Understanding the OpenAI API Cost Calculator for ChatGPT

The OpenAI API Cost Calculator for ChatGPT is a tool designed to estimate the expenses involved in utilizing OpenAI models within applications or systems. This tool aids in estimating the costs associated with using language models like GPT-3.5 and GPT-4 for text generation and completion.

How Does It Work?

The calculator offers a user-friendly interface where users can select between two primary models: GPT 3.5 and GPT 4. The user inputs the number of tokens in their prompt and the number of tokens they expect in the model’s response. Tokens, in this context, represent units of text that the model processes or generates.

Cost Estimation

Upon selecting a model and entering the token counts, the tool calculates an estimated price based on the pricing structure provided by OpenAI for these models. Each model has its unique pricing for input and output tokens per 1,000 units.

For instance, GPT 3.5 incurs a cost of $0.0010 for input tokens and $0.0020 for output tokens per 1,000 tokens used. On the other hand, GPT 4 costs $0.03 for input tokens and $0.06 for output tokens per 1,000 tokens.

Visual Representation

The tool has a simple yet intuitive layout. Users can select their desired model via radio buttons and input the token counts for prompt and response. Upon clicking the “Calculate Price” button, the tool performs the necessary calculations and displays the estimated price for the provided input.

Customizable Implementation

This tool is presented as an HTML file, which can be embedded within websites easily. The provided JavaScript function performs the calculations based on user inputs and updates the displayed estimated price accordingly. Inline styles are used to enhance the visual presentation of the form elements, creating a clean and modern interface.

Integration Possibilities

This tool can be utilized within websites or applications that leverage OpenAI’s models for text generation or completion tasks. Integrating it into your platform can help users estimate costs before executing tasks with the OpenAI API, aiding in budget planning and decision-making.


The OpenAI API Cost Calculator for ChatGPT serves as a valuable resource for estimating expenses associated with utilizing OpenAI’s language models. Its user-friendly interface, accurate estimations, and ease of integration make it a practical tool for businesses and developers leveraging AI-powered text generation.
