These three calculators answer the questions we hear most from businesses that run their own Google Ads: is this month's spend on track, what return do the ads need before they pay for themselves, and what is one enquiry actually worth to me? Each one uses your own margins and numbers, runs in your browser, and stores nothing.
They are single-decision tools on purpose. Ads Toolbox itself runs 17 checks like these against a connected Google Ads account every day, tells you in plain English what is wasting budget, and changes nothing without your OK. If a calculator shows you a problem, the product shows you which campaign is causing it.
