Using the OSRS Combat Calculator
The osrs combat calculator is an essential tool for Old School RuneScape players who want to optimize their character builds. Whether you are building a pure, a main, or a specialized PvP build, knowing how your stats influence your combat level is vital for efficiency and matchmaking.
To use this calculator, simply enter your current or target levels for each of the seven combat skills. The calculator will immediately determine your total combat level and show you which combat style (Melee, Ranged, or Magic) is currently dictating your level.
- Attack & Strength
- These levels contribute to your Melee combat calculation. In OSRS, they are weighted equally.
- Defence & Hitpoints
- These are "base" stats. Every level in Defence or Hitpoints contributes 0.25 towards your total combat level.
- Ranged & Magic
- These are calculated separately. Your combat level only uses the highest of either your Melee, Ranged, or Magic contribution.
How the OSRS Combat Formula Works
The OSRS combat formula is unique because it separates "Base" stats from "Offensive" stats. You have one base combat score, and then a secondary score based on your highest offensive style. The formula used by our osrs combat calculator is:
Combat Level = Base + Max(Melee, Ranged, Magic)
The components are calculated as follows:
- Base: 0.25 * (Defence + Hitpoints + floor(Prayer / 2))
- Melee: 0.325 * (Attack + Strength)
- Ranged: 0.325 * floor(Ranged * 1.5)
- Magic: 0.325 * floor(Magic * 1.5)
Calculation Example
Example: Let's calculate the combat level for a "Rune Pure" build with the following stats: 60 Attack, 80 Strength, 40 Defence, 75 Hitpoints, 44 Prayer, 1 Ranged, and 1 Magic.
Step-by-step solution:
- Base: 0.25 * (40 + 75 + floor(44 / 2)) = 0.25 * (115 + 22) = 0.25 * 137 = 34.25
- Melee: 0.325 * (60 + 80) = 0.325 * 140 = 45.5
- Ranged: 0.325 * floor(1 * 1.5) = 0.325
- Magic: 0.325 * floor(1 * 1.5) = 0.325
- Comparison: Max(45.5, 0.325, 0.325) = 45.5
- Final Level: 34.25 + 45.5 = 79.75
- OSRS Result: Level 79 (The game always rounds down)
Common OSRS Combat Questions
What is the maximum combat level in OSRS?
The maximum combat level in Old School RuneScape is 126. This is achieved by reaching level 99 in all combat stats: Attack, Strength, Defence, Hitpoints, Prayer, Ranged, and Magic.
Can I increase Magic without leveling up my combat?
Yes, but only if your Magic contribution remains lower than your Melee or Ranged contribution. If you are "Melee-based," you can level Magic up to a certain point (usually 1.5x the sum of your attack and strength) without gaining a single combat level. This is a common tactic for PvP builds.
Does Prayer always increase combat level?
Not every level. Because the formula uses 0.125 * Prayer (0.25 * floor(Prayer/2)), you generally gain a combat level every 8 Prayer levels, assuming you are at the very edge of a level up. Every 2 Prayer levels contributes 0.25 combat points.
