How OSRS Equipment Calc Works

To use the OSRS Equipment Calc, enter your Strength level and each slot’s attack, Strength, defence and Prayer bonus, then read your totals and max hit.

  1. Enter your visible Strength level.
  2. Pick a 1-handed weapon with shield or a 2-handed weapon.
  3. Enter the bonuses for weapon, head, body, legs and shield.
  4. Enter the combined bonuses of every other slot in Other.
  5. Read the totals and the aggressive melee max hit without prayer.

OSRS Equipment Calc Formula

The OSRS Equipment Calc formula is Total bonus = the sum of each worn slot’s bonus, with the shield removed for 2-handed weapons.

Total = weapon + head + body + legs + shield + other
2-handed weapon: Total = weapon + head + body + legs + other
Max hit = ⌊0.5 + (Strength + 3 + 8) × (Strength bonus + 64) ÷ 640⌋

  • Attack and defence must use the same type: stab, slash or crush.
  • Other covers cape, neck, ammunition, hands, feet and ring.
  • The max hit uses the aggressive style (+3) and no prayer.

OSRS Equipment Calc FAQ

How do I check my equipment bonuses in OSRS?

To check equipment bonuses in OSRS, open the Worn Equipment tab and click View equipment stats. The screen lists every attack, defence and other bonus.

Why does a 2-handed weapon remove the shield?

A 2-handed weapon removes the shield: a 2-handed weapon fills both the weapon and shield slots, so shield bonuses do not count.

Does Prayer bonus change damage?

No, Prayer bonus does not change damage. Prayer bonus makes Prayer points last longer.

What does +1 Strength bonus add to max hit?

+1 Strength bonus adds about 1/640 of your effective Strength to max hit. At 118 Strength, about 5 Strength bonus raises max hit by 1.
