Compare calculators

Both calculators run independently — change the inputs on either side to compare results.

Critical Path Method Calculator

Estimate the minimum project duration accounting for task dependencies, parallel workstreams, and resource constraints. Useful during project planning to find schedule bottlenecks.

Longest Task Sequence Duration (days)

Sum of All Task Durations (days)

Maximum Parallel Tasks (tasks)

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.

Total Available Hours (hours)

Allocated Hours (hours)
