# Cost per lead vs cost per closing: the metric switch that matters
A brokerage in Austin ran a Facebook campaign that generated leads at $8 each. The marketing director celebrated. Six months later, the brokerage had spent $40,000 on that campaign, closed two deals, and quietly bled money on every one of them. Cheap leads. Expensive customers.

This lesson walks through why cost per lead (CPL) is a vanity metric on its own, how to trace spend all the way to cost per closing, and what benchmarks tell you whether your funnelfunnelThe customer journey from awareness to purchase, typically Awareness, Interest, Consideration, Decision, Action, with prospects narrowing at each stage. is healthy or hemorrhaging cash.
Cost per lead (CPL) is simply: total campaign spend divided by number of leads generated. A "lead" in real estate usually means a form fill, a phone call, or a portal inquiry (from sites like Zillow, Realtor.com, or in Europe, Idealista and Immobiliare.it).
CPL is easy to game. Broad targeting, aggressive lead magnets ("free home valuation!"), and portal syndication can flood your CRMCRMCustomer Relationship Management: software and strategy to manage and analyse customer interactions throughout their lifecycle.View full definition → (customer relationship managementcustomer relationship managementCustomer Relationship Management: software and strategy to manage and analyse customer interactions throughout their lifecycle.View full definition → system) with cheap contacts. But volume hides quality. A $8 lead from a boosted Facebook post might be a curious renter who will never buy. A $95 lead from a targeted Google Ads campaign for "sell my house fast [city]" might be a motivated seller ready to sign in three weeks.

Cost per closing (CPC, not to be confused with cost-per-click, also abbreviated CPC, so context matters) measures total marketing spend divided by the number of completed transactions (closings) attributable to that spend.
The formula:
Cost per Closing = Total Marketing Spend / Number of Closings AttributedWorked example:
If the brokerage's average commission on a closed deal is $9,000, that campaign lost roughly $11,000 per closing, before accounting for agent split, overhead or referral fees.

Lifetime value (LTV) in real estate is not just one commission. It includes:
