Cost Per Lead (CPL) Calculator

Enter your ad spend and number of leads to get your cost per lead — essential for any home-services or B2B lead-gen campaign.

How to calculate CPL

CPL = Ad spend ÷ Leads. £1,000 for 50 leads is a £20 cost per lead. Then factor your lead-to-customer close rate to get true cost per customer.

If 1 in 4 leads becomes a customer, a £20 CPL means £80 to win a customer. Track both — cheap leads that never close aren’t cheap.

How do I calculate cost per lead?

Divide ad spend by the number of leads generated in the same period.

What’s a good cost per lead?

It depends on close rate and customer value — a £20 lead is great if customers are worth £1,000 and you close 1 in 4.
