How do you calculate TTK in FPS games?

TTK (Time to Kill) = (Shots to Kill - 1) / Fire Rate. Shots to Kill = ceil(Target HP / Damage per Shot). For example, a weapon dealing 34 damage per shot at 600 RPM against a 100 HP target requires ceil(100 / 34) = 3 shots, giving a TTK of (3 - 1) / (600 / 60) = 0.2 seconds. Subtract 1 from shots because the first shot fires instantly at time zero.

What is the fastest TTK in Valorant?

In Valorant, the Sheriff has a one-shot headshot TTK of 0ms at close range against unarmored opponents (0.17s TTK with a single body shot). Among automatic weapons, the Vandal and Phantom are the primary rifles — both have a TTK of approximately 276ms for three body shots. The Operator one-taps to the body at full health, giving a 0ms effective TTK for a well-placed shot.

How does armor affect TTK?

Armor adds effective HP that must be depleted before base health, directly increasing TTK. In Apex Legends, a purple shield adds 100 HP (total 225 HP), increasing a weapon's shots to kill and TTK significantly. In COD Warzone, armor plates add 50 HP each, with up to three plates raising effective HP to 300. Games handle armor penetration differently — some weapons deal reduced damage to armor, others bypass it entirely, making armor TTK calculations game-specific.

What is the difference between TTK and STK?

TTK (Time to Kill) measures the elapsed time in seconds from the first shot to the killing shot. STK (Shots to Kill) is simply the number of bullets required to eliminate a target. STK is the more useful metric for semi-automatic and single-shot weapons like the AWP or Sheriff where shot timing is manual. TTK is more meaningful for automatic weapons where fire rate determines how quickly shots are delivered. Both metrics assume all shots hit.

Does damage falloff affect TTK at range?

Yes — most FPS weapons deal reduced damage beyond certain distances, which increases shots to kill and therefore TTK. In Apex Legends, most ARs begin damage falloff at 28–35 meters. In COD Warzone, SMGs often drop to 60–70% damage at long range, potentially adding one or two extra shots to kill. When comparing weapons at range, always account for their damage falloff profiles — a weapon with a faster close-range TTK may be slower at medium range than a weapon with better damage retention.

Optimize Your TTK

Master these techniques to minimize time to kill and win more gunfights

⚡ Minimize TTK

• Aim for the head - headshot multipliers dramatically reduce TTK
• Use weapons with high fire rates for faster eliminations
• Practice tracking to land consecutive shots quickly
• Learn optimal engagement ranges for your weapon
• Prefire common angles to get first shot advantage

🔫 Weapon Selection

• Choose weapons with fast TTK for your playstyle
• High damage weapons excel at range, high ROF up close
• Consider magazine size for multi-kill potential
• Balance TTK with ease of use and recoil control
• Meta weapons often have optimal TTK for their class

📍 Positioning & Timing

• Engage at optimal range for your weapon's TTK
• Get first shot to win equal TTK encounters
• Use cover to extend enemy TTK against you
• Strafe and move unpredictably during gunfights
• Disengage if you lose TTK advantage

⚙️ TTK Optimization

• Burst fire to maintain accuracy and faster effective TTK
• Reload in cover to maintain optimal TTK uptime
• Avoid leg shots - they increase TTK significantly
• Practice spray control for consistent body/head shots
• Know your weapon's damage profile and dropoff ranges
