Productivity Formula
There isn’t a single universal productivity equation. Depending on whether you’re tracking units, revenue, labor-hours, or progress against a target, you’ll use a variant of Output ÷ Input. This quick reference summarizes the core options.
Productivity = Output ÷ Input. For example, if a team completes 120 units in 10 hours, productivity is 12 units per hour.

Result: 12 units per hour
Need a quick answer? Use the calculator above. If you’re building a report, start with Output ÷ Input, then choose the input that matches your goal (hours, labor cost, or total cost).
Core Definition
Productivity = Output ÷ Input (time or labor-hours). If you produce 120 units in 10 hours, productivity is 12 units per hour.
The core productivity formula
Start with: Productivity = Output ÷ Input. Output is what you produce. Input is the resource you used (time or cost). The best input depends on what you’re trying to improve.
Labor productivity formula
Labor productivity = Output ÷ Labor Hours (or Output ÷ Labor Cost).
Example: If a team completes 120 units in 40 hours, labor productivity = 120 ÷ 40 = 3 units/hour.
Worked example: a five-person team over one week
- Add the labor hours. Five people at 38 paid hours each = 190 labor-hours.
- Subtract hours that produced no output, if you are measuring only productive time. Twenty hours of training and paid leave leaves 170 labor-hours.
- Total the output. The team completed 1,020 units.
- Divide. 1,020 ÷ 170 = 6 units per labor-hour.
Using the unadjusted 190 hours instead gives 5.37 units per labor-hour. Both numbers are defensible; what matters is that you use the same denominator every period, or the trend is meaningless.
Labor productivity by cost instead of hours
When people are paid at different rates, hours flatten a real difference. Swap the denominator: if that same 1,020 units cost $6,800 in wages, labor productivity is 1,020 ÷ 6,800 = 0.15 units per dollar, or inverted, $6.67 of labor per unit. Cost-based labor productivity is the version to use when comparing teams with different skill mixes.
Productivity percentage
If you have a target, use Productivity % = (Actual ÷ Target) × 100.
Example: Actual output 92 vs target 100 → (92 ÷ 100) × 100 = 92%. For more detail, see the productivity percentage guide.
Multifactor productivity (when labor hours isn’t enough)
Multifactor productivity compares output to multiple inputs (often labor + materials + energy). Use it when labor hours stays flat but costs rise, or when material usage is a major driver.
What to use as “output”
- Units produced
- Visits completed
- Tickets closed
- Revenue (when appropriate)
- Standardized ‘points’ (when tasks vary)
Common mistakes (and how to avoid them)
- Changing what “output” means between months → pick a definition and keep it stable.
- Mixing minutes and hours → convert to one unit.
- Ignoring quality → track rework/defects alongside productivity.

FAQ
What is the labor productivity formula?
Labor productivity = Output ÷ Labor-hours. Example: 240 units ÷ 20 labor-hours = 12 units per labor-hour.
How do I calculate productivity as a percentage?
Productivity % = (Actual output ÷ Target output) × 100%. Example: 92 ÷ 100 = 92%.
What if my “input” isn’t hours?
You can use other inputs like employees, cost, or machine time—just keep the units consistent.
What is a productivity calculation, in one sentence?
A productivity calculation divides what you produced by what it took to produce it. Everything else — units per hour, revenue per hour, percent of target — is that one division with different things on each side of it.
How do you calculate labor productivity for a team?
Add every person's hours into one denominator, total the team's output, and divide. Five people at 38 hours is 190 labor-hours; 1,020 units ÷ 190 = 5.37 units per labor-hour. Decide once whether training and leave hours count, then keep that choice every period.
Why is my productivity number different from a coworker's?
Almost always the denominator. Paid hours, scheduled hours, and productive hours give three different answers from the same output. Compare the inputs before you compare the results.
Common Variants
- Units per hour: Output units ÷ total hours worked.
- Units per labor-hour: Output units ÷ combined labor-hours across a team.
- Revenue per hour: Revenue ÷ hours worked or billed.
- % productivity vs target: (Actual output ÷ Target output) × 100.
