Editorial Mission
The editorial mission of FivoTools is to provide useful, accessible utility tools and explanatory reference content. People use our calculators to plan budgets, compare paycheck figures, estimate construction materials, and manage independent client work. We show methods, assumptions, and limitations so readers can assess whether a result fits their situation.
The 8-Step Content & Verification Lifecycle
Our review process for tools and guides includes these checks where they apply:
- Task Definition: We identify a real, practical user task and map the exact user inputs and mathematical outputs required.
- Source Selection: We consult relevant primary sources and identify estimates and assumptions in the published explanation.
- Engine Isolation: Pure mathematical algorithms are implemented separately from the UI layer to eliminate side-effects and presentation bugs.
- Fixture Checks: Automated tests compare selected inputs and expected outputs and cover relevant boundaries.
- Rule-sensitive Content: Legal, tax, and rate-based content identifies its jurisdiction or source where applicable and should be checked against current official guidance.
- Example Checks: Worked examples are checked against the corresponding tool using the stated inputs when an interactive tool exists.
- Transparent Publication: Tool pages explain their formulas, assumptions, limitations, and a review date where one is provided.
- Corrections: User reports can be sent through the contact page and are reviewed against the relevant sources and calculation behavior.
Responsible Use of Artificial Intelligence
Modern AI coding assistants are utilized during our engineering workflow to support code generation, design system scaffolding, and draft structuring. However, we enforce strict human guardrails:
Corrections & Retractions Policy
When an error or discrepancy is reported, we review it against relevant sources and calculation behavior. If a material issue is confirmed, we update the affected content or tool and its related example or test where appropriate:
- We identify the source, assumption, input, or calculation step involved.
- We update the affected formula, explanation, or reference data when a defect or outdated value is confirmed.
- Substantive corrections are recorded with an updated review timestamp on the relevant tool page.
- We do not penalize or ignore users who find bugs - we treat error reports as essential contributions to product reliability.
Commercial Independence
FivoTools does not currently display ads. If commercial relationships are introduced, they should be disclosed and kept separate from calculation formulas, source selection, and tool recommendations.
