Data extraction cost calculator
Estimate the AI data extraction cost of pulling structured fields — vendor, date, total, line items, and more — out of invoices, receipts, resumes, contracts, forms, and other business documents with a general-purpose model. Enter your document volume, schema, and field count to get a Low / Likely / High monthly cost estimate. Everything runs locally in your browser — no data is sent to any server.

Estimated monthly cost
T9 estimates LLM inference/token cost only. Not included: OCR vendor fees, PDF/image parsing, document-storage fees, vector databases, dedicated parser/extraction-API services, or any other third-party fee — those are billed separately (often per page, not per token) by whatever service converts your source file into processable text.
This is an estimate, not a billing guarantee. Actual costs depend on your provider's exact tokeniser, your real document content and schema, and your billing tier.
How this estimate works
- Extraction instructions / schema
- The document's own text content
Reads the document and returns the requested fields as structured data (JSON).
A small, structured result — the extracted field values, not more prose.
Data extraction is a lopsided workload: the document you send is usually much larger than what comes back. This calculator prices both sides of that call using each model's own input and output rates — which are commonly quite different from each other.
Why document size drives input cost
The full text of the document — every page, every line — is sent as input on every extraction call. A one-page receipt and a forty-page contract cost very differently on the input side, even with an identical extraction schema.
Why schema/instruction size matters
A short list of simple fields ("vendor, date, total") takes far fewer instruction tokens to specify than a large or nested schema with type rules, format examples, and edge-case notes — and that instruction text is resent on every single call, the same as any other system prompt.
Why line items/records affect output tokens
A resume has one record — one set of fields. An invoice usually has several — one set of fields per line item. Output size scales with fields × records, not with document length: a short invoice with 20 line items can produce more output tokens than a long contract with only a handful of top-level fields.
Why model choice changes cost
Extraction is an input-heavy, output-light workload, so a model's input price usually matters more here than its output price — the opposite emphasis from a chat or content-generation workload. This calculator applies each model's own current input and output rate to get the balance right.
Why long documents can trigger long-context pricing
Some models charge a higher rate once a single request's input tokens cross a documented threshold. A long contract or a bundle of scanned pages can cross that threshold on its own, even with a simple schema — this calculator applies each model's own verified threshold and higher rate automatically when a document does.
What's not included: getting to processable text
T9 estimates LLM inference/token cost only. Not included: OCR vendor fees, PDF/image parsing, document-storage fees, vector databases, dedicated parser/ extraction-API services, or any other third-party fee.
Those steps are billed separately — often per page, not per token — by whatever OCR or document-conversion service turns your source file (a scanned PDF, a photo of a receipt) into text a model can read. This estimate begins once that text already exists.
Low / Likely / High explained
A short document, a minimal schema, few fields and records.
A typical document, standard schema, and typical field/record count. Plan against this number.
A long document, a detailed schema, many fields and records. Budget against this.

Example monthly data extraction costs
These worked examples use the same default assumptions as the calculator above — a medium-length document, standard schema, 10 fields, 1 record per document — with GPT-5.4 Mini. Only the number of documents per month changes between rows. Use the calculator above to model your own usage or a different model.
| Usage level | Documents / month | Low | Likely | High |
|---|---|---|---|---|
| Light usage | 100 | $0.1626 | $0.2730 | $0.4133 |
| Typical usage | 300 | $0.4878 | $0.8190 | $1.24 |
| Heavy usage | 2,000 | $3.25 | $5.46 | $8.27 |
And here's the per-document cost for three realistic document types — a simple form, an invoice with several line items, and a long contract — with GPT-5.4 Mini, each with its own document size, schema complexity, and field/record count:
| Document type | Low | Likely | High |
|---|---|---|---|
| Simple form | $0.000501 | $0.000855 | $0.001365 |
| Invoice (with line items) | $0.004344 | $0.007343 | $0.0116 |
| Long contract | $0.004851 | $0.007417 | $0.0112 |
Caveats
- These estimates use the same reference document-length and instruction-prompt token ranges as the site's document summary calculator, accurate to ±10–15% for plain English text.
- Per-field and per-record output-token figures are this project's own descriptive assumption, not a provider-published figure — no AI provider publishes a token-overhead spec for structured extraction, since it depends entirely on the schema and the field values themselves (a short code is cheaper than a long free-text note). Real output size varies by schema; use the calculator's field/record inputs to match your own schema as closely as possible.
- Each provider uses a different tokeniser. Actual token counts may differ ±5–10% between providers for the same content.
- Getting from a source file to processable text is not priced here. OCR vendor fees, PDF/image parsing, document-storage fees, vector databases, and dedicated parser/extraction-API services (often billed per page) are not included — this tool only estimates the language model's own input/output token cost once that text already exists.
- Prices shown are manually verified against each provider's official pricing page as of 2026-09-08. AI provider pricing changes frequently — verify at your provider's official pricing page before making budget decisions.
- The long-context pricing tier, where a selected model has one, is resolved against each document's own input size, never a monthly aggregate — a single long document can trip the higher rate even when most of your documents don't.
- The context-window warning above appears when a document's combined tokens exceed 80% of the selected model's context window — a safety margin before truncation or failure risk, not a hard limit at 100%.
