Shotgun damage is per pellet. Time to kill assumes every shot hits.

How CS2 damage works

  1. Range falloff: damage is multiplied by the weapon's range modifier once for every 500 units (12.7 m) travelled, so a 0.98 rifle keeps 98% of its damage per 12.7 m and a 0.85 pistol only 85%.
  2. Hit location: the head uses the weapon's headshot multiplier (4× for most guns), the stomach takes 1.25×, chest and arms 1× and legs 0.75×.
  3. Armour: kevlar protects the chest, stomach and arms and a helmet protects the head. Armoured hits deal damage × armour penetration to health; legs are never armoured.
  4. Time to kill: the hits needed are fired at the weapon's fire rate, so a 600 RPM rifle that needs four hits kills in 300 ms.

Against kevlar at 15 metres, the AK-47 has the fastest chest time to kill of any rifle at 300 ms. Only AUG, SG 553, AK-47 can kill a helmeted player with a single headshot, and the AK-47 keeps that one-tap out to about 68 m. The calculator covers 34 guns and uses the same datamined values as our weapon pages.

CS2 damage calculator FAQ

How is damage calculated in CS2?

Damage = base damage × hit-location multiplier × range modifier ^ (distance in units ÷ 500). If the hit lands on armour, health damage is then multiplied by the weapon's armour penetration.

How far can the AK-47 one-tap a helmet in CS2?

About 68 metres. Past that distance, range falloff drops an AK-47 headshot on a helmeted player below 100 damage.

How much does armour reduce damage in CS2?

An armoured hit deals the weapon's armour-penetration percentage to health, for example 77.5% for the AK-47 and 70% for the M4A4. Half of the blocked damage is taken from the armour points instead.

Which rifle has the fastest time to kill in CS2?

Against kevlar at 15 metres with chest hits, the AK-47 is fastest at 300 ms. Headshots change the order, so try the calculator with different hit locations.

How many metres is a CS2 unit?

One Hammer unit is one inch, or 0.0254 m, so 500 units (the falloff step) is 12.7 m. The calculator accepts either metres or units.

What are the hitbox damage multipliers in CS2?

Head: the weapon's headshot multiplier (4× for most guns). Stomach: 1.25×. Chest and arms: 1×. Legs: 0.75×.

Does the calculator include wallbangs?

No. Shooting through walls and other players reduces damage further depending on the material and the weapon's penetration power, so the numbers here are for clean hits only.
