How to use this calculator

What to enter

Enter the values requested in each field: Task start date; Task effort (hours); People assigned; Hours/person/day; Availability %; Working days; Mon; Tue; Wed; Thu; Fri; Sat. Keep time units, work calendars, and currency amounts consistent, and follow any field notes and validation messages.

What the result means

The schedule result estimates a project or task date, duration, working-day count, milestone, or schedule flexibility from the task and calendar values entered. Check the start/end-date convention, workweek, holidays, dependencies, and whether the end date is inclusive.

When to use it

Use this to plan a project schedule or check a target date. Update dependencies and calendars when plans change; actual delivery can be affected by resource constraints, delays, and work that is not represented in the inputs.
