About the Lead Conversion Rate Calculator

Lead conversion rate is where marketing and sales meet: of all the leads handed over, how many actually became customers? It is the multiplier that turns a cost per lead into a cost per customer, and the number that settles whether a channel is producing quality or just volume.

Enter leads and conversions to get the rate straight away, along with how many leads it takes on average to land one customer. Add the revenue a converted lead is worth and the calculator also shows revenue per lead — the figure to compare directly against your cost per lead.
