Total Cost of Ownership: What a Business Website Actually Costs to Run

The license fee is the smallest number in the budget

Three of the four platforms YCTheme builds on — WordPress, Joomla and TYPO3 — are open source and cost nothing to download. Shopify is the exception: it is a subscription service, and the monthly plan is the first thing everyone sees. This visibility creates a persistent illusion: that open-source websites are “free” and Shopify is “expensive”.

In practice, the license is close to irrelevant to what a business spends over the life of a website. The real money goes into hosting, implementation, upgrades, security work, extensions, integrations and the hours an internal team spends operating the system. A website’s total cost of ownership is dominated by labor and by how the platform’s release cycle forces that labor to be scheduled.

Comparing platforms honestly means comparing those structural costs, not the price tag on the download button.

Six cost layers every platform carries

Whatever the platform, a business website accrues costs in roughly the same six layers. The difference between WordPress, Joomla, TYPO3 and Shopify is not whether these layers exist, but where the cost lands and who is forced to pay attention to it.

Implementation. The initial build: design, templating, content modeling, data migration, integrations. This is the one layer every budget includes, which is why it is also the one layer teams over-optimize while ignoring the other five.

Hosting and infrastructure. Open-source platforms need a server, a TLS certificate, a database, backups and someone to keep them patched. Shopify folds hosting into the subscription, which is precisely why the subscription costs what it costs.

Upgrades. Every platform has a release cycle with a support end date. Staying inside the supported window is not optional hygiene; it is the difference between applying routine updates and performing an emergency modernization project. Our TYPO3 v12 to v13 upgrade guide shows what that work actually involves when it is planned, and the Joomla upgrade planning guide does the same for another stack — the point both make is that upgrades are a recurring project cost, not a one-off.

Security and incident response. Core updates are free, but the work of testing them against a live site, cleaning up after a compromised plugin and recovering from an outage is labor. Open-source platforms shift this cost to the site owner; Shopify absorbs the platform side and leaves the store owner responsible only for apps and content.

Extensions and apps. Licenses for plugins, Joomla extensions, TYPO3 extensions or Shopify apps. These look small individually and become a meaningful annual line item collectively, because each one also adds compatibility surface for every future upgrade.

Operating labor. Editor training, content publishing workflows, troubleshooting, small feature requests. This is the largest and least visible layer. A platform that saves twenty minutes per publishing task pays for a surprising amount of license fees over three years.

WordPress: cheap core, expensive periphery

WordPress itself is free, and quality hosting for a typical business site is inexpensive. The cost structure shifts to the periphery: the theme, the plugin stack and the security exposure that comes from running the most targeted CMS in the world.

The honest WordPress budget therefore allocates generously to maintenance. Plugins need updates, and updates occasionally break things; a professional update workflow — inventory, staging, verification, as we describe in our WordPress maintenance practice on the WordPress development page — is a recurring cost that “free” hides. Sites that skip it tend to pay the same money later, concentrated into a crisis.

Where WordPress wins on cost: editorial labor. For a team publishing regularly without deep technical skills, the publishing workflow is the cheapest of the four platforms to operate. When the site grows into many plugins, custom post types and overlapping page builders, per-plugin licenses and compatibility testing start to add up, and the platform’s cost advantage narrows.

Joomla: license-free, integrator-shaped

Joomla’s cost profile resembles WordPress with less plugin-marketplace overhead and more dependence on a competent integrator. The core handles a substantial amount — multilingual structure, template overrides, custom fields — without commercial extensions, which keeps the extension layer lean for mid-sized organization sites.

The trade-off is that the ecosystem is smaller. When a requirement does fall outside core, the answer is more often custom development or a commercial extension from a specialist vendor, not a $15-per-year plugin. Joomla also runs on the same kind of self-managed hosting as WordPress, so the hosting and security layers behave identically: real servers, real patch cycles, real operator attention.

Joomla’s release policy gives each major series roughly four years of support — Joomla 5, for example, is supported into late 2027 — which makes the upgrade rhythm predictable and lets teams plan version moves as scheduled projects rather than surprises.

TYPO3: pay for governance, get lifecycle discipline

TYPO3 is the most expensive of the three open-source platforms to implement. Setup is done by integrators in configuration files rather than admin toggles, and an enterprise-grade site assumes professional involvement from day one. Nothing about that is accidental: the platform is designed for organizations where the website is governed infrastructure, not a side project.

What the higher implementation cost buys is the most disciplined lifecycle of the four. Each TYPO3 LTS release receives around three years of free security support, after which extended long-term support is available as a paid option. That means the upgrade cost is known, schedulable years in advance, and driven by a published calendar rather than by accumulating pressure. For organizations with compliance requirements, that predictability is itself worth money.

Where the costs concentrate: integrator hours for configuration and upgrades, and version migrations that periodically require reworking site configuration. Where they do not: license fees, commercial plugin renewal stacks, and the operational fragility of a large plugin periphery. Our TYPO3 development service exists almost entirely around that lifecycle — which is itself a statement about where TYPO3’s costs live.

Shopify: the subscription is a bundle, not a markup

Shopify’s monthly fee looks like pure cost until you itemize what it replaces: hosting, server patching, database administration, TLS, CDN, platform security and the entire “is the site up” layer of operational worry. The subscription is a bundle of the layers that open-source platforms charge à la carte in labor.

The costs that do land on a Shopify merchant are apps and theme customization. A store’s app stack — reviews, subscriptions, upsells, shipping — can quietly exceed the plan fee, and each app adds both a monthly bill and a degree of theme and checkout coupling that affects future theme work. Leftover app code in themes is a well-known source of maintenance cost, one we deal with regularly through our Shopify development service.

Shopify’s other structural cost is the transaction fee, which scales with revenue in a way fixed hosting costs do not. For high-volume stores, that scaling matters more than any plan comparison; for stores below that threshold, the flat predictability of the subscription is usually a net win.

Comparing on a three-year horizon

A single-year comparison flatters cheap-to-launch options. Over three years, the patterns stabilize:

• WordPress — low launch cost, moderate recurring maintenance, cost risk concentrated in plugin sprawl and security incidents.
• Joomla — moderate launch cost, lean extension overhead, cost risk concentrated in integrator availability.
• TYPO3 — high launch cost, predictable scheduled upgrades, cost risk concentrated in integrator hours; the most stable cost curve of the three.
• Shopify — predictable platform cost that scales with sales, near-zero infrastructure labor, cost risk concentrated in app licensing and transaction fees.

Notice that none of these is “cheapest” in the abstract. Each is cheapest for a specific operating pattern: WordPress for editorial-heavy sites with modest technical ambition, Joomla for mid-sized structured sites, TYPO3 for governed organizational sites, Shopify for product-led stores. That is the same conclusion our CMS selection framework reaches from the requirements side — cost is a function of fit, not of platform.

Using TCO correctly in the decision

The practical use of a cost model is not to pick the cheapest platform. It is to force three conversations that launch-focused budgets skip.

First, what does year two look like? Every platform above carries an upgrade or support-cycle obligation inside any three-year window. Budgeting for the build while ignoring the scheduled version move — a Joomla 5-to-6 transition, a TYPO3 LTS rotation, a WordPress major-version cleanup, a Shopify theme refresh after an Online Store 2.0-style change — is the most common way website budgets fail.

Second, whose hours does this consume? A platform that requires an integrator for every content-model change is expensive for a team that publishes weekly. A platform an intern can extend with plugins is expensive for an organization that must control what goes live. Cost follows operating model.

Third, when does the cost curve say stop? There is a point on every platform where accumulated upgrade debt, plugin overhead and workaround maintenance exceed the cost of a clean rebuild. Recognizing that point is the substance of the platform migration decision, and it is a cost judgment, not a feature comparison: migration is justified when the expected cost of staying exceeds the expected cost of moving, and not before.

Total cost of ownership does not replace the platform selection framework; it prices it. The teams that get websites right treat the launch invoice as the first line of a three-year budget, and pick the platform whose cost curve matches the way they actually work.
