How Combat Level is Calculated
Step 1: Calculate Base Level
Base = (Defence + Hitpoints + ⌊Prayer ÷ 2⌋) ÷ 4
- Each level in Defence adds +0.25 combat levels
- Each level in Hitpoints adds +0.25 combat levels
- Every 2 levels in Prayer adds +0.25 combat levels
Step 2: Determine Combat Style
The system calculates three values and uses the highest:
- Melee: (Attack + Strength) × 0.325
- Ranged: ⌊Ranged × 1.5⌋ × 0.325
- Magic: ⌊Magic × 1.5⌋ × 0.325
Step 3: Final Combat Level
Combat Level = ⌊Base + max(Melee, Ranged, Magic)⌋
Maximum Levels:
- Melee-based accounts: Up to level 126
- Ranged/Magic-based accounts: Up to level 109

Level-Up Path Visualization
OSRS Combat Level Calculator: Plan Your Way to 126 Without Wasting XP
You’ve just leveled up your Strength, but your combat level didn’t budge. Sound familiar? You open your stats, stare at the number—82—and wonder: Should I train Ranged instead? How close am I really to 100? The official OSRS combat formula isn't exactly intuitive. That’s why a dedicated OSRS combat calculator that uses the actual 2026 game mechanics is the difference between grinding blind and planning smart.
The tool at HeyCalc does exactly that. It’s a free OSRS combat calculator that lives entirely in your browser. No downloads, no uploads of your stats to some unknown server. You punch in your levels—Attack, Strength, Defence, Hitpoints, Ranged, Magic, Prayer—and it instantly returns your exact combat level. More importantly, it shows you which skill to train next for the fastest possible level-up.
Why Most Combat Calculators Leave You Guessing (And This One Doesn’t)
Most online tools just spit out a number. You get your combat level, but you’re left with the same question: Do I grind Defence or finally work on Magic? This tool solves that with three core features that actually feel like they were built by someone who plays the game.
First, the Skill Contribution Analysis. It’s not just a table of numbers. You get a radar chart that visualizes exactly how much each skill is contributing to your current combat level. See at a glance if you’re a melee-based account, or if your Ranged level is secretly carrying you.
Second, the Detailed Breakdown Table. This is where the official Wiki formula becomes human-readable. You’ll see separate calculations for Melee, Ranged, and Magic. For each one, the tool shows the base level, the combat bonus (that crucial *1.5 for Ranged and Magic), and the total contribution. No more wondering why your level 85 Magic isn’t pushing you higher.
Third, and most useful for active planning: the Level Planner. After you calculate your current level, this tab generates personalized upgrade recommendations. It answers the exact question every mid-game player asks: What’s the single most efficient skill to train right now? Sometimes it’s Attack and Strength together. Sometimes it’s that half-level of Prayer you’ve been ignoring.
How the OSRS Combat Formula Actually Works (2026 Mechanics)
The game uses a two-step process. It’s simpler than it looks, but the weightings are what catch people out.
Step 1: The Base Level Your base is calculated from your defensive stats: Base = (Defence + Hitpoints + ⌊Prayer ÷ 2⌋) ÷ 4
In plain English: every Defence level adds 0.25 to your combat level. Same for Hitpoints. Prayer adds 0.25 for every two levels. That’s why Prayer feels slow—you need two levels to see the same gain as one Defence level.
Step 2: The Offensive Bonus Now the game looks at your combat style. It calculates three numbers and takes the highest:
- Melee: (Attack + Strength) × 0.325
- Ranged: ⌊Ranged × 1.5⌋ × 0.325
- Magic: ⌊Magic × 1.5⌋ × 0.325
Notice the ×1.5 for Ranged and Magic? That’s the secret. Each Ranged or Magic level is worth 50% more toward your combat level than a melee level. But—and this is critical—the maximum level for a Ranged or Magic-based account is only 109. To reach the max 126 combat level, you need to be melee-based.
The calculator handles all of this floor rounding automatically. You just see the final number.
Should You Trust an Online Combat Calculator With Your Progression Plan?
This is a fair concern. A lot of OSRS tools ask you to manually type in your levels, which is fine—you’re not sharing login details. But some calculators try to “save your progress” using cookies or even cloud storage. That’s unnecessary risk.
Here’s why this osrs combat level calculator is different: every single calculation happens inside your browser tab. The moment you load the page, the JavaScript code sits on your device. When you type your levels, the data never travels to a server. Not for “analysis,” not for ads, not for anything. This means you could be planning a maxed 126 combat path on a work laptop with strict IT policies, and nothing gets logged.
No uploads. No “create an account to save your build.” No tracking of your training priorities. It’s the same privacy model as a spreadsheet you’d build yourself—but with all the formulas pre-loaded and verified against the 2026 Wiki data.
From Level 3 to Level 126: Using the Planner for Your Whole Journey
The real power of this tool isn’t checking your level once. It’s using it every few days as you train.
Let’s say you’re a mid-level player at combat level 78. You run your current stats through the combat level calculator. The radar chart shows you’re heavily melee-based. The recommendation says: Train Ranged from 61 to 70. That feels counterintuitive—you’re a melee build, right? But the planner sees that your Ranged is low enough that each level gives you a huge +0.4875 toward the Ranged combat calculation, even though your melee path is your main. So for the next 5-10 hours, ranging will boost your overall combat level faster than any melee skill.
That’s the kind of insight you’d miss just looking at a level-up table.
For a pure magic build aiming for 109 (the magic-based cap), the calculator shows you exactly when switching to melee becomes more efficient. Usually, that’s around 95 Magic. The tool will flag: “Your magic bonus is plateauing. Training Attack and Strength to 80 will now give +0.65 per two levels.”
And because it never uploads your data, you can theory-craft your most private builds without a second thought. Try it with your current stats. You’ll probably find at least one skill you’ve been neglecting that’s worth more than you thought.
Frequently Asked Questions about Osrs Combat Calculator
How do I sanity-check the osrs combat result?
Rerun the calculator with a known example and compare it against the figure you expect; then swap back to your own numbers.
Which osrs combat inputs change the outcome most?
Adjust one field at a time. The figure that shifts the result hardest is the assumption worth double-checking before you rely on it.
Is this OSRS combat calculator accurate for the current 2026 game mechanics?
Yes, all calculations are pulled directly from the official Old School RuneScape Wiki formula, including the floor rounding on Ranged and Magic (⌊Ranged × 1.5⌋). The tool has been updated to reflect that there have been no changes to the core combat formula in recent years—what worked for a maxed main in 2023 still works today. You can verify any result by manually running the Wiki formula; the numbers will match exactly.
Do I need to download anything to use this free combat level calculator?
No. The tool runs 100% in your web browser using standard HTML, JavaScript, and Canvas for the charts. There’s no software to install, no mobile app to sideload, and no browser extension required. It works on desktop, tablet, and even large-screen phones, though the radar chart is easiest to read on a laptop or iPad. Because nothing is uploaded, you also don’t need an internet connection after the page loads—handy for playing on mobile data in low-signal areas.
Which skill gives the fastest combat level increase for a melee build?
For a pure melee build (level 90+ in Attack and Strength), the fastest gains come from training Defence or Hitpoints, as each level adds a flat 0.25 to your combat level. However, for most players below 80 Attack/Strength, training those two skills together is twice as effective: every two levels across both gives +0.65 total. The calculator’s “Level Planner” tab will show you your personal optimal skill based on your exact stats, because the answer changes depending on whether you’re level 40 or level 110.
Is it safe to use an online combat calculator for my OSRS main account?
Because this calculator never asks for your username, password, or any identifying information, the only risk is the same as typing numbers into any website: keyloggers on your own device. The tool itself does not store, transmit, or log any data. You can verify this by opening your browser’s developer tools (F12) and watching the Network tab—no requests are sent when you click “Calculate.” For absolute privacy, you can even save the webpage locally and use it completely offline.
