5 min readHow to write a letter of inquiry (LOI) for a grant
The short letter many foundations ask for first: what to include, how long to make it, and a simple outline.
Many foundations want a short letter before they will read a full proposal. A good one is clear, specific and easy to say yes to.
A simple outline
- Opening. Say who you are and what you are asking for in two sentences, including the amount and the purpose.
- The need. Who is affected, where, and one or two facts you can source.
- Your plan. What you will do, for whom, and over what period.
- Results. What will change, and how you will know. Use numbers you can report on.
- Your organization. Mission, track record and why you are the right group to do this.
- The budget. The total cost, what you are requesting and where the rest comes from.
- Close. Thank them, offer to send more and give a contact name, phone and email.
Tips that help
- Use the funder's own words from their guidelines, and match their priorities honestly.
- Keep paragraphs short. Skip jargon and long histories.
- Follow their format and word limit exactly.
- Have someone outside your organization read it. If they cannot explain it back, rewrite it.
- Do not send the same letter to every funder. Change the opening and the match.
An invitation to apply is not a promise of funding, but it is a good sign. FundLuma's Document Studio can help you produce a first draft that you review and edit.
Common questions
What is a letter of inquiry?
A letter of inquiry is a short introduction to a funder, usually one to two pages. It describes your organization, the need, your plan and what you are asking for, so the funder can decide whether to invite a full application.
How long should a letter of inquiry be?
Follow the funder's limit. If none is given, aim for one page, and two at most.
Do I always need a letter of inquiry?
No. Some funders go straight to an application and others accept only invited proposals. Read the guidelines before you write.
