The verdict in three sentences
A trilingual EN/AR/FR website with RTL support for Arabic costs 30 to 50 % more than an equivalent monolingual site. The 2026 budget in Dubai sits between 24,000 and 48,000 AED (roughly 6,500 to 13,000 USD), over a timeline of 8 to 14 weeks. The real premiums come not from design but from professional translation, RTL work and hreflang management.
The specific premiums of multilingual builds
Each extra language multiplies content, translation and maintenance. Arabic adds the technical complexity of RTL (right to left).
| Line item | Premium vs monolingual | 2026 estimate |
|---|---|---|
| Pro translation FR | 0.11 - 0.15 USD/word | 500 - 1,000 USD/lang |
| Pro translation AR | 0.13 - 0.20 USD/word | 700 - 1,400 USD |
| RTL adaptation | +8 to 15 % of dev | 2,000 - 4,000 USD |
| Multilingual CMS | Config & workflow | 1,700 - 3,400 USD |
| Hreflang & intl SEO | Tags & sitemaps | 1,000 - 2,000 USD |
| Maintenance x langs | +40 % recurring | variable |
RTL is not a simple mirror: it requires reworking alignments, directional icons, forms and sometimes Arabic typography to stay legible and professional.
Overall budget and timeline in AED/USD
A trilingual B2B export site is priced by page volume and word count to translate.
| Tier | Budget AED | Budget USD | Timeline |
|---|---|---|---|
| Site 8-12 pages | 24,000 - 33,000 | 6,500 - 9,000 | 8 - 10 wks |
| Site 15-20 pages | 33,000 - 42,000 | 9,000 - 11,400 | 10 - 12 wks |
| Site + blog & SEO | 42,000 - 48,000 | 11,400 - 13,000 | 12 - 14 wks |
The most common international SEO trap: misconfigured hreflang tags or missing reciprocal declarations, so Google fails to serve the right language version. An end-of-project hreflang audit avoids this.
Mini case study
Karim, export director of a food-industry SME in Dubai, orders a trilingual EN/AR/FR site of 16 pages to prospect across the Gulf, Europe and North Africa. Budget chosen: 38,000 AED (about 10,400 USD), including 7,500 AED of pro translation (FR + AR) and 3,200 AED of RTL adaptation. Timeline: 11 weeks. From the second month live, the Arabic version generates 40 % of Gulf contact requests, validating the RTL investment. Estimated ROI within 6 months on a single export contract.

FAQ
Why does a multilingual site cost more?
Each language adds translation, integration, testing and maintenance. The overall premium is 30 to 50 %; Arabic in RTL adds 8 to 15 % of extra development.
Should I use a professional translator or AI?
For a premium B2B site, professional translation (0.11-0.20 USD/word) remains recommended, optionally AI-assisted then reviewed by a native translator, especially for Arabic.
Is RTL really necessary for Arabic?
Yes: without RTL support, Arabic reading is degraded and lacks credibility with Gulf or North African audiences. It signals seriousness for export.
How do I avoid hreflang SEO problems?
By declaring complete, reciprocal hreflang tags, with a sitemap per language and a control audit before go-live. A bad config can sink international rankings.
Can I add a language later?
Yes, if the site is built on a multilingual CMS from the start. Adding a 4th language then costs mainly translation and integration, not a rebuild.
