Question 1

What is a AI API Cost Calculator?

Accepted Answer

An AI API cost calculator estimates the cost of using large language model APIs based on token usage. AI APIs charge separately for input (prompt) and output (completion) tokens.

Question 2

How does the AI API Cost Calculator work?

Accepted Answer

Cost = (input tokens ÷ 1000) × input rate + (output tokens ÷ 1000) × output rate Then: Rates are per 1,000 tokens (or per million tokens on newer models) Then: Monthly cost = cost per request × monthly request volume Then: Input tokens are typically cheaper than output tokens.

Question 3

Can you give an example of how to use the AI API Cost Calculator?

Accepted Answer

Example: Input GPT-4o: 500 input + 200 output tokens, 1000 req/month gives a result of ~$3.25/month.
