Formula: billed chars = source chars (incl. spaces) × target languages. NMT text (Basic & Advanced): $20 per 1M after a $10 monthly credit (= first 500k chars, shared Basic + Advanced, not for documents); contact sales above 1B chars on Basic. Flexible Savings Plans ($18 for 1 year / $16 for 3 years per 1M) are not the default. Translation LLM: $10 per 1M input + $10 per 1M output chars. Adaptive translation: $25 + $25 per 1M. Custom (AutoML) text graduated: $80 (0–250M), $60 (250M–2.5B), $40 (2.5B–4B), $30 (4B+) per 1M; training $45/hour, max $300 per job. Documents: NMT $0.08/page, custom $0.25/page (DOCX/PPT/PDF). Official example: 100 emails × 3.1k chars = 310k → NMT $6.20, custom $24.80; 1,000 pages → $80.

How it works
- How is Google Cloud Translation priced?
- Text is billed per character sent, including spaces, multiplied by the number of target languages. NMT (Basic and Advanced) costs $20 per 1M characters after a $10 monthly credit that covers the first 500,000 characters.
- What do Translation LLM and Adaptive translation cost?
- Translation LLM bills $10 per 1M input characters plus $10 per 1M output characters; Adaptive translation bills $25 + $25. Output is usually slightly longer than input — Google's example uses 3.1k in and 3.3k out (ratio ≈ 1.06).
- How much does custom AutoML translation cost?
- Custom text is graduated: $80 per 1M for 0–250M chars, $60 for 250M–2.5B, $40 for 2.5B–4B and $30 above 4B. Training costs $45 per hour, capped at $300 per job.
- How are documents priced?
- Document translation is per page: $0.08 per page with NMT and $0.25 per page with a custom model (DOCX, PPT, PDF). The 500k free characters do not apply to document translation.
- Do the results match Google's examples?
- Yes: 100 emails × 3,100 chars = 310k chars → $6.20 on NMT (no credit) and $24.80 custom; 1,000 document pages → $80. Prices as of 2026-11-02.
