OSRS Combat Level Calculator

This calculator is for informational purposes only. It uses the official Old School RuneScape combat formula but does not account for temporary boosts or equipment bonuses. Results are estimates based on skill levels alone.

Use this free online OSRS Combat Level Calculator to calculate your combat level. Simply enter your Attack, Strength, Defence, Hitpoints, Prayer, Ranged, and Magic levels to instantly get results in combat level. This shows your overall combat strength and which style contributes most to your level.

How Combat Level Is Calculated

Combat level in Old School RuneScape is calculated using a formula that combines your defensive skills and your highest offensive style. The game takes your Defence, Hitpoints, and half your Prayer level to form a base value. Then it calculates three separate offensive contributions: melee from Attack and Strength, ranged from your Ranged level, and magic from your Magic level. Only the highest of these three styles adds to your final combat level.

The formula always rounds down at each step. This means a Prayer level of 11 contributes the same as level 10, and your final combat level is always rounded down to the nearest whole number.

What Your OSRS Combat Level Result Means

Your combat level represents your overall fighting strength in Old School RuneScape. It helps other players quickly assess your combat capabilities. The maximum combat level is 126, which requires 99 in all combat skills. Players often build their accounts to keep combat level low while maximizing offensive power, creating "pure" accounts that excel in player versus player combat at specific level brackets.

Your dominant combat style shows which of melee, ranged, or magic contributes most to your combat level. A pure account focuses on just one offensive style while keeping Defence and Hitpoints low.

Accuracy, Limitations & Common Mistakes of the OSRS Combat Level Calculator

How Accurate Is the OSRS Combat Level Calculator?

This calculator uses the exact formula from Old School RuneScape. The results match what you see in-game for any valid skill level combination. However, the calculator only uses your base skill levels. It does not account for temporary boosts from potions, special attacks, or equipment that might temporarily raise your skills.

Limitations of the OSRS Combat Level Calculator

The calculator does not include temporary skill boosts from potions or food. It does not show your combat level with different equipment setups. The calculator cannot predict your performance in actual combat, as that depends on gear, strategy, and experience. It also does not account for PvP combat brackets or minigame level requirements.

Common Mistakes to Avoid

• Entering boosted levels instead of base levels. Always use your unboosted skill levels as shown in the skills tab.
• Forgetting that only your highest combat style counts. Training all three styles evenly will not increase your combat level faster.
• Not checking the dominant style. Understanding which style drives your combat level helps you plan your build.
