The verdict in three sentences
For a corporate website, WordPress stays cheaper to buy (build 22 000-38 000 CAD) but exposes you to plugin debt and security maintenance. Headless costs more to build (32 000-55 000 CAD) but offers LCP < 2s performance, a reduced attack surface and content reuse across surfaces. On a 3-year TCO, the gap narrows sharply: headless is justified as soon as brand image, performance and security take priority.
Build, licensing and maintenance
Purchase cost tells only part of the story. Here is the comparison of structuring line items for a corporate site in 2026.
| Item | WordPress | Headless CMS |
|---|---|---|
| Initial build | 22 000 - 38 000 CAD | 32 000 - 55 000 CAD |
| CMS licence | 0 CAD | 0 - 1 300 CAD/mo (volume) |
| Security maintenance | 550 - 1 200 CAD/mo | 800 - 1 600 CAD/mo |
| LCP performance | 2 - 4s (plugin-dependent) | < 2s |
| Attack surface | High (plugins) | Reduced (API) |
| Updates | Frequent, risky | Decoupled, controlled |
WordPress wins on entry cost and plugin ecosystem; headless wins on performance, security and content reuse across multiple surfaces (site, app, subsidiaries).
3-year TCO and migration cost
The real trade-off is on total cost of ownership. Here is a 2026 order-of-magnitude calculation over 36 months, maintenance included.
| Scenario | Build | 3-year maintenance | 3-year TCO |
|---|---|---|---|
| WordPress | 32 000 CAD | ~32 400 CAD (900 CAD/mo) | ~64 400 CAD |
| Headless CMS | 44 000 CAD | ~43 200 CAD (1 200 CAD/mo) | ~87 200 CAD |
| Migration WP -> headless | - | one-off cost | 16 000 - 29 000 CAD |
The TCO gap (~23 000 CAD over 3 years) must be weighed against risk: a WordPress plugin breach or an SEO underperformance can cost more in reputation and lost traffic for a corporate brand.
Mini case study
David, digital lead at a 90-person Toronto firm, must choose the foundation for the corporate site. Scope 24 pages, bilingual EN/FR. WordPress quote 34 000 CAD (maintenance 900 CAD/month) vs headless 46 000 CAD (maintenance 1 200 CAD/month). Over 3 years: WordPress 66 400 CAD, headless 89 200 CAD. The 22 800 CAD gap is settled in favour of headless: the firm targets LCP < 2s for SEO and plans to reuse content in a future HR app, which amortises the headless premium.

FAQ
WordPress or headless for a corporate site?
WordPress if budget dominates and content stays simple editorial. Headless if performance, security and multi-surface reuse are strategic. For a visible corporate brand, headless is often the durable choice.
Why does WordPress cost more in maintenance?
Plugin debt forces frequent, risky updates plus active security monitoring. Expect 550 to 1 200 CAD/month versus 800 to 1 600 CAD for headless, but with a far larger attack surface on the WordPress side.
Is headless really faster?
Yes: by serving static or pre-rendered pages via API, a headless site regularly hits LCP < 2s, versus 2 to 4s for a plugin-heavy WordPress. It is a direct SEO factor.
How much does a WordPress-to-headless migration cost?
Between 16 000 and 29 000 CAD depending on content volume and integrations. You migrate content, rebuild the front end and redirect SEO. Plan it when WordPress debt becomes unmanageable.
What is the 3-year TCO?
Order of magnitude: WordPress ~64 000 CAD, headless ~87 000 CAD. The ~23 000 CAD gap is justified by performance, security and content reuse for a corporate brand.
