UPH and UPPH calculator
Units per hour (UPH) measures the output of a line or cell; units per person per hour (UPPH) divides it by headcount so lines of different sizes can be compared. Enter one shift of data to get both, plus the staffing needed for a target.
Result
- UPH (units per hour)
- 150
- UPPH (units per person per hour)
- 15
- Line time per unit
- 24 s
- Units per minute
- 2.5
How to use this tool
- Enter the units completed and the hours the line ran, excluding breaks and planned stops.
- Enter the number of operators. UPH and UPPH appear instantly.
- Enter a target UPH to see the achievement rate and how many people the target needs at the current UPPH.
Good to know
- UPH is computed on the hours entered, so a 7.5-hour shift gives a higher UPH than the same output over 8 hours.
Frequently asked questions
What is the difference between UPH and UPPH?
UPH is units per hour for the whole line, so it rises when you add people. UPPH divides UPH by the headcount, giving the output each operator contributes per hour, which is why it is the figure used to compare lines, shifts and plants of different sizes and to set labour standards.
How do I work out the headcount for a target UPH?
Divide the target UPH by the current UPPH and round up. A line making 1,200 units in 8 hours with 10 people runs at 150 UPH and 15 UPPH, so a target of 200 UPH needs 200 ÷ 15 = 13.3, which rounds up to 14 operators if the per-person rate stays the same.
Should breaks be included in the hours?
Use the hours the line was scheduled to run after breaks when you want a rate that reflects the work pace, which is the usual UPH convention. Include breaks only when you report capacity per paid hour, and label the figure clearly so it is not compared with pace-based UPH.
