General operating support and project grants fund nonprofits in very different ways. Learn the pros, cons, and strategy for pursuing each type of grant funding.

Two grants of the same dollar amount can have wildly different value to your organization, depending on a single distinction: what the money is allowed to do.

That distinction is general operating support versus project (or program) grants. It’s one of the most important concepts in grant seeking, and one of the least discussed. Understanding it changes which funders you pursue, how you write your proposals, and how stable your organization actually is.

This guide breaks down both types and how to build a strategy that uses each well.

TL;DR: Quick Answers

What is general operating support? Unrestricted funding the organization can use for any legitimate expense, salaries, rent, programs, whatever the mission needs.
What is a project grant? Restricted funding that can only be spent on a specific, defined project or program.
Which is better? General operating support is more valuable and flexible, but project grants are far more common and often easier to win.
What’s the right strategy? Pursue both deliberately, project grants for their availability, operating support for the stability it brings.

What Is General Operating Support?

General operating support (often called GOS, unrestricted funding, or core support) is grant money given to your organization rather than to a particular project. You can spend it wherever the mission needs it most: staff salaries, rent and utilities, technology, professional development, filling a gap left by a delayed grant.

It’s widely considered the most valuable kind of funding because it’s flexible. It lets leadership direct resources to real priorities instead of forcing every dollar into a pre-defined box. It funds the unglamorous things, like accounting, insurance, and a development director, that keep an organization alive but rarely fit inside a project budget.

The catch: general operating support is harder to find. It requires a funder to trust your organization as a whole, so it tends to come from funders who already know you, or who explicitly believe in core support.

The good news is that the trend is moving in your favor. According to Candid, 40.3% of analyzed foundation grants in 2024 were general operating support, up from 37.1% in 2023. Smaller foundations lead the way, giving unrestricted operating grants 49.4% of the time versus 26.9% for the largest funders, so a local or family foundation is often your best bet for flexible dollars. And Candid found that over half of the grants it tracked in 2025 were general operating support, as foundations increasingly act as a stabilizing force for the sector.

What Is a Project Grant?

A project grant (or program grant) funds a specific, defined initiative. The funder is buying a particular outcome, an after-school program, a new clinic service, a community garden, and the money is restricted to that purpose.

Project grants come with structure: defined goals, a project budget that often can’t be deviated from, frequently a required logic model, and specific reporting on that project’s results.

Project grants are far more common than operating support. Most foundations, government agencies, and corporate giving programs prefer them, because a defined project is easier to evaluate and points to concrete, attributable results.

The Trade-Offs Side by Side

Factor	General Operating Support	Project Grant
Flexibility	High, use anywhere	Low, restricted to the project
Availability	Less common	Very common
Ease of winning	Harder, needs deep trust	Often easier
Builds organizational stability	Strongly	Indirectly
Reporting burden	Usually lighter	Often heavier, project-specific
Funds overhead/core costs	Yes	Only the project’s share

The pattern: operating support is more valuable per dollar, project grants are more available. A strategy built on only one is incomplete.

The Hidden Risk of Living on Project Grants Alone

Many nonprofits, especially newer ones, live entirely on project grants. It’s understandable, they’re what’s available. But an organization funded only by restricted project money carries a real risk: the starvation cycle.

Here’s how it happens. Project grants rarely cover the full cost of core operations, leadership, finance, fundraising, infrastructure. An organization with only project funding chronically underfunds its own backbone. It can’t invest in the systems and staff that would let it grow or even stay healthy. Worse, between projects there’s no flexible money to bridge the gap.

This is why operating support matters beyond convenience: it’s what keeps an organization stable and able to plan. Recognizing this risk is part of building a sound 12-month grant strategy.

How to Pursue Each Type

Winning project grants. These reward a sharp, specific case. Define the project tightly, build a clear logic model, write a compelling statement of need for that specific work, and present a precise budget. Make sure the project’s indirect-cost allowance covers as much real overhead as the funder permits, see our budget guide.

Winning operating support. This rewards organizational trust. Operating-support funders are betting on your whole organization, so emphasize your track record, your impact data, your leadership, and your financial health. Funder research is critical here, identify funders who explicitly offer core or unrestricted support (their 990s and guidelines will say). A strong relationship and a history of good reporting make operating support far more attainable.

A note on framing. When a funder only offers project grants, you can still strengthen your core by defining the “project” to legitimately include the staffing and infrastructure that genuinely drive it, and by claiming the full indirect-cost rate the funder allows.

Build a Balanced Funding Mix

The goal isn’t to pick a side. It’s a deliberate blend:

Project grants for their availability and for funding specific, fundable initiatives. They’ll likely be the larger share, especially early on.
Operating support for the flexibility and stability that let your organization actually function and grow. Build toward this as relationships deepen.
Other revenue, individual giving and fundraising, which is often unrestricted and plays the same stabilizing role as operating support.

As trust with funders grows, some project funders will convert to operating-support funders. That progression, from restricted to unrestricted, is a sign of a maturing, well-stewarded organization.

Find the Right Mix Faster

Knowing you need both kinds of funding is one thing. Finding the specific funders for each, the ones offering unrestricted support and the ones backing projects like yours, is the work.

Grantboost continuously scans funding sources and scores opportunities for fit with your organization, surfacing both project and operating-support opportunities that match your mission. With every opportunity tracked in one pipeline, it’s easy to see whether your funding mix is balanced or dangerously tilted toward restricted money, and to draft funder-aligned proposals for either type in your organization’s voice.

Try Grantboost free and build a funding mix that keeps your organization both funded and stable.
