# Pay per usage

## What is pay per usage?

For our [**PRO**](https://gpt.space/pricing) **and** [**STANDARD**](https://gpt.space/pricing) plans users only, once you cross the threshold of 10M monthly [credits](https://support.gpt.space/pricing-and-models/what-is-a-credit) in Google Sheets [GPT formulas](https://support.gpt.space/products/gpt-for-google-sheets), we will block the requests and ask you to activate pay per usage. 

Once activated this will let you continue use **unlimited** **credits** at the cost of $0.006 USD (or subscription currency equivalent) per 1000 [credits](https://support.gpt.space/pricing-and-models/what-is-a-credit).

Once activated, pay per usage will only charge for credits used after your included monthly quota of 10M monthly credits
