Calculate Cycle Time Formulas
What is the Cycle Time Formula?
The Cycle Time Formula is an essential manufacturing KPI to understand in manufacturing. It is used by ERP and MES systems for scheduling, purchasing and
(Don’t get Cycle Time confused with Takt Time, though, which is a pretty common mistake.)
Cycle Time: This is how long it takes to make a part or how long it takes the machine to complete a cycle. Some machines produce multiple parts per cycle while
Cycle Time Measurements
Cycle times can be expressed in many different units of measure below are a few of the most common and what you find in many manufacturing analytics systems like SensrTrx.
- Parts per Minute
- Minutes per Part
- Seconds per Part
- Parts per Second
- Hours per Part
- Parts per Hour
We will show you how to calculate cycle time in any of the above units and how to convert it, too. From the list above, it may seem like there are 6 different formulas but there are really only 2:
- Parts per Time Period
- Time Period per Part
There are two components of the formula:
Total Parts Produced: Including scrap and good parts
Production Run Time: How long the machine running when the parts are produced (Do not include planned or unplanned downtime)
Parts per Time Period Cycle Time Formula
Total Parts Produced / Production Run Time = Actual Cycle Time (parts/min)
Parts per Time Period Cycle Time Calculation:
10 parts/min = 1,200 parts / 120 minutes
How To Do Cycle Time Formula in Excel
How would you calculate cycle time formula in Excel or Google Sheets?
Cell A-24 = # of parts
Cell B-24 = Minutes of production run
Formula = (=A24/B24)
Time Period per Part Cycle Time Formula
This formula is useful with longer cycle times like 30 minutes per part (which is the same as 2 parts per hour, but more on that later).
Time Period per Part Cycle Time Calculation:
30 minutes/part = 120 minutes / 4 parts
Cycle Time Conversions
Often, you will need to convert cycle times into another unit of measure. You can use the list below as a cheat sheet to convert the various formulas into parts per minute.
Minutes per Part
1 / Minutes per Part = Parts per Minute
Seconds per Part
(1 / Seconds per Part) * 60 = Parts per Minute
Parts per Second
Parts per Second * 60 = Parts per Minute
Hours per Part
(1 / Hours per Part) / 60 = Parts per Minute
Parts per Hour
Parts per Hour / 60 = Parts per Minute
