Cost-Per-Lease (CPL)

Cost-Per-Lease (CPL) is calculated by dividing total marketing spend (for a channel, campaign, or vendor) by the number of signed leases attributable to that spend over the same period. It is the definitive performance metric for multifamily marketing because it connects advertising investment directly to the outcome that drives revenue: a signed lease, not a form fill, a phone call, or a tour.

Most surface-level marketing metrics, including impressions, clicks, leads, tours, are proxies for performance, not proof of it. CPL cuts through that noise by anchoring campaign evaluation to the signed lease, which is the only outcome that affects occupancy, revenue, and NOI. It enables apples-to-apples comparisons across channels (paid search vs. ILS vs. social) and vendors, making budget reallocation decisions more defensible and data-driven. Calculating CPL accurately requires clean attribution - specifically, connecting CRM lease data back to the marketing source that originated the prospect. As leasing cycles lengthen and attribution complexity grows across channels, teams that invest in accurate CPL tracking have a significant analytical advantage over those relying on cost-per-lead as a performance proxy.
