How the Combat Calculator OSRS Works

Enter your current levels or fetch them from the hiscores. The calculator uses the official OSRS combat formula to compute your precise combat level, identify your dominant combat style, and suggest the fastest single-skill increases to reach the next level.

1) Input Your Stats

Provide levels for Attack, Strength, Defence, Hitpoints, Prayer, Ranged, and Magic (between 1–99). You can also fetch stats by display name.

2) Optional HP Estimation

Toggle Estimate Hitpoints to infer HP based on average XP from your selected combat skills. Exclude Magic/Ranged if you trained them in ways that give no HP XP (e.g., alching, cannoning).

3) Review Results & Tips

See your combat level (1 decimal) , detected combat type (Warrior / Ranger / Mage), and next-level suggestions showing the fewest levels needed in a single skill to increase your displayed combat level.

Combat Level Formula

The calculator uses the standard OSRS formula. We compute a base value from Defence, Hitpoints, and Prayer , then add the largest of the three offensive styles (Melee, Ranged, Magic). 

base = 0.25 × (Defence + Hitpoints + ⌊Prayer / 2⌋)

melee = 0.325 × (Attack + Strength)
ranged = 0.325 × ⌊Ranged × 1.5⌋
magic = 0.325 × ⌊Magic × 1.5⌋

combat = base + max(melee, ranged, magic)

Notes: We display one decimal for precision, but level-ups and suggestions compare using ⌊combat⌋ (the integer combat level shown in-game).

Dominant Combat Type

Your style is determined by whichever of melee, ranged, or magic produces the highest contribution in the formula.

Next-Level Suggestions

For each skill, we simulate level increases (up to 99) until ⌊combat⌋ rises. The UI then lists the fewest levels needed per skill to reach the next combat level.

HP Estimation (Optional)

When enabled, Hitpoints is estimated from the average XP of your chosen combat skills (excluding any you mark). This mirrors common training patterns while letting you model niche methods.

Range/Mage rounding: their contributions use ⌊level × 1.5⌋ , which can shift breakpoints.

Prayer halves: only ⌊Prayer / 2⌋ is counted in the base component.

Cap awareness: Skills cap at 99 and combat level caps at 126.

Frequently Asked Questions

Which skills affect my Old School RuneScape combat level in this calculator?
The calculator uses Attack, Strength, Defence, Hitpoints, Prayer, Ranged, and Magic. Non-combat skills (like Slayer or Agility) do not affect combat level.
How does the calculator compute my combat level?
It applies the standard OSRS formula: base = 0.25 × (Defence + Hitpoints + ⌊Prayer/2⌋), melee = 0.325 × (Attack + Strength), ranged = 0.325 × ⌊Ranged × 1.5⌋, magic = 0.325 × ⌊Magic × 1.5⌋, then Combat = base + max(melee, ranged, magic). The result is shown to 1 decimal for precision.
What does the 'Estimate Hitpoints' option do?
When enabled, Hitpoints is estimated from the average XP of your selected combat skills (Attack, Strength, Defence, and optionally Ranged and Magic). You can exclude Magic or Ranged if you trained them without HP XP (e.g., alching, cannoning).
Why does the calculator show a decimal combat level when the game shows a whole number?
The game displays the floored integer value. The calculator shows one decimal place so you can see how close you are to the next level. Your displayed level increases when ⌊combat⌋ increases.
How are the 'Next level' suggestions generated?
For each relevant skill, the tool simulates level increases up to 99 and finds the smallest increase that would raise ⌊your combat level⌋ by at least 1. It then lists those minimum level gains per skill.
Can I fetch my stats automatically by username?
Yes. Enter your display name and fetch. The tool requests your public hiscore stats and fills in the skill levels, which you can still edit manually afterward.
What is the maximum combat level and what happens at max?
The maximum combat level in OSRS is 126. Once you reach it, the calculator will indicate that you are maxed and no further suggestions are needed.
How accurate is this calculator?
It follows the official OSRS formula and rounding rules (e.g., ⌊Prayer/2⌋ and ⌊Ranged×1.5⌋/⌊Magic×1.5⌋). Results should match the in-game value when using the same levels.
