Cloud Translation is priced monthly based on usage. This page states usage fees and notes price differences between v2 and v3. Translation usage is calculated in millions of characters, where 1 million = 106 characters.

If you pay in a currency other than USD, the prices listed in your currency on Cloud Platform SKUs apply.
* Price is per character sent to the API for processing, including whitespace characters. Empty queries are charged for one character. Google charges on per character basis, even if the character is multiple bytes, where a character corresponds to a (code-point). For example, translating "こんにちは" to English counts as 5 characters for the purposes of billing. The free tier is only available for Translation API v3.
Google does not charge extra for language detection when you do not specify the
source language for the translate method;
the Language Detection price applies to detect method calls.
Prices are 'pro rata' (proportional and incremental). Charges are scaled to the number of characters actually provided to the service. For example, if you send 75,000 characters for processing within a month, you are charged $1.50.
This pricing is for applications on personal systems (for example, phones, tablets, laptops, or desktops). Please contact us for approval and pricing to use the Translation API on embedded devices (for example, cars TVs, appliances, or speakers).
If you are requesting translation or language detection for over a billion characters per month, then contact a sales representative to discuss discount pricing.
