Productivity Calculator
Turn a count of output and the hours (and workers) it took into a productivity rate — output per hour, per worker, or per worker-hour — or, for service work with no single unit to count, revenue per hour and revenue per dollar of labor. Compare a rate to a previous period, or work out how many hours a target would take.

What labor productivity means
The U.S. Bureau of Labor Statistics defines labor productivity as output divided by hours worked — in its own words, “labor productivity equal to output divided by hours,” a measure of how efficiently hours worked are turned into production (bls.gov). It is a rate, not a total: 1,200 units made in 40 hours is a labor productivity of 30 units per hour, and that rate is what lets a 40-hour week be compared with a 60-hour week, or a four-person crew with a six-person one, on equal footing.
This calculator covers labor productivity two ways. Units of output is the classic version — a count of things produced (parts assembled, orders packed, calls handled) divided by the hours it took, with an optional worker count that splits the rate into output per worker (headcount only, ignoring time) and output per worker-hour (the crew- and time-adjusted figure, output divided by hours times workers). Revenue mode is the practical stand-in when there is no physical unit to count — revenue divided by labor hours, and revenue divided by labor cost, the dollars of output each dollar of wages produced.
Two things worth knowing about the number once you have it. First, a rate has no meaning against another business's rate — a print shop's units per hour and a call center's calls per hour are not comparable, only a rate compared against its own history is. Second, productivity can move opposite to total output whenever hours change faster than output does: fewer hours worked with only a slightly smaller output still shows up as a higher rate, even though less was actually produced.
Worked example, the default numbers above
A four-worker crew produces 1,200 units over a 40-hour week. Output per hour is 1,200 ÷ 40 = 30 units. Output per worker, ignoring hours, is 1,200 ÷ 4 = 300 units. Output per worker-hour — the figure that accounts for both the 40 hours and all 4 workers — is 1,200 ÷ 160 total labor hours = 7.5 units.
If the same crew made 1,120 units in the same 40 hours last week — 28 units an hour — this week's 30 units an hour is a productivity change of +7.14%. And at this week's rate, reaching a target of 1,500 units would take 1,500 ÷ 30 = 50 hours.
The revenue side works the same way: $6,000 of revenue from 150 labor hours is $40 of revenue per hour, and against $3,000 of labor cost for those hours, that's $2 of revenue for every dollar spent on labor.
Output per hour as hours change, at 1,200 units
Holding output fixed at 1,200 units and varying only the hours it took shows the relationship directly: the fewer hours the same output takes, the higher the rate.
| Hours | Output per hour (1,200 units) |
|---|---|
| 20 | 60 |
| 25 | 48 |
| 30 | 40 |
| 35 | 34.29 |
| 40 | 30 |
| 45 | 26.67 |
| 50 | 24 |
| 55 | 21.82 |
| 60 | 20 |
For the hours themselves — a single shift, or a whole week across a crew — the hours-between-times and timesheet calculator pages do the timing this calculator turns into a rate.
Frequently Asked Questions
What's the difference between productivity and efficiency?
Productivity is a rate — output divided by an input, usually hours. Efficiency is a ratio to a maximum — actual output compared with the best possible output from that same input. Two workers can have equal productivity, say 30 units an hour, while one is closer to the physical ceiling for the task and so is more efficient; productivity says how much came out, efficiency says how much was left on the table.
How do I measure "output" for a service business, where there's no physical unit?
Pick a countable stand-in for the work done: calls answered, tickets closed, invoices processed, patients seen, orders fulfilled, rooms cleaned. When no single unit fits the whole job, switch to the revenue mode above — revenue per hour and revenue per dollar of labor — which is the standard substitute for service-sector productivity when output itself resists counting.
Why can productivity rise while total output falls?
Because productivity is a ratio, not a total. If hours worked drop faster than output drops — layoffs, fewer shifts scheduled, a smaller crew doing less but doing it leaner — output per hour goes up even though the business produced less overall. It's a common pattern early in a downturn and one reason a rising productivity number alone isn't good news by itself.
Does adding more workers always raise output per worker-hour?
No. Output per worker-hour only rises if each added worker contributes at least as much as the existing average. On a task that doesn't scale cleanly — one cash register, one delivery truck, one oven — extra people can add total output while each worker-hour produces less, because the added hands are waiting on the bottleneck rather than adding throughput.
What's a "good" productivity number?
There isn't a universal one — it depends entirely on the unit being counted and the industry, so a number from a different business isn't a fair yardstick. What's meaningful is the trend: is this period's rate higher than last period's for the same crew and the same kind of work, which is exactly what the percent-change section above is for.
How is labor productivity different from total factor productivity?
Labor productivity, the figure this calculator produces, only relates output to hours worked. Total factor productivity (TFP) additionally accounts for capital, materials and other inputs, so it isolates gains from technology or better process rather than just working more hours or adding people — see the BLS explainer linked below for the full comparison.
Hours are simple subtraction, breaks are subtracted, decimals are minutes ÷ 60, and rounding follows the FLSA 7-minute rule where you switch it on. Overtime rules here are the federal and California defaults; your state, union contract or employer policy may differ, and pay figures are gross, before tax.
