Dataset methodology
This page documents how the Calxo AI Calculator Formula Library is selected, structured, verified, versioned, cited, and prepared for GitHub and Zenodo archival releases.
Dataset version 2026.07.25 - Updated 2026-07-25

Sourced
The dataset includes Calxo AI calculators that expose a structured formula definition in the site catalog. Each row represents one calculator method and points back to the public calculator page where readers can inspect the live inputs, assumptions, result behavior, and source notes.
Rows are generated from working calculator definitions. A calculator enters the library when it has a formula name, expression, and worked example. Calculators without a stable formula entry are excluded until their method can be documented clearly.
Where a method depends on an official rate, threshold, regulatory rule, clinical reference, scientific relationship, or published source, the row inherits source metadata from the calculator source profile. Source-backed rows expose publisher URLs and the latest available verification date.
Dataset versions use date-style identifiers. A version changes when formula coverage, row structure, source coverage, public calculator URLs, or material formula/source assumptions change. The live Formula Library remains the canonical current version.
Field dictionary
The CSV and JSON distributions use stable field names so publishers can update snapshots without remapping their workflow.
| Column | Definition |
|---|---|
| slug | Stable calculator identifier used in Calxo URLs and internal references. |
| calculator | Public calculator title associated with the formula entry. |
| category | Primary calculator category such as Finance, Health, Math, Business, or Construction/Home. |
| formula_name | Human-readable name for the method or equation shown in the calculator. |
| formula | Formula expression as displayed for calculator users. Symbols are explained by the calculator page and worked example. |
| worked_example | Representative calculation using sample values to show how the expression is applied. |
| region | Geographic scope when the formula or calculator is jurisdiction-specific; otherwise Global or blank. |
| effective_period | Tax year, regulatory period, source year, or other period when the value is scoped to a specific time. |
| disclaimer | Calculator-specific caution covering assumptions, regulated use, or situations where independent verification is needed. |
| official_sources | Pipe-separated source publishers and URLs when the calculator is backed by official or reference sources. |
| calculator_url | Canonical Calxo AI URL where readers can inspect inputs, assumptions, sources, and the live calculator. |
| last_verified | Most recent date the formula, source profile, or calculator reference was reviewed. |
Calxo AI-created dataset metadata, field dictionaries, formula tables, and CSV/JSON downloads may be cited and reused for education, research, editorial reference, internal analysis, and publisher integrations with attribution to Calxo AI, the dataset title, version, and canonical URL.
License: Calxo AI Data Reuse Terms
Calculator datasets are reference metadata, not professional advice. Official-source rows can become outdated when laws, thresholds, rates, clinical guidance, product data, or agency pages change.
For regulated or high-impact use, cite and verify the original official source alongside Calxo AI.
Send formula, source, field, or verification issues to corrections@mail.calxo.ai.
Include the calculator URL, source URL, expected correction, and enough detail to reproduce the issue.
