A foundation does not have a net worth in the way a person does, but it does have an endowment, and that is the number people usually mean. For the bill and melinda gates foundation networth, the endowment was reported at roughly $70 billion in recent years, according to the foundation’s own financial reporting, which makes it one of the largest private charitable foundations in the world. The organization is now officially called the Gates Foundation, after Melinda French Gates stepped down as co-chair in 2024, so you will see both names online.
Endowment versus net worth
An endowment is the pool of assets, such as stocks and bonds, that a foundation invests so it can pay for grants. Think of it as the principal. A U.S. private foundation is generally required to pay out at least about five percent of its assets each year for charitable purposes, and the Gates Foundation has typically given more than that. So the endowment is both a measure of size and a limit on how much can be given over time.
The number changes with markets. When stocks rise, the endowment grows, and when they fall, it shrinks, even before any grants are paid.
Where the money came from
The foundation was started by Bill and Melinda Gates in 2000 by merging earlier family giving vehicles. Most of its assets came from Bill Gates, who has directed large amounts of his Microsoft wealth into it over the years. Warren Buffett also gave enormous sums, beginning with a 2006 pledge to donate the majority of his Berkshire Hathaway shares, with a large portion going to the Gates Foundation. Buffett later stated he would shift his giving after his death to other family trusts and no longer continue contributing to the Gates Foundation after his passing. That detail matters for how large the endowment might be in the future.
How much it gives away
Annual grant spending has run into the billions of dollars. In recent years, the foundation reported budgets of roughly $7 billion to $9 billion. In 2025 it announced a plan to spend about $200 billion over the next two decades and then close in 2045, a plan that was widely reported. That commits it to a higher pace of giving than before, and it means the endowment is intended to be spent down rather than preserved indefinitely.
Where the grants go
- Global health. Vaccines, malaria, polio eradication and maternal and child health, often through partnerships with groups such as Gavi and the World Health Organization.
- Poverty and development. Agriculture support for smallholder farmers, and financial services for the poor.
- Education in the United States. Grants for schools and postsecondary pathways.
- Gender equality and other programs. Initiatives aimed at women’s health and economic opportunities.
Reading the bill and melinda gates foundation networth figure
Where do the numbers come from? The foundation publishes annual financial statements and the endowment size is stated there. Independent sources such as Forbes and the Chronicle of Philanthropy repeat the figures. Because it is a charity and not a company, there is no valuation exercise like there is for a startup. The uncertainty comes only from market movement and from the date of the report.
When you see differing numbers, check the year. A figure from 2018 will not match one from 2023, and a figure that includes pledged but undelivered gifts will differ from one counting only assets on hand.
How it compares with other foundations
Few charitable foundations come close in size. Large ones include the Wellcome Trust in the United Kingdom, the Novo Nordisk Foundation in Denmark, and the Mastercard Foundation, and in some years the Novo Nordisk Foundation has been reported to hold assets on a similar scale because of its holding in the pharmaceutical company. Rankings change with stock prices, so I would not state a firm order.
Criticism and debate
As with any large philanthropy, it draws both praise and questions. Supporters point to vaccine and disease progress. Critics ask how much influence a single private foundation should have over global health priorities, and whether donor-directed giving is accountable to the people it serves. Those debates are healthy and are well documented if you want to read more.
Bottom line
The bill and melinda gates foundation networth is best understood as an endowment of about $70 billion in recent reporting, funded mainly by Bill Gates and Warren Buffett, with a plan to spend it down by 2045. The exact figure moves with markets, and estimates change over time, so check the foundation’s latest financial report for a current number.
