OSRS Combat Level Formula
The OSRS Combat Level (CL) is calculated using a complex weighted average that determines your highest possible attack style potential combined with your defensive and auxiliary skills (Defence, Hitpoints, and Prayer).
CL = floor [ 0.25 * (D + H + floor(P/2)) + 0.325 * max( (A + S), floor(1.5 * R), floor(1.5 * M) ) ]

Variables Explained
Each variable represents a skill level you must input into the calculator:
- A (Attack): Used in the Melee component.
- S (Strength): Used in the Melee component.
- D (Defence): Used in the Defensive base component.
- H (Hitpoints): Used in the Defensive base component.
- R (Ranged): Used in the Ranged component, weighted by 1.5.
- M (Magic): Used in the Magic component, weighted by 1.5.
- P (Prayer): Used in the Defensive base component, weighted by 0.5.
What is the OSRS Combat Level?
The Combat Level is an indicator of a player’s power in battle. It ranges from 3 to 126 and is primarily used to assess the difficulty of fighting NPCs (Non-Player Characters) or other players (in PvP zones). Having a higher combat level generally means higher potential to deal damage and take hits.
The formula’s structure highlights that only your single best attack style (Melee, Ranged, or Magic) contributes to the offensive portion of your level, making it crucial for specialized accounts like “Pure” builds to maximize one style while keeping others low.
Understanding your combat level is essential for questing, bossing, and participating in the Wilderness, where the level difference between players affects who you can attack.
How to Calculate OSRS Combat Level (Example)
Let’s calculate the Combat Level for an account with the following stats: Attack 60, Strength 70, Defence 50, Hitpoints 65, Ranged 1, Magic 1, Prayer 40.
- Calculate Defensive Base: $$Base = 0.25 \times (50 (D) + 65 (H) + \lfloor 40 (P) / 2 \rfloor)$$ $$Base = 0.25 \times (50 + 65 + 20) = 0.25 \times 135 = 33.75$$
- Calculate Offensive Style Bases: $$Melee = 0.325 \times (60 (A) + 70 (S)) = 0.325 \times 130 = 42.25$$ $$Ranged = 0.325 \times \lfloor 1.5 \times 1 \rfloor = 0.325 \times 1 = 0.325$$ $$Magic = 0.325 \times \lfloor 1.5 \times 1 \rfloor = 0.325 \times 1 = 0.325$$
- Find Max Offensive Base: $$MaxOffensive = \max(42.25, 0.325, 0.325) = 42.25$$
- Calculate Final Combat Level: $$CL = Base + MaxOffensive = 33.75 + 42.25 = 76$$ The final combat level is **76**.
Frequently Asked Questions (FAQ)
- Q: Does the Summoning skill affect my OSRS Combat Level?
- A: No. Summoning is a skill from RuneScape 3 (RS3) and is not present in Old School RuneScape (OSRS). The OSRS combat level formula only considers Attack, Strength, Defence, Hitpoints, Ranged, Magic, and Prayer.
- Q: What is the maximum Combat Level in OSRS?
- A: The maximum possible Combat Level in Old School RuneScape is **126**, achieved when all relevant skills (Attack, Strength, Defence, Hitpoints, Ranged, Magic, and Prayer) are level 99.
- Q: Why is my Combat Level based on my highest attack style?
- A: The formula is designed to ensure that players cannot gain a high combat level without specializing. Since a player can only attack using one style at a time, the formula takes the highest potential damage output (Melee, Ranged, or Magic) and weights it heavily.
- Q: What is a ‘Pure’ account build?
- A: A ‘Pure’ account typically maximizes one offensive skill (e.g., Strength, Ranged, or Magic) while keeping Defence at level 1 to maintain a lower overall Combat Level, allowing them to fight lower-level opponents in Player-vs-Player (PvP) combat with a damage advantage.
