In early 2026 a team led by the Institute of Collective Health at the Federal University of Bahia, Brazil, published a model in The Lancet Global Health of what the 2025 wave of aid cuts will cost in lives. It is the second major estimate; a June 2025 Lancet paper had looked at the dismantling of USAID alone.
The numbers
The cuts the model assumes, comparing projected 2026 aid with 2023:
| Donor | Cut |
|---|---|
| United States | -56.1% |
| United Kingdom | -38.9% |
| Germany | -36.0% |
| France | -18.5% |
The deaths come mostly from HIV/AIDS, malaria, tuberculosis, neglected tropical diseases, diarrheal disease, pneumonia in children, and complications of pregnancy and birth. These are the areas where aid paid for commodities and staff, and where stopping payment stops the service within months.
Why these are models, not counts
Nobody can count deaths that have not happened. The studies take the historical relationship between aid spending and mortality across countries, then project forward under assumed funding paths. The 9.4 million and 22.6 million figures are two branches of the same model; the truth depends on what donors actually do between now and 2030, and on how much recipient governments and other funders backfill. Treat the range as “millions, not thousands,” which is the point that matters.
Private giving cannot fill it
US government foreign assistance ran around $60 billion a year before the cuts. All US private giving to international affairs runs in the low-to-mid $30 billions a year, by Giving USA’s count, and has grown only slowly after inflation. Even if every private international donor doubled their gift, the arithmetic would not close.
That is not a reason to shrug. It is the reason to give carefully. When a field loses half its funding, the cost of the next dollar changes: programs that were fully funded now have gaps, and the cheapest life-saving work is suddenly unfunded alongside the merely good.
Where the evidence points
The programs with the best public evidence of cost per life saved sit squarely in the cut areas:
- Malaria: seasonal preventive medicine for children (Malaria Consortium, about $4,000 per life saved by GiveWell’s 2022 to 2024 estimate) and insecticide-treated nets (Against Malaria Foundation, about $5,500).
- Child nutrition: vitamin A supplementation (Helen Keller Intl, about $3,500).
- Vaccination: cash incentives that raise routine immunization rates in northern Nigeria (New Incentives, about $4,500).
These are GiveWell’s four top charities, and each has a stated funding gap. The estimates predate the aid cuts, and if anything the cuts push the marginal cost down: a nets campaign that lost its government co-funding is cheaper for a private donor to complete than to start from nothing.
What one donor can do
- Send the international share of your giving to programs with a measured cost per outcome, not to general emergency appeals. The appeals are not wrong, but the measured programs are where a small gift is a countable number of lives.
- Give now rather than at year end. Programs cut in 2025 are running down stocks in 2026; the timing matters more than usual.
- Do not wait for governments to reverse course. Some cuts may be partly restored; the model’s baseline already assumes current policy holds through 2030. Aid budgets are set by the people you elect, so the other lever is the ballot: see who is running for Congress in your district and what they have voted for.
Method notes
Death projections are from the Lancet Global Health paper as reported by CIDRAP and the Washington Post, and from the June 2025 Lancet paper as summarized by UCLA. The “$60 billion” figure for pre-cut US foreign assistance is our round number for total foreign aid obligations in recent years (ForeignAssistance.gov reports roughly $60 to $70 billion for fiscal 2023); USAID’s own share was smaller. Private giving is from Giving USA’s annual reports.
