Enter your current skill levels below to find out your exact combat level in Old School RuneScape.
Your Combat Level Results
Melee Combat Potential: 0.325 * (1 + 1) = 0.65
Ranged Combat Potential: 0.325 * (1.5 * 1) = 0.4875
Magic Combat Potential: 0.325 * (1.5 * 1) = 0.4875
Base Combat Contribution: 0.25 * (1 + 10 + floor(1 / 2)) = 2.75
Formula Used: Combat Level = floor(0.25 * (Defence + Hitpoints + floor(Prayer / 2)) + 0.325 * MAX((Attack + Strength), (1.5 * Ranged), (1.5 * Magic)))
This formula calculates your combat level by summing a base contribution (from Defence, Hitpoints, and half of Prayer) with the highest of your three offensive combat potentials (Melee, Ranged, or Magic).
What is an OSRS Combat Level Calculator?
An OSRS Combat Level Calculator is an essential tool for players of Old School RuneScape. It allows you to accurately determine your character’s combat level based on their current skill levels in Attack, Strength, Defence, Hitpoints, Ranged, Magic, and Prayer. Your combat level dictates the strength of monsters you can effectively fight, the Wilderness levels you can enter, and your overall standing in the game’s combat system.
This calculator is crucial for players who want to optimize their character builds, plan their training paths, or simply understand their combat prowess. Whether you’re aiming for a specific combat bracket for Player-vs-Player (PvP) combat, preparing for high-level bossing, or just curious about your progress, an OSRS Combat Level Calculator provides immediate and precise feedback.
Who Should Use an OSRS Combat Level Calculator?
- New Players: To understand how their skill training impacts their combat level.
- Experienced Players: For min-maxing builds, planning for specific PvP combat brackets (e.g., “pures” or “zerkers”), or optimizing for bossing.
- PvP Enthusiasts: To calculate exact combat levels for Wilderness encounters and ensure they are within desired combat ranges.
- Questing Players: To meet combat level requirements for certain quests or to gauge their readiness for combat-heavy challenges.
Common Misconceptions about OSRS Combat Level
One common misconception is that all combat skills contribute equally. In reality, the formula prioritizes your highest offensive skill set (Melee, Ranged, or Magic) and includes a base contribution from Defence, Hitpoints, and Prayer. Another misconception is that Prayer level has a massive impact; it only contributes half its level to the base calculation, making its direct impact on combat level relatively minor compared to other skills.
OSRS Combat Level Calculator Formula and Mathematical Explanation
The combat level in Old School RuneScape is calculated using a specific formula that combines your combat-related skill levels. Understanding this formula is key to effectively planning your character’s progression.
Step-by-Step Derivation of the OSRS Combat Level Formula:
- Calculate Base Combat Contribution: This part of the formula accounts for your defensive and foundational combat stats. It’s derived from your Defence, Hitpoints, and Prayer levels. Specifically, it’s
0.25 * (Defence Level + Hitpoints Level + floor(Prayer Level / 2)). Thefloor()function ensures that any fractional part of Prayer’s contribution is rounded down. - Calculate Melee Combat Potential: This represents your potential combat level if you primarily use Melee. It’s calculated as
0.325 * (Attack Level + Strength Level). - Calculate Ranged Combat Potential: This represents your potential combat level if you primarily use Ranged. It’s calculated as
0.325 * (1.5 * Ranged Level). The 1.5 multiplier for Ranged (and Magic) effectively makes these skills contribute more per level than Attack or Strength individually, as they are single skills representing an entire combat style. - Calculate Magic Combat Potential: Similar to Ranged, this is your potential combat level if you primarily use Magic. It’s calculated as
0.325 * (1.5 * Magic Level). - Determine Highest Offensive Potential: The game takes the maximum value among your Melee Combat Potential, Ranged Combat Potential, and Magic Combat Potential. This means your combat level is primarily driven by your strongest offensive style.
MAX(Melee Potential, Ranged Potential, Magic Potential). - Final Combat Level Calculation: Your final combat level is the sum of your Base Combat Contribution and your Highest Offensive Potential, rounded down to the nearest whole number using the
floor()function.
Combat Level = floor(Base Combat Contribution + Highest Offensive Potential)
This formula ensures that a player’s combat level reflects their overall combat capability, taking into account both defensive resilience and offensive power in their strongest style.

Practical Examples (Real-World Use Cases)
Let’s look at a couple of examples to illustrate how the OSRS Combat Level Calculator works and what the results mean.
Example 1: A Balanced Melee Account
Imagine a player with the following skill levels:
- Attack: 70
- Strength: 70
- Defence: 70
- Hitpoints: 70
- Ranged: 1
- Magic: 1
- Prayer: 43
Using the OSRS Combat Level Calculator:
- Base Combat Contribution:
0.25 * (70 (Defence) + 70 (Hitpoints) + floor(43 (Prayer) / 2))
= 0.25 * (70 + 70 + 21) = 0.25 * 161 = 40.25 - Melee Combat Potential:
0.325 * (70 (Attack) + 70 (Strength))
= 0.325 * 140 = 45.5 - Ranged Combat Potential:
0.325 * (1.5 * 1 (Ranged)) = 0.4875 - Magic Combat Potential:
0.325 * (1.5 * 1 (Magic)) = 0.4875 - Highest Offensive Potential:
MAX(45.5, 0.4875, 0.4875) = 45.5 - Final Combat Level:
floor(40.25 + 45.5) = floor(85.75) = 85
This player would have a combat level of 85. This is a solid combat level for many mid-to-high level activities, indicating a well-rounded melee character.
Example 2: A Ranged Pure Account
Consider a “ranged pure” account, focused on Ranged combat with minimal Defence:
- Attack: 1
- Strength: 1
- Defence: 1
- Hitpoints: 40
- Ranged: 80
- Magic: 1
- Prayer: 1
Using the OSRS Combat Level Calculator:
- Base Combat Contribution:
0.25 * (1 (Defence) + 40 (Hitpoints) + floor(1 (Prayer) / 2))
= 0.25 * (1 + 40 + 0) = 0.25 * 41 = 10.25 - Melee Combat Potential:
0.325 * (1 (Attack) + 1 (Strength)) = 0.65 - Ranged Combat Potential:
0.325 * (1.5 * 80 (Ranged))
= 0.325 * 120 = 39 - Magic Combat Potential:
0.325 * (1.5 * 1 (Magic)) = 0.4875 - Highest Offensive Potential:
MAX(0.65, 39, 0.4875) = 39 - Final Combat Level:
floor(10.25 + 39) = floor(49.25) = 49
This ranged pure would have a combat level of 49. This low combat level for a high Ranged skill makes them very effective in specific PvP brackets, allowing them to fight lower-level opponents with a significant offensive advantage.
How to Use This OSRS Combat Level Calculator
Our OSRS Combat Level Calculator is designed for ease of use, providing instant results as you input your skill levels. Follow these simple steps to get your combat level:

How to Read Results and Decision-Making Guidance
The primary result, your Combat Level, is your overall combat prowess. The intermediate values are crucial for understanding your build:
- Highest Offensive Potential: This value indicates which combat style (Melee, Ranged, or Magic) is currently contributing the most to your combat level. If you’re training a specific style, this should align with your highest skill.
- Base Combat Contribution: This shows the impact of your Defence, Hitpoints, and Prayer. A higher value here means you’re more resilient or have invested more in these foundational skills.
Use this information to make informed decisions about your training. For example, if you’re trying to stay in a low combat bracket for PvP, you might keep your Defence and Prayer levels low while maximizing one offensive skill. If you’re aiming for high-level bossing, a balanced approach with high levels in all combat stats is usually preferred. The OSRS Combat Level Calculator is your guide to strategic skill training.
Key Factors That Affect OSRS Combat Level Results
The OSRS Combat Level Calculator relies on several key factors, each playing a distinct role in determining your final combat level. Understanding these factors is crucial for effective character planning and optimization.
- Offensive Skill Levels (Attack, Strength, Ranged, Magic): These are the primary drivers of your combat level. The formula takes the highest potential from your Melee (Attack + Strength), Ranged (1.5 * Ranged), or Magic (1.5 * Magic) skills. This means focusing on one offensive style will generally increase your combat level faster in that style’s direction.
- Defence Level: Your Defence level directly contributes to the “base” portion of your combat level. Higher Defence makes your character more resilient but also increases your combat level, which can be a consideration for specific PvP builds.
- Hitpoints Level: Similar to Defence, Hitpoints contributes to the base combat level. Since Hitpoints naturally increases as you gain combat experience, it’s a consistent factor in combat level progression.
- Prayer Level: While Prayer is a combat skill, its contribution to the combat level is halved (
floor(Prayer / 2)). This means Prayer has a less significant impact on your combat level compared to other skills, making it a popular choice for “pures” who want to gain utility without drastically increasing their combat level. - Skill Balance: The balance between your offensive skills is critical. If your Ranged level is significantly higher than your combined Attack and Strength, your combat level will be primarily Ranged-based. The OSRS Combat Level Calculator helps visualize this balance.
- Training Strategy: Your chosen training strategy directly impacts your combat level. A player training only Ranged will have a different combat level progression than someone training all three offensive styles equally. This calculator helps predict the outcome of various training paths.
Each of these factors interacts within the OSRS Combat Level Calculator to produce your final combat level, making it a dynamic and strategic aspect of Old School RuneScape gameplay.
Frequently Asked Questions (FAQ) about the OSRS Combat Level Calculator
- Q: What is the maximum combat level in OSRS?
- A: The maximum combat level in Old School RuneScape is 126. This is achieved by having 99 in Attack, Strength, Defence, Hitpoints, Ranged, Magic, and Prayer.
- Q: Does Prayer level affect my combat level significantly?
- A: Prayer level contributes to your combat level, but only half its value (rounded down). So, while it does increase your combat level, its impact is less significant compared to other combat skills like Attack, Strength, Ranged, or Magic.
- Q: Why is my combat level not increasing even if I train a combat skill?
- A: Your combat level is determined by your highest offensive potential (Melee, Ranged, or Magic) plus your base contribution. If you’re training a skill that isn’t currently your highest offensive potential, or if the increase is very small, your overall combat level might not immediately go up until you cross a certain threshold.
- Q: What is a “pure” account, and how does the OSRS Combat Level Calculator help them?
- A: A “pure” account is a character built with specific low combat stats (often Defence) to achieve a low combat level while maximizing offensive power in one style. The OSRS Combat Level Calculator is invaluable for pures to precisely manage their combat level and ensure they stay within desired PvP brackets.
- Q: Can I use this calculator to plan future combat levels?
- A: Yes, absolutely! By inputting hypothetical future skill levels, you can see what your combat level will be. This is excellent for planning your training goals and understanding the impact of each skill increase on your overall combat level.
- Q: Why does the calculator use “floor” for some calculations?
- A: The “floor” function (rounding down to the nearest whole number) is part of the official OSRS combat level formula. It ensures that fractional combat level contributions are always rounded down, resulting in a whole number combat level.
- Q: Is this OSRS Combat Level Calculator accurate?
- A: Yes, this calculator uses the exact, official formula for Old School RuneScape combat levels, ensuring 100% accuracy based on your input skill levels.
- Q: What is the minimum Hitpoints level for combat?
- A: All new accounts start with 10 Hitpoints. This is the minimum level required to engage in combat and is factored into the OSRS Combat Level Calculator.
