Calculator standard
A calculator must identify the decision it supports, show its formula, label the period and units, explain assumptions and limitations, and include a worked example. Inputs are processed locally in the browser. A calculator is not presented as a tax return, legal conclusion or personalised professional recommendation.
Sources and changing rules
Rules, thresholds, rates and deadlines can change. Where they affect a result, Tool IQ links to a current primary or official source and states when the method was reviewed. Users should confirm material decisions with the relevant authority or a qualified adviser.
AI assistance
AI may assist with research organisation, drafting and quality checks. It is not treated as a source. Articles disclose AI assistance, changing claims require current primary evidence, and a publishing schedule never justifies thin or repetitive content.
Commercial independence
Calculators remain free. Partner recommendations are labelled as independent, affiliate or sponsored. Commercial relationships do not change a calculator result, and calculator inputs are never attached to a partner click.
Corrections and updates
Publication and modified dates reflect real work. We do not change dates merely to make a page look fresh. If a method or factual statement needs correction, the page is updated and rechecked before its modified date changes.
Scope and accountability
Tool IQ is independently operated by Anthony McMeekin in the United Kingdom and is built for UK and US small-business decisions, with separate regional routes where terminology or rules differ. The publisher is responsible for decisions about methods, sources, corrections and commercial disclosures. Questions about a page, source or correction can be sent through the contact page.
