What Is My MMR? LoL MMR Checker

Updated November 7, 2026

MMR (matchmaking rating) is the hidden rating Riot uses to match your ranked games — never shown in client and not readable via any API. This free checker estimates your MMR from the gap between your average LP per win, your average LP per loss and your recent win rate: no login, works for all regions, nothing sent to any server. Enter the numbers below and you'll get an MMR estimate in rank terms, a numeric MMR range on our open scale, plus projected LP per win/loss with wins to your next division.

Pick your current Solo/Duo rank, enter your average LP per win and per loss, your win rate over the last 20 games and how many ranked games you played this season. The result shows whether your MMR is above, level with or below your rank, roughly which rank it points to, and the corresponding numeric MMR range.

How does this MMR checker work?

It compares your average LP gain with your average LP loss. When wins pay more than losses cost, the system is pulling your rank up, which means your MMR is higher than your badge. The bigger the gap, the further above. This is the exact scale the calculator uses:

LP per win divided by LP per loss	MMR compared with your rank
1.8 or more	About 4 divisions above
1.5 to 1.79	About 3 divisions above
1.3 to 1.49	About 2 divisions above
1.15 to 1.29	About 1 division above
0.95 to 1.14	Level with your rank
0.8 to 0.94	About 1 division below
0.65 to 0.79	About 2 divisions below
Under 0.65	About 3 divisions below

Win rate then nudges the result: 60% or more adds a division, 55% or more adds half a division, 45% or less takes half a division away, and 40% or less takes a full division away. The total is rounded and added to your rank to give the estimated MMR rank. Games played sets the confidence: under 20 games is low, 20 to 49 medium, 50 or more high.

Quick example. You are Gold III, winning +30 and losing -18 on average with a 58% win rate over 60 games. The ratio is 1.67, so three divisions up, plus half a division for the win rate, rounded to four. The checker points to Platinum III with high confidence.

No account lookup, no login and no data leaves your browser (the math runs on the page itself). The estimate uses only the numbers you type in, so the more games behind your averages, the more you can trust it.

How we estimate numeric MMR

Riot never publishes MMR numbers. Our open scale maps the estimated MMR rank from the table above to a numeric range, using 100 MMR per division as the step. Every number on this page is an estimate, not a reading from Riot's servers.

Rank	Estimated MMR range
Iron IV → Iron I	400 → 700
Bronze IV → Bronze I	800 → 1,100
Silver IV → Silver I	1,200 → 1,500
Gold IV → Gold I	1,600 → 1,900
Platinum IV → Platinum I	2,000 → 2,300
Emerald IV → Emerald I	2,400 → 2,700
Diamond IV → Diamond I	2,800 → 3,100
Master	3,200 → 3,350
Grandmaster	3,400 → 3,550
Challenger	3,600+

So Platinum III at the base of the tier maps to around 2,100 MMR estimated, and a result like "four divisions above Gold III" points at the same 2,100 MMR estimate. The ±100 band is the confidence envelope: if your sample is under 20 games, widen it to ±200. These are our numbers, published openly so you can check the math — not Riot's.

LP projection: what to expect per game

Once the checker has your estimated MMR, the same inputs give a projection of what the next win and the next loss will pay, plus how many wins until your next division. The logic is the one documented in our LoL climb calculator; here it is in short form.

• Expected LP per win: about 20 at parity (MMR level with rank), rising toward 30+ when MMR is above rank and falling toward 10 when MMR is below.
• Expected LP per loss: about 17 at parity, falling toward 10 when MMR is above rank and rising toward 25+ when MMR is below.
• Wins to next division: (100 − your current LP) divided by expected LP per win, rounded up. With a 55% win rate the games-played multiple is roughly 1/0.55 of that number.

Open the climb calculator for the full matrix (current rank + target rank + win rate) and a per-game projection. The MMR checker gives you the starting point; the climb calculator walks the climb.

What is MMR in League of Legends?

MMR, or matchmaking rating, is the hidden number Riot uses to rate you and decide who lands in your lobby. Your rank, from Iron to Challenger, is just the badge the client shows you, driven by LP. The two usually sit close together, and when they drift apart, LP gains and losses change to pull your rank back toward your MMR.

Ever wondered why two players with the same badge can have completely different seasons? One Gold II gains big LP and plays against Platinum players, the other gains little and plays against Silver. Same badge, different MMR (and a very different climb).

What does the MMR checker need from your LP history?

Write down the LP change after each ranked game for 15 to 20 games (or read it from your match history on a stats site). That is all the checker needs. The patterns look like this:

• Big gains, small losses: your MMR is above your rank and you are about to climb.
• Gains and losses about even: your rank matches your MMR.
• Small gains, big losses: your rank got ahead of your MMR and the system is pulling it back.

Put simply, one game tells you nothing and twenty tell you most of the story. Use averages, not your last result.

Why are you gaining so little LP?

Usually because your rank is ahead of your MMR, and the system is quietly correcting the difference one game at a time. Honestly, it is rarely bad luck. A lucky streak, a strong duo or a run of games where the other team had a disconnect can push the badge up faster than the hidden rating. Then every game pays a bit less and costs a bit more until the two meet again.

The fix? Boring, but it works: win more than you lose at your current rank. As your MMR catches up, the gains grow and the losses shrink. Run the checker again after another 20 games and you can usually see the ratio move.

What does and doesn't change your MMR?

Winning and losing ranked games moves MMR. Plenty of other things people worry about don't:

• KDA and damage: League doesn't hand out extra LP for a big scoreline. The result of the game is what counts.
• Normal games: they have their own matchmaking, separate from ranked.
• Remakes: a remade game doesn't count as a ranked win or loss for the players who stayed.
• Dodging: costs LP and a queue timer (more for repeat dodges), but you didn't play a game, so it doesn't count as a loss for MMR.

For what it's worth, the biggest MMR swings come from streaks. Five wins in a row move your rating faster than five wins spread over ten games, and a five-game loss streak tanks it just as hard, which is why you should stop after two losses in a row.

Riot explained how ranked and MMR work this season in the video below.

How do you raise your MMR?

Real talk, there is no trick. Winning is what moves MMR, and a few habits make winning more likely:

• Play a small champion pool. Two or three champions you know inside out beat ten you play now and then.
• Stop when you tilt. Tired late-night games are where streaks of losses come from.
• Duo with care. Matchmaking uses both players' ratings, so a duo far from your level gives you games that fit neither of you.

If you want to see how many wins at your current pace it takes to reach a target rank, our LoL climb calculator breaks it down from your current rank, target rank and win rate.

Before a long session, check the LoL server status and your connection with our LoL ping test, because a disconnect costs the same LP as a real loss.

Can you reset a bad MMR?

Not with a button. The thing is, Riot doesn't offer one, and the season reset only softens the gap. If an account has hundreds of games of losing streaks behind it, climbing out takes a long run of wins at your current rank. Some players prefer a fresh start instead, either by leveling a new account themselves or with one of our hand-leveled LoL accounts that have never played ranked this season. Either way, track your LP for a couple of weeks and run the MMR checker again, so you know whether the rating is actually moving.

How this calculator compares to summoner-name lookup tools

Some MMR sites fetch your data by summoner name and server. The best known is whatismymmr.com. The two tools do different things from different inputs. This table lists what each does, taken from the public pages of both tools, with no judgement of which is better.

Feature	agatasmurf.com MMR checker	whatismymmr.com
Input method	Manual (rank, LP per win, LP per loss, win rate, games played)	Summoner name and server lookup
Queues covered	Solo/Duo and Flex (tabs above)	Ranked Solo, Normal, ARAM
Regions	Region-agnostic (you enter the numbers)	NA, EUW, EUNE, KR
Account access	Nothing is sent anywhere; math runs in your browser	Reads public match history for the summoner you type
Minimum games	Works from the first game; confidence tag reflects sample size	Shows "N/A" until there are enough solo games in the last 30 days
Output format	Rank-level estimate (above / at / below your rank), gain-to-loss ratio, three-level confidence, numeric MMR range from our open scale	Numeric MMR with ±confidence interval, percentile, 30-day trend and distribution charts
API	No public API	Public API documented on their site

Pick whichever matches your situation. If you have an active summoner on a supported region with recent solo games, their lookup saves data entry. If you want to try a scenario or do the math without handing over a summoner name, this one keeps every input on your end.

FAQ

What is my MMR?

Your MMR is the hidden matchmaking rating Riot uses to pair your ranked games. Riot has never shown it in client or via any API, so any number you see is an estimate. This checker gives one by comparing your LP per win and LP per loss plus your win rate; our open scale maps the result to a numeric MMR range.

How do I check my MMR without login?

Enter your rank, your average LP per win, your average LP per loss, your win rate over the last 15 to 20 games and the number of ranked games you played this season. The calculator runs in your browser — nothing is sent anywhere, no Riot ID, no password, no account linking.

Is MMR the same as LP?

No. LP (League Points) is the visible points bar inside your current division: 0 to 100 LP, win adds, loss subtracts. MMR is hidden and sits behind LP: it decides how much LP each win and loss is worth. When MMR is above rank, wins pay more than losses cost; below rank, the opposite.

Does MMR reset each season?

Partially. Riot applies a soft reset at the start of each season, nudging most players a few divisions below their peak but not to zero. From 2026 onward Riot also applies a hard reset at the top of the ladder (apex ranks) to give returning Challengers and Grandmasters more meaningful placements. Your underlying MMR is what gets softly reset, so placement matches place you near the MMR you ended the previous season on.

Can an MMR checker show my exact MMR?

No. Riot doesn't show MMR anywhere, and no site can read it from your account. You can estimate it from your LP gains and losses, which is what this checker does.

How accurate is this MMR checker?

It is an estimate based on the numbers you enter. With 50 or more games behind your averages, confidence is high. With fewer than 20, treat the result as rough.

Does the MMR checker need my Riot ID or password?

No. It only uses the LP, win rate and game count you type in, and nothing is sent anywhere.

Why do I lose more LP than I gain?

Your rank is ahead of your MMR, so the system pulls it back down. Winning consistently at your current rank closes the gap.

Do normal games affect ranked MMR?

No. Normal games use their own matchmaking rating, separate from ranked.

Does dodging lower my MMR?

Dodging costs LP and gives a queue timer, but because no game was played, it doesn't count as a loss for MMR.

Does Flex share MMR with Solo/Duo?

No. Flex Queue and Solo/Duo are separate queues with separate MMR. Winning Flex games does not change your Solo/Duo MMR. Use the Flex tab above to run the same math against your Flex LP numbers.
