WordPress or a custom build?
WordPress is cheapest to get started with, while a custom website costs more upfront but gives full control over performance, security, and features. Calculate the total cost over three to five years: plugin licenses, security maintenance, and optimization mean custom development often catches up as requirements grow. Headless WordPress is a middle ground that keeps the editorial environment.
WordPress powers a large share of the web for good reason: it’s fast and cheap to get started with. A custom website costs several times more to build. Yet the choice isn’t obvious – because the build price tag and the total cost over five years are two different things, and they don’t always point the same way.
The price tag and the total cost are different things
A template-based WordPress site often lands at SEK 50,000–150,000, one with a custom design at SEK 150,000–500,000. A custom website starts around SEK 500,000 and can reach SEK 2 million for larger platforms.
Looking only at those numbers, WordPress always wins. But the build is just the first line item. The interesting comparison is what the website costs you per year to own, run, and change – and there the picture looks different depending on how far you deviate from standard needs.
Where the WordPress cost hides
Four line items rarely show up in the first quote but recur every year:
- Plugin licenses. Forms, multilingual, SEO, security, page builders – the licenses are cheap individually but together become an annual pile that renews for as long as the site lives.
- Security maintenance. WordPress is the world’s most attacked CMS, and most breaches happen through outdated plugins. Updates, monitoring, and testing after every update are ongoing work.
- Performance optimization. Themes and plugins load pages with code. Caching solutions, image optimization, and cleanup efforts need to be repeated as the site expands.
- Customizations at the template’s edge. As long as your needs fit within the template, changes are cheap. Outside it, every special need becomes a consulting job that bends the platform – and the next update can bend it back.
None of this makes WordPress the wrong choice. It makes total cost the right number to compare.
The break-even point where custom wins
A rough calculation with round assumptions: a designed WordPress site for SEK 300,000, where the business has many special needs, might run SEK 150,000–250,000 per year in licenses, security work, optimization, and customizations. A custom equivalent for SEK 800,000, built for those exact needs, might land at SEK 40,000–60,000 per year in maintenance.
With those assumptions, the curves meet around year three, and after that the custom solution is cheaper every year – while also performing better. The point isn’t the numbers themselves but the mechanism: the break-even point comes earlier the more special needs, integrations, and performance requirements you have. For a site with standard needs, it might never come, and then WordPress is right even over five years.
The middle ground: headless WordPress
It’s possible to keep the best of WordPress – the editorial environment the content team already knows – and still build the visitor experience custom. In a headless setup, WordPress becomes a pure content hub, while a standalone frontend pulls in the content via API.
You avoid migrating the editorial team to a new tool, while performance, design, and features get built without the limits of the template and plugin layer. The cost lands between the two options, since the frontend is built as in a custom project while the content side already exists.
How to choose
- Standard needs, content-focused, limited budget: WordPress – with few plugins and a maintenance plan.
- Many special needs, integrations, or high performance requirements: custom – calculate the three-year total cost, not the build price.
- A strong editorial team that loves its tool, but the web presence needs a lift: headless WordPress with a custom frontend.

Frequently asked questions
Is WordPress free?
The core is open source and costs nothing, but a business site is rarely free to run. Premium themes, plugin licenses, hosting, security maintenance, and consulting hours for customizations add up to an ongoing cost that often surprises anyone who only budgeted for the build.
How do we know we've outgrown WordPress?
Typical signals: every change requires developer help even though you chose the platform to avoid that, the site gets slower with every plugin, integrations rely on fragile connections, and security updates get postponed out of fear something will break. Two or more of these are good reason to calculate alternatives.
Do we lose SEO if we switch from WordPress to custom?
Not if the move is done right: keep or redirect every URL, preserve content and metadata, and launch with at least the same performance. Many sites improve their Core Web Vitals after the switch, which strengthens rankings rather than weakening them.
Can we keep WordPress for the blog and build the rest custom?
Yes, that's a common setup. WordPress continues as the editorial tool while the rest of the site is built separately – either through a headless setup where content is pulled via API, or as a separate part of the site. That puts the platform to work on what it's best at.
What does a custom website cost compared with a WordPress site?
A WordPress site often lands at SEK 50,000–500,000 depending on whether it's built on a template or a custom design. A custom website typically costs SEK 500,000–2,000,000. Always compare the total cost over a few years, though, including licenses, maintenance, and customizations – that's where the picture can flip.
