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 decide your matches and calculate LP gains for every ranked game you play. Your visible rank, whether it is Silver II or Diamond IV, is just a simplified summary of this number. The rank only moves when you cross an LP threshold. Your MMR updates every single game, win or lose, and the system treats it as the real number, not your rank badge.
Each mode has a separate MMR. Solo/Duo ranked, Flex ranked, normal draft, and ARAM all track independent ratings, and a bad streak in one mode does not bleed into another. Two exceptions. Your first ranked placement on a new account pulls your normal game history to set a starting point, and since Season 2026 Flex MMR gets pulled toward your Solo/Duo rating over time, though Flex never drags Solo/Duo in either direction. Riot hides MMR on purpose. Showing the exact number would make every loss feel worse, give boosters exact data to work with, and push high-MMR smurfs to deliberately tank their rating to avoid queue times.
Players who hit that wall often start over on a fresh lol smurf where MMR begins clean from placement. 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 use these two words interchangeably, 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 invested tell the same story, the Wasted on LoL tracker shows how your playtime compares to 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. The matchmaking system has decided you belong a tier lower, and the LP math reflects that gap. Take a Gold IV player with Silver II MMR. Matchmaker pairs them against Silver opponents, so wins look easy on paper and pay small while losses look like upsets and hit hard. The pattern keeps pulling your rank down toward your MMR until both line up again. Some players call this MMR hell, though nothing about it is secret or rigged. It is just matchmaking math doing its job. Closing that gap takes roughly a 60% winrate across 30-40 games. The first 10 feel slow because LP gains stay stuck around +14. By game 30, if the winrate holds, gains drift up to +20 or +22 and the visible rank starts moving again.
Three things make this faster. Play champions you already know, now is not the time to learn new picks. Duo with a friend who is a division above you on a hot streak, since higher lobby MMR means bigger LP gains for you. And stop playing after two or three losses in a row, tilt costs you more MMR than any single bad game would. Server matters too. EUW and KR run tighter LP gains on average because more players are stuck in Gold through Diamond and competition is sharper. NA is lighter, with looser lobbies outside the top tiers. The same MMR produces different LP patterns depending on where you play.
One Season 2026 quirk worth knowing. Autofilled players with a mastery grade of B or higher earn double LP on a win via Aegis of Valor. If a friend gained 40 LP on the same game you got 18, they were probably autofilled. Not a bug.

What Changed for MMR in 2026?
Season 2026 brought the biggest set of ranked and MMR changes since the 2023 season format rework. Here is what affects your hidden rating and climb right now.
- 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 roughly 3% globally. 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, 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.
- PATCH 26.3PATCH 26.3
Aegis of Valor
Autofilled players who finish a match with a mastery grade of B or higher get either double LP on a win or full LP protection on a loss. The grade threshold was raised from C to B in patch 26.3. Support and jungle mains who rarely get autofilled still get the reward at the same rate in the background, without a lobby notification.
- 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 later confirmed no other region will.
- 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.
- ONGOINGONGOING
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. It is not shown in the client, but it is what really decides your matches, not your visible tier. 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 rank reset per year, in January. The Acts during the year carry your rank, LP, and MMR over with no mid-year placements.
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. 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.
