Editorial standards

SmartCalculators publishes educational calculators and guides. Pages are attributed to the organisation, not to invented individual authors, reviews, user counts or certifications.

Accuracy

Calculator formulas are documented on the page. Guides explain the idea and the limits of the model. We do not claim guaranteed investment returns. Government-linked rates are shown as editable assumptions until they are verified against a named source and date.

Tax and regulated products

Tax rules change. When tax calculators ship, each one will carry a last-updated date. Unverified rules will not be presented as current law. Users should confirm figures with official sources or a qualified professional.

Corrections

If you find an error in a formula or article, use the contact page. We will correct the calculation or the copy rather than leave a known mistake in place.
