What it Costs to Run Wikipedia: $3m in Hosting; $107m in Salaries

Note: The headline numbers refer to Wikimedia Foundation’s audited FY 2023–2024 figures: about $3.1 million for internet hosting and about $106.8 million for salaries and benefits. Newer FY 2024–2025 figures are included for context where useful.

Wikipedia is one of the strangest miracles on the internet. It is free, mostly written by volunteers, available in hundreds of languages, and somehow still loads when half the planet is trying to look up whether an actor was in that one movie. So when people see the cost breakdownroughly $3 million in hosting but $107 million in salaries and benefitsthe natural reaction is: wait, what?

Shouldn’t the server bill be the monster? Isn’t Wikipedia basically “a website with articles”? And if volunteers write the content, why does the Wikimedia Foundation spend so much on people? The answer is less scandalous and more interesting. Wikipedia is not just a giant online notebook. It is a global public infrastructure project wrapped in software, law, fundraising, security, community support, translation, moderation tools, research, grants, anti-disinformation work, and enough operational complexity to make a normal blog quietly unplug itself.

The famous $3 million versus $107 million contrast is useful because it exposes a modern internet truth: for a mature digital nonprofit, servers are not always the biggest cost. People are.

The Core Numbers Behind the Headline

In FY 2023–2024, the Wikimedia Foundation reported total support and revenue of about $185.4 million and total expenses of about $178.5 million. Within that expense line, salaries and benefits were about $106.8 million, while internet hosting was about $3.1 million. Awards and grants were another major category at about $26.8 million, followed by professional services, donation processing, travel, conferences, depreciation, and other operating expenses.

For FY 2024–2025, the numbers increased: total support and revenue rose to about $208.6 million, total expenses rose to about $190.9 million, salaries and benefits reached about $114 million, and internet hosting rose to about $3.5 million. So the headline remains directionally true even with newer data: the human side of Wikipedia costs far more than the raw hosting line.

Why Hosting Looks So Cheap

The low hosting number surprises people because Wikipedia feels enormous. It supports billions of pageviews, massive archives, media files, search traffic, API access, and a global audience that expects information to appear instantly. But Wikipedia’s infrastructure is not built like a typical ad-tech platform or video streaming service.

Wikipedia is mostly text, and text is delightfully cheap compared with video, short-form clips, infinite-scroll social feeds, or high-resolution gaming assets. Text is the oatmeal of the internet: not glamorous, but efficient, reliable, and somehow still there when everything else is on fire.

Wikimedia also uses a highly optimized infrastructure model. Many pages are served from cached copies, meaning the system does not rebuild every page from scratch every time a reader visits. If ten thousand people look up “solar eclipse” during an eclipse, the platform can often serve a cached version quickly rather than forcing databases to sprint around like caffeinated squirrels.

The Foundation operates a global network of data centers, including locations in the United States, Europe, Asia, and Brazil. The São Paulo data center, opened in 2024, was designed to improve speed and reliability for readers in South America. That matters because even a fraction of a second can affect whether people stick around, especially on mobile connections.

Why Salaries Are the Big Cost

The biggest misunderstanding about Wikipedia is that “volunteer-written” means “free to operate.” Volunteers are the soul of Wikipedia, but they are not a substitute for a technical, legal, security, and operational organization. The Wikimedia Foundation does not pay people to write most encyclopedia articles. It pays people to keep the ecosystem alive.

1. Engineers Keep the Machine Running

Wikipedia runs on MediaWiki, an open-source platform with deep customization. Engineers maintain databases, caching systems, search functions, mobile apps, accessibility features, performance tools, anti-vandalism systems, translation tools, account systems, and APIs used by researchers, developers, search engines, and increasingly AI systems.

When a website at this scale breaks, it does not break politely. It breaks globally. Keeping Wikipedia fast, secure, and available requires site reliability engineers, software developers, data specialists, product managers, designers, and security professionals. Those people do not work for free, nor should they. A global knowledge platform cannot be run on vibes and leftover pizza.

2. Legal and Policy Work Protect the Model

Wikipedia’s open model depends on legal defense, privacy protection, free expression advocacy, copyright expertise, and policy engagement. The Foundation must handle issues involving defamation claims, government pressure, takedown demands, privacy laws, copyright disputes, data regulations, and threats to volunteer editors.

This is not background decoration. If the legal and policy layer fails, the encyclopedia can become less open, less independent, or less safe for contributors. A free knowledge project needs lawyers the way a castle needs walls. Nobody visits for the walls, but they matter when the arrows arrive.

3. Trust, Safety, and Anti-Abuse Work Are Expensive

Wikipedia has to deal with vandalism, spam, harassment, coordinated manipulation, disinformation campaigns, and attempts to influence public knowledge. Volunteer editors handle much of the front-line content work, but the Foundation supports tools, safety programs, policy work, and research that help communities defend the projects.

This is especially important because Wikipedia is no longer just a website people visit. Its content is reused across search results, voice assistants, educational tools, knowledge panels, and AI training pipelines. When Wikipedia is accurate, the wider internet benefits. When it is manipulated, the damage can travel far beyond the original page.

Where Donations Come From

The Wikimedia Foundation is primarily funded by donations. In FY 2023–2024, more than 8 million donors contributed, with an average donation of about $10.58. That is the key to the model: millions of small gifts supporting a resource that remains free for everyone.

Fundraising is not free, though. Donation processing, email campaigns, banner testing, payment systems, donor support, compliance, fraud prevention, and international fundraising all cost money. This is why donation processing appears as a separate expense line. The little banner asking for a few dollars may look simple, but behind it sits a complex fundraising operation that works across countries, languages, currencies, tax rules, and payment networks.

In FY 2024–2025, the Foundation also reported stronger revenue diversification. Wikimedia Enterprise, a paid service for high-volume commercial reusers of Wikimedia content, contributed more meaningfully to revenue. This matters because relying only on donation banners is risky. Reader habits change. Search engines change. AI summaries change. The way people reach information is shifting, and the Foundation is trying to reduce dependence on a single fundraising channel.

Is $107 Million in Salaries Too Much?

The honest answer is: it depends on what you think Wikimedia Foundation should be.

If you think the Foundation’s only job is to keep a text website online, then $107 million in salaries looks huge. If you think its job is to protect, improve, internationalize, legally defend, fund, and future-proof one of the world’s most important public knowledge systems, the number becomes less shocking.

A fair analysis should compare the salaries line not with “hosting,” but with the scope of responsibility. Wikipedia supports hundreds of languages, hundreds of thousands of volunteer editors, more than a dozen free knowledge projects, huge global traffic, and a public-interest mission that operates without advertising. That is not cheap.

Still, skepticism is healthy. Donors should ask whether staffing levels are efficient, whether programs produce measurable value, whether reserves are appropriate, whether executive compensation is reasonable, and whether grantmaking reaches communities effectively. Transparency is not a magic shield against criticism. It is an invitation to examine the numbers like adults, preferably with coffee.

The Real Lesson: Infrastructure Is More Than Servers

The $3 million hosting figure is eye-catching because people associate internet scale with server cost. But Wikipedia’s real infrastructure includes people, governance, trust, security, community systems, legal defense, and long-term sustainability. The servers deliver the pages. The organization protects the conditions that allow those pages to exist.

This is why the salary line dominates the budget. Wikipedia’s value is not simply that it stores articles. Its value is that those articles are created, reviewed, corrected, translated, debated, cited, protected, and delivered under a nonprofit model that resists the advertising incentives shaping much of the web.

In other words, Wikipedia’s biggest cost is not bandwidth. It is stewardship.

What Small Publishers and Startups Can Learn From Wikipedia’s Budget

The Wikipedia cost breakdown offers a useful lesson for anyone building a website, app, nonprofit, media brand, or educational platform: hosting is rarely the whole business. A founder may start with a $20 monthly hosting plan and think the internet is cheap. Then come customer support, compliance, design, security, content moderation, analytics, backups, accessibility, legal templates, payment fees, documentation, and people who know how to fix the thing when it catches fire at 2:13 a.m.

Wikipedia is an extreme case, but the pattern is universal. The more a digital product matters, the more it needs human systems around it. A school website, a medical information portal, a local news archive, or a community forum may not need a $100 million staff, but it still needs responsibility. Somebody has to maintain the software. Somebody has to answer users. Somebody has to update old information. Somebody has to keep bad actors from turning the comment section into a haunted basement.

Experience Section: Practical Reflections on the Cost of Running Wikipedia

Looking at Wikipedia’s budget from a practical, real-world perspective, the most relatable lesson is that public trust is expensive to maintain but easy to underestimate. Many people experience Wikipedia as a simple page that appears after a search. You type a question, click a result, and there it is: clean text, references, dates, names, categories, and maybe a photo of a 19th-century scientist with impressive facial hair. The experience feels effortless, which is exactly why the cost structure can feel confusing.

Anyone who has managed even a small website knows the illusion. At first, the visible cost is hosting. Then the invisible costs arrive. Security updates need attention. Broken links appear. Old pages become inaccurate. Search engines change rules. Users send complaints. A plugin fails. A database backup needs testing. Someone asks for accessibility improvements. Someone else threatens legal action over a sentence they dislike. Suddenly, the “cheap website” is not cheap anymore. It is a living system.

Wikipedia operates this reality at planetary scale. Its volunteers provide extraordinary editorial labor, but volunteers still need tools that work. They need talk pages, watchlists, abuse filters, translation support, reliable login systems, documentation, mobile editing, and protection from harassment. Readers need fast pages, privacy-respecting access, secure connections, and confidence that the site is not quietly turning into an ad farm. Donors need receipts, support, payment security, and proof that their money is handled responsibly.

The most useful way to read the $3 million hosting figure is not “Wikipedia is cheap to run.” It is “Wikipedia has solved many technical delivery problems efficiently.” The most useful way to read the $107 million salary figure is not “people are overpaid.” It is “the hard part of a trusted knowledge system is human work.” Engineers, lawyers, community specialists, product teams, finance staff, fundraisers, researchers, and security professionals are all part of the infrastructure, even if they do not look like servers.

For publishers, educators, nonprofit leaders, and startup teams, the takeaway is clear: budget for the boring work. Budget for maintenance. Budget for trust. Budget for the people who prevent disasters that users never see. The best infrastructure often feels invisible, and that invisibility creates a public relations problem. When everything works, people ask why it costs so much. When it fails, people ask why nobody invested enough.

Wikipedia’s budget is not beyond criticism, but it should be criticized with the right mental model. A free encyclopedia is not free to operate. A volunteer community is not free to support. A global public resource is not free to defend. The miracle is not that Wikipedia spends money. The miracle is that, compared with the commercial internet giants surrounding it, Wikipedia still delivers so much public value without selling attention to advertisers. That is worth understanding before we reduce the conversation to one server bill and one salary line.

Conclusion

The cost to run Wikipedia reveals a surprising but logical truth: the servers are not the expensive part. The expensive part is keeping a global, multilingual, volunteer-powered knowledge system reliable, independent, safe, legally protected, technically modern, and free to readers. The $3 million hosting line shows how efficient text-based, cached infrastructure can be. The $107 million salary and benefits line shows how much human expertise is required to keep the project alive.

Wikipedia is not merely a website. It is an institution of the open web. Its budget should be examined carefully, but not lazily. If we want free knowledge to remain free, somebody has to pay for the boring, essential work that makes it possible. In Wikipedia’s case, that “somebody” is millions of donors giving small amounts so billions of people can keep learning without a paywall, a subscription prompt, or a dancing autoplay ad for miracle socks.
