Motivation Letter for PhD: Format & Samples

Did you know? Academic advisors now emphasize that a strong motivation letter should demonstrate “interdisciplinary impact and research adaptability”, with institutions like PhDportal recommending explicit mention of your research contributions, future impact, and alignment with faculty expertise

If you are searching options for doing your research degree abroad, you’ll need a couple of documents and written letters. Out of those, a Motivation letter is considered a very important document when a PhD admission is concerned. It highlights your academic background, research interests and reasons for applying to a doctoral program. 

It typically has a 20-40% weightage in overall PhD admissions, showing its importance. Unlike an SOP (Statement of Purpose), a letter of motivation focuses more on your passions about research and how you align with the university’s ongoing projects or faculty expertise.

In 2025, with PhD acceptance rates as low as 15% in top global universities, a well-crafted motivation letter can set you apart. It should reflect your long-term research vision, previous academic or project achievements, and your fit with the department's goals. Whether you're applying for a PhD in Computer Science, Environmental Science, or Psychology, tailoring the letter to each program’s research focus is key to success.

We’ll explain how to write a motivation letter so your letter feels natural, personal, and convincing. Read the steps of drafting, instructions to follow, mistakes to avoid and practice writing your own using written samples we have provided.
