Cloud Translation pricing

You are charged for Cloud Translation based on monthly usage. This page states usage fees for Cloud Translation - Basic and Cloud Translation - Advanced. Text translation usage is calculated in millions of characters, where 1 million = 10⁶ characters. Formatted document usage is calculated in document pages.

Prices per month

You are charged for the amount of text that Cloud Translation processes, such as the text that you include in a detect language or translate text request. Note that if you don't specify a source language for the translate method, Cloud Translation detects the source language for you. You are only charged for the text that you provided; there's no additional charge for the detection in addition to the translation. For example, if you submit 1,000 characters for translation without specifying the source language, you are only charged for the 1,000 characters.

Prices are pro rata (proportional and incremental). Charges are scaled to the number of characters actually provided to Cloud Translation. For example, if you send 575,000 characters for processing within a month, you are charged $1.50. The first 500,000 characters are free, and then you are charged for the additional 75,000 characters sent for detection, translation, or both.

	500,000 to 1 billion characters^* per month	$20^# per million characters

† Credit usage applies collectively to both Cloud Translation - Basic and Cloud Translation - Advanced. The credit is up to $10, based on your usage and does not roll over. This credit does not apply to formatted document translations.

# If you pay in a currency other than USD, the prices listed in your currency on Cloud Platform SKUs apply.

Cloud Translation - Advanced

The following pricing information applies to the detectLanguage, translateText, batchTranslateText, translateDocument, and batchTranslateDocument method calls. Cloud Translation does not charge for other requests such as glossary creation.

For batch translations, the number of characters processed equals the number of characters in the source language multiplied by the number of target languages. For example, if you submit 5,000 characters and include 2 target languages for a batch translation request, the total number of characters to process is 10,000. If the operation fails, Cloud Translation only charges for the successful translations that were returned.

Feature	Metered usage	Price
TranslateDocument with NMT models (DOCX, PPT, and PDF formats only) for online and batch calls	Per page^‡ sent to the API per month	$0.08
Total usage for language detection, text translation, batch text translation, and XLSX document translation by using the NMT model	First 500,000 characters^* per month	Free (applied as $10 credit every month)†
	500,000 characters^* and above per month	$20^# per million characters
	Over 1 billion characters^* per month	We recommend that you contact a sales representative to discuss discount pricing.
TranslateDocument by using AutoML Translation custom models (DOCX, PPT, and PDF formats only)	Per page^‡ sent to the API per month	See AutoML Translation pricing

‡ Pages are counted by page breaks or slides. Documents cannot average more than 4000 characters or 500 words per page.

* Price is per character sent to the API for processing. For details about counted characters, see Charged characters

# If you pay in a currency other than USD, the prices listed in your currency on Cloud Platform SKUs apply.

Charged characters

To calculate usage, Google counts usage on a per character basis, even if a character is multiple bytes. Each character corresponds to a code point.

You are charged for all characters that you include in a Cloud Translation request, even untranslated characters. This includes, for example, whitespace characters. If you translate <p>こんにちは</p> to English, it counts as 12 characters for the purposes of billing.

Google also charges for empty queries. If you make a request without any content, Google charges one character for the request.

Charged projects

For Cloud Translation - Basic, Google charges the project that is associated with the private key that you used to make authenticated requests.

For Cloud Translation - Advanced, Google bills against the project that contains the translation model that you use, not against the project that you used to make the request. For example, the following request was made in project-number-1. However, the caller has access to and used a model (custom or NMT model) that is located in project-number-2. In this case, Google charges project-number-2.

POST https://translation.googleapis.com/v3/projects/project-number-1/locations/us-central1:translateText
{
  "model":"projects/project-number-2/locations/us-central1/models/model",
  "sourceLanguageCode": "en",
  "targetLanguageCode": "ru",
  "contents": ["Dr. Watson, please discard your trash."]
}

Similarly, for a batch request that uses multiple models from multiple projects, the projects that contain the models are charged and not the project that makes the request.

Other Google Cloud costs

If you store documents to be translated in Cloud Storage, or use other Google Cloud resources in tandem with Cloud Translation, such as App Engine instances, then you are also billed for the use of those services. See the Google Cloud Pricing Calculator to determine other costs based on current rates.
