FPS Ammo Calculator
Estimate hits, total shots and magazine needs to take down a target.
Use this FPS ammo calculator when you want to estimate how many shots it takes to eliminate a target based on enemy health, damage per shot, your average accuracy and magazine size. It is useful for weapon comparison, loadout planning, aim practice and quick checks on whether one magazine is usually enough for a standard duel.
Enter target health, damage per shot and expected accuracy to see the minimum hits needed and the likely number of total shots fired before the kill happens. If you also provide magazine size, the tool estimates how many magazines, full or partial, that exchange would consume.
This is still a planning reference, not a replacement for in-game testing. Damage falloff, armor, headshot multipliers, range and missed bursts can change the real outcome. Even so, it is a fast way to compare weapons, scripts, content ideas and practical combat expectations across many FPS games.
