When to use it

Use the calculator before launching a feature, comparing provider defaults, or deciding whether a smaller routing model can handle routine requests.

Common cost drivers

Long prompts, long responses, retries, agent loops, hidden background jobs, and sending the same context repeatedly can dominate monthly cost.

Source notes

Pricing data lives in JSON so it can be updated as provider rates change. Verify model rates against official provider pages before making buying decisions.

FAQ

Questions teams ask before choosing

How accurate is this LLM API cost calculator?

It is a planning estimate using editable pricing data. Verify official provider pricing before making a purchase decision.

What usually drives monthly LLM API cost?

Request volume, output length, retries, long system prompts, context stuffing, and using premium models for routine tasks usually drive spend.

How should teams reduce LLM API costs?

Route simple requests to cheaper models, cache repeated context, cap output tokens, and measure cost by feature instead of only by provider.
