How to Use the OSRS Combat Calculator
- Enter your skill levels (1–99) in the fields: Hitpoints, Attack, Defence, Strength, Magic, Ranged, and Prayer. All fields are required.
- Optional: Check the PvP formula box if you want the PvP variation (which multiplies Prayer by 1.5 before halving).
- Click "Calculate Combat Level" — the result appears below, along with the formula used.
- Interpret the result: Your combat level is a whole number. The formula uses the highest of Melee, Ranged, or Magic bonuses plus a base from Defence, Hitpoints, and Prayer.
Tip: All inputs must be between 1 and 99. Invalid entries will show an error message.

Frequently Asked Questions
Combat level is calculated using a formula that considers Defence, Hitpoints, Prayer, Attack, Strength, Ranged, and Magic. The base is 0.25*(Defence + Hitpoints + floor(Prayer/2)), then the max of melee, ranged, or magic bonuses is added. For PvP, Prayer is multiplied by 1.5 before halving.
The maximum combat level is 126 for normal accounts (with 99 in all relevant skills) and 127 for PvP worlds due to the boosted Prayer weighting.
Combat level only increases when the sum of your base and the highest combat style bonus crosses an integer threshold. Sometimes multiple level-ups are needed for a single combat level increase.
