Osrs Combat Level Calculator

Calculate Your Combat Level

What is an OSRS Combat Level?

In Old School RuneScape (OSRS), the Combat Level is a number that represents a character’s overall power in combat. It’s a key indicator used to quickly assess another player’s strength and is fundamental to many aspects of the game, especially Player vs. Player (PvP) content. This osrs combat level calculator provides an instant and accurate way to determine your level based on your character’s skills. It is not just a simple sum of your levels; it is derived from a specific formula that weighs different skills differently.

Understanding your combat level is crucial for building a specific type of account, such as a “pure” for PvP, where keeping the combat level within a certain bracket is essential. Many players use a calculator like this one to plan their training, deciding which skills to level up to optimize their character for their goals without unintentionally raising their combat level too high.

OSRS Combat Level Formula and Explanation

The combat level calculation in OSRS is not immediately obvious. It combines your defensive stats (Defence, Hitpoints, Prayer) with your highest offensive stat (Melee, Ranged, or Magic). Our osrs combat level calculator automates this for you. The formula is as follows:

Combat Level = Base Level + Highest Combat Modifier

Where:

• Base Level = 0.25 * (Defence Level + Hitpoints Level + floor(Prayer Level / 2))
• Melee Modifier = 0.325 * (Attack Level + Strength Level)
• Ranged Modifier = 0.325 * (floor(Ranged Level * 1.5))
• Magic Modifier = 0.325 * (floor(Magic Level * 1.5))

The game calculates these values, adds the Base Level to the highest of the three combat modifiers, and then truncates (floors) the result to get your final, whole-number combat level. For more details on game mechanics, you could check out the official OSRS Wiki.

Combat Level Formula Variables

Variable	Meaning	Unit	Typical Range
Attack	Your accuracy in melee combat.	Level	1 – 99
Strength	Your maximum damage in melee combat.	Level	1 – 99
Defence	Your ability to resist damage from all combat styles.	Level	1 – 99
Hitpoints	Your life points; determines how much damage you can take.	Level	1 – 99 (starts at 10)
Ranged	Your accuracy and damage with ranged weapons.	Level	1 – 99
Magic	Your accuracy and damage with magical spells.	Level	1 – 99
Prayer	Your ability to use prayers for boosts and protection. Contributes to combat level at half the rate of Defence/HP.	Level	1 – 99

Practical Examples

Example 1: A Melee-Based “Pure” Account

A common PvP build is a “1 Defence Pure,” which maximizes offensive power while keeping the combat level low by not training Defence. Let’s calculate its level.

• Inputs: Attack: 60, Strength: 85, Defence: 1, Hitpoints: 80, Ranged: 1, Magic: 1, Prayer: 13
• Calculation:
  • Base Level = 0.25 * (1 + 80 + floor(13 / 2)) = 0.25 * (81 + 6) = 21.75
  • Melee Modifier = 0.325 * (60 + 85) = 47.125
  • Ranged & Magic Modifiers are negligible.
  • Total = 21.75 + 47.125 = 68.875
• Result: Combat Level 68

Example 2: A High-Level Main Account

A main account typically has high, balanced stats. Let’s see how Magic can become the dominant combat style.

• Inputs: Attack: 75, Strength: 75, Defence: 75, Hitpoints: 90, Ranged: 80, Magic: 94, Prayer: 70
• Calculation:
  • Base Level = 0.25 * (75 + 90 + floor(70 / 2)) = 0.25 * (165 + 35) = 50
  • Melee Modifier = 0.325 * (75 + 75) = 48.75
  • Ranged Modifier = 0.325 * floor(80 * 1.5) = 0.325 * 120 = 39
  • Magic Modifier = 0.325 * floor(94 * 1.5) = 0.325 * 141 = 45.825
  • The Melee Modifier is the highest. Total = 50 + 48.75 = 98.75
• Result: Combat Level 98 (Note: in this case, melee is still higher. If attack/strength were lower, magic might take over). To learn more about skilling, you can view our Skilling Guide.

How to Use This OSRS Combat Level Calculator

Using this tool is straightforward. Follow these simple steps to get an accurate calculation in seconds.

1. Enter Your Levels: Type your current skill levels for Attack, Strength, Defence, Hitpoints, Ranged, Magic, and Prayer into their respective input fields. The calculator defaults to level 1 (or 10 for Hitpoints) but updates instantly as you type.
2. View the Result: The main display shows your final, rounded-down combat level. Below it, you can see the exact fractional value before rounding.
3. Analyze the Modifiers: The “Intermediate Results” section shows you the values for your Base Level and each of the three combat style modifiers. This is useful for seeing which style (Melee, Ranged, or Magic) is currently contributing to your combat level.
4. Reset if Needed: Click the “Reset” button at any time to clear all fields and return them to their default values.

Key Factors That Affect OSRS Combat Level

Several factors influence your combat level, and understanding them is key to strategic account building.

• Defence and Hitpoints: These two skills will ALWAYS increase your combat level. Every 4 levels combined (e.g., 2 Defence and 2 Hitpoints) will add one full point to your base combat calculation.
• Prayer: Prayer provides a slower increase than Defence and Hitpoints. It takes 8 Prayer levels to have the same impact as 4 Defence/Hitpoints levels. This makes it a more “efficient” stat for some PvP builds.
• The Highest Offensive Style: Only your strongest combat style—Melee, Ranged, or Magic—is used in the final calculation. This is why you can train Ranged and Magic to high levels on a melee-based account without gaining combat levels, as long as their modifiers don’t surpass your melee modifier. Check our DPS Calculator to compare styles.
• Attack and Strength Parity: For melee, Attack and Strength levels have an equal weighting. A combination of 50 Attack and 50 Strength gives the same combat modifier as 1 Attack and 99 Strength.
• Ranged and Magic Scaling: Ranged and Magic levels are multiplied by 1.5 in their formulas, giving them a higher impact per level than Attack or Strength individually.
• Rounding Down: The game always rounds the final combat level calculation down to the nearest whole number. A combat level of 120.99 is still just Combat Level 120. This gives you a small buffer to gain experience without levelling up.

Frequently Asked Questions (FAQ)

What is the max combat level in OSRS?

The maximum combat level in Old School RuneScape is 126. This is achieved with 99 Attack, 99 Strength, 99 Defence, 99 Hitpoints, 99 Ranged, 99 Magic, and 99 Prayer.

Does Slayer affect combat level?

No, the Slayer skill does not directly contribute to the combat level formula. However, training Slayer almost always involves gaining experience in combat skills, which in turn will raise your combat level.

Why does this calculator show a decimal result?

The true combat level is a fractional number. The game simply hides the decimal part and shows the floored (rounded down) integer. Our osrs combat level calculator shows both the final level and the exact value so you can see how close you are to the next level.

How can I plan a PvP account with this calculator?

Enter your target stats for a specific PvP bracket (e.g., level 50 wilderness). You can then experiment by increasing certain levels to see what you can train without “leveling out” of your desired combat bracket. Planning your Quest Rewards is also crucial.

Why is my combat level not changing when I level up Ranged or Magic?

This happens when your Melee modifier is significantly higher than your Ranged and Magic modifiers. Since only the highest of the three is used, you can increase the other two until one of them surpasses the current highest one.

Are there any “hidden” levels that affect combat?

No, only the seven skills listed in the calculator (Attack, Strength, Defence, Hitpoints, Ranged, Magic, Prayer) have any effect on your combat level.

Why is Hitpoints level 10 the default?

All new accounts in Old School RuneScape start with 10 Hitpoints, while all other combat stats start at level 1. Our calculator reflects this starting condition.

Can I lower my combat level?

No, it is not possible to lower any of your skill levels or your combat level in Old School RuneScape. All progress is permanent, which makes planning with a calculator like this very important.
