The AI Translation Cost Calculator estimates the expense of translating text using AI services like DeepL, Google Cloud Translation, AWS Translate, and LLM-based translation (GPT-4, Claude). It compares per-character and per-word pricing across services and language pairs.

공식

Translation Cost = Character Count × Price per Character (or Word Count × Price per Word)

C: Character Count (characters) — Total characters in source text
P: Price per Million Characters ($/1M chars) — Service rate per million characters translated
L_src: Source Language (language code) — Original language of the content
L_tgt: Target Language (language code) — Translation target language

풀어진 예시

입력

100,000 words English to Spanish, DeepL API Pro

결과

Characters: ~500,000. DeepL: $25.00/1M chars = $12.50. Google Cloud: $20/1M chars = $10.00. GPT-4o via API: ~$3.75 (tokens-based). AWS Translate: $15/1M chars = $7.50.

입력

500-page technical manual, English to Japanese

결과

Approximately 2.5M characters. DeepL: $62.50. Google: $50.00. Human translator: $0.12-$0.20/word × 125,000 words = $15,000-$25,000.

피해야 할 일반적인 실수

✕Comparing AI translation cost to human translation without accounting for post-editing (MTPE) time needed for publication quality
✕Using character-based pricing formulas for Chinese/Japanese/Korean where character counts differ significantly from alphabetic languages
✕Not testing translation quality across multiple services for your specific domain — generic cost comparison misses accuracy differences

자주 묻는 질문

Is AI translation good enough to replace human translators?

For internal documents, customer support, and general web content, AI translation (especially DeepL and GPT-4) produces publication-quality results for most European language pairs. For legal, medical, literary, or highly technical content, AI translation should be followed by human post-editing (MTPE). The best workflow is AI draft + human review, which is 3-5x cheaper than fully human translation.

Which AI translation service produces the best quality?

DeepL consistently ranks highest for European languages. GPT-4 and Claude produce excellent results with custom instructions (tone, terminology) and handle context better than traditional NMT. Google Translate is strongest for rare language pairs. For Asian languages, native-trained models often outperform general-purpose services.
