If you’ve noticed your LP gains shrinking after wins, you’re not alone. This is one of the most common frustrations in League of Legends ranked play. The root cause almost always ties back to the hidden matchmaking rating (MMR) system. Understanding how MMR interacts with your visible rank is the key to diagnosing and eventually fixing low LP gains.
MMR is a numerical value that represents your actual skill level as determined by the game. Your visible rank (e.g., Gold 2, Platinum 4) is just a cosmetic representation. LP gains and losses are designed to pull your visible rank toward your MMR. When your MMR is higher than your visible rank, you gain more LP per win and lose less. When your MMR is lower than your rank, the system tries to correct that by reducing LP gains and increasing losses.
Factors That Reduce LP Gains
Several specific scenarios can cause your MMR to lag behind your visible rank. Each one rewards fewer LP per victory.
MMR vs. Visible Rank Mismatch
The most straightforward reason is that your MMR is simply lower than your current division. This often happens if you had a significant loss streak before a win streak, or if you were stuck in a lower division for a long time while your rank climbed due to lucky wins or a strong duo partner. The system suspects you don’t truly belong at your current rank, so it restricts LP gains to prevent you from climbing too quickly beyond your demonstrated skill level.
Rank Tier Thresholds
Near the top of a tier (e.g., Gold 1, Diamond 1), LP gains can temporarily drop as the game tests whether you are ready to promote to the next major tier. This is a form of clamping. The system wants confidence that you can consistently compete at the higher level, so it slows your progress, making the promotion series feel more earned.
Demotion Protection
When you first promote to a new division (especially a new tier like going from Silver to Gold), you receive demotion protection. You cannot immediately demote from 0 LP unless your MMR drops far below that division. However, this protection can cause an MMR deficit because your visible rank stays inflated while your MMR continues to drop on losses. As a result, once the protection fades, your LP gains will be low and losses high until the MMR gap closes.
Win/Loss Streaks and Recent Performance
The system takes recent match history into account. If you won several games in a row against players with lower MMR than you, your MMR may not have increased as much as your LP. Conversely, a string of losses can tank your MMR faster than your visible rank falls, creating a deficit that leads to reduced gains later. The game tries to smooth out volatility, so a hot streak followed by normal play can trigger smaller LP rewards.
Queue and Duo Disparities
If you frequently play in a premade with a friend who has a much higher rank, the matchmaker will balance by placing you against opponents closer to the higher rank. Your personal MMR may not be high enough for those matches. Even if you win, your MMR gain may be muted because the system attributes some success to the carry. Similarly, if you duo with a much lower-ranked friend, your team’s average MMR drops, making wins less valuable for your own MMR progression.
Role and Performance Metrics
Riot has confirmed that individual performance within a game has a minor influence on MMR changes. While it’s not as impactful as winning or losing, consistently underperforming relative to your rank can slightly depress your MMR over time. This effect is small but can contribute to a slow drift in your LP gain eventually.
How to Improve Your LP Gains
Unfortunately, there is no instant fix. You must play enough games for your MMR to catch up to your rank. Here’s how to accelerate the process:
- Focus on consistent winning – A true positive win rate over many games is the only reliable way to raise your MMR.
- Avoid duoing with large rank gaps – This can distort your MMR progression and lead to lower gains.
- Play your best role and champion – Performing well can slightly boost your MMR per win.
- Don’t dodge games – Dodging hurts your MMR indirectly by wasting time and potentially putting you in tougher matchups later.
- Take breaks after loss streaks – Prevention is better than cure; avoid tanking your MMR in the first place.
Frequently Asked Questions
Why am I gaining 12 LP per win and losing 20?
This indicates your MMR is significantly lower than your visible rank. The system believes you are ranked too high and is trying to demote you to your appropriate level. To fix this, you must maintain a positive win rate over a large number of games.
Does my LP gain reset at season start?
No, LP gains and MMR carry over between seasons, though there is a soft reset. Placement matches adjust your rank closer to your MMR, but if you had bad MMR in the previous season, you may still see lower gains initially.
Can dodging champion select affect my LP gains?
Dodging itself only reduces your LP by a small amount and does not directly harm MMR. However, frequent dodges can delay games, and if you dodge when you would have lost, you haven’t given your MMR a chance to drop, which might temporarily exaggerate the gap.
Why do I gain less LP when I duo with a lower-ranked friend?
The game matches against teams with average MMR below your solo MMR. Winning these games awards less MMR because the expected outcome was for you to win. The risk-vs-reward is skewed against you.
Is there a way to check my MMR?
Riot does not make MMR public. Third-party sites estimate it based on your match history, but they are not official and can be inaccurate. The best indicator is your LP gain and loss pattern.
How many games does it take to fix low LP gains?
It varies. If you consistently win around 55-60% of your games, you might see improvements after 30-50 games. The larger the MMR gap, the longer it takes.
