Project Management
Earned Value Calculator
Calculate the Cost Variance (CV) for a project as Earned Value minus Actual Cost, where Earned Value = Budget At Completion × Percent Complete. Use it to determine whether you are over or under budget for the work completed to date — a more meaningful metric than simple actual-vs-planned spend.

Project Management
Project Duration Calculator
Estimate total project duration in days by dividing total work (tasks × average duration) by the number of tasks that can run in parallel. Use it for rough early-stage project planning, capacity-vs-deadline checks, or sprint capacity estimation in agile teams.
