Disclosures
Review Margin101 ownership, editorial independence, commercial relationships, privacy practices and educational boundaries for small-business content.
Effective Date: 12 July 2026
Why this page exists
Margin101 is an independent project built and maintained by its founder, Duc Nguyen X. It is not an accounting, tax, legal or financial-advice business.
1. Editorial independence
Formula logic, assumptions and outputs are determined by the product specification and evidence. No advertiser, affiliate or sponsor may purchase a favourable result.
2. Affiliate disclosure
- Margin101 currently has no active affiliate relationships.
- Any future affiliate link will be labelled near the link, not only on this page.
- Calculator outputs will not be gated behind affiliate clicks.
3. Advertising disclosure
Margin101 does not currently run programmatic display advertising. Any future advertising must remain outside calculator controls and may not influence calculations.
4. Sponsorship policy
Margin101 does not currently publish sponsored content. Any future sponsorship will be clearly labelled and kept separate from formula and evidence decisions.
5. Use of business data
Calculator inputs and outputs stay in the browser. Optional saved plans are local conveniences, not bookkeeping records or secure backups. Anonymous analytics sends only allowlisted categorical identifiers to the product-owned events.margin101.com endpoint; it never sends calculator inputs, outputs or financial values.
6. Professional boundary
Using a tool, guide or contact email does not create an accountant-client, tax-agent-client, solicitor-client, adviser-client or other professional relationship.
7. Contact and corrections
