OSRS Combat Calculator

Official OSRS combat formula — style detection, stat breakdown, next-level planner, and target combat level gap.

How It Works

  1. Enter all seven stats. Attack, Strength, Defence, Hitpoints, Prayer, Magic, and Ranged (1–99).
  2. Get combat level. Uses the official OSRS formula with optional HP estimation from combat stats.
  3. Detect build style. See whether you're Melee, Ranged, or Magic dominant — Pure, Zerker, or Main.
  4. Plan next level. Find the fastest skill path to reach the next combat level.
  5. Target level. Enter a goal combat level to see the gap and estimated skill levels needed.
