Group Work Calculator
What is a Group Work Calculator?
A Group Work Calculator determines how long it takes for multiple people (or machines) working together to complete a task, based on their individual work rates.
Why is a Group Work Calculator Important?
- Helps in workforce planning and team productivity analysis
- Optimizes task allocation in businesses and projects
- Useful in construction, manufacturing, and collaborative projects
How Does It Work?
The formula used is:

Where:
- T = Total time required
- T 1 , T 2 , T 3 , … = Individual times taken by workers
Example:
If Alice takes 4 hours to complete a task and Bob takes 6 hours, their combined rate is:

Together, Alice and Bob finish in 2.4 hours.
