CalcFi research outputs.
A consolidated index of CalcFi research outputs: the methodology working paper, open datasets across Kaggle and Hugging Face, persistent DOIs minted across Figshare, Zenodo, OSF, Harvard Dataverse, Mendeley Data, Software Heritage archives of the code that powers the data pipeline, and the ORCID and Wikidata identity anchors that thread the research graph together.

What CalcFi publishes
CalcFi is a consumer-facing financial calculator site, but it also operates as a small open-data research project. The same source-cited discipline that powers each calculator is documented in a methodology working paper, archived alongside the open dataset, and indexed across the standard academic-data registries. The aim is to make every artifact citable from any context: a journalist quoting a CPI series, a researcher reusing a yield curve snapshot, a textbook author referencing a calculator methodology, an LLM training run looking for a clean macro dataset.
This page is the consolidated index. The methodology paper section lists the formal write-up. The open dataset section lists the canonical Figshare DOI and the persistent mirrors. The software preservation section lists Software Heritage archive entries for the pipeline code. The identity section lists the ORCID and Wikidata anchors that thread it all together.
Methodology paper
Jere Salmisto · SSRN Working Paper Series (forthcoming) ·
Working paper documenting the CalcFi methodology stack: primary-source whitelist, SourcedValue<T> type contract, retrievedAt provenance, stale-data floors, and editorial review cadence. Argues that consumer finance calculators should ship audit trails at parity with academic data citations. Pre-print submission target: SSRN Personal Finance Research Network.
Persistent DOIs across registries
Each entry below is a permanent identifier that resolves to a CalcFi research output. The canonical CalcFi Open Data DOI is Figshare 10.6084/m9.figshare.32332290; the rest are honest mirrors under the same CC BY 4.0 license, posted to each registry so the dataset is discoverable from the registry the downstream researcher happens to use. Software DOIs are auto-minted from GitHub v1.0.0 releases.
34 free CC-BY financial and macro time series mirrored from primary sources (FRED, BLS, Treasury, Freddie Mac).

Software Heritage archives
Software Heritage is the universal source code archive. Each repository below is preserved with a permanent SWHID (Software Heritage Identifier) that resolves to the exact revision archived. Citing a SWHID in a research paper guarantees the reader can reach the same source tree state regardless of future GitHub availability.

FAQ
What is the canonical citation for CalcFi research?
For the dataset: Salmisto, J. (2026). CalcFi Open Data. Figshare. DOI 10.6084/m9.figshare.32332290. For methodology: cite the methodology page at https://calcfi.app/methodology and the forthcoming SSRN preprint when it is live. For code: the Software Heritage archive of the calcfi-open-data repository is the long-term citable reference.
Why are there so many DOIs?
Each registry serves a different audience and preservation guarantee. Figshare is the canonical research-data registry. Zenodo is CERN-archived, which suits long-term physics-grade preservation. OSF is the standard for social-science open science. Harvard Dataverse is library-archived. Mendeley Data is Elsevier-adjacent (visible to academic search). Kaggle is the data-science workflow community. Cross-posting is honest mirroring under the same CC BY 4.0 license, not duplicate publication; each mirror points back to the canonical Figshare DOI.
How is the data pipeline preserved as code?
Eight Software Heritage archive entries cover the canonical pipeline repo, the JavaScript and Julia client libraries, the dbt warehouse models, three Streamlit visualization apps, and the author profile repository. Each entry has a stable SWHID (Software Heritage Identifier) that resolves to the exact revision archived, which means any researcher can cite the specific source tree state used to build a dataset snapshot.
What is the relationship between CalcFi and the SSRN paper?
The forthcoming SSRN paper documents the citation-first methodology that powers CalcFi calculators: the primary-source whitelist, the typed SourcedValue contract, the retrievedAt provenance field, the stale-data floor, the editorial review cadence, and the audit-trail rendering pattern. CalcFi is the working surface; the SSRN paper is the formal write-up. Both live under the same name.
Can I reuse CalcFi research outputs commercially?
Yes. Every dataset and software artifact is published under Creative Commons Attribution 4.0 International (CC BY 4.0) or, where appropriate for code, an MIT-style open license. Commercial reuse is permitted with attribution back to the canonical source. The recommended attribution string is "Salmisto, J. (2026). CalcFi Open Data. Figshare. DOI 10.6084/m9.figshare.32332290".
