If you’re a RuneScape player, understanding your Old School RuneScape (OSRS) combat level is essential for everything from PvP matchups to questing and minigames. Your combat level determines who you can attack in the Wilderness, which bosses you’re ready for, and how your character is progressing in strength and skills.
To save you from complicated math and in-game guesswork, our OSRS Combat Level Calculator allows you to instantly calculate your exact combat level based on your combat stats. In this complete guide, we’ll show you how to use the tool, break down what each input means, and offer tips to get the most accurate results.
OSRS Combat Level Calculator
🎮 What Is the OSRS Combat Level?
Your combat level in Old School RuneScape (OSRS) is a numerical representation of your combat capabilities. It ranges from 3 to 126 for non-member accounts and includes contributions from several different skills:
- Attack
- Strength
- Defence
- Hitpoints
- Ranged
- Magic
- Prayer
It’s a combination of base stats and offensive stats (melee, ranged, or magic), and the highest offensive skill determines your dominant combat style.
⚔️ OSRS Combat Level Formula
The actual combat level formula used by this calculator is the same one used by the game itself:
Base Combat Level = 0.25 × (Defence + Hitpoints + (Prayer ÷ 2))
Melee Combat = 0.325 × (Attack + Strength)
Ranged Combat = 0.325 × (Ranged × 1.5)
Magic Combat = 0.325 × (Magic × 1.5)
Combat Level = Base + Highest of (Melee, Ranged, Magic)
This formula ensures that the skill set you train most will reflect in your combat level.

🧪 Example: Calculating a Mid-Level Melee Build
Let’s say your character has the following stats:
- Attack: 70
- Strength: 70
- Defence: 65
- Hitpoints: 70
- Ranged: 60
- Magic: 55
- Prayer: 52
Calculation Breakdown:
- Base:
0.25 * (65 + 70 + (52 ÷ 2)) = 0.25 * (65 + 70 + 26) = 0.25 * 161 = 40.25 - Melee:
0.325 * (70 + 70) = 0.325 * 140 = 45.5 - Ranged:
0.325 * (60 * 1.5) = 0.325 * 90 = 29.25 - Magic:
0.325 * (55 * 1.5) = 0.325 * 82.5 = 26.81
Final Combat Level: 40.25 + max(45.5, 29.25, 26.81) = 40.25 + 45.5 = 85.75
✅ This character has a combat level of 85.75.
