Question 1

How is CS2 weapon damage calculated?

Accepted Answer

Effective damage starts from the weapon’s base damage, then multiplies by the body-part hitbox: head ×4.0, stomach ×1.25, chest/arm ×1.0, leg ×0.75. Distance applies a falloff (roughly 100% at point-blank, ~60% at cross-map ranges of 1500+ units), then armor reduces damage scaled by each weapon’s armor-penetration value.

Question 2

Does Kevlar armor reduce damage in CS2?

Accepted Answer

Yes. Body armor (Kevlar) reduces damage to chest, stomach, and arm shots; the helmet reduces head shots. Leg shots are never reduced by armor. The reduction depends on each weapon’s armor-penetration value, so high-pen guns like the AK-47 (0.775) lose far less damage through armor than a Glock (0.47) does.

Question 3

What is the AK-47 one-tap range in CS2?

Accepted Answer

The AK-47 one-shots a helmeted target with a headshot at any range. Its base damage is 36 and the head multiplier is ×4, so even after helmet reduction and full distance falloff the headshot damage stays above 100 HP. That’s why it’s the T-side flagship rifle.

Question 4

How does damage falloff work in CS2?

Accepted Answer

Damage decreases gradually with distance. As a working approximation, expect close to 100% damage at point-blank, roughly 70% damage near 1000 units, and a plateau around 60% beyond 1500 units (cross-map). Real per-weapon falloff curves are weapon-specific and not fully public, but this approximation is accurate within about 5 HP at typical engagement ranges.

Question 5

What is time-to-kill (TTK) in CS2?

Accepted Answer

Time-to-kill is how long it takes one weapon to deal 100 HP at its rate of fire. The calculator computes it as (hits-to-kill − 1) × (60,000 ms / RPM), since the first shot lands instantly and only the gaps between subsequent shots add time. A 600 RPM AK firing two body shots takes ~100 ms.

Weapon	Damage	Hits	TTK	Cost
AK-47	32	4	300ms	$2,700
M4A4	28	4	270ms	$3,100
M4A1-S	32	4	300ms	$2,900
AWP	114	1	—	$4,750
SSG 08	81	2	1250ms	$1,700
Desert Eagle	51	2	225ms	$700
Galil AR	27	4	300ms	$1,800
FAMAS	26	4	270ms	$1,950
MP9	21	5	280ms	$1,250
