Editorial policy

This page sets out how ToolkitHQ content is researched, written, checked, and corrected. It applies to every guide and every calculator explainer on the site. The short version: we explain the maths behind each tool, we name the formulas and sources, we check the copy against what the calculator actually does, and we correct mistakes openly.

What we publish

ToolkitHQ publishes two kinds of content. Calculator pages pair a working tool with an explanation of the formula, a worked example, and the limitations you should know about. Guides are longer articles that stand on their own and connect several tools under one topic. Both are written for a general reader who wants a defensible answer, not marketing copy.

How content is researched and written

Calculators are hand-written in JavaScript. The explanatory text is drafted with AI assistance, then reviewed and edited by a human before it is published. That review is not a formality: the reviewer checks that every worked example matches the calculator’s real output, that stated rates and categories are current and correctly attributed, and that the page does not claim a feature the tool does not have. Where a calculation depends on local rates or a professional’s judgement, the page says so rather than pretending the estimate is authoritative.

Sources and accuracy

We use recognised, published formulas rather than invented ones, and we name them: the standard amortization formula for loans, Mifflin–St Jeor for basal metabolic rate, World Health Organization bands for BMI, and published coverage rates for construction materials. Where a figure depends on a source that changes over time — tax rates, contribution limits, material prices — the page tells you to confirm it for your jurisdiction and date. Estimates are labelled as estimates.

AI assistance and disclosure

We use AI tools to help draft explanatory content, because they produce clear first drafts at a scale a solo operator could not match. We do not use them to decide whether a number is correct. Every page is checked by a human against the underlying formula and against the sources it cites, and pages are updated when the formula, rate, or source changes. If a page reads as generic or inaccurate, that is a failure of the review step, and we want to hear about it.

Independence and advertising

ToolkitHQ carries advertising and a one-time Pro upgrade; neither influences the content. Advertisers do not see or edit pages before publication, and we do not write copy to favour an advertiser. Where we ever add affiliate links, they will be disclosed on the page, and they will never change a calculation or a recommendation.

Corrections

When we find an error — or someone reports one — we fix it and update the page. Calculation errors are treated as a priority because a wrong number is worse than no number. If a correction changes a result materially, the page’s review date is updated so the change is visible.

Review and updates

Every calculator and guide shows the date it was last reviewed. We re-check content when a formula, rate, or source changes, and at other times as needed. The review date is not decorative: if it has moved, something on the page was examined.
