Time-to-Kill (TTK) Calculator
How long to kill a target from your DPS and its effective HP — the metric that defines a shooter's feel.
TTK defines a shooter's identity: low TTK (CS, Valorant — sub-0.5s) rewards aim and positioning; high TTK (Apex, Overwatch — 1–2s+) rewards tracking, abilities and team play. Weakpoint multipliers reward precision by raising effective DPS. This is the first number to tune when a game feels 'off'.
Formula
About Time-to-Kill (TTK) Calculator
Time-to-kill is the number that defines how a shooter feels: it's simply a target's effective HP divided by your effective DPS, but it determines whether gunfights reward twitch aim or sustained tracking, whether positioning errors are instantly fatal, and how much room abilities and teamplay have to matter. This calculator computes TTK including weakpoint/headshot multipliers, which raise effective DPS by rewarding precision. It's the first lever designers pull when combat feels too punishing or too forgiving, and the metric competitive players obsess over.

Frequently asked questions
What TTK makes a shooter feel a certain way?+
Low TTK (under ~0.5s, like CS or Valorant) makes first-shot accuracy and positioning decisive — fights end instantly, so being seen first usually means dying. High TTK (1–2s+, like Apex or Overwatch) creates extended duels where tracking, movement, cooldowns and teammates can turn a fight. Neither is 'correct'; they define different competitive identities.
How do weakpoints/headshots change TTK?+
They multiply effective DPS for the fraction of shots that land on the weakpoint: effective DPS = DPS × (1 + weakpointRate × (multiplier − 1)). A 2× headshot multiplier with 50% headshot rate is +50% DPS, cutting TTK by a third. This rewards precision and creates the skill gap between average and elite aim — a core balance lever.
Why is TTK the first thing to tune?+
Because it cascades into everything: movement speed (can you escape?), ability power (do cooldowns matter in a fight this short?), health/shield design, and even map sightlines. Changing weapon damage or fire rate to hit a target TTK is often the single highest-impact balance change, which is why it's where tuning starts.
Does TTK account for accuracy and reload?+
This calculator uses your effective DPS, which should already fold in your real accuracy. For full fidelity, also model magazine size and reload (TTK can require a reload mid-fight, spiking real kill time) and recoil-driven accuracy falloff during sustained fire. Use this as the idealized TTK and adjust for those frictions per weapon.
