A free and fast OpenAI Cost Calculator that estimates how much it would cost to use ChatGPT through the OpenAI API based on your usage habits.
It asks you questions about your ChatGPT usage frequency and habits, like how many chats you have per day/week/month, the average length of your conversations, and how often you use advanced features like image uploads.
Based on your inputs, it runs calculations to estimate your monthly API costs if you were using ChatGPT programmatically. This allows you to compare the potential API costs to the cost of a ChatGPT Plus subscription.
Knowing these estimates can help you decide if it makes more financial sense to pay monthly for unlimited ChatGPT access through the Plus subscription or if your usage would be light enough that basic API access is cheaper.
How to use it:
1. Navigate to the OpenAI Cost Calculator.
2. Answer Key Questions:
- ChatGPT Usage: Indicate how often you interact with ChatGPT (Daily/Weekly/Monthly).
