LLM Translation Cost Simulator

Build your language programme pair by pair, set word volumes, and compare monthly API costs across all major models.

Note: Prices are fetched weekly from the OpenRouter public API and reflect standard API list prices as of the date shown per model. This tool estimates API token costs only — it excludes infrastructure, human post-editing (MTPE), TMS integration, or volume discount pricing. Always verify rates directly with providers before budgeting.
