Productivity Calculator

How to use the productivity calculator

Fill in the three boxes with figures for one period (a shift, a week, a quarter, a project):

• Work hours: the total hours the work took, added up across everyone involved. Ten people working eight hours is 80 hours. Leave it empty and an eight-hour day is assumed.
• Employees: the number of people (or machines) that did the work. Leave it empty or at zero to skip the per-employee figure.
• Revenue: the value of what was produced in that time, in dollars.

The results are revenue per hour of work and revenue per employee. You can swap revenue for any other output measure, such as units made or tickets closed; the arithmetic is identical, only the dollar sign no longer applies.

The productivity formula

Productivity compares what you get out with what you put in. For labor, the input is working time or headcount:

labor productivity = output ÷ hours worked

output per employee = output ÷ number of employees

Output can be physical (units, kilograms, kilometres driven) or monetary (net sales, value added). Physical units are best when the product is uniform; money is better when you need to compare different products or services on one scale.

Worked examples

A bakery shift. Six bakers work eight hours each and the shop takes $5,400 from what they produced. Total hours are 6 × 8 = 48, so productivity is 5,400 ÷ 48 = $112.50 per hour. Per person, that is 5,400 ÷ 6 = $900 per employee.

Comparing two teams. Team A has 12 workers at 40 hours a week (480 hours) and packs 9,600 units: 9,600 ÷ 480 = 20 units per hour. Team B has 9 workers at 38 hours (342 hours) and packs 7,866 units: 7,866 ÷ 342 = 23 units per hour. Team A produces more in total, yet team B is more productive per hour worked.

Growth over time. If revenue per hour rose from $95 last year to $104.50 this year, productivity grew by (104.50 − 95) ÷ 95 × 100 = 10%. Use the percentage calculator for this step.

Worker productivity versus machine productivity

The same formula covers machines: replace employees with the number of machines and hours with machine-hours. A line that fills 150 bottles an hour compared with a hand-filling worker at 18 bottles an hour makes the gain from automation easy to see, as long as you remember to count the cost of the machine.

Labor productivity says nothing about how hard people work. It rises when better tools, training, layout or software let the same hours produce more, and it falls when hours are spent waiting for materials or rework. Treat it as a signal to investigate, not as a measure of individual effort.

Limits and common mistakes

• Mixing periods. Hours, headcount and revenue must cover the same period. Annual revenue with weekly hours gives meaningless numbers.
• Counting only some hours. Include overtime and part-time hours, or productivity will look better than it is.
• Using revenue when prices change. If prices rise, revenue per hour rises even if nothing more is made. Compare units, or adjust revenue for price changes, when you track trends.
• Ignoring other inputs. Labor productivity leaves out capital, materials and energy. A firm can raise output per hour by spending heavily on equipment while total efficiency does not improve.

To judge whether the output covers your costs, pair productivity with a profitability view such as the margin calculator or the break-even calculator.
