Takt Time, Cycle Time & OEE Calculator

Compute takt time and the three OEE components (availability, performance, quality) from production shift data — the standard lean-manufacturing KPIs.

Available time (min/shift)

Customer demand (units/shift)

Good units produced

Total units produced

Planned downtime (min)

Actual runtime (min)

How to Use the Takt Time, Cycle Time & OEE Calculator

Enter the available time and customer demand per shift.
Enter total and good units produced.
Enter planned downtime and actual runtime.
Click Calculate.

使用场景

•Lean manufacturing KPIs.
•Bottleneck analysis.
•Shop-floor continuous improvement.

公式

Takt = available time / demand. Availability = runtime / (available − planned downtime). Quality = good / total. OEE = A × P × Q.

常见问题

What is a "world-class" OEE?

The Nakajima benchmark is 85% (A 90% × P 95% × Q 99.9%). Many discrete-manufacturing plants run at 40–60%, so the upside is large.

How is performance defined here?

Performance = (ideal cycle × total units) / runtime. With runtime = ideal cycle × total, the ratio caps at 100%. Feed your own ideal cycle if you track it explicitly.
