How much do I need to spend to get X customers a month?

Work backwards from the customers you need. Give it a target, a close rate and a conversion rate, and it returns the budget required — and whether that budget is large enough for paid search to work at all.

Open the budget planner

After each result you can ask for a written breakdown by email. That is optional and it is the only thing an email address gets you — the numbers themselves are never withheld.
