Combat Level Breakdown
What is the RS Combat Level Calculator?
An RS Combat Level Calculator is a specialized tool used by players of the popular MMORPG Old School RuneScape (OSRS). It determines a player’s combat level, a key indicator of their overall strength in battle. This number is prominently displayed next to a player’s name and helps others quickly assess their power. Unlike a simple sum of levels, the combat level is calculated using a specific, weighted formula that considers seven different skills. This rs combat level calculator helps players plan their character progression, create specialized account builds (like “pures”), and understand how training certain skills will impact their overall level.
The RuneScape Combat Level Formula and Explanation
The combat level in Old School RuneScape is not a simple addition of your skills. It’s derived from a formula that gives different weights to defensive, offensive, and supplementary combat skills. The game calculates your potential combat level based on Melee, Ranged, and Magic, and then uses the highest of the three to determine your final level. The core formula can be broken down into two main parts:
- Base Level: A foundational value derived from your defensive stats.
- Offensive Modifier: The strongest of your three combat styles (Melee, Ranged, or Magic).
The precise formula is: Combat Level = (Base Level) + (Highest Offensive Modifier)
Variables Table
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Base Level | 0.25 * (Defence + Hitpoints + Floor(Prayer / 2)) |
Level Points | 2.5 – 74.25 |
| Melee Modifier | 0.325 * (Attack + Strength) |
Level Points | 0.65 – 64.35 |
| Ranged Modifier | 0.325 * (Floor(Ranged * 1.5)) |
Level Points | 0.325 – 48.075 |
| Magic Modifier | 0.325 * (Floor(Magic * 1.5)) |
Level Points | 0.325 – 48.075 |

Practical Examples
Example 1: A Melee-Focused Player
Consider a player who focuses on melee combat. Their stats might be:
- Inputs: Attack: 70, Strength: 80, Defence: 60, Hitpoints: 75, Prayer: 45, Ranged: 1, Magic: 1
- Calculation:
- Base Level: 0.25 * (60 + 75 + Floor(45 / 2)) = 0.25 * (135 + 22) = 39.25
- Melee Modifier: 0.325 * (70 + 80) = 0.325 * 150 = 48.75
- Ranged Modifier: 0.325 * (Floor(1 * 1.5)) = 0.325 * 1 = 0.325
- Magic Modifier: 0.325 * (Floor(1 * 1.5)) = 0.325 * 1 = 0.325
- Result: The highest modifier is Melee (48.75). The total combat level is Floor(39.25 + 48.75) = Floor(88) = 88.
Example 2: A Magic-Based “Pure” Account
A “pure” account specializes in one combat style while keeping others low. A magic pure might have:
- Inputs: Attack: 1, Strength: 1, Defence: 1, Hitpoints: 60, Prayer: 52, Ranged: 1, Magic: 85
- Calculation:
- Base Level: 0.25 * (1 + 60 + Floor(52 / 2)) = 0.25 * (61 + 26) = 21.75
- Melee Modifier: 0.325 * (1 + 1) = 0.65
- Ranged Modifier: 0.325 * (Floor(1 * 1.5)) = 0.325
- Magic Modifier: 0.325 * (Floor(85 * 1.5)) = 0.325 * 127 = 41.275
- Result: The highest modifier is Magic (41.275). The total combat level is Floor(21.75 + 41.275) = Floor(63.025) = 63. Understanding these calculations is key to build planning, much like using a Slayer Task Calculator for efficient training.

- Reset if Needed: Click the “Reset” button to return all fields to their default values to start a new calculation.
Key Factors That Affect Combat Level
Several factors influence your combat level, and understanding them is crucial for effective character development.
- Attack and Strength: For melee-based accounts, these two skills provide the most significant increase in combat level. They are weighted heavily in the melee modifier.
- Defence and Hitpoints: These form the core of your “Base Level.” Every level gained in these skills will always increase your combat level, regardless of your primary attack style. They are essential for survivability.
- Prayer: Prayer has a smaller impact than other skills because its level is halved in the formula. However, it still contributes to your base level and is crucial for high-level content.
- Ranged and Magic: These skills have their own modifiers. Because their level is multiplied by 1.5 in the calculation, they provide a faster combat level increase than training Attack or Strength alone, but not as fast as training both together. This is important for players using a Quest Calculator to unlock new spells or gear.
- Combat Style Dominance: Your final level is determined by whichever combat style (Melee, Ranged, or Magic) has the highest offensive modifier. This is why “pure” accounts can have a low combat level but be very powerful in their chosen style.
- Summoning: In Old School RuneScape (OSRS), the Summoning skill does not exist and therefore does not affect your combat level. This is a key difference from RuneScape 3.
Frequently Asked Questions (FAQ)
What is the maximum combat level in OSRS?
The maximum combat level in Old School RuneScape is 126. This is achieved with 99 in Attack, Strength, Defence, Hitpoints, Ranged, Magic, and Prayer.
Why does this calculator show a decimal result sometimes?
The underlying formula produces fractional results. The game of RuneScape always rounds the final number down (a “floor” function) to display a whole number. We show the decimal to help you see how close you are to your next full combat level.
Is this rs combat level calculator for OSRS or RS3?
This calculator uses the formula for Old School RuneScape (OSRS). RuneScape 3 (RS3) uses a different formula and includes the Summoning skill, resulting in a higher maximum combat level (138).
How can I train combat without gaining Hitpoints levels?
Certain methods, like using a cannon for Ranged or casting specific non-damaging spells for Magic (e.g., High-Level Alchemy), grant experience in those skills without granting Hitpoints XP. This is a common tactic for building certain “pure” accounts.
Which skill gives the most combat levels?
Training Attack and Strength together provides the fastest melee-based combat level increase. For ranged and magic, each level has a 1.5x multiplier in the formula, also leading to rapid gains. Defence and Hitpoints provide a steady, guaranteed increase with every level.
Can I lower my combat level?
No, you cannot lower a combat stat once you have leveled it up. Therefore, your combat level can only increase. This is why careful planning with a rs combat level calculator is so important.
Does Slayer level affect combat level?
No, non-combat skills like Slayer, Agility, or Mining have no effect on your combat level calculation. However, training Slayer is a primary method for training combat skills.
Why is Prayer only half its value in the formula?
This is a game balancing decision by the developers. It makes it so that gaining Prayer levels has less of an impact on your combat level compared to Defence or Hitpoints, which is important for Player-vs-Player (PvP) balance.
