TTK Calculator (Time to Kill)

About the TTK Calculator (Time to Kill)

Time to kill (TTK) is arguably the most important metric in competitive FPS games. It measures how quickly a weapon can eliminate an opponent from full health, assuming every shot connects. Lower TTK means faster kills and less time exposed to return fire.

Unlike DPS, TTK accounts for the discrete nature of bullets. The first shot is instant (zero delay), and each subsequent shot requires one fire-rate interval. This means TTK equals the number of additional shots needed minus one, divided by the fire rate.

This calculator lets you quickly compare TTK across different weapons and health pools. In games like Call of Duty, Valorant, or Apex Legends, even a 50ms TTK difference between weapons can decide gunfights. Use This calculator to find the fastest-killing option for any scenario.

Use the estimate as a planning baseline and adjust it once you have real session data from the game you are playing.

When This Page Helps

TTK directly determines who wins a fair gunfight. If two players see each other at the same time, the player with a lower-TTK weapon has the advantage. This calculator helps you identify which weapons dominate at different health values, making it essential for competitive loadout optimization and understanding game balance patches.

How to Use the Inputs

1. Enter the enemy's total hit points (HP).
2. Enter the damage per shot for your weapon.
3. Enter the fire rate in rounds per second (divide RPM by 60 if needed).
4. View the TTK result in seconds and milliseconds.
5. Compare different weapons by changing the damage and fire rate inputs.
6. Adjust HP for different armor levels or character health pools.

Example Calculation

Tips & Best Practices

• Remember that the first shot has zero delay — TTK counts time between the first and last shots.
• Headshot damage can reduce shots-to-kill and dramatically lower TTK.
• In games with armor or shields, add those values to the base HP.
• TTK assumes perfect accuracy — real TTK is always longer due to missed shots.
• Burst weapons may have different intra-burst and inter-burst fire rates.
• Compare TTK at different ranges if your game has damage falloff.
• Lower TTK weapons reward aggressive play; higher TTK weapons reward tracking aim.

Why TTK Matters in Competitive Play

TTK is the fundamental metric that shapes the pace and feel of an FPS game. Games with fast TTK (under 300ms) emphasize positioning and first-shot advantage. Games with slow TTK (over 600ms) emphasize sustained aim tracking and movement.

TTK and Weapon Balance

Game developers carefully tune TTK when balancing weapons. A new weapon with a TTK just 30ms faster than the meta can completely shift the competitive landscape. This is why community weapons spreadsheets always include TTK calculations.

Beyond Optimal TTK

Optimal TTK assumes perfect accuracy, but real TTK includes missed shots and movement delays. The actual time to eliminate an opponent also depends on network latency, hit registration, and player reaction time. Use optimal TTK as a theoretical floor and expect real performance to be 20-50% slower.

Frequently Asked Questions

• What is TTK?

  TTK stands for time to kill. It's the time in seconds from the first bullet hitting an enemy to the killing blow, assuming every shot connects. It's the primary metric for comparing weapon lethality in FPS games.

• Why does the first shot not count in TTK?

  TTK measures the time between the first hit and the last hit. The first shot is instantaneous (time = 0), so only the intervals between subsequent shots contribute to the total time. That's why we subtract 1 from the shot count.

• How do I convert RPM to rounds per second?

  Divide the RPM (rounds per minute) value by 60. For example, 600 RPM ÷ 60 = 10 rounds per second. Many game wikis list fire rates in RPM, so this conversion is frequently needed.

• Does TTK account for reload time?

  No. TTK assumes you have enough ammo in the magazine to kill the target without reloading. If a weapon needs more shots than its magazine holds, actual kill time includes a reload penalty.

• How does TTK relate to DPS?

  DPS and TTK are closely related but not identical. DPS is a continuous measure, while TTK is discrete — it depends on exact shot counts. A weapon can have lower DPS but faster TTK against a specific HP value if it needs fewer shots to kill.

• What is a good TTK in FPS games?

  It varies by game. Call of Duty typically has 150-250ms TTK (fast), while Halo or Apex Legends ranges from 600ms to over 1 second (slow). Faster TTK games reward reaction time; slower TTK games reward tracking aim.
