Google Translate API pricing is based on usage. Translation usage is calculated in millions of characters (M), where 1 M = 10⁶ characters. For more information, see the Pricing FAQ.

Important: Google Translate API v2 requires billing information for all accounts before you can start using the service. See instructions below on how to enable billing.

• Usage fees:
  • Translation:
    • $20 per 1 M characters of text, where the charges are adjusted in proportion to the number of characters actually provided. For example, if you were to translate 500K characters, you would be billed $10.
  • Language Detection:
    • $20 per 1 M characters of text, where the charges are adjusted in proportion to the number of characters actually provided.
• Usage limits:
  • Google Translate API has a default limit of 2 M chars/day. You can increase this limit up to 50 M chars/day in the Google Developers Console by following the instructions below.
  • If you need to translate more than 50 M chars/day, please contact us
