Cost per booked call calculator

Cost per lead hides where the money leaks. Enter your funnel and see what each step really costs, from the first form to the signed sale.

How to read the result

Look for the biggest drop between two steps. A low booking rate points at slow replies or a weak offer. A low show rate points at missing reminders or bookings made too far ahead. A low close rate is usually a sales or targeting problem.

Each fix lowers the cost of a sale without touching the ad budget. That is why we judge campaigns on cost per booked call and cost per sale, as our article on why cost per lead is the wrong number explains.

Frequently asked questions

Where do I find these numbers?

Spend comes from the ad platforms. Leads, bookings, shows and sales should come from your CRM, where each lead has a status. If you cannot count shows today, that is the first thing to fix; our lead handling service starts there.

Should I count every lead?

Count every lead in the period, including duplicates and spam, then run it again with qualified leads only. The gap tells you how much of the budget buys noise.
