What is the ChatGPT API Usage Calculator?

The ChatGPT API Usage Calculator helps developers estimate the cost of using different ChatGPT models based on input and output token usage. By entering the number of tokens and selecting the model, the tool calculates the cost for both input and output tokens and provides the total API expense. This allows developers to plan their usage, manage budgets, and better understand the pricing differences between ChatGPT models before making API calls.

How to Use:

1. Enter Input Tokens: Add the number of input tokens your request will send to the API.
2. Enter Output Tokens: Input the number of tokens you expect the model to generate in response.
3. Select ChatGPT Model: Choose the model you want to calculate pricing for, each with its own token cost rates.
4. Click “Calculate”: The tool computes the input cost, output cost, and total API cost instantly.
5. Review Result: The calculator displays individual token costs and the final total so you can estimate your API usage expense accurately.
