Tasks · dates · weekly bars

Estimate the plan, then open the Gantt chart

Enter the number of tasks, completed tasks and average duration. The workbook adds owners, dependencies, start dates and a weekly timeline that redraws automatically.

  1. Give every task one accountable owner.
  2. Add dependencies, approvals and nonworking days before sharing dates.
  3. Update progress from completed work and record schedule decisions.

Planning aid only. Count-based progress and task-days do not predict or guarantee a delivery date; dependencies and parallel work matter.

Questions

Is the Gantt template free?

Yes. Fill it in and download Excel without signing up.

Do the bars update automatically?

Yes. Change start date or duration and the weekly conditional-formatting bars redraw.

Can I add more than 20 tasks?

Yes. Insert rows and extend formulas and conditional formatting carefully.

Does percent complete predict the finish date?

No. It is a status input; dependencies, resources and risk still control the schedule.

Are dates calendar or business days?

This simple version uses calendar days. Adapt it if the project requires a workday calendar.
