About LLM Pricing

LLM Pricing is a web-based calculator for estimating the cost of language model API usage. You enter the number of input (prompt) tokens, cached input tokens, and output (completion) tokens, together with the cost per million tokens for each of those categories, and the tool returns a total cost. The page also lists model prices per million tokens, with options to show only selected models, clear a selection, sort by input or output cost, and compare models.

Key features

  • Calculates total API cost from input, cached input, and output token counts
  • Separate rate fields per million input, cached input, and output tokens
  • Browse model prices listed per million tokens
  • Show only selected models or clear the selection
  • Compare models by input and output cost
  • Displays a last-updated date for the price data
Best for: Developers and teams who want a quick estimate of LLM API costs from token volumes and per-million-token rates.
Good for
  • Handles cached input tokens as a separate cost line rather than folding them into input cost
  • Lists model prices in one place with selection and comparison controls
  • States the tokenizer caveat that direct token-based price comparisons may not be entirely accurate
Watch out for
  • Results depend on the token counts and per-million-token rates entered or selected
  • Cross-model price comparisons based on tokens may not be entirely accurate because models use different tokenizers
  • Price data carries a last-updated date, so figures may not reflect current provider pricing

LLM Pricing FAQ

What token types does the calculator use?
It takes the number of input tokens (prompt tokens), cached input tokens, and output tokens (completion tokens), along with the corresponding cost per million tokens for each.
Can token-based prices be compared directly between models?
Not reliably. The page notes that different models use different tokenizers, so direct token-based price comparisons may not be entirely accurate.
Is the model price list kept current?
The page displays a "prices last updated" date, which indicates when the listed figures were last refreshed.
Is something wrong or out of date?
