LLM API cost calculator

Client

Multiply token counts by your own per-million rates to plan spend. Use with token estimate when you need rough counts from pasted text first.

Common use cases

  • Compare input vs output pricing when drafting a feature that streams long answers.
  • Project monthly spend from average tokens per request and daily volume.
  • Pair with token estimate or messages JSON tools to fill in token counts first.

Common mistakes to avoid

  • Using list prices without your actual contract tier

    Enter the rates you pay—or conservative placeholders—not headline marketing numbers alone.

  • Forgetting cached-input or batch discounts

    This page does not model provider-specific discounts; adjust rates manually.

FAQ

Does this call a pricing API?

No. You type token counts and rates; all math runs locally.

Which currency is shown?

Whatever unit you use for the price fields—the tool does not convert currencies.
