How the calculator works
The tool uses your monthly budget, estimated cost per lead, answer rate, conversion rate and average customer value.
Booked customers = monthly ad spend ÷ cost per lead × answer rate × conversion rate

Budget planning
How much should you budget?
Start with the number of customers you want. Work backwards from your sales conversion rate and estimated lead cost.
Required ad spend = target customers ÷ answer rate ÷ conversion rate × estimated cost per lead
Ad spend is separate and paid directly to Google. If you want us to run the account, our Google Local Services Ads management is from £500 a month, the fee the calculator starts with.
