Grant Sustainability Plan: How to Write the Section Funders Score

A grant sustainability plan is the section of a proposal that explains what will continue after the grant ends, how it will be paid for, and who will make sure it happens. Funders ask for it because they do not want to fund a service that disappears the month their money stops. A credible plan names specific future funding, shows how ongoing costs will change, documents partner commitments, and is honest about anything that will not continue.

What "sustainability" means to a reviewer

Sustainability does not mean every staff position and activity runs forever at full scale. Reviewers are asking whether the benefits last: whether participants keep getting a service, whether a practice stays in place, whether a system change sticks. Some projects sustain through new revenue; others sustain because the grant paid for things that do not need to be paid for again, such as a curriculum, trained staff, or a data system.

That distinction gives you three ways to answer the question:

• Financial: new or redirected revenue covers the ongoing cost.
• Programmatic: the work becomes part of standard operations, with documented procedures and trained staff, so it no longer depends on one grant-funded person.
• Systems or policy: a partner, school district, health system, or government agency adopts the practice, pays for it, or changes a rule so it continues without you carrying it.

The strongest plans use more than one.

What funders actually ask

Read the prompt word for word, because funders frame it differently and score what they ask. Foundation applications often ask some version of "How will this project be sustained after the grant period?" or "What other funding sources are you pursuing?" Federal criteria tend to be more specific. The Department of Education's general selection criteria (34 CFR 75.210), which many of its competitions draw from, include factors such as:

• "The extent to which the proposed project demonstrates that it is designed to build capacity and yield sustainable results that will extend beyond the project period."
• "The extent to which there is a plan to incorporate the project purposes, activities, or benefits into the ongoing work of the applicant beyond the end of the project period."
• Whether the applicant "has the resources to operate the project beyond the project period, including a multiyear financial and operating model and accompanying plan."

When a notice of funding opportunity uses language like this, answer each factor in order, using its wording as your subheadings.

Strategies that hold up

Reduce the recurring cost. Separate one-time costs (curriculum development, equipment, training design, startup staffing) from the annual cost of keeping the program running. If year three costs half of year one, you only have to replace half. This is often the most convincing move in the whole section, because it also argues that the grant buys durable assets.

Diversify revenue, with status for each source. Possible sources include other foundation grants, government contracts, fee-for-service or sliding-scale fees, insurance or Medicaid reimbursement where the service qualifies, corporate sponsorship, individual donors, and a line in your operating budget. For each, state the target amount and where it stands today: in hand, committed, applied, or planned.

Secure partner commitments. Schools, health systems, employers, and agencies can take over space, staff time, referrals, or costs. A signed memorandum of understanding or a letter of support with specific commitments is evidence; a partner's general enthusiasm is not. If partners contribute space or staff time, value it the way our guide to matching funds and in-kind contributions describes.

Embed the work. Cross-train staff, document procedures, and move key functions into existing job descriptions so the program survives a staff departure.

Use your results. Outcome data from your evaluation design is what persuades the next funder. Say how and when you will share it with the prospects you have named.

Plan to scale down if needed. Say which components continue and which end or shrink if a source falls through. A plan where everything continues on less money reads as wishful.

How to write the section

1. Open with the answer. One or two sentences saying what continues, at what annual cost, funded by what mix.
2. Show the cost picture. Grant-period cost versus ongoing annual cost, with the one-time items that fall away.
3. List the sources. A short table with source, amount, and status is clearer than a paragraph.
4. Document partners. Who contributes what, and where the commitment is written down.
5. State what changes. Components that end, shrink, or move to a partner.
6. Name who monitors it. A board committee or executive, a review schedule, and a decision point well before the grant ends.

Length follows the funder's limit. Half a page that names three committed sources is stronger than two pages of intentions. Make sure every figure matches your budget; our guide to separating recurring from one-time costs shows how.
