LoL MMR Checker
Type a summoner name and see exactly what hidden MMR that account is sitting at.
How the MMR Checker Works
The checker estimates your hidden MMR based on your rank, division, LP, and how the current Season 2026 ladder is distributed on your server. Every region has its own MMR-to-rank mapping, and the formula accounts for that.
Server Specific
Gold II on EUW sits at a different MMR than Gold II on KR. The checker uses current Season 2026 distribution for each server separately.
Season 2026 Ready
MMR-to-rank mapping was recalibrated in January 2026, with an Apex tier reset on April 29. The checker reflects the current ladder, not last year's numbers.

What Is My MMR and Why It Matters
MMR stands for Matchmaking Rating. It is the hidden skill number the system uses to pick your opponents and set your LP gains, and your visible rank, whether it is Silver II or Diamond IV, is just the badge sitting on top of it.
Each mode has a separate MMR. Solo/Duo, Flex, normal draft and ARAM all track independent ratings, so a bad streak in one does not bleed into another. Two exceptions. Your first ranked placement on a new account uses your normal game history as a starting point, and since Season 2026 Riot pulls Flex ranks closer to Solo/Duo, while Flex never pulls Solo/Duo up.
If your MMR has sunk well below your rank, a fresh lol smurf starts over from placement instead of dragging that history along. And if you are weighing whether the old account is worth keeping, the account value calculator puts a market price on it in about a minute.
Hidden MMR vs. Your Displayed Rank
Most players treat MMR and rank as the same thing, but they are different systems. Your displayed rank is the Silver II or Gold IV badge you see on your profile, and it only moves when you rack up enough LP to promote or when you lose enough to demote. Your MMR moves after every single game. This is why two players in the same rank can have completely different climb speeds. One gets +24 LP per win and loses only −16, climbing out of the division in a week. The other grinds +13 and −22 for a month without moving. Same rank on paper, very different hidden ratings. If you want to see whether your hours tell the same story, the Wasted on LoL tracker shows how your playtime stacks up against the median at every rank.
How LP Gains Actually Work
When you gain 14 LP per win and lose 22, your MMR is sitting below your visible rank. Take a Gold IV player with Silver II MMR. Matchmaking puts them in Silver lobbies, and the LP math keeps pulling the rank down toward the MMR until both line up. Players call this MMR hell, but nothing about it is rigged. Closing the gap takes roughly a 60% winrate across 30 to 40 games. The first 10 feel slow because gains sit around +14, and by game 30, if the winrate holds, they drift up to +20 or +22 and the rank starts moving again.
Two things can make your LP look off even when your MMR is fine. Server is one, EUW and KR tend to run tighter gains than NA, where lobbies outside the top tiers are looser. Autofill is the other. If a friend gained 40 LP on the same game you got 18, they were probably autofilled, because Aegis of Valor doubles LP on an autofilled win. Since patch 26.15 it no longer shields an autofilled loss, more on that in the 2026 changes below.

What Changed for MMR in 2026?
Every 2026 change that touches your hidden rating or your climb, oldest first.
- JAN 2026JAN 2026
MMR-to-Rank Recalibration
At the start of the season, Riot redid how MMR maps to ranks. The biggest change was Iron, which collapsed from around 14% of the player base to 3.4% on the August 2026 snapshot. Low-skill players who used to sit in Iron now land in Bronze, and the upper Diamond tier was compressed with the top Diamond players pushed into Master. The middle of the ladder now sits in Gold, which is the largest tier at roughly 24% of the ladder, with the median player landing around the Gold II to Gold III boundary.
- PATCH 26.3PATCH 26.3
Climb Indicator
A UI badge was added that appears next to player names when their hidden MMR is higher than their displayed rank. It shows up in champion select and loading screens. This is the first time the hidden rating has been visible to other players, even indirectly. The checker above gives you the actual number behind that badge.
- APR 29 · PATCH 26.9APR 29 · PATCH 26.9
Apex Tier Reset
A hard reset of all Master, Grandmaster, and Challenger accounts in North America, Europe, Brazil, Latin America North, and Turkey hit on April 29. Everyone in these tiers dropped to Master 0 LP and rebuilt from scratch. New LP cutoffs were set at 800 LP for Challenger and 400 LP for Grandmaster. Korea, China, OCE, Vietnam, LAS, Japan, and Russia never got the reset, and Riot has not announced one for them.
- MAY 12 · PATCH 26.10MAY 12 · PATCH 26.10
Griefed Games Can End Without LP Loss
When someone in your game is confirmed griefing, the rest of the lobby can now vote to end it early. Nobody on the clean side loses LP or MMR, winners still get paid, and the griefer eats a ban. If you ever finish a loss and your LP does not move, this is why. Patch 26.11 also fixed a bug where that consolation LP sometimes did not pay out after ended games and AFKs.
- JUL 29 · PATCH 26.15JUL 29 · PATCH 26.15
Aegis of Valor Now Only Pays on Wins
Riot rebuilt Aegis of Valor in patch 26.15. The loss protection is gone and the mastery grade requirement went with it, so an autofilled win doubles your LP with no grade needed, and an autofilled loss now costs the full amount. Riot's reasoning was that the old grade threshold handed players a second objective, playing for the score instead of playing for the win. If you got autofilled, lost, and dropped full LP where you used to drop none, this is why.
- JUL 29 · PATCH 26.15JUL 29 · PATCH 26.15
Duo Locked Out of the Top of the Ladder
The same patch tightened duo queue at the top. Master players can still duo, but only with someone close to them in rank. Grandmaster, Challenger, and anyone carrying GM or Challenger MMR cannot duo at all, even while their visible rank sits lower. Riot said the player pools up there are small enough that a duo swings match quality more than the matchmaker can offset.

Ranked 5s Came Back for a Second Run
The summer run closed on September 6 and Riot said its rewards land with patch 26.18. The second run started September 11 and goes to January 7, 2027, Friday through Sunday from 16:00 to 02:00 server time, a wider window than the summer one. Riot says the first five placement games borrow MMR from your other queues to find opponents, and after that the mode runs its own MMR and LP ladder, so the rank you build there is a separate thing from your Solo/Duo rating. There is still no public queue ID, so the checker stays on Solo/Duo, Flex, and Normal. Full breakdown in our Ranked 5s guide.

Harsher Dodge Penalties at High Elo
Dodging no longer resets your autofill status, the role carries over to your next match. At Master and above a dodge counts as a full loss now, which means MMR drops alongside the LP penalty. Below Master, MMR is still untouched, only LP and the queue lockout apply.

Type your summoner name with its tag (for example Faker#KR1) into the checker above, pick your server from the dropdown, and press Check MMR. The result appears in a few seconds. You can also check a friend's or opponent's account the same way, no login or account connection needed.
The checker is accurate within about 50-100 MMR in most cases. Your rank, division, and LP on a given server map to a fairly narrow MMR band, so the number can be pinned down closely. Fresh accounts with only a few ranked games, or players mid climb between divisions, have a wider margin.
Your hidden MMR is the skill rating the matchmaking system uses internally to match you with opponents and to decide how much LP you gain or lose. The client never shows the number, but it is what really decides your matches. A Silver II player can have Gold-level MMR, or the other way around, and that mismatch is exactly what the checker reveals.
Yes, the checker works for every major region: EUW, EUNE, NA, KR, BR, LAN, LAS, OCE, JP, TR, RU, ME, SEA, TW, and VN. Each server has its own MMR-to-rank distribution, so the checker switches to the right per-region math when you pick a server.
Riot has never published official MMR numbers, so every band you see anywhere is an estimate, ours included. As of Season 2026 our rough bands are: Iron 600-900, Bronze 900-1200, Silver 1200-1500, Gold 1500-1800, Platinum 1800-2100, Emerald 2100-2300, Diamond 2300-2600, Master 2600 and above. These are averages across servers, individual thresholds vary by region, and the whole scale shifts after every season recalibration.
For most ranks no. Dodging costs LP and triggers a cooldown, but your hidden MMR stays the same from Iron through Diamond. Season 2026 changed this at the top of the ladder. At Master and above a dodge counts as a full loss, so MMR drops alongside the LP penalty, and the autofill role carries over to your next match. Full breakdown of penalties and Apex tier rules in our LoL Dodge guide.
Not directly. There is no built-in MMR reset, and changing regions or transferring accounts does not wipe it either, your hidden rating follows your account. The only practical way to start with a clean MMR is a new account. Since 2026 there is only one full rank reset per year, in January. Seasons 2 and 3 carried rank, LP and MMR straight over with no placements, the April apex reset in a few regions being the one exception.
After every ranked game. A win raises your MMR, a loss lowers it, and the size of the change depends on the gap between your MMR and your opponents' MMR. Normal and ARAM games have their own separate MMR that does not affect your ranked rating.
No. League Classic launched July 29, 2026 with no ranked queue at all. Progression runs through Summoner's Journey (Salt up to Legend), not an MMR ladder, and it sits on a separate Classic account track that does not touch your live rank. Riot also confirmed on July 28, the day before launch, that Classic match data is not served through the Riot API at all, so no checker or tracker can read a Classic MMR. If a site claims to show your League Classic MMR, it is guessing.
Ranked 5s runs its own ladder. Riot says the first five games are placements that borrow MMR from your other queues to find opponents, and after that the mode has its own MMR and LP progression, so the rank you build there sits apart from Solo/Duo and Flex. It also has its own season, which means you cannot earn the Victorious skin or the other ranked season rewards through it, though the games do count toward Battle Pass objectives and XP. The second run goes from September 11, 2026 to January 7, 2027, Friday through Sunday, 16:00 to 02:00 server time. There is still no public queue ID, so the checker stays on Solo/Duo, Flex, and Normal.
No. The matchmaking system does not track win or loss streaks when building games, it only uses MMR. Lead gameplay designer Phroxzon confirmed this publicly in 2024: "Losers queue doesn't exist. For ranked, we match you on your rating and that's all." The feeling of losers queue is confirmation bias during tilt plus slightly lower MMR opponents after a loss streak.
Yes. The checker only reads public match data, the same data any player can see in the game client. You never enter a password or log in with your Riot account, and nothing is stored on our side. Checking another player's MMR is not against the game's Terms of Service.
