The verdict in three sentences
A slow WordPress site loaded with vulnerable plugins costs more in maintenance and SEO losses than a well-run migration. Moving to headless Next.js in 2026 runs between USD 6,000 and 16,000 depending on scope, for a site that is three times faster and 40% cheaper to maintain. If your mobile PageSpeed score is under 50 and you patch vulnerabilities every month, the migration already pays off.
Why migrate: the real cost of standing still
WordPress is great for publishing fast, but a brochure site carrying 25 plugins becomes slow, fragile and hard to evolve. Next.js generates static or server-rendered pages served via CDN, with a headless CMS (Sanity, Strapi or Contentful) for editing. The result: speed, security and a codebase you own.
| Criterion | Optimized WordPress | Headless Next.js |
|---|---|---|
| Mobile load time | 3.8 s | 1.2 s |
| Mobile PageSpeed score | 45-60 | 90-99 |
| Attack surface | High (plugins/PHP) | Reduced (static/CDN) |
| Annual maintenance | USD 1,000 - 2,000 | USD 550 - 1,100 |
| Hosting cost/month | USD 40 - 100 | USD 0 - 50 |
| Security updates | Monthly, mandatory | Rare, non-blocking |
How much it costs and how long it takes
Budget depends on page count, editorial richness and integrations (forms, booking, payment). Expect a 6 to 10 week timeline for a 10 to 30 page brochure site.
| Item | Scope | 2026 estimate (USD) |
|---|---|---|
| Audit + migration plan | Content, SEO, redirects | 700 - 1,500 |
| Headless CMS integration | Sanity/Strapi + models | 1,400 - 3,400 |
| Next.js development | Design system + pages | 2,800 - 6,500 |
| Content reuse + 301s | 10-30 pages | 550 - 1,700 |
| QA + go-live | Testing, DNS, monitoring | 700 - 1,900 |
| Total | Brochure site | 6,000 - 16,000 |

Maria runs an HR consulting firm in Toronto. Her WordPress site (18 plugins) loads in 4.1 s, faces 2 intrusion attempts a month and costs her USD 1,900/year in maintenance and fixes. She migrates to Next.js for USD 9,000. After migration: maintenance drops to USD 1,050/year (USD 850 saved), PageSpeed goes from 48 to 96, and a three-times faster load lifts contact-form conversion from 1.9% to 2.8%. On 3,000 visits/month, that means 27 extra leads per month. The migration pays for itself within the year from the first conversion uplift.
FAQ
Will I lose my search rankings by migrating? No, if the 301 redirect plan is complete and URLs are preserved. A serious audit maps every page; temporary losses are limited to 2-4 weeks before recovery, often with a net gain thanks to speed.
Can I still edit my content easily? Yes. A headless CMS like Sanity offers an editing interface as simple as WordPress, with live preview. Your marketing team publishes without touching code.
How much does hosting a Next.js site cost? Often cheaper: USD 0 to 50/month on Vercel or a CDN, versus USD 40 to 100 for high-performance managed WordPress hosting. Static output also cuts bandwidth costs.
What if I'd rather optimize my current WordPress? Valid if traffic is low and the site is simple: plugin cleanup and caching may suffice. Beyond 5,000 visits/month or strong security needs, Next.js remains more durable.
What is a realistic go-live timeline? 6 to 10 weeks for 10 to 30 pages, including audit, development, content reuse and QA. Specific integrations (payment, booking) can add 1 to 2 weeks.
