Official Combat Formula Logic

Combat level in Old School RuneScape is calculated using this logic:

Base = 0.25 × (Defence + Hitpoints + floor(Prayer / 2))

Then highest of:

• Melee = 0.325 × (Attack + Strength)
• Ranged = 0.325 × (floor(Ranged × 1.5))
• Magic = 0.325 × (floor(Magic × 1.5))

Final Combat Level = Base + Highest Combat Style

The result is rounded down to the nearest whole number.

Let’s say your stats are:

• Attack: 75
• Strength: 75
• Defence: 70
• Hitpoints: 75
• Prayer: 70
• Magic: 99
• Ranged: 90

The calculator will compute your base value and determine whether Magic or Melee contributes more. It then provides your final combat level exactly as shown in-game.

This helps PvP players determine wilderness attack ranges and optimize builds.

Why Combat Level Matters in OSRS

PvP Wilderness Brackets

In PvP zones, you can attack players within a certain combat level range. Accurate calculation prevents misjudging attackable targets.

Efficient Build Planning

Many players create specific builds such as:

• 1 Defence Pure
• Zerker (45 Defence)
• Piety Build
• Maxed Main

Using this calculator helps avoid unwanted combat level increases.

Bossing & PvM

Higher combat levels improve survivability and access to certain bosses.
