The verdict in three sentences
Over 5 years, WordPress and a headless CMS cost almost the same for the corporate website of an 800-employee company: about USD 100,000 for WordPress versus USD 100,000 to 120,000 for a headless stack such as Sanity or Strapi with Next.js. WordPress is cheaper upfront (USD 40,000 versus 60,000), but maintenance and plugins cost USD 12,000 per year versus 8,000, and you must handle an average of 3 critical vulnerabilities per year across the plugin ecosystem. The decision therefore rests on security, performance, editorial governance and in-house skills, not on price alone.
The 5-year total cost comparison
A 2026 order of magnitude for a 60 to 120-page bilingual corporate site with newsroom, careers and news, built by a New York agency.
| Item | WordPress | Headless (Sanity or Strapi + Next.js) |
|---|---|---|
| Initial build | USD 40,000 | USD 60,000 |
| Maintenance, updates, plugins | USD 12,000/year | USD 8,000/year |
| CMS licences | Premium plugins included above | USD 0 to 4,000/year (self-hosted Strapi free, Sanity usage-based) |
| Hosting | Included in maintenance | Included (Vercel or similar, plus CMS) |
| 5-year total | USD 100,000 | USD 100,000 to 120,000 |
| Critical vulnerabilities to patch | 3 per year on average | Smaller attack surface, static front end |
| Mobile performance (typical LCP) | 2.5 to 4 s depending on theme | 1 to 2 s |
The maths is simple: WordPress = 40,000 + 5 x 12,000 = USD 100,000. Headless = 60,000 + 5 x 8,000 = USD 100,000, plus USD 0 to 20,000 of licences over 5 years depending on editor seats and API usage at Sanity. A partial rebuild mid-cycle is more common on WordPress, where a theme or page builder becomes obsolete within 3 to 4 years.
Beyond price: the deciding criteria
| Criterion | WordPress | Headless |
|---|---|---|
| Communications team autonomy | Very good, familiar interface | Good, custom-configured interface |
| Multi-level approval workflow | Plugins required | Native in Sanity, configurable in Strapi |
| Security | Plugin-dependent, frequent updates | Back-office separated from public site |
| Multisite and subsidiaries | WordPress Multisite, sometimes heavy | One CMS, several front ends |
| Vendor pool | Very large | Smaller, React skills needed |
| Content reuse (app, intranet, kiosks) | Limited | Content delivered via API |
| Vendor lock-in | Low | Medium, insist on documentation |
For a CIO, the key point is security: every WordPress plugin is a third-party dependency. With 25 to 35 plugins on a typical corporate site, the 3 annual critical vulnerabilities force emergency updates. Headless separates the editing tool from the public site, which sharply reduces the attack surface and simplifies security audits.
How to decide in 30 minutes
Choose WordPress if the site remains an editorial showcase, your team already knows the tool and the upfront budget is capped. Choose headless if you have several subsidiaries or languages, a legal approval chain, content to reuse elsewhere (app, intranet) or strong performance and security requirements. Either way, require ownership of code and content in the contract, plus handover documentation.
Mini case study
Rachel, CIO of an 800-employee New York company in professional services, compares both options. On WordPress, each critical vulnerability takes on average 6 hours of emergency work billed at USD 150 per hour, i.e. 3 x 900 = USD 2,700 per year on top of maintenance, and USD 13,500 over 5 years. Added to USD 100,000, WordPress reaches about USD 113,500. Headless with Sanity at USD 2,000 per year reaches USD 110,000. The gap becomes negligible, and Rachel picks headless for its native approval workflow and a front end deployed outside company servers, two points requested by the security team.

FAQ
Is a headless CMS harder for the communications team?
Not if it is well configured: the agency builds tailored content models and live preview. Plan 1 to 2 days of training, i.e. USD 2,000 to 4,000.
Sanity or Strapi?
Sanity is a hosted service, free up to a usage threshold and then billed by editor seats and API calls. Strapi is open source and self-hosted with no mandatory licence, but needs USD 1,500 to 2,500 per year in hosting and administration.
Can WordPress be properly secured?
Yes, with few plugins, weekly updates, a web application firewall and monitoring. That is what the USD 12,000 per year of maintenance in our comparison covers.
Can WordPress run headless?
Yes, WordPress can serve as the back-office with a Next.js front end. It keeps the familiar interface but also the plugins and their updates, at a cost close to pure headless.
How long does each option take to deliver?
Allow 10 to 12 weeks for WordPress and 12 to 16 weeks for headless on a 60 to 120-page site. The content modelling phase explains the gap.
