OSRS Combat Calculator
Enter your skill levels to find your exact combat level and see how many levels you need to rank up.
In Old School RuneScape (OSRS), your Combat Level is the ultimate indicator of your strength. It determines which monsters are aggressive toward you, what Slayer Masters you can use, and most importantly, which players you are allowed to attack in PvP and the Wilderness.
However, the game doesn’t explicitly tell you how close you are to leveling up. A player with level 85 combat could actually be level 85.99, meaning just one more stat increase would push them to level 86.
Our free OSRS Combat Calculator uses the exact game engine algorithm to calculate your raw combat level. Simply input your current skills, and the tool will instantly tell you your exact combat level, your dominant combat class, and exactly how many skill levels you need to grind to reach your next rank!
How is Combat Level Calculated in OSRS?
In OSRS, every player starts at Combat Level 3 and can achieve a maximum of Combat Level 126. This number is not an average of your stats; it is calculated using a complex formula that divides your skills into two specific categories:
1. Base Stats (Always Counted) Your Defence, Hitpoints, and Prayer levels are considered your “Base” stats. These levels will always contribute to your overall combat level, regardless of what weapon you are holding. (Note: Because of how the math works, Prayer only contributes to your combat level on every even number. Getting level 2 Prayer matters, but getting level 3 Prayer does not change your combat level!)
2. Class Stats (Only the Highest is Counted) Your Melee (Attack + Strength), Ranged, and Magic levels are your class stats. The game calculates the combat impact of all three categories, but it only adds the highest one to your Base stats.
For example, if you have 99 Magic but only 10 Attack, leveling your Attack to 11 will not increase your combat level because your Magic stat is already so high that it dominates the equation.
Why Use a Combat Calculator?
Because of how the OSRS math works, players use our calculator to perfectly optimize their accounts, especially for Player vs Player (PvP) combat.
In PvP, you want to deal the maximum amount of damage possible while keeping your overall combat level as low as possible. Players create specialized accounts (known as “Pures,” “Zerkers,” or “Mains”) where they intentionally stop leveling Defence and Prayer so they can dump all of their stats into Strength and Magic.
By using the “Levels Needed For Next Combat Level” section of the calculator above, you can plan your account build perfectly. It tells you exactly how many levels you can gain in a specific skill before the game forces your overall combat level to rank up!
Frequently Asked Questions (FAQs)
What is the maximum Combat Level in OSRS?
The maximum combat level in Old School RuneScape is 126. To reach level 126, a player must achieve level 99 in Attack, Strength, Defence, Hitpoints, Prayer, and either Magic or Ranged.
Does Summoning affect Combat Level?
No. While Summoning affected combat levels in the original RuneScape 2 (raising the max combat level to 138), the Summoning skill does not exist in Old School RuneScape.
What does “Melee Based” or “Ranged Based” mean?
Because the game only adds your highest damage category to your base stats, your account is considered “based” around that stat. If your Magic level is mathematically contributing more to your combat level than your Attack and Strength combined, the calculator will tell you that you are “Magic Based.”
