The verdict in three sentences
WordPress remains unbeatable upfront but its total cost over 3 years climbs with plugins, maintenance and breaches. A headless stack (Next.js + Sanity) costs 2 to 3 times more to build but delivers +30% performance and a lower TCO by month 30. The right call depends on your horizon: under 24 months, WordPress; beyond, custom.
Initial build: WordPress wins
| Item | WordPress | Headless (Next.js + Sanity) |
|---|---|---|
| Initial build (USD) | 9,000 - 16,000 | 20,000 - 34,000 |
| Delivery time | 4-6 weeks | 8-12 weeks |
| Theme / components | Purchase $80-260 | Custom included |
| Editor training | Half a day | One day |
| Typical Lighthouse perf | 45-70 | 90-99 |
| Security posture | Medium | High |
On the entry quote alone, WordPress wins by 40-55%. But a B2B site lives 5 to 7 years: the real metric is total cost of ownership.
3-year TCO: the reversal
| Annual item | WordPress | Headless |
|---|---|---|
| Premium plugin licenses | 800 - 1,600 USD | 0 - 400 USD |
| Hosting | 400 - 1,200 USD | 260 - 800 USD |
| Maintenance / updates | 3,200 - 6,400 USD | 1,600 - 3,200 USD |
| Security patching | 1,000 - 2,600 USD | 260 - 800 USD |
| Estimated annual total | 5,400 - 11,800 USD | 2,100 - 5,200 USD |
2026 order of magnitude. Custom saves $3,300 to $6,600/year in operations, which repays the build gap in 24 to 36 months.

Wei, CIO of a B2B software vendor in Singapore, compares two quotes for the corporate site: WordPress at $13,000, headless at $30,000. Build gap: $17,000.
In operations, WordPress costs $9,000/year (plugins, agency, security), headless $4,000/year. Annual saving: $5,000. The upfront gap is repaid in about 3.4 years ($17,000 / $5,000). Over 5 years: WordPress = 13,000 + 45,000 = $58,000; headless = 30,000 + 20,000 = $50,000. Wei saves $8,000 over 5 years and gains +32% performance, a decisive argument for a vendor whose site is the product showcase. She picks headless.
FAQ
Is WordPress less secure? It powers 43% of the web, so it draws most attacks. In 2026, 90% of WordPress hacks come through an unpatched plugin. Headless shrinks the attack surface by decoupling front from back.
Can headless have a simple back office? Yes: Sanity or Strapi offer an editing interface as accessible as WordPress, with real-time preview. Editor training fits in one day.
At what horizon does custom pay off? 2026 order of magnitude: 24 to 36 months. Below 2 years of planned operation, WordPress remains the best cost/value ratio.
Is SEO better with headless? SEO depends on performance and structure, not the CMS. A Next.js site loading in under 1.5s scores Core Web Vitals points that a heavy WordPress build struggles to reach.
Can I migrate from WordPress to headless later? Yes, but migration costs $8,000 to $16,000. If you know your site will live past 4 years, going headless directly avoids the double spend.
