League of Legends Rank Calculator
Estimate how many games, what win rate, and how much time you need to reach your target rank using your current LP gains and losses as a practical MMR proxy.

Time assumptions
35 min/gameNet expected LP/game: +7.00
Break-even win rate: 44.4% (loss LP / (win LP + loss LP))
Riot keeps hidden MMR private. These projections use your observed LP gains and losses as the best available proxy, so actual climb results can vary.

How EloFactory estimates your League climb
The calculator maps each visible rank to an absolute LP scale, then uses your LP per win, LP per loss, and win rate to project your average climb. It is a planning tool, not an MMR checker, because Riot does not publish hidden MMR.
Absolute LP
Iron IV starts at 0 LP, each division adds 100 LP, Master starts at 2800, Grandmaster at 3000, and Challenger at 3500.
Expected LP
Average LP per game is win rate times LP gained, minus loss rate times LP lost. If that value is zero or negative, the climb stalls on average.
Time plan
Time uses your game, queue, and break assumptions. Change them to compare a fast solo queue session with a slower schedule.
Ranked rules this estimate respects
Riot's ladder moves from Iron through Diamond divisions, then Master, Grandmaster, and Challenger. Promotions happen at 100 LP, and extra LP carries over to the next division or tier.
Demotions, placement games, Master+ leaderboard cutoffs, and Diamond+ decay can affect real outcomes. The calculator flags the main risks but keeps the projection focused on your current LP inputs.
