CS2 TTK Calculator
Compute TTK/DPS with CS2's exact damage formula (base × hit multiplier × falloff × armor pen). Compare two weapons side by side.


Calculation Assumptions
- TTK is a theoretical value: it assumes 100% accuracy, continuous fire, and ignores reload and recoil (timing starts after the first hit).
- Armor follows the official percentage model: light absorbs 25% (capped at 25 per shot), heavy absorbs 50% (capped at 50 per shot).
- Shotguns assume all pellets hit (point-blank); real results vary with pellet spread.
- Alternate fire modes (bursts, ADS, etc.) are not modeled separately; primary fire rate is used.
AK-47 TTK is 300ms, in the "Medium" tier.
Get Your TTK in Three Steps
Choose weapon A from the dropdown (AK-47 by default); click Compare for weapon B. Filter by category to browse.
Pick hit part (head/body/stomach/leg), armor tier (none/kevlar/helmet) and drag the distance slider. CS2 armor resolves via each weapon's penetration %, legs ignore armor.
Shots-to-kill, TTK (ms), DPS and mag kills update live; compare mode highlights the faster weapon, and links are copyable.
What Is TTK (Time-to-Kill)?
TTK (Time-to-Kill) is the time between your first landed shot and the enemy going down — the core measure of a weapon's kill efficiency. TTK = (shots to kill − 1) × 60000 / RPM.
In CS2, shots-to-kill are set by hit multiplier × distance falloff × armor penetration: heads take 4×, stomach 1.25×, legs 0.75× but ignore armor; helmets protect only the head — AK-47 one-taps a bare head, and still one-taps through 77.5% pen, while the M4A1-S needs two. This calculator folds every variable into an exact TTK.
