You pay per page for structure, not text
Document parsing costs more than OCR because it hands back clean fields instead of raw text. That saves engineering time at scale. Compare the raw-text route on the OCR cost calculator.
Per-page parsing math
Document AI pricing splits by extraction depth: plain OCR runs $1โ$1.50 per 1,000 pages, structured form extraction $10โ$50, and specialized parsers (invoices, W-2s) $10โ$30 per 1,000. Vision-capable LLMs undercut the middle tier โ a page image through a cheap multimodal model costs $0.002โ$0.01 with comparable field accuracy on clean documents. Where dedicated parsers still win: handwriting, skewed scans, and tables spanning pages. The volume threshold to test the LLM route: above ~10k pages monthly the savings clear the engineering time within a quarter.
