Fiscal Sponsorship Fees — What's Reasonable?
Fiscal sponsorship fees usually run between 5% and 15% of the funds processed, depending on the model and the depth of service provided. But the headline percentage is the least useful way to compare sponsors. A 6% fee that excludes half the services you need can cost you more than a 9% fee that includes everything.
This page breaks down what drives sponsorship fees, what a reasonable rate includes, and how to compare fees in a way that reflects actual value.
The Typical Range
Across the field, administrative fees generally fall within these bands:
Comprehensive (Model A) sponsorship typically runs 8% to 15%. The sponsor is the legal employer, holds all assets, carries insurance, runs payroll, manages bookkeeping, and assumes full compliance and fiduciary responsibility. The higher rate reflects the depth of what's carried for you.
Pre-Approved Grant (Model C) sponsorship typically runs 3% to 8%. The sponsor receives and regrants funds while your project handles its own operations, so the sponsor's role — and the fee — is narrower.
These are ranges, not rules. A sponsor at the high end of the band may be offering far more service than one at the low end. The rate alone tells you very little without knowing what it covers.
What Drives the Fee
A few factors move a sponsor's rate up or down:
Model. Comprehensive arrangements cost more than regranting arrangements because the sponsor is carrying more — employment, insurance, full bookkeeping, complete compliance.
Service depth. A sponsor offering only core fund processing and compliance charges less than one that also provides grant research and review, legal guidance, fundraising consulting, branding support, and access to a vetted network of providers. More service, higher rate — and often, more value.
Project scale. Many sponsors reduce their rate as a project's revenue grows, since the cost of serving a project doesn't scale linearly with its budget. A project at $1M may pay a lower percentage than a project at $100k.
Project complexity. Work involving employees, insurance-sensitive activity (children, elders, health, travel), international operations, or high transaction volume costs the sponsor more to administer, which can affect the rate.
What the Fee Should Include
This is where founders should focus their attention. A reasonable fee should cover the genuine cost of being a tax-exempt home for your work. At minimum, that means:
Receiving and processing donations and grants
Issuing tax-deductible acknowledgments to donors
Holding and tracking your restricted funds
Annual tax filings (Form 990) and audit coverage
Compliance with federal and state nonprofit requirements
Basic financial reporting
Stronger sponsors include considerably more — bookkeeping, payroll, insurance, HR, grant support, legal and compliance guidance, and access to vetted service providers. When you evaluate a fee, the real question isn't “how high is the percentage” but “what does this percentage actually carry for me, and what would I have to buy separately if it didn't.”
Why the Cheapest Fee Often Isn't the Cheapest
It's tempting to choose the sponsor with the lowest headline rate. But a low fee that excludes services you need shifts those costs onto you — in dollars and in hours.
Consider what a project would otherwise pay for separately: bookkeeping, an annual audit or review, insurance, payroll administration, legal counsel, and the founder time spent managing all of it. For a project under roughly $500k, those costs added together frequently exceed the difference between a low fee and a comprehensive one. The “cheaper” sponsor ends up costing more once you count everything you had to buy or do yourself.
But cost isn't the only reason projects choose sponsorship — and it isn't even the main one for many. Projects with budgets of $1M to $5M regularly choose to stay sponsored, not because they can't afford to run their own back office, but because they don't want to spend the time, attention, or energy on it. Fees decrease at scale, and for a mission-focused team, the peace of mind of having compliance, insurance, banking, and administration handled at an institutional standard is, simply, priceless. The economical question is total cost. The strategic question is what your attention is worth — and where you want it to go.
A Note on Model A vs. Model C Costs
The fee difference between Model A and Model C — often around 3% — looks like a clear savings in favor of Model C. But the comparison isn't that simple.
Under Model C, your project carries its own bookkeeping, insurance, tax filing, and legal costs, plus any tax owed on regranted funds depending on your entity structure. Before choosing Model C to save on the fee, a tax advisor should be engaged to determine whether the taxes owed on grants alone outweigh the roughly 3% difference between Model A and Model C. For some projects, the Model C “savings” disappears once tax exposure and operational costs are counted.
What Reasonable Looks Like
A reasonable fee is transparent, predictable, and proportionate to what's delivered. You should be able to get a clear answer on the headline rate, what's included, what costs extra, and whether the rate decreases at scale. A sponsor that's evasive about fees, charges above roughly 15% without exceptional service to justify it, or buries costs in unexplained add-ons is one to approach carefully.
Holistic Underground
Holistic Underground charges 9% under Model A and 6% under Model C, decreasing at higher revenue levels by negotiation. But the rate is the least interesting part of what HU offers.
Under Model A, the fee covers everything a comprehensive sponsor should — institutional-grade compliance, insurance, payroll, bookkeeping, and full fiduciary coverage — and a great deal that no other sponsor includes:
A mastermind community of like-minded mission leaders
A vetted, trusted network of service providers for branding, financial planning, fundraising, and virtual-assistant hiring
Free fundraising research templates and support
Free sessions with coaches and financial advisors
Technical assistance on call, as needed
A banking platform with full 24/7 transparency into your funds — no emailing to ask where your funds stand
Institutional-grade compliance, insurance, and coverage, delivered with an accessible, community-forward level of service
It's partnership, not transaction.
Under Model C, projects handle their own bookkeeping, but we make it easy — providing simple, ready-to-use templates for bi-annual reporting. Model C projects also get their own bank account with full transparency into their funds, which is rare in regranting relationships. And while some services are reserved for Model A, our Model C projects are still treated as part of the community and receive many of the most important benefits.
This is the difference between a sponsor that processes your funds and a sponsor that stewards your work. If you want to understand what sponsorship would actually cost — and provide — for your project, we'd welcome the conversation.
