What is a RuneScape Combat Calculator?
A runescape calculator for combat level is a specialized tool that determines a player’s overall combat power based on their specific skill levels. In Old School RuneScape (OSRS), your combat level is a single number that gives other players a quick idea of your strength in a fight. It’s not just a simple average; it’s calculated using a specific, weighted formula that prioritizes certain skills over others.
This tool is essential for players who are planning a specific character build, such as a “pure” account that keeps certain skills low to gain an advantage in specific PvP (Player vs. Player) scenarios. By using a runescape calculator, you can see how leveling up a skill will affect your final combat level before you commit hours of training. This prevents mistakes that could ruin a carefully planned account build.
The OSRS Combat Level Formula
The game uses a precise formula to calculate the combat level, ensuring a balanced system. The formula is a combination of your defensive stats and your strongest offensive style.
The formula is broken down as follows:
- Base Level = 0.25 * (Defence Level + Hitpoints Level + Floor(Prayer Level / 2))
- Melee Level = 0.325 * (Attack Level + Strength Level)
- Ranged Level = 0.325 * (Floor(Ranged Level * 1.5))
- Magic Level = 0.325 * (Floor(Magic Level * 1.5))
Your final combat level is then calculated as: Base Level + MAX(Melee Level, Ranged Level, Magic Level). The result is always rounded down to the nearest whole number.
Formula Variables
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Attack, Strength, Defence, etc. | The player’s current level in that specific skill. | Level | 1 – 99 |
| Base Level | The foundational component of your combat level, derived from defensive skills. | Points | N/A |
| Melee/Ranged/Magic Level | The weighted value of each of the three combat styles. The highest of these is used. | Points | N/A |

Practical Examples
Example 1: A Melee “Pure” Build
A common build is a “1 Defence Pure,” which focuses on maximizing melee damage while keeping the combat level as low as possible.
- Inputs: Attack: 60, Strength: 80, Defence: 1, Hitpoints: 75, Ranged: 1, Magic: 1, Prayer: 1
- Calculation:
- Base = 0.25 * (1 + 75 + 0) = 19
- Melee = 0.325 * (60 + 80) = 45.5
- Ranged = 0.325 * (1) = 0.325
- Magic = 0.325 * (1) = 0.325
- Final Combat Level = 19 + 45.5 = 64.5 -> 64
Example 2: A Balanced Main Account
A high-level “main” account will have well-rounded stats across all combat skills.
- Inputs: Attack: 90, Strength: 95, Defence: 90, Hitpoints: 99, Ranged: 85, Magic: 85, Prayer: 77
- Calculation:
- Base = 0.25 * (90 + 99 + 38) = 56.75
- Melee = 0.325 * (90 + 95) = 60.125
- Ranged = 0.325 * (Floor(85 * 1.5)) = 0.325 * 127 = 41.275
- Magic = 0.325 * (Floor(85 * 1.5)) = 0.325 * 127 = 41.275
- Final Combat Level = 56.75 + 60.125 = 116.875 -> 116

- Analyze the Chart: The bar chart provides a visual representation of which combat style (Melee, Ranged, or Magic) is the dominant factor in your calculation.
Key Factors That Affect RuneScape Combat Level
- Defence and Hitpoints: These are the cornerstones of your combat level. Every level in these skills will increase your combat level.
- Prayer: Prayer has a smaller but still significant impact. You gain a “combat point” for every two prayer levels, making it a slow but steady contributor.
- Dominant Combat Style: Only your highest combat style (Melee, Ranged, or Magic) is added to your base level. This is the core principle that allows “pure” accounts to exist. For example, a melee-based character can train Ranged and Magic to a certain point without it affecting their combat level at all, as long as the Melee value remains the highest. Check out our {related_keywords} guide for more details.
- Attack and Strength (Melee): These two skills are combined for the melee calculation, meaning they are equally important for melee-based accounts.
- Ranged and Magic Scaling: The formula multiplies your Ranged and Magic levels by 1.5 before the final weight is applied. This means that, level for level, Ranged and Magic have a slightly greater impact on their respective offensive calculations than a single melee skill does.
- Rounding: The game always rounds down at various stages of the calculation, which can sometimes lead to gaining a level without your combat level increasing immediately.
Understanding these factors is key to mastering account builds. Our {related_keywords} page offers more insight.
Frequently Asked Questions (FAQ)
1. What is the maximum combat level in OSRS?
The maximum combat level in Old School RuneScape is 126. This is achieved with 99 Attack, Strength, Defence, Hitpoints, Ranged, Magic, and Prayer.
2. Is this runescape calculator for OSRS or RS3?
This calculator uses the formula for Old School RuneScape (OSRS). The combat calculation in RuneScape 3 (RS3) is different and includes the Summoning skill.
3. Why didn’t my combat level go up when I leveled a skill?
This happens for two reasons. First, the formula involves fractions and rounding down. You may need another level for the total to tick over to the next whole number. Second, if you train a non-dominant combat style (e.g., training Ranged when your Melee value is much higher), it won’t affect your combat level until it surpasses the dominant style’s value.
4. How does Prayer affect my combat level?
Prayer levels contribute to your base defensive level. Specifically, your Prayer level is halved, rounded down, and then added to your Defence and Hitpoints levels before the final 0.25 multiplier is applied. Every 2 prayer levels effectively add 0.25 to your base calculation.
5. Can I lower my combat level?
No, you cannot lower skill levels in RuneScape. This is why using a runescape calculator for planning is so critical. Any mistake in training is permanent.
6. Why do Ranged and Magic seem to add more combat levels?
The formula multiplies the Ranged and Magic levels by 1.5. This means that a Ranged level of 66 has a similar offensive weight as having 99 in both Attack and Strength (66 * 1.5 = 99). This makes them more “combat-heavy” per level compared to melee skills individually.
7. How accurate is this runescape calculator?
This calculator is highly accurate as it implements the official OSRS combat level formula precisely, including all fractional multipliers and rounding rules.
8. Do non-combat skills affect my combat level?
No, skills like Mining, Fishing, or Agility have no effect on your combat level. For training those, you might want a different tool like a {related_keywords}.
