Deadlock Damage Calculator
Calculate Deadlock bullet and ability damage with weapon %, flat damage, falloff, headshots, Spirit Power scaling, stacking resists and shred, plus hits to kill.
Uses the community-documented damage formulas (checked October 2026). Enter ability and item numbers from the in-game tooltips—they change every patch.

How this estimate works
Gun and ability damage follow different rules in Deadlock, so the calculator has two modes. The formulas come from community documentation (the Deadlock Wiki and deadlock.io), last checked October 2026. The game doesn't publish them, so confirm important numbers in the sandbox.
Gun damage = [(base × (1 + weapon%)) + flat] × falloff × (1 − effective resist) × headshot × (1 + bullet amp).
- Weapon damage % scales base damage only. Flat bonuses are added afterwards.
- Falloff drops damage linearly from 100% to 10% across your hero's falloff range.
- Resists stack multiplicatively, 1 − (1 − r₁)(1 − r₂)…; shred stacks the same way and is then subtracted from the total. Negative results are treated as bonus damage.
- Headshots multiply by 1 + (0.65 + hero modifier) × crit resist, so 1.65× for most heroes and less for some.
Ability damage = (base + Spirit Power × coefficient) × (1 − effective spirit resist) × amps. Spirit scaling is a flat add per point of Spirit Power, not a percentage of base damage. Percent bonuses to Spirit Power multiply with each other and raise the Spirit Power figure itself.
Not modelled: damage over time ticks, ability-specific rules, barriers, healing, lifesteal and conditional item effects. Use the numbers on your tooltips as inputs and treat the output as a close estimate.
