Rounds per Second (RPS) Calculator
This RPS calculator helps you predict the rate of fire of your AEG. Choose a common gear ratio (13:1, 16:1, 18:1), enter your motor speed or TPA with battery voltage, and instantly see your estimated rounds per second. It’s a great tool for players optimizing their trigger response, balancing rate of fire with reliability, or planning upgrades without trial-and-error.
