Anthropic Claude API: pricing and cost estimation
A practical guide to estimating Claude API spend, including long-context work and prompt-caching decisions.
Start with a transparent estimate
Estimate input and expected output tokens in the PromptCost calculator. Then confirm the exact model, token direction, cache policy, batch discount and tool charges with the provider.
What to include in the budget
- Input tokens, including system instructions and retrieved context.
- Output tokens, which often dominate generation-heavy workflows.
- Prompt caching, batch processing and long-context terms where available.
- Tool calls, web search, storage or other non-token charges when applicable.
- Retries, evaluation traffic and the buffer needed for production variability.
Best fit
Teams comparing Claude models for agent workflows, document analysis or high-quality generation.
