Quick answer: An internal cover letter (or letter of interest for an internal position) is a short, one-page letter telling your employer you want a specific role or promotion within the company. Open by naming the role and your current position, highlight measurable results from your time there, show you understand the team's goals, and close with thanks and a request to talk. Keep it to about 200–350 words, since the reader may already know you.
Applying for a job at your own company feels like it should be easy. They already know you. They know your work. They have seen you microwave fish in the break room (we are choosing to forgive you).
But here is the twist: you may still be competing with outside candidates, and the hiring manager might not know your work as well as you think. A strong internal position cover letter fixes that.
Below you will find what to include, how it differs from a regular cover letter, and letter of interest for internal position examples you can adapt today.
What Is a Letter of Interest for an Internal Position?
A letter of interest (sometimes called an expression of interest) is a letter you send to express interest in a role within your current organization. People use it in two situations:
- A posted internal opening. Here it works like a cover letter: you are applying for a specific, advertised role.
- No posted opening yet. You are telling your manager or another department head that you would like to be considered for a type of role, promotion, or team when an opportunity comes up.
Either way, the goal is to turn "the person who sits near the printer" into "the obvious choice for this role."
How an Internal Cover Letter Differs From a Regular One
A standard cover letter introduces a stranger. An internal one builds on a relationship that already exists. That changes a few things:
- Skip the formal introduction. No need to explain who you are from scratch. Lead with your current role, team, and time at the company.
- Use insider knowledge. You understand the company's goals, products, and culture. Show it.
- Proof beats promises. Your achievements can be verified by colleagues, so be accurate and specific.
- Focus on growth, not pay. Frame the move around development and contribution. Salary conversations come later; our salary negotiation guide helps when they do.
- Stay professional. Even if you know the hiring manager well, write a real application.
What to Include in a Cover Letter for Internal Promotion
1. The role and your interest
Name the exact position in your first sentence, and tie your interest to your long-term career goals.
2. Your current role and tenure
State your title, department, and how long you have been with the company.
3. Measurable achievements
Pick two or three results relevant to the new role, with numbers where possible. If you need help phrasing them, see our guide to resume bullet points that show results.
4. How you have grown
New skills, stretch projects, and cross-team work all prove you are ready for more.
5. Your understanding of the team's goals
Explain how you would help the department or company hit its priorities. This is where insider knowledge shines.
6. A referral or supporter (optional)
If a supervisor or senior colleague supports your move, mention them, with their permission.
7. Gratitude and a clear close
Thank the reader and your current team, then ask for a conversation. For closing lines, see our guide on how to end a cover letter.

Tips for using the template:
- Keep it to 200–350 words. An internal cover letter can be shorter than an external one. See how long should a cover letter be
- Only mention your manager's support if they've actually agreed
- Match the format your company uses: an attached letter, an email, or the internal job portal
Before You Send It: Tell Your Manager
(Switches to serious face.) In most companies, your current manager should hear about your internal application from you, not from HR or the hiring manager. Some organizations even require manager approval or notification before you apply internally, so check your internal job posting policy.
Keep it positive: explain why the role excites you and reassure them about your handover. A supportive manager can become your strongest reference.
Tips to Make Your Internal Letter Stand Out
- Keep it to one page, three or four paragraphs.
- Address a real person, not "To Whom It May Concern."
- Be specific. "Improved processes" is vague. "Cut invoice processing time from five days to two" is memorable.
- Do not trash your current team. You still work there, and people talk.
- Update your resume too. Show your progression clearly; our guide on how to show a promotion on your resume explains how.
- Proofread. Your colleagues will notice a typo.
Frequently Asked Questions
Do I need a cover letter for an internal position?
Often yes, even if it is optional. A cover letter or letter of interest shows effort, explains why you want the move, and highlights achievements the hiring manager may not know about. It also helps you stand out against external candidates.
What is the difference between a letter of interest and a cover letter?
A cover letter usually responds to a specific posted job. A letter of interest can do the same, but it is also used when no role is posted, to express interest in a type of position or team. For internal moves, people often use the terms interchangeably.
Should I tell my manager before applying for an internal job?
In most cases, yes. Telling your manager first is respectful and avoids awkward surprises. Some companies require it, so check your internal mobility or job posting policy.
Who should I address an internal letter of interest to?
Address it to the hiring manager for the role. If you are not sure who that is, ask HR or check the internal job posting. Avoid generic greetings when you can easily find the right name.
How long should an internal cover letter be?
About 200–350 words, or three short paragraphs. The reader may already know you, so focus on your achievements and why you want this role rather than a full introduction.
Should I mention salary in an internal cover letter?
No. Focus on growth, contribution, and why you are ready for the role. Discuss compensation later in the process, once there is mutual interest.
