AI cost tools

Start with tokens, then narrow by provider.

Use the general LLM token calculator as the wide entry point, then move into provider-specific tools, embedding cost, the RAG calculator, or the AI agent calculator for task-level workflow cost.

I only have prompt text Start with the LLM Token Calculator. I have OpenAI usage logs Use direct token counts, cached input, and Batch API options. I use prompt caching Start with Claude cache writes, or use DeepSeek for cache-hit and cache-miss fields. I use multimodal or grounding Open Gemini options for audio, cache, and grounding. I am building RAG Estimate indexing, embedding, retrieval context, and query generation cost. I only need embeddings Estimate indexing tokens, embedding runs, and refresh-frequency cost. I am building an agent Estimate model calls, tool overhead, retries, and cost per completed task.

FAQ

Choose the right AI cost calculator

What can I calculate with these AI cost tools?

These tools estimate token usage, per-request cost, daily cost, monthly cost, and annual API spend across major LLM providers.

Should I start with the LLM token calculator or a provider calculator?

Start with the LLM token calculator for a broad estimate, then use provider-specific calculators when you need cached input, batch pricing, grounding, or cache-hit details.

Are the estimates exact billing numbers?

No. The tools are planning calculators. Production billing should be verified against provider usage dashboards and official token-counting APIs.
