eng.cycle-time-efficiency Calculator
Calculates manufacturing cycle time, throughput rate, and efficiency from processing times and WIP counts using Little's Law. Little's Law (WIP = throughput × cycle time) is universal — it applies to any queuing system from manufacturing to hospitals to software development queues.
Inputs
Takt Time Min
Duration of the process. Make sure units match the rate inputs (seconds, minutes, or hours).
Actual Cycle Time Min
Duration of the process. Make sure units match the rate inputs (seconds, minutes, or hours).
Changeover Min
Duration of the process. Make sure units match the rate inputs (seconds, minutes, or hours).
Daily Shifts
Reference formula or conversion factor shown for context.
Results
cycle efficiency
Useful output divided by total input, as a percentage. True 100% efficiency is impossible — losses appear as heat. LEDs: 30–50%. Electric motors: 85–97%. Switching supplies: 85–95%.
