Combat Level Calculator for Old School RuneScape
Type your seven combat stats and get your combat level, which style is driving it, and how many levels in each stat would raise it by one. Your inputs stay in the link.
How combat level works
Your combat level has a base from Defence, Hitpoints and Prayer, plus the best of three style terms: melee (Attack + Strength), ranged or magic. Only the best term counts, so a pure account can hold a low combat level while one style is maxed. The result is rounded down; the table shows how far each stat is from pushing you over the next whole number, so you know which level-up is "safe" if you are keeping combat low for PvP brackets.
The formula with a worked example is on the how it's calculated page; for your damage see the max hit calculator.
FAQ
Which stats raise combat level the most?
Attack and Strength each add 0.325 per level when melee is your highest style, Ranged and Magic add 0.4875 per level (0.325 × 1.5) when they lead, Defence and Hitpoints add 0.25, Prayer adds 0.125 (0.25 per two levels).
Why does training Magic not change my combat level?
Only the highest of melee, ranged and magic counts. If your melee term is higher than your magic term, magic levels do nothing until the magic term overtakes it.
What is the maximum combat level?
126, reached with 99 in Attack, Strength, Defence, Hitpoints, Prayer and either Ranged or Magic at 99 does not matter once melee leads. The minimum is 3.
Does Summoning or boosting count?
Old School has no Summoning. Combat level uses base levels only; potions and prayers do not change it.
