League of Legends Win Rate Calculator
Calculate your current win rate and find out how many wins you need to reach your goal.
How Your League of Legends Win Rate is Calculated
In League of Legends, your win rate is a primary indicator of your performance relative to your current MMR (Matchmaking Rating). The basic formula is straightforward: (Total Wins / Total Games Played) × 100.
However, many players want to know more than just their current status. They want to know how many consecutive games they need to win to reach a specific milestone, such as a 55% or 60% win rate, which usually indicates a strong climb through the ranks.
The Math Behind the Climb
To calculate how many consecutive wins are required to reach a target win rate, we use the following algebra:
Let W be your current wins, L be your current losses, and T be your target win rate (as a decimal). We want to find G (games to win in a row) such that:
(W + G) / (W + L + G) = T
Solving for G, the formula becomes: G = (T(W + L) – W) / (1 – T)
Examples of Win Rate Calculations
- The "Coin Flip" Player: If you have 50 wins and 50 losses, your win rate is 50%. To reach a 60% win rate, you would need to win 25 games in a row without a single loss.
- The High Volume Player: If you have 500 wins and 480 losses, your win rate is 51.02%. Even though you are positive, reaching a 55% win rate would require winning 87 games in a row, because the total games played (980) makes the win rate harder to move.
Why Win Rate Matters for MMR
Your win rate directly influences your LP (League Points) gains and losses. If your win rate is significantly above 50%, the system recognizes you are likely below your skill bracket and will grant you more LP per win and take away less LP per loss. Maintaining a win rate above 53% over 100+ games is usually sufficient for a steady climb to higher tiers like Emerald, Diamond, or Master.
