Ad budget
calculator.
Work backwards from the customers you want to the clicks, leads and monthly ad budget it takes. The example numbers are placeholders: use your own cost per click and conversion rates.
Ad spend only. Management fees, creative and tools are separate.
Where to find your numbers
Cost per click varies a lot by industry, city and keyword. Google Ads Keyword Planner shows estimates for your exact keywords, and your own account history is better still. Landing page conversion rate is leads divided by visits to the page you advertise; GA4 shows both.
The two biggest levers are not the budget. Doubling your landing page conversion rate halves the budget you need, and so does doubling your close rate. That is why we fix tracking, the page and the follow-up before scaling spend.
