You spend a minute in Old School RuneScape (OSRS) and you know the importance of your combat level. Regardless of whether you are a skiller and do not need to go through the levels to reach the unnecessary level, or a PvP player and optimize your build, it is essential to understand how your statistics influence your general level of combat. The Combat Calculator OSRS is an easy-to-use, but rather efficient, tool that makes you understand how your stats work out, and you will no longer feel confused or make a wrong calculation.
Now it is time to immerse into the essence of what this calculator is, how it functions and why every RuneScape player ought to use this calculator to optimize his or her build.

What Is the Combat Calculator OSRS?
The OSRS Combat Calculator is an online application that allows you to compute the precise combat level and depends on your core statistics Attack, Strength, Defence, Hitpoints, Ranged, Magic, and Prayer.
Put simply, your level of combat is the degree of power of your character in fighting. It is what other players would see when they right-click you in-game. However, the twist is as follows: OSRS does not simply sum total of your statistics and consider the task done – the calculation which determines your combat level is quite complicated.
This is broken down by the calculator. You do not need to do the calculations manually (which is practically nobody would like to do it) and instead, you simply input your then-current levels and have the calculator automatically compute your combat level.
⚙️ How the Combat Level Is Calculated in OSRS
To understand what the calculator does, it’s helpful to look at the formula it’s based on.
Your combat level is calculated from these components:
-
Attack and Strength (for melee)
-
Ranged
-
Magic
-
Defence
-
Hitpoints
-
Prayer
Depending on which combat type is highest, the formula adjusts to determine your dominant combat style — Melee, Ranged, or Magic.
Here’s how it roughly works:
Looks confusing? Don’t worry — the Combat Calculator OSRS does all of this for you behind the scenes.
Core Stats You’ll Need
On opening the calculator, you will see there are a few fields required with a question mark [?]. Required field.” These are your baseline figures, and by keying them in, you will have the right results.
Here’s what each one means:
- Attack Level: This defines how good you are at your weapons of melee.
- Strength Level: This determines the level of damage that you can inflict with melee attacks.
- Defence Level: Lessens the damages, which you incur due to the attacks of the enemies.
- Hitpoints Level: The amount of health that you have.
- Prayer Level: Gives combat bonuses and prayer of protection.
- Ranged Level: This is the level that determines how precise and damaging your usage of the bows or crossbows is.
- Magic Level: Determines your power to cast spells and inflict damage based on magic.
Optional Stats That Don’t Affect Combat Level
The calculator also includes optional fields, like:
-
🪓 Slayer
-
🌀 Agility
-
🧙♀️ Summoning (only relevant in RS3, not OSRS)
-
📘 Extra XP Fields (Attack XP, Strength XP, etc.)
These statistics do not directly affect your level of combat in OSRS, but you can keep the records on them to monitor personal improvement or strategize your experience. It is particularly useful when you have a number of goals that are related to skills.
How to Use the Combat Calculator OSRS (Step-by-Step)
Let’s walk through how you can use this calculator, just like the one shown in the screenshot.
Step 1: Open the Calculator
Head to a trusted OSRS Combat Level Calculator website. You’ll usually see tabs labeled Core Stats, Combat Types, and Optional Stats.
Step 2: Enter Your Core Stats
Start by filling in your essential levels:
-
Attack: e.g., 75
-
Strength: e.g., 80
-
Defence: e.g., 70
-
Hitpoints: e.g., 75
-
Prayer: e.g., 70
Each field is required for the calculator to function properly.
Step 3: Fill in Combat Type Stats
If you’re using Ranged or Magic primarily, enter those too:
-
Ranged: e.g., 85
-
Magic: e.g., 90
These help determine your dominant combat type.
Step 4: (Optional) Add Other Stats
If you want to log Slayer, Agility, or XP fields, go ahead — but it’s not necessary for the combat level calculation.
Step 5: Click “⚔️ Calculate Combat Level”
Once you’ve entered everything, click the big purple-blue button at the bottom — Calculate Combat Level.
The result appears instantly, showing your Combat Level and often a breakdown of how each stat contributes to it.
Example Calculation
Let’s say your stats look like this:
-
Attack: 75
-
Strength: 80
-
Defence: 70
-
Hitpoints: 75
-
Prayer: 70
-
Ranged: 85
-
Magic: 90
The calculator instantly determines that your Magic is your dominant style. Based on the formula, your combat level will fall somewhere around 112–115, depending on the exact scaling of your prayer bonus.
This means you’ll appear as “Level 113” in-game — which is quite a solid build for hybrid combat!
Why Use the Combat Calculator OSRS?
You might wonder, “Can’t I just see my combat level in-game?”
Yes — but this calculator does much more. Here’s why it’s useful:
-
Perfect for Build Planning
Before training a skill, check how it will affect your overall combat level.
For example, if you’re building a 1 Defence pure or 75 Attack hybrid, the calculator ensures you don’t accidentally gain an extra combat level you don’t want. -
Ideal for PvP Players
PvP builds require precision. One wrong level in Defence or Prayer can push you into a higher combat bracket, ruining your efficiency. -
Helpful for Ironmen and Skillers
Skillers who want to avoid levelling combat can use the calculator to see how certain quests or XP rewards might affect their stats. -
Instant and Accurate
It saves you from manually applying the complex RuneScape formula. One click and you get the exact number. -
Supports Both OSRS and RS3 Versions
Many calculators allow toggling between OSRS and RS3 formulas, making it versatile for both player bases.
Tips for Using the OSRS Combat Calculator Effectively
Here are a few smart ways to make the most out of it:
-
✅ Experiment with Builds:
Try different combinations of stats to see how they impact your combat level. This is especially useful if you’re planning a hybrid build. -
⚖️ Balance Prayer Wisely:
Prayer levels add a lot to your combat level. Before training Prayer, check how much it will increase your overall level. -
🏹 Test Ranged and Magic Builds:
If you’re a pure or zerker, switching to Ranged or Magic focus might optimize your efficiency. -
🔍 Use It Before Quests:
Some quests give Defence or Attack XP. Input those potential increases to see if they’ll level you up.
