What is the OSRS Combat Calculator?
An osrs combat calculator osrs is a specialized tool designed for players of the popular MMORPG, Old School RuneScape. Its primary function is to calculate a player’s combat level based on their specific skill stats. The combat level is a crucial metric in OSRS, as it provides a general indicator of a player’s strength in battle and is used for matchmaking in PvP (Player vs. Player) activities like the Wilderness and Duel Arena.
This calculator is essential for anyone looking to create a specialized account build, such as a “pure” (an account that focuses on high offensive stats while keeping defensive stats low to maintain a low combat level). By using an OSRS combat calculator, players can plan their training regimen precisely, ensuring they level up the right skills without accidentally increasing their combat level beyond their desired target. For anyone serious about their account’s progression, using an accurate OSRS combat level tool is a must.
OSRS Combat Calculator Formula and Explanation
The combat level in Old School RuneScape is not a simple average of your skills. It’s determined by a specific formula that heavily weights your offensive and defensive capabilities. Our osrs combat calculator osrs uses this exact formula for perfect accuracy.
The core formula is:
Combat Level = Base Level + Highest Offensive Contribution
Where the components are calculated as follows:
- Base Level = 0.25 * (Defence Level + Hitpoints Level + floor(Prayer Level / 2))
- Melee Contribution = 0.325 * (Attack Level + Strength Level)
- Ranged Contribution = 0.325 * (floor(Ranged Level * 1.5))
- Magic Contribution = 0.325 * (floor(Magic Level * 1.5))
The game calculates these three offensive contributions and only uses the highest of the three to add to your base level. This is why a player can have 99 Ranged and 1 Attack/Strength without their melee stats affecting their combat level.
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Defence Level | Your character’s Defence skill level. | Level | 1 – 99 |
| Hitpoints Level | Your character’s Hitpoints skill level. | Level | 10 – 99 |
| Prayer Level | Your character’s Prayer skill level. Affects combat by half its value. | Level | 1 – 99 |
| Attack/Strength | Your melee offensive skills. | Level | 1 – 99 |
| Ranged | Your ranged offensive skill. | Level | 1 – 99 |
| Magic | Your magic offensive skill. | Level | 1 – 99 |
Practical Examples
Example 1: A Balanced Main Account
A player is training a well-rounded account for high-level bossing.
- Inputs: Attack: 90, Strength: 95, Defence: 90, Hitpoints: 99, Ranged: 85, Magic: 85, Prayer: 77
- Calculation:
- Base Level = 0.25 * (90 + 99 + floor(77/2)) = 0.25 * (90 + 99 + 38) = 56.75
- Melee = 0.325 * (90 + 95) = 60.125
- Ranged = 0.325 * floor(85*1.5) = 41.275
- Magic = 0.325 * floor(85*1.5) = 41.275
- Result: Combat Level = 56.75 + 60.125 = 116.875, which is Level 116.
Example 2: A 1-Defence Ranged “Pure”
A player building a PVP pure account that uses ranged attacks.
- Inputs: Attack: 60, Strength: 70, Defence: 1, Hitpoints: 75, Ranged: 90, Magic: 1, Prayer: 52
- Calculation:
- Base Level = 0.25 * (1 + 75 + floor(52/2)) = 0.25 * (1 + 75 + 26) = 25.5
- Melee = 0.325 * (60 + 70) = 42.25
- Ranged = 0.325 * floor(90*1.5) = 0.325 * 135 = 43.875
- Magic = 0.325 * floor(1*1.5) = 0.325
- Result: Combat Level = 25.5 + 43.875 (the highest of the three) = 69.375, which is Level 69. Using an OSRS Max Hit Calculator would be the next step for this player.

Key Factors That Affect OSRS Combat Level
Several skills impact your combat level, but they don’t all have the same weight. Understanding these factors is key to mastering account builds.
- Defence and Hitpoints: These are the cornerstones of your Base Level. Every level gained in these skills will always increase your combat level by 0.25 points.
- Prayer: Prayer has a lesser impact than Defence or Hitpoints, increasing your combat level by only 0.125 points per level (since it’s divided by two in the formula). This makes it a very efficient skill for increasing power without dramatically raising combat.
- Your Dominant Offensive Stat: Only your highest combat style (Melee, Ranged, or Magic) actually counts towards your final level. You can raise your Ranged and Magic to 99, but if your Melee stats are higher, they won’t add a single point to your combat level. This is the core principle behind many OSRS Account Builds.
- Attack and Strength (Melee): These two skills are combined, making melee the fastest way to increase your offensive contribution. Each level in Attack or Strength adds 0.325 points to your melee value.
- Ranged and Magic: These skills are calculated independently and are multiplied by 1.5. This means each level provides a significant boost to their respective contribution (0.325 * 1.5 = ~0.4875 points per level).
- Avoiding “Unwanted” Levels: For pures, the most critical factor is avoiding levels in skills that will push their combat level up unnecessarily. For example, a 1-Defence pure must never gain a Defence level. Using tools like this OSRS combat calculator is the best way to prevent mistakes.
Frequently Asked Questions (FAQ)
1. Is this OSRS combat calculator osrs accurate?
Yes. This calculator uses the exact integer-based formula that Old School RuneScape uses internally, including the floor functions (rounding down) where appropriate. It provides a precise calculation of your combat level.
2. What is the max combat level in OSRS?
The maximum combat level in OSRS is 126. This is achieved with 99 Attack, 99 Strength, 99 Defence, 99 Hitpoints, and 99 Prayer. Ranged and Magic levels do not need to be 99 to achieve the max level, as the Melee contribution will be the highest. For more info, check out our OSRS Quest Guides which can help with leveling.
3. Why does my combat level have a decimal point in the calculation?
The game calculates combat levels using fractions (decimal points), but only displays the whole number (integer part). We show the full decimal value so you can see how close you are to the next full combat level, a feature most other calculators don’t offer.
4. Can I lower my combat level?
No, you cannot lower any of your combat stats in Old School RuneScape. This is why careful planning using an osrs combat calculator osrs is so important before you begin training.
5. Why didn’t my combat level go up when I leveled Ranged?
This happens when your Melee or Magic contribution is already higher than your Ranged contribution. Your combat level is only affected by your *highest* offensive style. Your Ranged level can increase, but it won’t impact your combat level until its contribution surpasses the others.
6. How important is Prayer for my combat level?
Prayer is very efficient. Each Prayer level only adds 0.125 to your combat level, while providing access to powerful overhead protection prayers and stat boosts. This is why high Prayer is common on many PVP builds, as explored in our OSRS Prayer Guide.
7. Does Hitpoints level always increase my combat level?
Yes. Every Hitpoints level you gain will increase your combat level by 0.25 points, without exception. It is one of the four “core” combat skills, along with Defence, that always contributes.
8. What’s the lowest possible combat level?
The lowest combat level is 3. This is the level a new account starts with, typically having 1 in all combat stats (except 10 Hitpoints).
