Compare calculators
Both calculators run independently β change the inputs on either side to compare results.
Project Management
Critical Path Duration Calculator
Sum the durations of three sequential tasks to estimate critical-path duration. Use it for very simple linear project sizing or as an introduction to the critical-path concept β for real projects with branching dependencies, use proper CPM software.

Project Management
Resource Utilization Calculator
Calculate resource utilization as the percentage of available hours actually allocated to project work. Use it to identify under- or over-utilization of staff, balance workloads, and optimize team capacity planning.
