairs you with and against, and how much LP you gain for a win or lose for a loss.
The most common cause is that your MMR is at the level of your current rank or below it. The system then keeps LP gains low until your real performance is clearly proven by a winning streak.
According to Riot’s official statements, not directly. MMR is driven mainly by the result of the match as a whole (win/loss), not by individual stats within the match.
Riot doesn’t officially display it anywhere. There are third-party tools that estimate it from public data, but it’s an estimate, not an exact number. Accuracy improves with the number of matches played in the given season.
No. MMR is calculated separately for solo/duo, flex and normal games, so your performance in one queue doesn’t directly affect your rating in another.
Because after a streak of clear wins their MMR adjusts much faster than the gradual LP gains on the visible rank allow. On a new account, MMR u0022runs aheadu0022 and the rank gradually catches up.
League of Legends doesn’t officially use the term elo, but the community commonly uses it as a synonym for MMR. The principle is similar (the winner takes points from the loser), but the specific calculation is Riot’s own.
No, and on top of that it’s against Riot’s rules and puts your account at risk of penalties. A boosted rank also only widens the gap between your visible rank and your real MMR, which gets corrected sharply back down once the boost is detected.
