Frequently asked questions
How is this calculated?
Pure LP arithmetic: every division is 100 LP and there are no promotion series anymore. Your expected LP per game is winrate × LP gained minus loss rate × LP lost; total LP needed divided by that gives the expected games. It's an average — win streaks will land you under it, loss streaks over it.
Is this an MMR calculator?
No. Riot doesn't expose matchmaking rating, and Riot's policies don't allow third-party MMR or ELO estimates. This tool only does math on the visible LP system — the official ranking.
How much LP do you gain per win?
Usually 18–30. Big gains and small losses mean the system is pushing you upward; the reverse means you're above where it places you. Check your last few ranked games and enter your real averages for the best estimate.
Do promotion series still exist?
No — Riot removed division promos in 2023 and tier promos in the 2024 season. Climbing is purely LP now, which is exactly why this calculator can be accurate.
