About the OSRS Max Hit Calculator
Work out your max hit with melee, ranged or magic from your levels, gear, prayers and potions. Add a target when the result depends on it, such as a Twisted bow, a salve amulet or a dragonbane weapon.
How to use the OSRS Max Hit Calculator
- Enter your combat levels or import them from the hiscores.
- Equip your weapon and gear, then set the attack style, prayers and potions under Boosts & style.
- Pick a target only when it matters: Twisted bow, salve amulet, dragonbane and demonbane weapons, and elemental weaknesses.
- Open View calculation to see each effect that was applied.
How the numbers are worked out
- Melee: effective strength is (Strength + potion boost) × prayer, rounded down, plus the style bonus and 8. Max hit is (effective strength × (strength bonus + 64) + 320) / 640, rounded down.
- Ranged works the same way with your Ranged level and ranged strength bonus.
- Void adds 10% to effective strength for melee and ranged; elite Void ranged adds 12.5%. Void mage adds no magic damage, and elite Void mage adds 5%.
- Magic starts from the spell's base max hit or the powered staff's own formula, then adds your magic damage bonus.
- Gear effects apply after the base. The salve amulet and slayer helmet do not stack. A Twisted bow uses the higher of the target's Magic level and magic attack, capped at 250 (350 in the Chambers of Xeric).
Frequently asked questions
How is max hit calculated in OSRS?
For melee and ranged, max hit = (effective strength × (strength bonus + 64) + 320) / 640, rounded down. Effective strength includes your potion boost, prayer, attack style and Void. Gear effects such as salve or a slayer helmet then raise the result.
Why is my magic max hit 0?
No spell or powered staff is selected. Pick a combat spell to autocast, or equip a powered staff such as a trident, Sanguinesti staff or Tumeken's shadow.
Why does my Twisted bow max hit change with the target?
The bow scales with the target's Magic level or magic attack, whichever is higher, capped at 250 outside the Chambers of Xeric. Pick the target to see the real number.
Does Void increase max hit?
Melee and ranged Void add 10% to effective strength, and elite Void ranged adds 12.5%. Void mage only raises magic accuracy; elite Void mage adds 5% magic damage.
Do prayers and potions stack?
Yes. The potion boost is added to your level first, then the prayer multiplies it. Only the strongest potion counts for each skill.
