Understanding Cost Per Lead

Cost per lead (CPL) is a fundamental metric for measuring marketing efficiency. It tells you what you're paying to get someone interested enough to contact you.

CPL = Marketing Spend ÷ Number of Leads

Example: $2,000 spent ÷ 40 leads = $50 CPL

Cost per Customer = CPL ÷ Close Rate

Example: $50 CPL ÷ 25% close rate = $200 cost per customer

Max Affordable CPL = AOV × Gross Margin × Close Rate

Example: $500 × 50% margin × 25% = $62.50 max profitable CPL

Revenue vs. Profit: The critical difference

Most businesses make the mistake of comparing CPL to revenue instead of gross profit. Always factor in your cost of goods/services. At $125 CPL with 50% margin, you're losing money even if revenue covers ad spend—because you still have service delivery costs.
