The results are displayed in a clear, organized format with visual charts where applicable, making it easy to understand what the numbers mean. The tool handles all the complex math behind the scenes, so you get accurate results with zero effort.

Formula Used

The AI Token Cost Calculator uses the following formula:

Input Cost = (Input Tokens / 1,000,000) × Input Price. Output Cost = (Output Tokens / 1,000,000) × Output Price. Cost Per Request = Input Cost + Output Cost. Daily Cost = Cost Per Request × Requests Per Day. Monthly Cost = Daily Cost × Days Per Month. Annual Cost = Monthly Cost × 12.

The calculation is performed automatically when you click the Calculate button, ensuring error-free results every time. Understanding the formula helps you interpret the results more effectively and see exactly how each input affects the final outcome.

A token is the basic unit of text AI models process. One token ≈ 0.75 words in English. For example, 'Measurely' tokenizes to ['Measure', 'ly'].

How is token cost calculated?

Cost = (input tokens × input price / 1M) + (output tokens × output price / 1M). Cached input tokens use a discounted rate.

Which model is cheapest overall?

Amazon Nova Micro is the cheapest at $0.035/1M input and $0.14/1M output. Other budget options include Gemini 2.5 Flash Lite and Nova Lite.

What is prompt caching?

Prompt caching reuses previously processed input tokens at 50-90% off. Models like GPT-4o, Claude, and Gemini support it.

How many tokens does a typical request use?

Chatbots: 500-1,500 input + 100-500 output tokens. Content generation: 2,000-8,000+ tokens. Code generation: 500-2,000 tokens.
