WordPress vs Custom Website: 3-Year Cost, Security, Maintenance

Short answer

For a brochure site or blog your team will update itself, WordPress usually costs less over three years than a custom website: by our calculations, about US$900 if you build it yourself on managed WordPress hosting, and roughly US$2,950 to US$4,770 with a freelancer, managed hosting and monthly updates. A custom site starts at about US$6,250 (C$8,900) over three years at ZeniTech, hosting and maintenance included. WordPress loses its edge when the site must integrate with your software, run logic specific to your business or pile up plugins: every plugin adds updates to track and attack surface, and Patchstack counted 11,334 new vulnerabilities in the WordPress ecosystem in 2025, 91% of them in plugins.

The short answer

Pick WordPress if your site is mainly about publishing: service pages, a blog, news, and someone on the team wants to edit content without a developer. The software is free and open source (GPLv2 or later), the official directory lists more than 74,000 free plugins, and finding someone to maintain it is easy. According to W3Techs, WordPress runs 40.2% of all websites, or 58.7% of sites whose content management system is known (data as of October 2, 2026).

Go custom when the site becomes a business tool: it calculates quotes using your rules, syncs with your CRM or ERP, opens a customer portal, or has to meet strict performance and security targets without depending on a dozen third-party plugins.

Unlike Wix, WordPress is not a lock-in: a self-hosted WordPress site can move to another host or provider. The real trade-off is less about ownership and more about maintenance and what you need the site to do.

What each option really costs over three years

The number to compare is the total paid over three years, hosting and maintenance included. The table starts from published prices and ZeniTech’s prices; totals are our calculations. Your own time building and maintaining the site is not counted.

Option	What you pay	3-year total (our calculations)
DIY WordPress on WordPress.com Business	US$25/month billed yearly	US$900 (≈ C$1,282)
WordPress built by a freelancer, Kinsta managed hosting (Single 20GB)	Setup of an assumed 40 hours at US$25–49/hour, hosting US$350/year, 1 hour of upkeep per month at the same rate	≈ US$2,950 to US$4,770
Same, bilingual with Polylang Pro	Add €99 the first year, then €49.50 per year on renewal (50% discount)	≈ US$3,170 to US$5,000
ZeniTech custom brochure site	From C$3,500 (≈ US$2,457), plus C$150/month (≈ US$105) hosting and maintenance	From C$8,900 (≈ US$6,250)
ZeniTech custom professional site	C$7,500 (≈ US$5,266), plus C$150/month hosting and maintenance	C$12,900 (≈ US$9,060)

ZeniTech calculations, not quotes; taxes extra. Prices checked October 2, 2026 on the WordPress.com, Kinsta and Polylang pricing pages. The 40 setup hours and one hour of monthly upkeep are assumptions; the hourly range is Clutch’s average cost for WordPress development companies across all regions (updated September 21, 2026). Local agencies in North America often charge more per hour. Conversions at Bank of Canada rates of October 1, 2026 (US$1 = C$1.4243; €1 = C$1.6030), rounded.

WordPress’s hidden cost: maintenance and security

WordPress core is solid: Patchstack recorded only 6 core vulnerabilities in 2025. The risk comes from what you add. Of the 11,334 new vulnerabilities in the ecosystem in 2025, a 42% increase over 2024, 91% were in plugins and 9% in themes. Worse, 46% were not fixed in time for public disclosure, and for the most heavily exploited flaws, the weighted median time to first exploit was 5 hours.

In practice, a WordPress site without regular updates is not “done”; it ages badly. You also have to track the PHP version on your host. WordPress recommends PHP 8.3 or greater; according to php.net, PHP 8.2 stops receiving security fixes on December 31, 2026, and PHP 8.3 on December 31, 2027.

Keep plugins to a minimum and remove the ones you no longer use.
Choose actively maintained plugins with recent updates.
Set up automatic backups and a staging copy for major updates.
Put in writing who runs updates, how often, and what happens if the site is hacked.

Ownership and portability: WordPress does well

WordPress is licensed under the GPLv2 or later: you can run it, study it, change it and move it. A self-hosted WordPress site migrates from one host to another with its files and database. That is a real difference from a builder like Wix, whose help center says a Wix site has to run on Wix’s servers.

Two caveats. Premium themes and plugins are often tied to a yearly licence. With WPML, for example, the plugin keeps working without renewal but stops receiving updates. And the domain, hosting and admin accounts should be in your name whatever platform you use.

For a custom site, portability depends on the contract: require the code in a repository in your name, hosting in your name and a written assignment of rights.

Bilingual sites, SEO and performance

WordPress is not multilingual out of the box. You add a plugin such as Polylang (free version, or Pro from €99 per year) or WPML (€99 for the first year of Multilingual CMS). Configured properly, they create one URL per language and hreflang annotations. If you sell into Quebec, where a business website must offer a complete French version, make this choice at the start.

For SEO, WordPress gives you good basics with a well-known SEO plugin. Performance depends mostly on the theme, page builders and number of plugins: a lean WordPress site can be very fast, a heavy one very slow. The same is true of custom builds. Either way, write Core Web Vitals targets into the contract.

When WordPress is the right choice

Often, and it is worth saying plainly. If your site is mainly a publishing platform, WordPress gives you an editor many people already know, a huge range of plugins and a large pool of professionals to maintain it.

You publish often: blog, news, case studies, job postings.
Several people will edit content and already know the WordPress editor.
Your needs are covered by common, well-maintained plugins: forms, newsletter, simple booking.
Your first-year budget is a few thousand dollars.
Someone, in-house or on contract, will handle monthly updates.

When custom is worth the price

Custom pays off when the site is a sales or operations tool, and piling up plugins starts to cost you in time, speed or risk.

The site must talk to your CRM, ERP, calendar or industry software, in both directions.
You need logic specific to your business: calculated quotes, booking by your rules, a customer portal, dashboards.
You want a smaller attack surface: no third-party plugins to watch every week.
You are going after searches where strong competitors already hold page one and you need control over every template.
The site is part of a product or platform that will keep evolving for years.

The middle path: headless WordPress

There is an in-between. In a “headless” setup, WordPress is only the back office where content is written, and a custom front end displays it through the WordPress API. Your team keeps the editor it knows, and the public site does not expose plugins.

The trade-off: two systems to host and maintain, and plugins that change what visitors see stop working. It makes most sense when a lot of content already lives in WordPress and the site needs to do more than publish.

The decision table

Use this as a quick test. If most of your answers land on the left, WordPress is probably the better choice; if they land on the right, get quotes for custom work.

Frequently asked questions

Is WordPress cheaper than a custom website?

Over three years, usually yes. By our calculations, DIY WordPress on WordPress.com Business costs about US$900, and WordPress built by a freelancer with managed hosting and monthly upkeep about US$2,950 to US$4,770. A custom brochure site at ZeniTech costs at least C$8,900 (about US$6,250) over three years, hosting and maintenance included.

Is WordPress secure?

The core is: Patchstack recorded only 6 core vulnerabilities in 2025. The risk comes from plugins and themes. Of the 11,334 new vulnerabilities that year, 91% were in plugins and 9% in themes, and 46% were not fixed in time for public disclosure. A WordPress site with few plugins, updated monthly and backed up, is reasonably safe.

How much does WordPress maintenance cost?

Count hosting, for example US$350 per year for Kinsta’s Single 20GB plan, premium plugin licences, and update time. At one hour per month and the US$25 to US$49 average hourly cost Clutch reports for WordPress firms, upkeep alone comes to roughly US$900 to US$1,760 over three years.

Can I edit a custom website myself?

Yes, if the provider builds an admin area. You should be able to change text, images, prices and everyday pages yourself; structural or feature changes go through the developer. Ask to see the editing interface before you sign.

Can I leave WordPress later?

Yes. WordPress is open-source software under the GPL: you can export your content or move the site to another host. Moving from WordPress to a custom site is a redesign, so keep a list of your URLs to set up 301 redirects and protect your Google traffic.

What is headless WordPress?

It means using WordPress only as the writing tool, with a custom front end that displays the content through the WordPress API. Your team keeps the editor it knows and the public site does not expose plugins, but there are two systems to host and maintain.

Is WordPress good for a bilingual English–French site?

Yes, with a multilingual plugin such as Polylang or WPML, which creates one URL per language and hreflang annotations. If you sell into Quebec, the French version must be complete and at least as accessible as the English one, so check that forms, automated emails and checkout follow too.
