Stress-Testing Your Fundraising Plan Before It Breaks
Sector-wide guidance often suggests that nonprofits aim for at least four distinct revenue streams, with no single stream making up more than roughly 30% of overall revenue.* It's a useful benchmark, though not a hard rule, since the right mix depends entirely on what your organization does and who supports it. But the underlying principle holds regardless of your specific numbers: diversification is what gives an organization the ability to weather a funding disruption without everything else falling apart along with it.
Once you understand your current mix, though, there's a second, less obvious layer worth paying attention to: not just how much money you're bringing in, but what kind of money it is, and what that means for how you can actually use it.
Three dimensions worth understanding
Restricted versus unrestricted. If you receive $100,000 as a grant, but $90,000 of it is restricted to a specific program while you have $20,000 in unrestricted expenses to cover just to keep the lights on, that grant doesn't solve your whole problem, even though it looks like a big win on paper. Unrestricted revenue matters not because it's inherently better, but because it gives you flexibility to direct funds wherever they're needed most. This is part of why earned income (consulting fees, membership dues, training programs, ticket sales) can be so valuable, even at a modest scale: it's almost always unrestricted, and it's revenue you have real control over.
One-time versus recurring. A gala that raises $50,000 is a genuine win, but it requires replicating that effort, from scratch, every single year. Two hundred donors giving $20 a month adds up to a similar annual total, but it's dramatically more predictable, and it builds relationships over time instead of resetting to zero each year. Neither approach is wrong; events serve real purposes beyond just the dollars raised, including visibility and community-building. But it's worth being honest about which direction your mix currently leans.
Predictable versus variable. A guaranteed multi-year contract behaves very differently, from a planning standpoint, than an annual event whose proceeds might range widely year to year. Both types of revenue have their place, but leaning too heavily on variable income makes it genuinely harder to plan ahead, whether that's deciding when to hire, when to pilot a new program, or when to commit to new ongoing expenses.
There's no perfect mix, only a better one
It's tempting to imagine an ideal, evenly balanced revenue pie: a quarter from individuals, a quarter from grants, a quarter earned, a quarter corporate. In practice, that rarely makes sense for any real organization. What you're actually aiming for is a mix that gives you enough flexibility to respond to changing needs, enough predictability to plan responsibly, and enough balance that no single funder or event has the power to derail your organization if something shifts.
The goal isn't to overhaul your entire funding model in one fiscal year. It's to make one deliberate, strategic move that leaves your organization a bit stronger and a bit less vulnerable than it was last year.
If you're currently dependent on one major foundation, you don't need to replace that relationship overnight, but you might commit to cultivating three new institutional relationships this year, so you have real options developing for the year after. If most of your funding is restricted, you might set a specific unrestricted individual giving goal to gradually build in flexibility. If you're leaning heavily on one annual event, you might start building a recurring donor program alongside it, not to replace the event, but to balance it. If you have no earned income at all, that's completely fine; a small, low-risk pilot is a reasonable place to start, just to learn what works. And if your individual giving program is still young, focusing first on retaining and deepening the relationships you already have is often more effective than chasing a wave of brand-new donors.
Monitoring and adjusting throughout the year
A development plan is a living document, not something you set once and revisit twelve months later. Build in regular check-ins, even brief ones, to ask a few honest questions: Are we tracking toward our goals? What's working better than expected? What's proving harder than we planned for? Has anything changed, whether in the funding landscape, our own capacity, or our organization's priorities, that means the plan needs to adjust?
This kind of ongoing evaluation isn't a sign that the original plan was flawed. It's simply how sustainable organizations operate: setting a direction, moving toward it, and staying honest about what the data and the day-to-day reality are actually telling you along the way. Sector-wide funding conditions shift, sometimes significantly and with little warning, which makes this kind of periodic reflection even more valuable; a plan that's flexible enough to absorb a disruption is far more resilient than one that assumes conditions will stay constant.
What to watch for as warning signs
A few patterns are worth flagging early, before they become a crisis. If a single funder or a single event makes up the majority of your annual revenue, that's a signal worth taking seriously, even if things feel stable right now. If your team finds itself constantly in short-term, reactive fundraising mode, chasing whatever deadline or emergency is most immediate, that's often a sign that medium and long-term relationship-building has quietly fallen off the priority list, even though it's usually what creates the most stability over time. And if your reporting or financial systems don't clearly show you the breakdown of restricted versus unrestricted funds, that's worth fixing sooner rather than later, since it directly affects how confidently you can plan and budget.
None of these signs mean something has gone wrong. They're simply useful indicators that it might be time to make one of those incremental, intentional shifts discussed above, before a funding change forces the issue.
The takeaway
Balancing your fundraising mix isn't about hitting a perfect formula. It's about understanding, in real terms, what kind of revenue you're bringing in, staying honest about where you're vulnerable, and making incremental, intentional moves toward greater flexibility and resilience each year. Small, deliberate steps compound. A stronger mix next year doesn't require reinventing your entire fundraising program this year, just one thoughtful, well-chosen shift at a time.
In community, The Mockingbird Team
Sector-wide funding conditions have real, uneven effects across the nonprofit world. Organizations respond in a variety of ways: refreshing strategy to meet the moment, moving faster on private fundraising, building local resource-sharing networks and coalitions with peer organizations, and diversifying revenue through earned income, membership models, or corporate partnerships. There's no single right response, but organizations that stay proactive about diversification tend to weather disruption with more stability than those that don't.
