What this site promises, and what it does not
Every number on these pages is either your own, entered into a calculator that runs in your browser, or a worked example labelled as one. There are no income claims, no borrowed results and no made-up benchmarks. The tools help you see your costs clearly and decide what to fix first; what happens next depends on your store.
