Project timeline template

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

DueThe deadlineDrives days-left and the late/at-risk flag

StatusAuto: on track / at risk / late / doneComputed 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Hand-coloured timelines drift out of date the moment a deadline slips.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.
