How to Calculate Cost Per Lead (CPL): Complete Guide with Examples

How to Calculate Cost Per Lead (CPL)

Cost Per Lead (CPL) is calculated by dividing your total marketing spend by the number of leads generated:

CPL Formula:

Cost Per Lead = Total Marketing Spend ÷ Number of Leads Generated

Basic CPL Calculation Examples

Example 1: Facebook Ads Campaign

• Ad spend: $500
• Leads generated: 25 leads
• CPL: $500 ÷ 25 = $20 per lead

Example 2: Google Ads Campaign

• Ad spend: $1,200
• Leads generated: 40 leads
• CPL: $1,200 ÷ 40 = $30 per lead

Example 3: Content Marketing

• Content creation cost: $2,000
• Leads generated: 100 leads
• CPL: $2,000 ÷ 100 = $20 per lead

Customer Lifetime Value vs CPL

Compare CPL to customer value:

CPL Efficiency = Customer Lifetime Value ÷ Cost Per Lead
