OSRS Combat Level Calculator
High-precision calculation utility providing accurate real-time metrics.
Understanding This Calculator
Combat level in Old School RuneScape is a single number summarizing how tough your character is in a fight, derived from your Attack, Strength, Defence, Hitpoints, Prayer, Ranged, and Magic levels. It’s the value shown above every player’s head and it caps at 126 for a maxed combat account.
Unlike a simple average, the formula gives Melee, Ranged, and Magic their own separate “combat contribution,” then only the highest of the three counts toward your final level — so training all three attack styles equally doesn’t raise your combat level any faster than focusing on one.
- Base 0.25 × (Defence + Hitpoints + floor(Prayer/2))
- Melee 0.325 × (Attack + Strength)
- Range 0.325 × floor(1.5 × Ranged)
- Mage 0.325 × floor(1.5 × Magic)
This calculator uses OSRS’s publicly documented combat-level formula (widely published on community wikis); it performs only this factual math and does not reproduce any game text, art, or branding.
What is the OSRS Combat Level Calculator?
The OSRS Combat Level Calculator is a fundamental tool for players of Old School RuneScape who want to understand and optimize their character’s progression. Your combat level is a general indicator of your overall strength and dictates how aggressive NPCs will react to you, as well as which combat brackets you fall into for Player vs. Player (PvP) minigames and Wilderness encounters.
By inputting your current levels in Attack, Strength, Defence, Hitpoints, Ranged, Magic, and Prayer, this calculator determines your exact combat level down to the decimal. It is especially useful for ‘pure’ accounts who want to maximize their offensive stats while keeping their combat level as low as possible, helping them plan out exactly how many levels they can gain without leveling up their overall combat bracket.
How to Calculate Old School RuneScape Combat Levels (The Formula)
Combat level is calculated based on Base Combat and Melee/Ranged/Magic modifiers. Base = 0.25 × (Defence + Hitpoints + Floor(Prayer/2)). The final level is Base + Maximum of [0.325 × (Attack + Strength)] OR [0.325 × (Floor(1.5 × Ranged))] OR [0.325 × (Floor(1.5 × Magic))].
Frequently Asked Questions
Why does training Ranged or Magic alone raise my combat level fastest?
Because only the single highest of Melee, Range, or Mage counts toward your combat level, pure Ranged or Magic training reaches high combat contribution faster per level trained than splitting effort across all three combat styles.
What is the maximum possible combat level?
With every combat skill at 99 (Hitpoints starts at 10 and rises with Attack/Strength/Defence training), the formula produces a combat level of 126, the highest attainable in Old School RuneScape.
What is the maximum combat level in OSRS?
The maximum possible combat level in Old School RuneScape is 126. This is achieved by reaching level 99 in Attack, Strength, Defence, Hitpoints, Ranged, Magic, and Prayer.
Do Ranged and Magic affect my combat level differently than melee stats?
Yes. Your combat level is determined by your highest offensive style. If your Melee potential (Attack + Strength) is higher than your Magic or Ranged potential, leveling Magic or Ranged won’t increase your combat level until they surpass your Melee stats.
Does leveling up Prayer increase my combat level?
Yes, Prayer contributes to your base combat calculation. Every two levels gained in Prayer will add 0.25 to your overall combat level, which is why some specialized PvP builds keep their Prayer level low.
