Max Hit Calculator FAQ
How is max hit calculated in OSRS?
For melee, effective Strength = floor((Strength + potion) x prayer) + style bonus + 8, then max hit = floor(0.5 + effective Strength x (Strength bonus + 64) / 640). Ranged uses the same shape with Ranged strength; magic scales a spell's base max by your magic damage bonus.
Does Prayer increase your max hit?
Yes. Piety adds 23% Strength, Chivalry 18%, Ultimate Strength 15%. Ranged has Rigour (+23%) and magic has Augury. The prayer multiplier is applied before the +8, which is why it matters so much at high levels.
Do potions raise your max hit?
Yes. Super strength gives +5 and 15% of your level, Overloads a bit more, and ranging or magic potions boost their stats. Pick your potion in the calculator and the max hit updates instantly.
Does this max hit calculator work for ranged and magic?
Yes. Switch the style tab to Ranged or Magic. Ranged uses your Ranged level and ranged strength bonus; magic takes your spell's base max hit and your magic damage percentage from gear like the occult necklace.
Does the Slayer helmet increase max hit?
On a Slayer task, the imbued Slayer helmet multiplies your max hit by 7/6 (about +16.7%) for all three styles. The imbued Salve amulet does the same or more against undead. Select the effect in the calculator to include it.
What is the highest max hit in OSRS?
Regular hits from gear top out in the 60s to low 70s with the strongest setups and boosts, while special attacks and unique mechanics can go far higher. This calculator covers your standard per-hit max for planning DPS.
