Max Hit Calculator for Old School RuneScape
Pick a style, enter your level and bonuses and read the max hit. Every input is saved in the link so you can share a setup.
Reading the result
Melee and ranged max hits come from an effective level (your level after the prayer multiplier, the attack-style bonus and +8, times 1.1 for void) and the equipment bonus. Each later multiplier such as the slayer helmet is applied to the whole number and rounded down again, which is why two bonuses sometimes add one point less than you expect.
Magic works differently: each spell has a fixed base hit (powered staves scale with your Magic level), multiplied by your total magic damage percentage. Details and worked examples are on the how it's calculated page. Your combat level is on the combat level calculator.
FAQ
Where do I find my strength bonus?
Open the Equipment Stats screen (the shield icon in the Worn Equipment tab). Use "Melee strength" for melee, "Ranged strength" for ranged and "Magic damage" for magic. Potions change your level, not the bonus: enter the boosted level.
What does the attack style add?
Aggressive adds +3 to your effective Strength level, Controlled +1, Accurate and Defensive nothing. For ranged, Accurate adds +3 and Rapid or Longrange nothing. The bonus is added after the prayer multiplier.
How do the slayer helmet and salve amulet stack?
For melee and ranged they are separate multipliers applied one after another with rounding down each time, but the salve amulet overrides the slayer helmet bonus against undead: you get the better one, not both. For magic they add to your magic damage percentage.
Why is the magic max hit lower than in game?
Check that the Magic damage % matches your equipment screen, including the magic damage from the occult necklace and tormented bracelet, and that you selected the right spell. Powered staves scale with your visible Magic level, so enter the boosted level if you used a potion.
