Churn Rate for Advertising Technology (AdTech)
DIRECT ANSWER
Churn rate is the percentage of customers — or revenue — that a business loses in a defined period. Customer churn divides lost customers by starting customer count; revenue churn divides lost MRR by starting MRR. For SaaS, median annual gross revenue churn is roughly 10–14% for SMB-focused products and 6–10% for mid-market. For Advertising Technology (AdTech) companies, this matters because Third-party cookie deprecation has invalidated a decade of AdTech architecture — vendors built on cross-site tracking must completely rebuild their identity resolution layer, creating existential uncertainty that media buyers see in their targeting accuracy metrics today.
What churn rate means for Advertising Technology (AdTech)
AdTech marketing is credibility-driven: MRC accreditation, TAG Brand Safety certification, and IAB Tech Lab compliance with IABTCF and OpenRTB are prerequisites that must appear on the first marketing touchpoint — media buyers screen for them before opening a case study. The post-cookie identity resolution narrative is the current highest-resonance theme, but it requires specificity: 'privacy-preserving identity' without a defined methodology (clean rooms, data clean room interoperability, probabilistic vs. deterministic matching) generates eye-rolls from technical buyers. Third-party measurement validation (DoubleVerify, IAS, MOAT integration) is a table-stakes marketing claim that differentiates nothing; what differentiates is an independent incremental measurement study showing real lift on the buyer's category.
For Advertising Technology (AdTech) teams the relevant marketing pains are: Third-party cookie deprecation has invalidated a decade of AdTech architecture — vendors built on cross-site tracking must completely rebuild their identity resolution layer, creating existential uncertainty that media buyers see in their targeting accuracy metrics today; Ad fraud consumes an estimated $100B+ annually — IVT (invalid traffic) rates in open programmatic can reach 20–40%, making measurement trust a prerequisite to any media investment conversation; Google's ad stack dominance (Search, Display, YouTube, DV360, GA4, CM360) creates a dependency that media agencies and brands simultaneously rely on and resent — alternatives must prove reach AND measurement equivalence against a vertically integrated incumbent; Agency holding company consolidation (Publicis, WPP, IPG, Omnicom) is centralizing technology decisions at the trading desk level, making individual agency relationships less valuable and enterprise trading desk relationships more critical; Supply path optimization (SPO) has made publisher monetization more complex — SSPs that can't prove curated, fraud-free inventory at competitive CPMs are losing publisher relationships to those that can.

Calculating and Interpreting Churn
The standard formula is: churn rate = (customers lost during period) ÷ (customers at start of period). A company that starts January with 500 customers and ends with 475 has a 5% monthly churn rate — which compounds to roughly 46% annual attrition, a figure that makes growth extremely difficult to sustain. This is why monthly churn above 2% for a SaaS product is generally treated as a structural problem requiring intervention, not a normal operating variable.
Revenue churn (also called MRR churn or gross revenue churn) is often more informative than customer churn because it weights losses by account size. A company can lose 10% of customers but only 3% of MRR if the churned accounts were disproportionately small. Net revenue retention (NRR), which accounts for expansion revenue from remaining customers, is the inverse signal — a healthy SaaS business typically shows NRR above 100%, meaning existing customers expand faster than others churn.
