Editorial Policy

Last updated: July 13, 2026

This Editorial Policy explains how AjaxCalculators develops, tests, publishes, reviews, and updates its calculators, converters, educational explanations, and related website content.

1. Our Editorial Purpose

AjaxCalculators aims to provide practical calculators, converters, and supporting explanations that are understandable, accessible, and useful for everyday educational and informational purposes.

Our objective is to help users understand:

  • What a calculation measures;
  • Which inputs are required;
  • Which formula or method is used;
  • How the result should be interpreted;
  • Which assumptions affect the result; and
  • When professional or official guidance may be necessary.

2. Ownership and Editorial Responsibility

AjaxCalculators is independently owned, developed, and maintained.

Calculator logic, website functionality, and supporting page content are produced and maintained internally under the AjaxCalculators brand. AjaxCalculators accepts publishing responsibility for the content and tools made available through this website.

We do not describe content as medically reviewed, professionally verified, independently audited, or expert reviewed unless that specific review has genuinely occurred and is clearly identified on the relevant page.

3. Calculator Development Process

Our normal calculator-development process includes:

  1. Defining the purpose and intended scope of the calculator;
  2. Researching the relevant formula, method, guideline, or conversion relationship;
  3. Identifying required inputs, units, assumptions, and limitations;
  4. Implementing the calculation logic;
  5. Testing standard inputs and known examples;
  6. Testing zero, decimal, negative, missing, extreme, and invalid values where relevant;
  7. Checking unit conversions and rounding behaviour;
  8. Reviewing result labels, explanations, and warning messages;
  9. Adding educational content, examples, and references where appropriate; and
  10. Publishing updates when errors, clearer methods, or revised standards are identified.

4. Formula and Result Testing

Before publication or after a significant revision, calculator results are checked, where applicable, using one or more of the following methods:

  • Manual worked examples;
  • Known mathematical or scientific results;
  • Official formula documentation;
  • Independent calculation methods;
  • Published examples from authoritative sources; and
  • Boundary and invalid-input testing.

Testing reduces the risk of error but cannot guarantee that every calculator will be accurate in every possible circumstance. Users should review the displayed method, units, assumptions, and limitations before relying on a result.

5. Sources and References

Where references are relevant, we aim to prioritise sources in approximately the following order:

  1. Government agencies and official statistical organisations;
  2. Recognised medical, scientific, financial, or professional organisations;
  3. Peer-reviewed research and academic publications;
  4. Established textbooks and educational institutions;
  5. Official technical standards and manufacturer documentation; and
  6. Other reputable educational or industry sources.

References are provided to support formulas, definitions, guidelines, classifications, or important assumptions. A link to an external source does not mean that the source endorses AjaxCalculators.

6. Supporting Calculator Content

Where appropriate, calculator pages may include:

  • An explanation of what the calculator does;
  • Instructions for using the inputs;
  • The principal formula or method;
  • A worked example;
  • Interpretation guidance;
  • Assumptions and limitations;
  • Relevant reference material;
  • Frequently asked questions; and
  • A method for reporting an error.

The level of explanation may vary depending on the calculator’s complexity, subject, and potential consequences of misuse.

7. Health and Medical Calculators

Health-related calculators are provided for general education, screening awareness, and informational use. They are not medical devices and do not diagnose, treat, prevent, or cure a medical condition.

Health classifications and reference ranges may differ between countries, organisations, populations, age groups, laboratories, and clinical guidelines. Where relevant, we aim to identify the guideline or method used.

Users should discuss health concerns, symptoms, medication decisions, pregnancy matters, child development, or abnormal results with an appropriately qualified healthcare professional.

8. Finance and Tax Calculators

Financial calculators provide estimates based on the values and assumptions entered by the user. Actual rates, taxes, fees, investment returns, lender requirements, inflation, regulations, and market conditions may differ.

Financial content is not personalised investment, tax, accounting, insurance, credit, or legal advice. Users should verify important decisions with official documents or an appropriately qualified professional.

9. Construction, Engineering, and Technical Calculators

Construction, engineering, scientific, and technical calculators may use simplified conditions or idealised formulas. Real projects can be affected by material properties, tolerances, environmental conditions, safety factors, building codes, professional standards, and site-specific requirements.

Results should not replace approved drawings, manufacturer instructions, regulatory requirements, laboratory testing, or professional engineering and safety assessments.

10. Use of Software and AI-Assisted Tools

Software and AI-assisted tools may be used during development to support tasks such as research organisation, drafting, coding, formula implementation, unit checks, formatting, testing, and identification of potential errors.

AI is not integrated into the calculators themselves. Calculator inputs and results are not submitted to AI systems for processing, and calculator data is not stored or used by AI through the calculator tools.

AI-assisted or software-generated output is not treated as authoritative by itself. AjaxCalculators remains responsible for the published calculator logic, explanatory content, limitations, references, and corrections.

11. Advertising and Editorial Independence

AjaxCalculators may display advertising to support website operation and maintenance.

Advertising does not determine a calculator’s formula, result, conclusion, warning, or editorial position. Advertisers do not receive permission to change calculator results or supporting explanations.

Advertisements and sponsored material, where present, should be distinguishable from calculator and editorial content.

12. Updates and Revisions

Calculator pages may be updated when:

  • A calculation or coding error is identified;
  • A formula, guideline, rate, or standard changes;
  • Instructions or explanations require clarification;
  • New units or features are added;
  • Sources or references need to be updated;
  • Accessibility or usability is improved; or
  • A technical compatibility issue is corrected.

Updates are made when they improve the accuracy, clarity, functionality, reliability, or usability of a calculator or its supporting content. Pages are not modified merely to create the appearance of freshness.

13. Corrections

Despite testing and review, errors may occur. We welcome clear and specific correction reports.

A useful report should include:

  • The calculator or page URL;
  • The values entered;
  • The result displayed;
  • The result you expected;
  • The reason you believe the result is incorrect; and
  • A relevant source or worked calculation, where available.

Reported issues may be reproduced and investigated before a change is made. Material errors will be corrected when confirmed. Minor differences caused by rounding, assumptions, unit conventions, or alternative formulas may be explained rather than changed.
