How the OSRS combat level calculator works

Your combat level in Old School RuneScape is a weighted value based on your core combat stats. This number affects where you land in PvP brackets, who can attack you in the Wilderness, and how your account build performs in duels and minigames.

This calculator uses the official OSRS combat formula. It computes your base combat value from Defence, Hitpoints, and Prayer, then adds your strongest offensive style (Melee, Ranged, or Magic). The final value is rounded down to a whole number, which is exactly how the game displays combat level.

Official OSRS combat formula

base = 0.25 × (Defence + Hitpoints + floor(Prayer / 2)) melee = 0.325 × (Attack + Strength) ranged = 0.325 × floor(Ranged × 1.5) magic = 0.325 × floor(Magic × 1.5) Combat Level = floor(base + max(melee, ranged, magic))

Key detail: Ranged and Magic are multiplied by 1.5 before being floored, which is why pure builds can gain strong combat effectiveness without investing in all melee stats.

Why this matters for account builds

Main accounts

If you are building a balanced main, combat level progression is straightforward. Your base (Defence/Hitpoints/Prayer) and offense usually rise together through regular PvM and Slayer training. This calculator helps you time upgrades, quest unlocks, and boss readiness checkpoints.

Pure accounts

For pures, every combat level is strategic. You often want to maximize damage while staying in a favorable PvP bracket. Calculating your next level in advance can help you avoid accidentally over-leveling before a tournament, bounty setup, or PK trip.

Zerker and med-level builds

Zerker and med builds rely on controlled Defence and Prayer milestones. A calculator makes it easier to map your plan before expensive grinds like Piety unlocks, ranged burst sessions, or melee strength training.

Training tips to optimize combat level gains

Track Prayer carefully: Prayer contributes at half rate (floored), so level breakpoints matter.
Know your dominant style: If melee is dominant, raising Attack or Strength usually improves combat value more than Ranged/Magic.
Use build checkpoints: Plan around target combat levels (for example 60, 75, 88, 100, 126).
Avoid accidental level jumps: Especially important for PvP accounts and wilderness matchmaking.
Pair with gear progression: Combat level is one piece of the puzzle; weapon unlocks and prayer books often matter more than a single level.

OSRS combat calculator FAQ

What is the max combat level in OSRS?

The maximum combat level is 126.

Does Hitpoints affect combat level?

Yes. Hitpoints is part of the base calculation and contributes directly to your combat level.

Why did my Prayer level not increase combat level immediately?

Prayer is halved and floored in the formula, so some levels do not increase your displayed combat until the next breakpoint.

Do Summoning or Constitution affect OSRS combat level?

No. This is Old School RuneScape, so Summoning is not part of the combat formula. Hitpoints uses the OSRS system and is included as shown above.

Final thoughts

A good OSRS combat level calculator is more than a number tool—it is a planning assistant for PvM progression and PvP efficiency. Use it before major training sessions, before quest reward claims, and whenever you are tuning a specialized build. A few minutes of planning can save hours of rework and help you stay in the ideal combat bracket for your goals.
