Why trust Retail Toolkit?
Six concrete commitments that turn "another calculator site" into a resource retail teams rely on.
Real retail experience
Content is produced and reviewed by the Retail Toolkit Editorial Team — operators with backgrounds in supermarket management, retail finance, waste reduction and labour planning.
Meet the team →Transparent methodology
Every calculator publishes the formula it uses, links to a methodology page explaining the accounting conventions, and cites the benchmarks it compares against.
Read methodology →Quarterly review cycle
Calculators and guides are reviewed at least every quarter and re-reviewed immediately when formulas or benchmark data change.
Editorial policy →Open corrections policy
Spot an error? Tell us via the contact page. Verified corrections are made promptly and the page's last-updated date is revised.
Report an issue →Calculator inputs stay private
Numbers you enter into calculators are processed in your browser. We do not send your calculator inputs to our servers and we do not store them.
Privacy policy →Free for everyone
Calculators, the glossary and educational guides are free to use — no signup required for the calculations themselves.
