AI Token Cost Calculator

Enter your expected token usage and instantly see costs across all major AI providers. Last updated: . Provider prices can change without notice, so verify directly before committing spend.

How do I calculate AI API costs? Multiply your input tokens by the provider's input rate and your output tokens by the output rate, then divide by 1 million. For example, 500,000 input + 100,000 output on GPT-5.4 ($2.50/$15.00 per 1M) = $1.25 + $1.50 = $2.75 per request cycle. This calculator runs that math across all 126 tracked models so you can spot the cheapest option in one glance.

How do I use the AI token cost calculator?

  1. Enter expected input tokens — roughly 0.75 words or 4 characters per token. A 2,000-word prompt is ~2,700 tokens.
  2. Enter expected output tokens — model responses are usually 200–2,000 tokens unless you explicitly set max_tokens.
  3. Set monthly request volume — multiplies the single-request cost to estimate monthly spend.
  4. Compare rows — the table sorts cheapest-first. Cached-input rates drop many providers by 75–90%.
  5. Click a model to jump to its provider page for context, FAQ, and rate-limit details.
