Donor-Advised Funds vs. GivingTuesday: Which Fundraising Idea Actually Moves the Needle?

Imagine You're a Development Director

Imagine you're a development director at a mid-sized nonprofit. It's January, and your board wants a fundraising strategy for the year. Your inbox has two promising ideas: set up a donor-advised fund (DAF) program or plan a big GivingTuesday push. Both sound good, but you have limited staff and budget. Which one actually moves the needle?

As practitioners, we've seen the hype around both. DAFs are growing fast, and GivingTuesday has become a global phenomenon. But the numbers tell a more nuanced story. Let's break down the two options on the criteria that matter: reach, donor engagement, cost, and long-term giving behavior.

The Case for Donor-Advised Funds

DAFs are like charitable savings accounts: donors contribute, get an immediate tax deduction, and then recommend grants over time. The industry is booming. Total assets in DAFs reached $327.87 billion in FY2024, up 27.9% from the previous year, with grants of $64.60 billion, up 17.9% (DAF Research Collaborative). That's a lot of money flowing to charities.

But here's the catch: DAFs are primarily a vehicle for affluent donors. The average DAF account size is $91,300 (DAF Research Collaborative), which means most DAF donors are wealthy. If your nonprofit relies on a broad base of small donors, DAFs might not be your primary channel. However, if you have major donors who are already using DAFs, it's worth engaging them. And note that two-thirds of National Philanthropic Trust grants are unrestricted (up 72% from the prior year), which is great for charities because unrestricted funds give you flexibility (National Philanthropic Trust).

The Case for GivingTuesday

GivingTuesday is the opposite: it's a mass participation event. In 2024, it raised an estimated $3.6 billion in the U.S., up 16% from 2023, with 36.1 million participants, including 18.5 million who made financial donations (GivingTuesday Data Commons). That's huge reach. But note: the $3.6 billion is an estimate, and it includes gifts of goods and volunteer time, not just cash. Still, it's a massive awareness day.

GivingTuesday also spurs volunteering: 9.2 million people volunteered on that day (GivingTuesday Data Commons). That's a great way to engage people who might not be ready to give money. And it's a gateway for younger donors: globally, 25- to 44-year-olds give twice as much of their income as those over 55 (CAF World Giving Report). Millennials and Gen Z are more likely to give through DAFs, too—42% of giving Millennials used a DAF in the past year (Financial Planning). So it's not either/or.

Comparing the Two: A Head-to-Head

As the table shows, DAFs are about depth, while GivingTuesday is about breadth. But which one should you invest in?

Our Verdict: It Depends—But Here's the Smart Move

If you're a small or mid-sized charity without a major donor program, start with GivingTuesday. It's a low-barrier way to attract new donors and volunteers, and it can build momentum. Plus, the data shows that empathy and perceived effectiveness drive giving (Nature Communications). GivingTuesday is a perfect opportunity to tell stories that evoke empathy and show impact.

If you have a base of affluent donors, don't ignore DAFs. They're a growing source of funding, and many donors prefer them for tax reasons. But don't expect DAFs to solve your fundraising problems overnight. The share of households that donate has fallen from 65% in 2008 to about 49.6% by 2018 (NPTrust), so you need to broaden your donor base.

Our recommendation: do both, but sequence them. Use GivingTuesday to attract new donors and collect emails. Then, in the following months, cultivate those donors—especially the younger ones—and consider offering a DAF option for those who are interested. Remember, 60% of Millennial and Gen Z donors plan to give more in the next 12 months (Vanguard Charitable). That's your future.

Bottom Line

The single best move is to launch a GivingTuesday campaign this year, and use it as a springboard to build relationships with new donors. For your major donors, set up a simple DAF acceptance process—it's a low-cost way to capture six-figure gifts. But don't rely on DAFs alone; they're a tool for the wealthy, not the masses. GivingTuesday is your gateway to the next generation of givers.
