Combat Level Results
🧮 What Is the RuneScape Combat Level?
Your combat level in RuneScape represents your overall combat strength, combining stats like Attack, Strength, Defence, Hitpoints, Ranged, Magic, and Prayer.
A higher combat level allows you to:
- Equip stronger weapons and armor
- Access higher-tier monsters and PvM zones
- Join PvP zones like the Wilderness with an edge
- Determine who you can attack and be attacked by in PvP
Since the formula varies slightly between OSRS and RS3, the RuneScape Combat Level Calculator helps simplify and automate these calculations.
⚙️ How the RuneScape Combat Level Calculator Works
You simply input your current levels in the following skills:
- Attack
- Strength
- Defence
- Hitpoints (Constitution in RS3)
- Ranged
- Magic
- Prayer
- Summoning (RS3 only)
The calculator then determines your combat level using the official formula for the version of RuneScape you are playing.
✳️ Combat Level Formula (Old School RuneScape – OSRS)
OSRS uses this formula:
pgsqlCopyEditBase = 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)) Combat Level = Base + Highest(Melee, Ranged, Magic) The maximum combat level in OSRS is 126.
✳️ Combat Level Formula (RuneScape 3 – RS3)
RS3 uses the following formula:
pgsqlCopyEditBase = 0.25 × (Defence + Constitution + floor(Prayer / 2) + floor(Summoning / 2)) Melee = 1.3 × (Attack + Strength) Ranged = 1.5 × Ranged Magic = 1.5 × Magic Combat Level = Base + 0.325 × Highest(Melee, Ranged, Magic) The max combat level in RS3 is 138.

🔢 Example Calculation (OSRS)
Suppose your stats are:
- Attack: 70
- Strength: 70
- Defence: 70
- Hitpoints: 70
- Prayer: 52
- Ranged: 85
- Magic: 94
Step 1: Base Calculation
iniCopyEditBase = 0.25 × (70 + 70 + floor(52 / 2)) = 0.25 × (70 + 70 + 26) = 0.25 × 166 = 41.5 Step 2: Combat Style Calculations
- Melee = 0.325 × (70 + 70) = 0.325 × 140 = 45.5
- Ranged = 0.325 × floor(85 × 1.5) = 0.325 × 127 = 41.28
- Magic = 0.325 × floor(94 × 1.5) = 0.325 × 141 = 45.825
Step 3: Final Combat Level
pgsqlCopyEditCombat Level = Base + Highest(Melee, Ranged, Magic) Combat Level = 41.5 + 45.825 = 87.325 → Level 87 🎯 Why Use a RuneScape Combat Level Calculator?

💡 Expert Tips
- Prayer and Summoning (in RS3) only give fractional bonuses, so they’re less effective at increasing combat level than other skills.
- To raise your combat level faster, focus on the highest damage-dealing skill path (Melee, Ranged, or Magic).
- For pure builds, keep Defence low and maximize offensive stats to stay at a low combat level with high damage.
- PvP worlds use combat level brackets, so optimizing your level is critical.
