How to Know If Your Nonprofit Is Too Dependent on Grants

Here's the direct answer, because you came here for it: if any single funding source, one grant, one government contract, one foundation, makes up more than 30 percent of your total revenue, financial advisors and CPA firms who work with nonprofits generally consider that a material risk worth a formal conversation with your board. Cross 40 percent, and most would call it significant concentration risk: the kind that shows up in an audit letter, not just a casual observation.

That's the fast version. It's also incomplete, which is the part almost nobody tells you.

Do the math before you guess

You don't need an accountant to calculate this. Pull your most recent audited financials or your year-end revenue summary and run one formula:

Revenue from your largest single source ÷ Total annual revenue = Your concentration ratio

If a $600,000 nonprofit receives $220,000 from one government contract, that's a 37 percent concentration ratio. Comfortably inside "worth watching," edging toward "worth addressing."

Run it again for your top two or three sources combined. This is where most organizations get an unpleasant surprise. Individually, no single grant looks alarming. Added together, two foundation grants and one government contract can easily account for 65 or 70 percent of a budget, and that combined number is often the more honest picture of your actual exposure.

Concentration is only one piece of the risk

A single ratio makes a clean headline, but nonprofit finance advisors who specialize in funding risk typically look at three other factors alongside it, and skipping them is how organizations end up with a false sense of security.

Restriction. A grant that covers 30 percent of your budget but comes with heavy restrictions on how it can be spent is riskier than an unrestricted gift of the same size. Strong total revenue means very little if most of it can't touch payroll or rent.

Timing. Reimbursement-based grants, where you spend the money first and get repaid later, create cash flow strain that a simple revenue percentage doesn't capture. A government contract can be fully "secured" on paper and still leave you unable to make payroll in a lean month.

Reserves. This is the factor that determines whether concentration is dangerous or just noticeable. The standard benchmark cited across the sector is three to six months of operating expenses held in reserve. National surveys of nonprofit finances have repeatedly found that roughly half of nonprofits hold three months of cash or less, and a meaningful share hold closer to one month. An organization with 40 percent concentration and eight months of reserves is in a fundamentally different position than one with the same concentration and three weeks of cash on hand.

Put those four together, concentration, restriction, timing, and reserves, and you get something closer to an actual risk profile instead of a single number that only tells part of the story.

The nuance most advice on this topic leaves out

Here's where conventional wisdom gets it slightly wrong, and it's worth sitting with for a second before you panic about your own ratio.

Research from the Bridgespan Group, which has spent years studying how nonprofits grow to significant scale, has found something counterintuitive: the overwhelming majority of large, well-established nonprofits are highly concentrated in one dominant revenue category, often well above 60 percent. These aren't fragile organizations. Many of them are the most financially stable in the sector.

Concentration by itself is not the villain. Plenty of well-run organizations are deeply concentrated by design, because they've built deep expertise serving one type of funder and deliberately chosen depth over a scattered fundraising strategy that spreads staff time too thin to do any one thing well.

The actual danger shows up when concentration is paired with thin reserves and a short renewal runway, not when concentration exists on its own. A nonprofit with 70 percent of its revenue from a single government contract that renews on a rolling five-year cycle, backed by six months of reserves, is in a fundamentally different position than one with 35 percent from a single foundation grant that's up for renewal in four months, sitting on three weeks of cash. The second organization has a lower concentration ratio and a much worse actual risk profile.

This is the piece that a single percentage can't show you, and it's the piece worth understanding before you make any decisions based on concentration alone.

Five signs you're carrying more risk than your revenue numbers suggest

You're likely more exposed than your topline revenue makes it look if:

• Your top one to three sources combine for more than 50 percent of total revenue, even if no single source crosses 30 percent alone
• More than half of your revenue is restricted to specific programs rather than available for general operations
• Any major source pays on a reimbursement basis and you're regularly waiting 60 or more days to be repaid
• Your reserves would cover less than three months of operating expenses if a major funder didn't renew
• You genuinely don't know when your largest grants are up for renewal without checking

One or two of these on their own are manageable. Three or more, especially in combination with a concentration ratio above 30 percent, is the point where a formal board conversation stops being optional.

What to actually do with this number

Knowing your ratio is diagnostic, not a plan. If your numbers put you in risk territory, the two moves that matter most, in order, are building reserves before you build new revenue streams, and starting any diversification effort small and adjacent to what you already do well rather than chasing an unrelated, unfamiliar funding source because it looks stable from the outside.

Neither of those is a quick fix. Both are more reliable than the alternative, which is finding out your real number during a funding crisis instead of before one.
