Total cost of ownership of a website over 3 years (2026)

The verdict in three sentences

In 2026, the initial quote is only 40 to 55 % of a website's real 3-year cost; the rest goes to hosting, maintenance, SEO and updates. For an EUR 8,000 brochure site (excl. tax), the 3-year TCO reaches EUR 15,000 to 22,000. Planning these items from the start avoids the trap of a site abandoned at 18 months, the fate of 40 % of SME websites.

The real cost structure over 3 years

A website is not a purchase, it is an asset to maintain. The true budget reads over 3 years, not on the launch quote. Here is the typical TCO breakdown of a professional brochure site.

Depending on the options chosen, the 3-year TCO of an EUR 8,000 site sits between EUR 15,000 and 22,000. The initial quote is real, but it is only the starting point.

Comparing ownership scenarios

The cost depends mostly on your choices after go-live: site left as is, maintained, or actively developed. Here are three scenarios with their TCO and return.

The cheapest scenario upfront (abandoned site) is the most expensive in the end: it usually needs a full rebuild at 24 months, i.e. a second complete quote. The active scenario costs more but turns the site into a profitable acquisition channel.

Mini case study

Claire, CFO of an industrial SME in Lyon, receives a site quote of EUR 8,000 excl. tax and wants the true 3-year cost before deciding. She models: hosting EUR 500/year, maintenance EUR 1,400/year, SEO EUR 2,000/year, plus an updates budget of EUR 3,000 over the period. 3-year TCO: 8,000 + 1,500 + 4,200 + 6,000 + 3,000 = EUR 22,700, about EUR 630/month.

She compares it to the no-maintenance alternative: site rebuilt at 24 months, a second EUR 8,000 quote, and 24 months with no organic acquisition. By building the TCO into the budget from the start, Claire secures a site that generates leads for 3 years instead of a dead asset at 18 months. The extra maintenance cost pays off as soon as SEO brings 3 to 4 qualified leads per month.

FAQ

Why is the initial quote so misleading?

Because it only covers design, i.e. 40 to 55 % of the real 3-year cost. Hosting, maintenance, security, SEO and updates make up the rest, and they are what keep the site alive or let it die.

How much is annual maintenance for a brochure site?

Budget EUR 1,200 to 2,200/year for updates, security, backups and small fixes. Below that, the site falls behind technically and becomes vulnerable or slow.

Can I skip SEO to reduce the TCO?

Yes, but the site becomes a static brochure with no acquisition. Without an SEO/content budget of EUR 2,000 to 5,500 over 3 years, it generates almost no inbound traffic and its ROI stays low.

Why are 40 % of SME sites abandoned at 18 months?

Because the maintenance budget was not planned at launch. Without maintenance or content, the site ages, loses rankings and ends up fully rebuilt, doubling the real cost.

How do I budget a realistic TCO?

Start from the quote, add 5 to 10 % hosting, 20 to 30 % maintenance and 15 to 25 % SEO/updates per year. You get a reliable 3-year range to present to the board.
