Data Extraction Field Density Calculator
Select how many fields you need, whether you’re pulling from tables or paragraphs, and if you have nested or cross-page references. Get an extraction complexity tier, validation intensity, and suggested model type.
Extraction setup
Field density & structure
Approximate number of distinct fields to extract per document.
Where do most fields come from?
Do you need to extract fields inside repeating blocks or nested structures?
Do values or tables span multiple pages or reference other pages?
Extraction complexity tier
Low
Validation intensity required
Minimal
Spot checks or sampling; rules or small models usually sufficient.
Suggested model type
Small / rules or GPT-4o-mini — template-based or few-field extraction.
Great for
- Invoice automation
- Insurance claims
- KYC document processing
About this calculator
This calculator helps you scope extraction complexity for invoices, forms, claims, and KYC. You specify field count, whether data lives in tables or paragraphs, and if you have nested or cross-page references. The result is a complexity tier (Low through Very High), validation intensity, and a suggested model type—so you can plan schema design, validation, and human-in-the-loop where needed.
For PDF-level complexity (layout, OCR), use the PDF Complexity Score Calculator. For processing cost, use the Document Processing Cost Calculator.
Complexity tier and validation
| Complexity tier | Validation intensity | Typical use |
|---|---|---|
| Low | Minimal | Few fields, template-based or table extraction; light checks. |
| Medium | Standard | Structured forms, moderate field count; schema and sampling validation. |
| High | High | Tables, mixed layout, nested or cross-page; more sampling and review. |
| Very High | Critical | Many fields, nesting, cross-page; schema enforcement and human-in-the-loop. |
