Mathematical Formula & Step-by-Step Guide
Primary mathematical equation used by this model:
Cost per Call = (InTokens × InPrice + OutTokens × OutPrice) / 1,000,000
- Enter your Daily AI API Requests and Avg Input Prompt Tokens per Call (or load GPT-4o ($2.50 / $10.00), Claude 3.7 Sonnet ($3 / $15), Gemini 2.5 Flash ($0.10 / $0.40) with one click) to establish your baseline scenario.
- Adjust Avg Output Completion Tokens per Call and Input Price ($ per 1M Tokens) to see how the primary result and visual breakdown bar respond in real time.
