Frequently Asked Questions

How accurate are these calculators?

Our calculators use the official LP system from League of Legends (100 LP per division, ~20 LP per win) and statistical models based on winrate. Actual results may vary based on your MMR, but estimates are typically within 10-15% of reality.

What does the Rank Climb Calculator show?

The Rank Climb Calculator estimates games needed, daily pace, and success probability from your current rank/LP to a target — including live Grandmaster and Challenger cutoffs when you aim for apex.

Do these tools require my Riot account?

Optional. You can type rank and LP by hand, or look up your Riot ID to autofill Solo/Duo rank, LP and winrate. Apex climbs also pull live Grandmaster / Challenger cutoffs for the server you pick.

How is winrate calculated?

You can find your winrate in your League client profile, or on sites like OP.GG, U.GG, or Mobalytics. We recommend using your recent ranked winrate (last 20-50 games) for the most accurate predictions.
