Your Donor-Advised Fund Can't Replace Showing Up

The Case for Volunteering Over Writing Checks

You might think: with donor-advised funds (DAFs) holding a record $327.87 billion (DAF Research Collaborative) and the average DAF account at $91,300, why spend a Saturday sorting cans when you could just write a check? But here's the thing—volunteering isn't a relic. It's the most underused lever we have to actually boost generosity. And I'm not talking about warm fuzzies. The science backs this up, and it's something most philanthropy won't tell you.

We've been sold a story that smart giving is about tax efficiency and scale. DAFs, with their 25.2% payout rate (DAF Research Collaborative), seem to suggest the future of charity is financialized. But a major meta-analysis in Nature Communications (2026) found that empathy—the kind you get from direct contact with a cause—is a strong predictor of giving, while perceived effectiveness, the kind you get from a slick grant proposal, predicts giving only weakly under experiment. And here's the kicker: showing donors the consequences of their previous donations increased subsequent giving by 14% (Nature Communications). You can't get that from a tax receipt. You get that from seeing a kid's face light up when you hand them a backpack.

So, should you ditch your DAF and volunteer instead? After looking at the evidence, my answer is a resounding “no, but.” You don't have to abandon your DAF, but if you're not also volunteering, you're missing out on what makes giving stick.

Empathy Is the Engine, and Volunteering Is the Fuel

Let's be honest: most of us give because it feels good, not because we've run a cost-benefit analysis on impact per dollar. The Nature Communications meta-analysis confirms that empathy is a strong correlate of giving—it reliably increases generosity when evoked. And what evokes empathy better than meeting the people you're helping? The report also found that showing donors the consequences of their previous donations increased subsequent giving by 14% and modestly increased satisfaction. That's the mechanism: you give, you see what happened, you give more. It's a virtuous cycle that's hard to replicate with a quarterly statement from your DAF sponsor, no matter how slick their impact report is.

Now, I'm not saying DAFs are evil. They've democratized giving and made it easier to be generous. But they've also made giving easy in a way that can feel abstract. You click a button, you get a tax deduction, and you move on. The IRS allows you to deduct up to 60% of your adjusted gross income for cash contributions (IRS), which is great, but it doesn't build the neural pathways of generosity. Volunteering does. When you show up at a food bank and see the families you're serving, you're not just giving money—you're giving attention, and that attention creates a feedback loop that makes you a better donor.

And before you say you're too busy, consider this: over 75.7 million Americans, or 28.3% of those 16 and older, formally volunteered in 2023 (AmeriCorps & U.S. Census Bureau). That's nearly a third of the country making time. You can, too.

The Numbers Don't Lie: Volunteering Is a Massive Force

Let's put some numbers on this. In 2023, U.S. volunteers gave an estimated 4.99 billion hours of service, with an economic value of roughly $167.2 billion (AmeriCorps & U.S. Census Bureau). That's not pocket change. That's more than the total giving of foundations ($109.81 billion) and bequests ($45.84 billion) combined (Giving USA 2025). And here's a twist: for the first time, virtual volunteering was tracked—over 13.4 million Americans volunteered online or partly online, contributing 1.2 billion hours worth about $41.5 billion (AmeriCorps & U.S. Census Bureau). So even if you can't make it to a physical site, you can still volunteer from your couch.

But the real power of volunteering isn't just the hours; it's the effect it has on your giving behavior. The Nature Communications study showed that feedback increases giving by 14%. When you volunteer, you're essentially providing yourself with feedback in real time. You see the impact with your own eyes, and that makes you more likely to give again, and maybe even increase your donation. Contrast that with the average DAF, where the grantmaking process can feel like a black box. Even with grantmaking up 17.9% to $64.60 billion (DAF Research Collaborative), that money goes out, but the donor doesn't always see the direct result.

And let's talk about who's actually volunteering. It's not just retirees with time on their hands. GivingTuesday 2024 drew 9.2 million volunteers, and 12.9 million gave goods (GivingTuesday Data Commons). That's a lot of people who could be writing checks but are choosing to get their hands dirty. Why? Because it's more satisfying.

My Recommendation: Use Your DAF, But Volunteer Too

Here's my specific, opinionated recommendation: if you have a DAF, don't close it. But you should commit to volunteering at least one hour for every $10,000 you have in that account. That's a ratio that will force you to stay connected. If you have $50,000 in a DAF, that's five hours of volunteering a year. That's nothing. But it will keep you grounded.

Why this ratio? Because the data shows that giving is increasingly concentrated among affluent donors—the top 50 donors gave $16.2 billion in 2024 (Giving USA 2025). And while that's great, it also means that many of these donors are one step removed from the causes they fund. They're writing checks, but they're not seeing the need. And the share of households that donate has fallen from 65% in 2008 to about 49.6% by 2018 (NPTrust). We're becoming a country of big donors and fewer donors. That's not sustainable.

Volunteering is the cure. It builds empathy, and empathy is what drives giving. So, if you're a DAF holder, my advice is to get out of your comfort zone. Go to a local charity, spend an hour, and see what your money is doing. You'll be a better donor for it. And if you're not a DAF holder, don't feel left out. You can still volunteer. The 75.7 million volunteers out there are proof that you don't need a DAF to make a difference.

And remember, the most important thing is to show up. Not just with your checkbook, but with your presence. Because in the end, charity is not just about money—it's about connection.
