About the AI Token Cost Calculator

What this calculator helps you estimate

Large language models bill by tokens—roughly pieces of text processed in and out of the model. Small changes in prompts, completion length, or traffic multiply into real dollars. This utility helps you:

• Token costs — translate prompt and completion token counts into per-request and batch totals using configurable per-model rates.
• AI usage and monthly burn — simulate average daily requests and working days to project monthly and yearly LLM API cost.
• Model comparison — line up OpenAI, Anthropic Claude, DeepSeek, and other configured providers on the same workload to see relative pricing.
• Budgeting and planning — use budgets, per-feature estimates, and heuristics so you can align engineering choices with spend guardrails.

Whether you are sizing a chatbot, a RAG pipeline, or batch content generation, the goal is the same: transparent, reproducible cost math you can sanity-check before you commit to architecture or contracts.

Professional, trustworthy guidance

Rates in the tool come from your deployment’s configuration and should always be verified against each vendor’s official pricing page before you make billing or procurement decisions. The interface is designed to be readable in both light and dark theme, lightweight, and focused on clarity—not noise.
