Why EcomGauge exists

Revenue is the number every store dashboard shows first. It is also the number that tells you least about whether the business works.

The problem this site is aimed at

Ecommerce operators make daily decisions — raise the price, keep the campaign running, drop the supplier — that depend on economics no dashboard reports. Ad platforms report revenue and ROAS. Store platforms report sales and gross margin. Neither shows what a single order actually leaves behind once the product, the shipping, the fees and the traffic are paid for.

EcomGauge exists to close that gap with calculators that are free, fast and auditable: the formula is on the page, the assumptions are listed, and the arithmetic is simple enough to check in a spreadsheet.

How the tools are built

Every calculator publishes its formula, states what it includes and excludes, and carries the date it was last reviewed. Calculation logic is tested separately from the interface, including the awkward cases — zero contribution, costs above revenue, empty fields — which are the ones most calculators get wrong. The full approach is in the methodology.

No accounts, no data collection

Nothing here requires signing up, and the figures you type never leave your device. Each calculator runs entirely in the browser, which is both a privacy decision and a speed one. See the privacy policy.

How the site is funded

The calculators are free to use and are intended to stay that way. The site expects to be supported by advertising and, where genuinely relevant, affiliate partnerships; some advanced features may be offered as a paid product later. Any advertising will be clearly distinguishable from the tools and the editorial content, and no partnership will change what a calculator outputs.

What this site is not

It is not an accountant, a tax adviser or a financial adviser, and it does not hold itself out as one. The calculators are informational aids for operators who want to understand their own numbers. Read the disclaimer before relying on any output.
