What is Cycle Time?
Cycle time is a fundamental metric used in manufacturing, software development, and project management to measure the average time it takes to complete one unit of production or one task from start to finish. Unlike Lead Time, which tracks the entire duration from a customer's order to delivery, Cycle Time focuses strictly on the active production phase. Understanding your cycle time helps identify bottlenecks, improve efficiency, and set realistic production targets.
How to Calculate Cycle Time
The standard formula for calculating cycle time is quite simple: Cycle Time = Total Net Production Time / Number of Units Produced. To use this calculator, simply input the total time spent working (broken down into hours, minutes, and seconds) and the total number of units or tasks completed during that period. The tool will then provide the average duration spent per unit.
Cycle Time vs. Lead Time vs. Takt Time
It is common to confuse these three metrics. Lead Time is the total time a customer waits for an order. Cycle Time is the time it takes to actually build the product. Takt Time is the rate at which you need to complete a product to meet customer demand. By balancing these three, businesses can achieve a "Lean" workflow, minimizing waste and maximizing throughput.
Frequently Asked Questions
No. When calculating cycle time, you should use the "Net Production Time," which excludes scheduled breaks, maintenance downtime, or periods where the production line is inactive.
Increasing cycle times often point to inefficiencies, such as aging machinery, complex task handovers, or a lack of standardized work procedures. Monitoring this trend helps in proactive troubleshooting.
Absolutely. In Agile methodologies, cycle time measures the duration from when a developer starts working on a ticket (In Progress) to when the ticket is marked as Done.
