What is MMR?

MMR (Matchmaking Rating) is a hidden value that Riot Games uses to match players of similar skill levels in ranked games. Unlike your visible rank, MMR is not displayed anywhere in the game client.

How MMR Affects Your Games

Your MMR determines:

  • Who you're matched against in ranked games
  • How much LP you gain or lose per game
  • Your overall rank progression speed

LP Gains and MMR

If your MMR is higher than your current rank, you'll gain more LP per win (typically 20-30 LP). If your MMR is lower than your rank, you'll gain less LP per win (12-17 LP) and lose more per loss.

How to Check Your MMR

Since Riot doesn't show your exact MMR, you can estimate it by looking at your LP gains. Our MMR calculator uses your rank and LP gains to estimate your hidden MMR accurately.

Improving Your MMR

The only way to improve your MMR is by winning games consistently. Focus on:

  • Playing your best champions
  • Maintaining a positive win rate
  • Avoiding tilt and loss streaks
  • Playing during peak hours for better matchmaking

Common MMR Myths

Myth: Dodging games affects your MMR.
Truth: Dodging only costs you LP, not MMR.

Myth: Playing more games raises your MMR.
Truth: Only winning games raises your MMR, not game quantity.

Conclusion

Understanding MMR is crucial for climbing the ranked ladder efficiently. Use our MMR checker regularly to track your progress and adjust your strategy accordingly.
