The verdict in three sentences
In 2026, managed WordPress remains the cheaper option to buy (8,000-20,000 EUR) but accumulates technical debt and attack surface. A headless Next.js stack costs more upfront (18,000-45,000 EUR) but wins on performance, security and scalability. Over a 3-year TCO, the gap narrows sharply as soon as performance and editorial autonomy matter.
Acquisition cost and monthly cost
A CIO arbitrating must separate build cost from recurring cost. WordPress is cheaper to build; headless needs more engineering but less corrective maintenance.
| Line item | Managed WordPress | Headless Next.js |
|---|---|---|
| Design & build | 8,000 - 20,000 EUR | 18,000 - 45,000 EUR |
| Monthly hosting | 100 - 300 EUR/month | 200 - 600 EUR/month |
| Delivery timeline | 4 - 8 weeks | 8 - 14 weeks |
| Editorial autonomy | High (Gutenberg) | High (headless CMS) |
| Security patches | Frequent (plugins) | Rare (reduced surface) |
| Performance (LCP) | 2.5 - 4 s depending on plugins | 0.8 - 1.8 s |
WordPress excels when content is simple and editors numerous; headless takes the lead once performance, security and multichannel become critical for a group.
3-year TCO and decision factors
Total cost of ownership over 3 years reconciles both approaches. You add build, hosting, maintenance and patches.
| Element (3 years) | Managed WordPress | Headless Next.js |
|---|---|---|
| Build | 14,000 EUR | 30,000 EUR |
| Hosting (36 months) | 7,200 EUR | 14,400 EUR |
| Maintenance & security | 10,000 EUR | 6,000 EUR |
| Incidents & patches | 4,000 EUR | 1,500 EUR |
| 3-year TCO | 35,200 EUR | 51,900 EUR |
The TCO gap (about 17,000 EUR) is justified if performance drives SEO and conversion, if security is a regulatory concern, or if content must feed several channels (site, app, screens). Otherwise, managed WordPress stays rational.
Mini case study
Thomas, CIO of a mid-market services firm, hesitates over redesigning his high-traffic corporate site. His current WordPress site suffers 2 security incidents/year and a 3.4 s LCP. He compares: managed WordPress at 35,200 EUR over 3 years, headless at 51,900 EUR.
By moving to headless, he targets an LCP under 1.5 s and zero vulnerable plugins. With 60,000 visits/month and a 2% form conversion rate, a 0.3-point conversion gain means roughly 180 extra leads/year, offsetting the TCO gap within the first year in his B2B sector.

FAQ
Is WordPress less secure than headless?
WordPress has a wider attack surface due to plugins and a public back office. Headless exposes fewer components, hence fewer urgent patches, but no system is invulnerable.
Is headless always faster?
Generally yes: Next.js static or hybrid rendering delivers sub-2 s LCP where WordPress depends on plugins and caching. The difference shows most on mobile and in SEO.
Can editors stay autonomous with headless?
Yes: headless CMS (Sanity, Contentful) offer rich editing with preview. Editorial autonomy is no longer a WordPress-only advantage.
Which to choose on a tight budget?
Managed WordPress stays rational for a simple corporate site with heavy editorial volume. Headless is justified once performance, security or multichannel become strategic.
What does annual maintenance cost?
Plan roughly 3,000-4,000 EUR/year for WordPress (plugins, patches) and 1,500-2,500 EUR/year for a well-built headless site, excluding hosting.
