Combat Level Calculator

Ever wondered what your combat level would be if you bumped up that Attack stat? Or maybe you’re trying to stay at a specific combat bracket for PKing? Trust me, I’ve been there countless times. After years of playing Old School RuneScape and constantly doing mental math (and getting it wrong half the time), this combat level calculator has become my go-to tool for planning character builds.

What Makes This Calculator Special?

This isn’t just another basic calculator you’ll find scattered across random forums. What sets this tool apart is its intelligent hitpoint estimation feature. Here’s the thing – most calculators assume you’ve trained all your combat skills naturally, but we both know that’s not always the case.

Have you ever spent hours alching to get your Magic up? Or maybe you’re one of those players who cannoned their way to 99 Ranged without gaining a single hitpoint? This calculator gets it. You can actually exclude specific skills from the HP estimation, which gives you way more accurate results.

How Does It Actually Work?

The interface is pretty straightforward, but let me walk you through it like I’m explaining it to a clan mate:

Player Name Entry: You can input any player’s name to pull their current stats. Super handy when you’re helping friends plan their builds or just being nosy about someone’s progress.

Manual Stat Input: Each combat skill has those familiar + and – buttons. Click away to test different stat combinations. I usually start with my current stats and then play around with “what if” scenarios.

The Magic Behind HP Estimation: This is where things get interesting. The calculator can estimate your hitpoints based on your other combat stats, but here’s the clever part – you can exclude Magic and Ranged if you’ve trained them through non-combat methods.

Why does this matter? Well, let’s say you’ve been splashing or alching for weeks to get 94 Magic for Vengeance. Your Magic level doesn’t reflect any HP gained from combat training. Same goes for Ranged if you’ve been using a cannon or chinning in a safe spot.

Real-World Applications (From Someone Who Actually Uses It)

Pure Build Planning: When I was working on my range pure, this calculator saved me from so many mistakes. You know how easy it is to accidentally get one too many Defence levels and ruin your entire build? Been there, done that, learned the hard way.

Main Account Progression: On my main, I use this constantly to plan which stats to train next. Sometimes you want to stay at certain combat brackets for specific activities. Other times you’re trying to reach that next milestone as efficiently as possible.

PKing Bracket Management: If you’re into PvP, you’ll love this. Want to stay at combat level 88 for those sweet Barrows gloves fights? Or maybe you’re trying to hit exactly 126 combat for max main PKing? This calculator shows you exactly how to get there.

The Technical Stuff (But Keep It Simple)

The combat level formula in OSRS isn’t exactly rocket science, but it’s not intuitive either. Your combat level is calculated using this formula:

Base Level = 0.25 × (Defence + Hitpoints + floor(Prayer/2))

Then you add the highest of these three values:

• 0.325 × (Attack + Strength)
• 0.325 × (floor(Ranged × 1.5))
• 0.325 × (floor(Magic × 1.5))

Sounds complicated? That’s exactly why this calculator exists. Who wants to do that math every time you’re planning a stat change?

Features That Make Life Easier

Auto Calculate Toggle: Leave this on if you want real-time updates as you adjust stats. Turn it off if you’re making lots of changes and don’t want the constant recalculation.

Skill Exclusion Options: This is the game-changer. You can exclude Magic or Ranged from HP calculations if you’ve trained them through non-combat methods. Finally, a calculator that understands how people actually play the game.

Instant Results: No waiting, no page refreshes. Change a stat, see the result immediately.

Common Questions I Get About Combat Calculations

“Why is my estimated HP different from my actual HP?”

This usually happens because you’ve done some non-combat training. Maybe you’ve been doing quests that give HP experience, or you’ve been training skills that don’t normally give HP. The exclusion feature helps with this, but sometimes your training history is just unique.

“Can I use this for planning pure builds?”

Absolutely. In fact, that’s one of the main reasons I use it. Planning a 1 Defence pure? Want to see how high you can get your combat stats while staying at a specific combat level? This tool makes it super easy to experiment with different combinations.

“What about quest rewards and lamp experience?”

The calculator works with whatever stats you input, so if you’re planning around quest rewards, just add those experience gains to your projected levels before calculating.

Why Accuracy Matters in Combat Planning

I learned this lesson the hard way on my first pure attempt. I was using a basic calculator that didn’t account for my training methods, and I ended up with completely wrong HP projections. Wasted weeks of training because I miscalculated my final combat level.

The thing about OSRS is that one level can make or break your build. Whether you’re trying to stay in a specific PvP bracket or reach a certain combat level for bossing, precision matters. This calculator gives you that precision.

Tips From My Experience

Always double-check your exclusions: If you’re using the HP estimation feature, make sure you’re excluding the right skills. I once forgot to exclude Magic after weeks of alching and got completely wrong results.

Plan ahead for quest requirements: Some quests give unavoidable combat experience. Factor these in before finalizing your build plans.

Consider your training methods: Are you planning to chin Ranged? Burst Magic? Train Strength with a whip? Your training method affects how much HP you’ll gain.

The Bottom Line

Look, there are plenty of combat calculators out there, but most of them are either too basic or don’t understand how people actually train in OSRS. This one gets it right. The HP estimation with skill exclusions alone makes it worth bookmarking.

Whether you’re a seasoned player planning your tenth alt account or a newer player trying to understand combat levels, this calculator removes the guesswork. No more spreadsheets, no more manual calculations, no more “oops, I ruined my pure” moments.

Give it a try with your current stats first, then start experimenting with those dream builds you’ve been thinking about. You might be surprised at what’s actually achievable with smart planning.
