PhD and Thesis Gantt Chart: Timeline Example by Month

By Dr. Ahmed Mortuza Saleque · Updated November 11, 2026 · How we check our content

The short answer

A thesis Gantt chart breaks the degree into overlapping stages: literature review, proposal and ethics, data collection, analysis, papers and writing, then submission. For a 36-month PhD, plan data collection around months 10 to 22 and writing from month 26, and add milestones such as the confirmation review at month 12. For a master thesis, use weeks or months over 4 to 9 months.

A 36-month PhD timeline

Full-time PhD. Stages overlap on purpose: you write while you analyse.

Stage	Months	Length
Literature review	M1–M6	6 months
Research proposal and ethics approval	M4–M8	5 months
Pilot study	M7–M10	4 months
Main data collection	M10–M22	13 months
Data analysis	M18–M28	11 months
Paper 1 writing	M12–M16	5 months
Paper 2 writing	M24–M30	7 months
Thesis writing	M26–M34	9 months
Submission and viva preparation	M34–M36	3 months

Milestones: confirmation review (M12), paper 1 submitted (M16), paper 2 submitted (M30) and thesis submission (M34). This exact plan is the PhD thesis example in the Gantt Chart Maker, so you can load it and change the months.

A 6-month master thesis

Stage	Months
Topic, supervisor meetings and proposal	M1
Literature review	M1–M2
Method and data collection	M2–M4
Analysis	M3–M5
Writing chapters	M3–M6
Final edit, formatting and submission	M6

For a thesis of six months or less, switch the chart to month columns and set the snap to about a week so you can place short tasks precisely.

Rules that keep a thesis plan realistic

Overlap writing with analysis. Theses that start writing only after all analysis is done usually overrun.
Put ethics approval before any data collection bar, and allow 2 to 3 months for it.
Add buffer: about 10% of the total time, placed before submission, not spread thinly.
Mark holidays, teaching duties and conferences. The days off calculator helps count time you will not be working on the thesis.
Update the chart every few months and show it at supervisor meetings. Progress percentages on each bar make slippage obvious.

Make yours from the template

Open the Gantt Chart Maker, choose Paste your plan and load the PhD thesis example.
Edit the lines. Times can be written as M4-M9, as calendar months such as Jan-Jun 2027, or as a length such as 6 months, which starts after the previous task.
Add Milestone:, Deliverable: or Deadline: lines for reviews, papers and submission.
Choose a style (Minimal or Print work well for a thesis appendix) and export a PNG, SVG or PDF.

To turn calendar dates into month numbers, count the months from your start date with the date calculator.

Common questions

How long should each stage of a PhD take?

For a 3-year full-time PhD, a common split is about 6 months of reading and proposal, 12 to 15 months of data collection, a year of analysis overlapping with it, and 8 to 9 months of writing.

Should a thesis Gantt chart use weeks or months?

Months for a PhD, weeks or months for a master or bachelor thesis of under 9 months.

Where does a Gantt chart go in a thesis proposal?

Usually in the timeline or work plan section near the end, or as an appendix if the page limit is tight.

Can I share my thesis timeline with my supervisor?

Yes. Export a PNG or PDF, or use Copy link in the Gantt Chart Maker, which stores the plan in the link itself.
