Productivity Calculator

Productivity calculator works out Throughput and Average time per unit produced from Units completed, Time taken and Cycle time of each station (optional). The default figures on this page give throughput of 10.000000; change any entry and the result, the working and the sources update together.

Throughput
10.000000
Throughput & Bottleneck Calculator
Average time per unit produced
0.100000
Worked out from Researched engineering contract R3702: throughput = units / time and 2 other sources.
No station cycle times were given, so no bottleneck was identified - only the observed throughput.

Your figures

Updates as you type
In whatever time unit you want the throughput expressed in - hours, minutes or shifts.
Enter the cycle times in station order to find the bottleneck. Same time unit throughout.
Used with the demand below to give the takt time.

How this is worked out

3 steps
  1. Throughput = 100 units / 10 = 10 units per unit of time.
  2. No station cycle times given.
  3. No takt time: give both the available time and the demand.

What the productivity calculator calculates

Computes throughput as completed units over elapsed time, and finds the bottleneck station on a line of stations in series along with the line capacity, the balance efficiency and the idle time at every other station.

How to use this productivity calculator

Enter Units completed, Time taken, Cycle time of each station (optional) and Time available for production. Throughput updates as you type, and “Use a worked example” loads checked figures you can adjust. Change one figure at a time to see what drives the result.

How the result is worked out

Open “How this is worked out” beside the result for the step-by-step calculation behind Throughput, Average time per unit produced and Bottleneck station number.

The method follows Researched engineering contract R3702: throughput = units / time, Goldratt, E.M. (1984), The Goal: An Ongoing Process of Improvement and Hopp, W.J. & Spearman, M.L., Factory Physics.

Research fixture R3702-GT-1: 100 units in 10 hours example

With Units completed: 100, Time taken: 10, the calculator returns Throughput: 10, Average time per unit produced: 0.1. This example is checked against an independent source in the test suite.

What you can compare

Change one input at a time to see how it affects Throughput, Average time per unit produced and Bottleneck station number. The inputs you can vary are Units completed, Time taken, Cycle time of each station (optional), Time available for production and Units of demand in that time.

Frequently asked questions

How do you calculate productivity?

Computes throughput as completed units over elapsed time, and finds the bottleneck station on a line of stations in series along with the line capacity, the balance efficiency and the idle time at every other station. Open “How this is worked out” beside the result to see each step for your own figures.

How do I calculate productivity hours?

It needs Units completed, Time taken, Cycle time of each station (optional), Time available for production and Units of demand in that time. Nothing else is required, and the figures stay in your browser.

What is the formula for calculating productivity rate?

Computes throughput as completed units over elapsed time, and finds the bottleneck station on a line of stations in series along with the line capacity, the balance efficiency and the idle time at every other station. On this page it is computed from Units completed, Time taken and Cycle time of each station (optional) and shown as Throughput, Average time per unit produced and Bottleneck station number.

How do I calculate my productivity in therapy?

The result gives Throughput, Average time per unit produced, Bottleneck station number, Cycle time of the bottleneck, Line capacity set by the bottleneck and Line balance efficiency, each labelled with its unit so the figure can be read on its own.

What information do I need for the productivity calculator?

You need Units completed, Time taken, Cycle time of each station (optional), Time available for production and Units of demand in that time. The page opens with default figures that give throughput of 10.000000, so you can see the scale before entering your own.

What does this productivity calculator show?

It shows Throughput, Average time per unit produced, Bottleneck station number, Cycle time of the bottleneck, Line capacity set by the bottleneck, Line balance efficiency, Idle time per unit across the other stations and Takt time, with the working and any warnings for your entries.
