CS2 Damage Calculator

Knowing how many shots it takes to kill — and whether a headshot one-taps through a helmet — is fundamental CS2 knowledge. This free damage calculator shows exact weapon damage by hitbox, armor type, and distance for every rifle, pistol, SMG, sniper, shotgun, and heavy gun in Counter-Strike 2.

Toggle Kevlar, Kevlar + Helmet, or no armor to see how armor penetration affects body and head damage. Drag the range slider to model distance falloff. The comparison table ranks all weapons by headshot damage at your current range so you can quickly see which guns one-tap.

The Knife tab covers slash, stab, and backstab attack types with correct armor behavior. The Grenades tab models HE proximity damage, molotov and incendiary fire DPS, and utility nade chip damage. Figures use community-estimated values — close guides for learning, not official Valve numbers.

CS2 armor penetration explained

Kevlar reduces body damage based on each weapon's armor penetration stat. A helmet protects the head from most rifles at range, but high-penetration weapons like the AK-47, Desert Eagle, and AWP still one-shot through helmet at close to medium range.

The M4A1-S and M4A4 typically need two headshots to kill a helmeted target unless the enemy has low HP. Against unarmored eco players, most rifles kill with a single chest shot.

Which CS2 weapons one-tap through a helmet?

The AWP is lethal on almost any clean hit regardless of armor. The AK-47 and Desert Eagle reliably one-tap a helmeted head at close to medium range. The SG 553 and AUG with their scopes also deal enough headshot damage to one-tap at most ranges.

Use the weapon comparison table above to check headshot damage for every gun at your selected range. If headshot damage exceeds 100 HP after armor reduction, the weapon one-taps.

Grenade damage in CS2

HE grenades deal up to 98 HP at the blast center (57 HP vs armored targets). Molotovs and incendiary grenades ramp to 40 DPS and ignore armor entirely. Flash, smoke, and decoy grenades deal minimal chip damage but provide crowd control — smokes block vision for ~18 seconds and flashes blind for up to several seconds depending on angle.
