Giving Tops $617 Billion While the Donor Base Keeps Shrinking

On paper, 2025 was a record year for American generosity. Total giving crossed $600 billion for the first time, and the sector posted its strongest revenue growth in five years. Look one layer down, though, and the picture is a sector raising more money from fewer people, with the growth concentrated among the largest givers and the smallest donors quietly leaving the base.

For the marketers who run nonprofit acquisition and appeals, that combination changes the job. GivingTuesday falls on December 1 this year, nine weeks from today, and the numbers suggest the campaign that matters most is not the one that wins a first gift on the day, but the one that earns a second gift afterwards.

A Record Total on a Narrower Base

The headline comes from Giving USA 2026, published in June by the Giving USA Foundation and researched by the Lilly Family School of Philanthropy. It puts 2025 giving at $617.20 billion, up 5.7% in current dollars and 3.0% adjusted for inflation. Individuals gave an estimated $394.2 billion, roughly 64% of the total, but their giving rose just 1.4% after inflation. Bequests, at $62.19 billion, grew 19.7%, the fastest of any source.

“U.S. charitable giving exceeded $600 billion in 2025, a milestone that reflects the resilience of American generosity,” said Wendy McGrady, chair of the Giving USA Foundation. The resilience is real. The question for marketers is whose generosity is carrying it.

The Fundraising Effectiveness Project's Q4 2025 report, released in April by the AFP Foundation for Philanthropy and GivingTuesday, answers that directly. Dollars raised grew an estimated 5.0% in 2025, but donor counts fell 3.6%, continuing a downward trend that began in 2021. Most of the growth came from Major and Supersize gifts, where both the number of gifts and total dollars rose, and an exceptionally strong fourth quarter did much of the work: giving was up only 3.7% through the third quarter.

The Second Gift Is the Unsolved Problem

Retention is where the strain shows. The FEP found overall donor retention edged up from 43.1% to 43.3%, helped by repeat donors, while new donor retention stayed flat. The report is blunt about what that means, calling the conversion of a first gift into a second the most consequential unsolved problem in the donor pipeline, and noting the pattern has held across multiple reporting periods.

In commercial terms, this is a customer lifetime value problem. Acquisition keeps working well enough to replace some of the donors who leave, but most first-time supporters never become second-time supporters, so each campaign has to refill a bucket that drains at roughly the same rate. When the donors who stay are disproportionately large givers, the organisation becomes more exposed to a handful of relationships each year.

Fresh transaction data points to where the fix might come from. Fundraise Up's Pulse of the Donor 2026, built on anonymised 2025 transactions from more than 1,000 nonprofits across the US, Canada, the UK and Australia, found average one-time gift sizes fell 1% and US average monthly gifts fell 5.3%. Conversion rates rose anyway, mobile accounted for more than half of donations in three of four markets, and 9% of US donors chose a recurring gift.

The most striking finding concerns channel. Donors who arrived through social converted to recurring giving at twice the rate of email donors within 60 days, despite smaller first gifts, and 12% of social donors enrolled in recurring giving immediately. “Are you built to convert a $25 mobile donor into a $300 annual relationship, or are you still optimizing to maximize that first transaction?” asked Paul Kramer, who leads Stripe for Nonprofits.

Why GivingTuesday Raises the Stakes

GivingTuesday concentrates all of this into a single day. GivingTuesday's 2025 results show Americans gave $4.0 billion on December 2, 2025, up 13% on the prior year, with 38.1 million participants and 19.1 million financial donors, a 3% increase. It is the one moment in the calendar when donor counts reliably rise.

It also sits inside the most concentrated month of the fundraising year. Benchmarks compiled by Nonprofit Tech for Good show that 37% of annual online revenue is raised in December, that 59% of nonprofits now run a monthly giving programme, and that 36% use pop-ups to prompt one-time donors to become monthly donors. The same compilation, citing M+R, puts the average mobile gift at $88 against $168 on desktop, and a Meta fundraising ad return of $0.76 for every dollar spent.

Read together, the data explains the trap. A December surge of small mobile and social gifts looks weak by first-transaction value and weaker still by paid social return, so it is easy to underinvest in exactly the donors most likely to become recurring supporters. Judged on the first gift, the donors most worth keeping look like the least worth acquiring.

A Retention Playbook for the Next Nine Weeks

• Plan the second ask before the first. Map the 60 days after GivingTuesday as a sequence, since that is the window in which social donors in the Fundraise Up data made their recurring commitment.
• Measure channels on 60-day value. Report social and email donors on recurring conversion and second-gift rate, not only on first-gift size or immediate return on ad spend.
• Make recurring the easy default on mobile. With mobile past half of donations in most markets, test a monthly option on the first screen of the mobile form rather than a later upsell.
• Treat first-year donors as a segment. New donor retention has barely moved for several periods. Give first-time givers their own welcome, impact reporting and cadence instead of the general file.
• Show evidence, not just need. Nonprofit Tech for Good cites research finding 75% of donors look for concrete information about a nonprofit's achievements before giving, so build the appeal around outcomes.
• Watch concentration risk. If growth is coming mostly from Major and Supersize donors, track what share of revenue the top tier represents and set a floor for broad-based acquisition.

None of this suggests the sector is in decline. Americans gave more than ever in 2025, and GivingTuesday keeps growing. What the data does show is a funnel that wins first gifts and loses most of those donors a year later, and the organisations that change how they measure the December surge are the ones most likely to still have those donors in 2027.
