The verdict in three sentences
When a WordPress site piles up 18 plugins and 3 breaches in 12 months, the hidden cost of maintenance often exceeds the cost of migrating. In 2026, moving 200 pages to Next.js with a headless CMS costs USD 13,000 to 30,000 (EUR 12,000 to 28,000) over 8 to 12 weeks. The return shows up in security (60% lower maintenance cost), speed (load time cut by 3) and peace of mind for IT.
Why WordPress gets expensive past a certain size
WordPress remains a good tool for a simple site. With 200 pages and 18 plugins (forms, multilingual, SEO, caching, page builder, security), every update can break a template, and every abandoned plugin becomes an entry point. Each of this year's 3 incidents took 2 to 4 days to resolve. Next.js serves static or server-rendered pages with no database exposed to the public, and the headless CMS (Sanity, Strapi, Payload, Directus) is reachable only by editors.
| Annual cost item | Current WordPress | Next.js + headless CMS |
|---|---|---|
| Premium plugin licences | USD 1,000 to 1,600 | USD 0 to 300 |
| Updates and testing | USD 3,200 to 4,900 | USD 900 to 1,600 |
| Security incidents (3 per year) | USD 4,300 to 7,500 | USD 0 to 1,100 |
| Hosting | USD 650 to 1,300 | USD 300 to 1,600 |
| Headless CMS | included | USD 0 to 1,300 |
| Total security maintenance | USD 7,500 to 12,400 | USD 3,000 to 5,000 (-60%) |
The migration budget line by line
The price depends mainly on the number of templates, the quality of existing content and integrations (CRM, ATS, newsletter).
| Work package | Detail | 2026 cost (USD) | Duration |
|---|---|---|---|
| Scoping and audit | Inventory of 200 pages, templates, plugins | 1,600 to 3,200 | 1 week |
| CMS modelling | Content schemas, roles, approval workflow | 2,200 to 4,300 | 1 to 2 weeks |
| Front-end development | 8 to 15 Next.js templates, design system | 5,400 to 13,000 | 3 to 5 weeks |
| Content migration | Import script, clean-up, media | 1,600 to 4,300 | 1 to 2 weeks |
| Redirect plan | 200 301 redirects, Search Console checks | 900 to 2,200 | 3 to 5 days |
| Integrations | CRM, forms, analytics | 1,300 to 3,000 | 1 week |
| Total | 13,000 to 30,000 | 8 to 12 weeks |
The critical point: do not lose your traffic
Most failed migrations fail on redirects. Every indexed URL needs a 301 redirect to its exact equivalent, tested before cut-over. Title tags, structured data and internal linking must also be preserved. With a clean plan, the traffic dip is usually limited to 5 to 10% for 2 to 4 weeks, then the speed gain lifts rankings back up.
Mini case study
Julian, IT director at an 80-employee services firm in New York, spends USD 9,900 a year on WordPress maintenance and security fixes. He approves a USD 21,000 migration over 10 weeks. Maintenance drops to USD 4,000 a year, saving USD 5,900 annually. Load time falls from 3.9 s to 1.3 s and contact requests rise 9%, about 6 extra leads a month. Excluding sales gains, the migration pays back in 3.5 years; with 2 extra contracts a year at USD 8,600 margin, it pays back in under 1 year.
