Discuss this with the teamHow the calculators work
They run in your browser
Nothing goes to a server until you press the request button yourself. Only your browser remembers your last values.
The formulas are open
Under each calculator are the formulas and assumptions in plain words. You can check them on a calculator or in a spreadsheet.
Assumptions are labelled
Where an assumption is unavoidable (share of lost leads, share of work for an agent), you set it. Niche examples are illustrative, not our results.
Questions
Are the calculators free?
Yes, no sign-up and no email. Your calculation reaches us only if you press “Discuss this with the team” and send the form yourself.
How accurate is the result?
Exactly as accurate as your numbers. The formulas are simple and open, but real cost per click, conversion and timelines only show on your own data, which is what we look at in an audit.
Where do Senator Media prices in the calculations come from?
From the service pages of this site: these are “from” prices, the final figure comes after the review. Where there is no exact figure, the calculator says “on request” instead of making one up.
Can I send you my calculation?
Yes. The button under the result opens the request form with the calculation already in the message. We reply within two hours during working hours.
