How these tools work
Each tool works backwards from a result you want, such as a number of leads, a return on ad spend or hours saved, to the budget or effort it takes. The formula is written out on the tool's page, so you can check the maths or rebuild it in a spreadsheet.
Where a tool fills in a default, such as an industry's average cost per click, the figure comes from a published report or an official source, and the page names it with the date we checked it. Defaults are a starting point. Your own account data, once you have a few weeks of it, is always better.
We do not publish our own prices, so no tool quotes what Shahjan and Digital would charge. The cost figures you see are the platform's or the report's, labelled as theirs. Everything runs in your browser: nothing you type is stored or sent unless you choose to send us your numbers for a second opinion.
