Project timeline template
Updated July 2026 · free template and online tool, no signup to try.
Quick answer
A good project timeline template has one row per task with a start date, a due date, an owner and a %-complete, and it turns those into a visual bar timeline (a mini Gantt) plus an automatic RAG status. You can grab a free Excel version below, or build one instantly in your browser with our online project tracker — both calculate days-left and overall completion for you, with no formulas to write.
What the template contains
| Column | What goes in it | Why it matters |
|---|---|---|
| Task | The deliverable or milestone | One row = one trackable item |
| Owner | Who is accountable | Makes the timeline actionable, not just a chart |
| Start | When work begins | Anchors the left edge of each timeline bar |
| Due | The deadline | Drives days-left and the late/at-risk flag |
| % complete | Progress so far (0–100) | Feeds the RAG status and the roll-up |
| Status | Auto: on track / at risk / late / done | Computed from dates + progress, never guessed |
A timeline is only useful if the status updates itself
Hand-coloured timelines drift out of date the moment a deadline slips. The template and the online tool both recompute each task's RAG status from the dates and progress you enter — so a task that is past due and under 100% turns red on its own, and the overall %-complete rolls up automatically. You maintain the data; the status maintains itself.
