You are charged for Cloud Translation based on monthly usage. This page states usage fees for Cloud Translation - Basic and Cloud Translation - Advanced. Translation usage is calculated in millions of characters, where 1 million = 106 characters.
Prices per month
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.
Cloud Translation - Basic
Language detection pricing applies to the
detect method call.
Cloud Translation does not charge extra for language detection when you do not
specify the source language for the

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,
PBMT, or NMT
model) that's
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.
