Calculate hours per unit from total hours and units produced, plus units per hour, takt time from demand, and direct labor cost per unit.

Use the same time basis and production period.

Elapsed production hours or summed person-hours: keep the basis consistent.

Hours Per Unit Formula

The following formula is used to calculate the hours per unit for a given total time in hours and number of units produced.

H = T / U

Variables:

  • H is the hours per unit
  • T is the total hours worked
  • U is the number of units produced

To calculate hours per unit, divide total hours by output. Keep elapsed production hours or summed person-hours consistent. Units per hour is the reciprocal for positive output. Takt time divides net available production time by demand over the same period. Direct labor cost multiplies elapsed crew hours per unit by the rate per worker and crew size; do not apply crew size again to summed person-hours.

What is Hours Per Unit?

Hours per unit is a measure of productivity that indicates the amount of time required to produce a single unit of output. This metric is commonly used in manufacturing and production environments to assess efficiency and identify areas for improvement. By understanding the hours per unit, businesses can optimize their processes, reduce labor costs, and increase overall productivity.

How to Calculate Hours Per Unit?

The following steps outline how to calculate the Hours Per Unit.


  1. First, determine the total hours worked (T).
  2. Next, determine the number of units produced (U).
  3. Finally, calculate the hours per unit using the formula H = T / U.
  4. After inserting the values and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Total hours worked (T) = 40 hours; output U = 10 units gives H = 40 / 10 = 4 hours per unit.

Number of units produced (U) = 10
