How many tokens are in a page of text?
A standard A4 page (about 500 words in English, single-spaced) consumes roughly 650 to 750 input tokens for most generative AIs (Claude, GPT, Gemini, Mistral). The common rule of thumb is 1 token ≈ 0.75 word in English. Quick cost estimate: multiply page count by 700 tokens, then apply the model rate.
A standard A4 page (about 500 words in English, single-spaced) consumes roughly 650 to 750 input tokens for most generative AIs (Claude, GPT, Gemini, Mistral). The common rule of thumb is 1 token ≈ 0.75 word in English. Quick cost estimate: multiply page count by 700 tokens, then apply the model rate. Example: analyzing a 10-page document with Claude Sonnet costs ~7,000 tokens × $3/million = $0.021 input. If the AI replies with 500 words (~700 output tokens), add 700 × $15/million = $0.0105. Total: ~$0.03 to analyze 10 pages with a mid-length reply. On Ask Aurel, this cost is shown at the end of each response for full transparency.
