Informational purpose only

The calculators and articles on EcomGauge are published for general information. They are not accounting, bookkeeping, tax, legal, investment or financial advice, and they are not a substitute for a qualified professional who can review your full circumstances.

Results depend on what you enter

Every output is arithmetic performed on figures you supply. If a cost is missing, estimated or entered in the wrong unit, the result will be wrong in a way the calculator cannot detect. Each tool lists the costs it includes and excludes — read that list before acting on a number.

No guarantee of outcomes

A calculator can tell you where a break-even point sits given your inputs. It cannot predict sales, ad performance, refund rates or supplier prices, and no result here should be read as a forecast or a promise of profitability.

Advertising and affiliate disclosure

The site may display advertising and may include affiliate links, from which it could earn a commission at no additional cost to you. Advertising will be visually distinct from editorial content and from the calculators themselves, and no commercial relationship influences the formulas, the inputs a tool accepts or the results it produces.

Errors and corrections

Formulas are tested and reviewed, with review dates published on each tool. If you find an error, please report it — corrections are made promptly and the review date is updated. The approach behind every calculation is documented in the methodology.
