Who publishes UseCalcForge

UseCalcForge is a small independent publication, not a company with a newsroom. Articles and calculator documentation are published under the UseCalcForge editorial desk, which is the working name for the same small group of people who build the tools. We use a desk byline rather than inventing individual author personas, because a fabricated expert with a stock photograph would be worse than an honest collective one.

That means we do not claim individual subject-matter credentials. We are not licensed financial advisers, clinicians or professional engineers, and we do not present ourselves as any of those. What we do is implement published formulas carefully, name our sources, and say plainly where a tool’s limits are. Everything on this site should be read in that light. If you need advice for a decision that carries real consequences, get it from a qualified professional.

How a calculator is checked before it goes live

Every tool follows the same four steps, and a tool that fails any of them does not publish.

1. Start from a published formula. We implement an established equation rather than deriving our own — the standard amortization formula, Mifflin–St Jeor for BMR, the defined SI relationships for unit conversion. Where a tool uses a specific named equation, the page says so.
2. Test against a known answer. The implementation is run against a worked example whose correct result is already established: a textbook problem, an official example, or a figure published by whoever owns the standard. If our output does not reproduce it, the tool is wrong and does not ship.
3. Write down the limits. Before publishing we identify what the tool cannot account for — a lender’s rounding, your specific tax allowances, an individual’s body composition — and state it on the page rather than leaving the reader to assume precision we cannot deliver.
4. Date anything that expires. Tax brackets, contribution limits and printing costs all change. Where a tool depends on a figure tied to a year, that year appears on the page so you can judge whether it is still current.

What we will not do

These are commitments, and they are specific because vague ones are worthless:

• We do not claim certification, auditing or endorsement by any standards body. Where we reference a published standard, we are describing the specification our maths follows — not asserting that the organisation has reviewed our work.
• We do not invent precision. No accuracy percentages we have not measured, and no benchmark claims we cannot evidence.
• We do not publish articles written entirely by an automated system and passed off as human reporting.
• We do not accept payment to alter a calculation result, a recommendation, or the substance of an article.

Corrections

We correct errors rather than quietly deleting the page. If a mistake changed the substance of what a reader would have concluded — a wrong formula, a wrong figure, a claim we could not support — we fix it and say so.

We hold ourselves to this in public. In 2026 this site carried claims that calculator inputs never left the reader’s browser. That was true for some tools and not for others, and the privacy policy has been rewritten to describe both cases accurately. Pages also referenced standards bodies in ways that implied verification we had not obtained; those claims have been removed. We would rather document that than pretend it never happened.

Advertising and independence

This site is free to use and is funded by advertising and, on some pages, affiliate links. Advertising is sold programmatically: we do not choose which advertisers appear, and no advertiser sees or influences our content before it publishes. Where a link earns us a commission it is disclosed on the page carrying it. No calculator result, ranking or recommendation is affected by a commercial relationship — the arithmetic does not know who is paying.
