Editorial Policy

This page sets out the standards every calculator and article on CalcFree is held to. It applies to all content on the site.

What we publish

We build calculators for specific, real decisions — claiming a CIS refund, comparing umbrella and limited-company pay, budgeting a fencing job — rather than generic sums that already exist everywhere. A tool earns a place only if it does something genuinely useful and can be made accurate enough to trust.

How content is written

Explanations are written in plain English by a named author, with real worked examples and honest limitations. We don’t pad pages to chase keywords, we don’t make guarantees about outcomes, and we don’t dress estimates up as advice. Where a topic is complex, we say so and point to a professional.

How content is reviewed

Before publication, the calculation logic is checked against the relevant official source and tested with worked examples at typical and edge values. The written guidance is reviewed for accuracy and clarity. Every tool names its author and shows a last-reviewed date.

Independence

Our calculators and explanations are not influenced by advertisers. Advertising keeps the site free, but it does not shape which tools we build or what our guidance says.

Corrections

If we get something wrong, we fix it and update the last-reviewed date. See our Review, Sources and Methodology policies for the detail of how this works.
