Customer Acquisition Cost (CAC) Course

Lesson 1 • Key Terms and Related Metrics

Precise vocabulary prevents calculation errors and miscommunication. Students map CAC to adjacent metrics used throughout the course.

Lesson 2 • Common Misconceptions About CAC

Misapplied CAC leads to flawed strategy. Identifying frequent errors builds critical thinking before students attempt their own calculations.

Lesson 3 • Defining CAC and Its Purpose

CAC is defined as total acquisition spend divided by new customers gained. This baseline anchors every calculation and decision covered later.

Lesson 1 • Defining the Measurement Period

Mismatched time windows distort CAC. Students learn to align cost and customer-count periods for consistent results.

Lesson 2 • Identifying All Acquisition Costs

Accurate CAC requires capturing every relevant expense. This section maps the full cost inventory before any formula is applied.

Lesson 3 • Building a CAC Calculation Template

A reusable template standardises CAC reporting across teams. Students construct a structured model they can adapt to any business.

Lesson 4 • Handling Data Gaps and Estimates

Real data is often incomplete. Students apply principled estimation techniques to produce defensible CAC figures despite missing inputs.

Lesson 1 • Offline and Assisted Conversion Tracking

Many acquisitions involve offline or multi-step interactions that standard tracking misses. Students capture these touchpoints to avoid understating CAC.

Lesson 2 • Attribution Models Overview

Attribution assigns credit for conversions to marketing touchpoints. Choosing the right model directly determines which costs enter the CAC formula.

Lesson 3 • Tracking Infrastructure Setup

Accurate attribution depends on consistent event tracking across channels. Students audit and configure the data layer that feeds CAC reporting.

Lesson 4 • Privacy Constraints and Data Collection

Consent requirements and cookie restrictions limit tracking options. Students adapt attribution approaches to remain accurate within privacy boundaries.

Lesson 1 • The LTV:CAC Ratio Explained

The LTV:CAC ratio is the primary profitability signal for acquisition spend. Students interpret ratio thresholds and their strategic implications.

Lesson 2 • Balancing CAC and LTV Across Segments

Different customer segments carry different LTV:CAC profiles. Students allocate acquisition budgets based on segment-level ratio analysis.

Lesson 3 • Customer Lifetime Value Fundamentals

LTV quantifies the total revenue a customer generates over their relationship with the business. This section establishes LTV models before linking them to CAC.

Lesson 1 • Organic and Content Channel CAC

Organic channels carry indirect costs that are often underreported. Students allocate content and SEO costs to produce honest organic CAC figures.

Lesson 2 • Cross-Channel CAC Comparison

Comparing channels on CAC alone ignores LTV differences. Students build a multi-metric scorecard that ranks channels on profitability, not just cost.

Lesson 3 • Events, Outbound, and Field Sales CAC

High-touch channels carry large fixed costs spread across few conversions. Students apply appropriate cost allocation to avoid inflating or deflating CAC.

Lesson 4 • Referral, Affiliate, and Partnership CAC

Referral programmes and affiliates shift cost structure to variable commissions. Students calculate and compare these channel CAC figures against paid alternatives.

Lesson 1 • Funnel Efficiency and Lead Nurturing

Leaky funnels inflate CAC by wasting top-of-funnel investment. Students design nurture sequences that move prospects to conversion more efficiently.

Lesson 2 • Pricing and Offer Optimisation

Offer structure affects both conversion rate and customer quality. Students test pricing and incentive designs that lower CAC while protecting LTV.

Lesson 3 • Budget Reallocation for CAC Efficiency

Shifting spend toward lower-CAC channels compounds savings over time. Students apply a data-driven reallocation process using channel analysis from Chapter 5.

Lesson 4 • Audience Targeting and Segmentation

Reaching high-intent, high-LTV prospects lowers wasted spend. Students refine targeting parameters to improve CAC across paid and organic channels.

Lesson 1 • External Benchmarking Sources

Industry data contextualises internal CAC against peers. Students evaluate external benchmarks critically and apply them without over-indexing.

Lesson 2 • CAC Reporting Cadence and Governance

Consistent reporting prevents metric drift and ensures accountability. Students define ownership, frequency, and review protocols for CAC reporting.

Lesson 3 • Communicating CAC to Stakeholders

CAC data must be translated into business implications for non-technical audiences. Students frame CAC findings as investment decisions, not accounting outputs.

Lesson 4 • CAC Dashboard Design

A well-designed dashboard surfaces CAC trends and anomalies at a glance. Students structure dashboards for different audience levels and decision needs.

Lesson 1 • CAC in Growth Planning

Growth targets imply specific CAC budgets and channel mixes. Students reverse-engineer acquisition plans from revenue goals using CAC as the anchor metric.

Lesson 2 • CAC in Fundraising and Investor Narratives

Investors use CAC to assess capital efficiency and scalability. Students construct compelling, defensible CAC narratives for pitch decks and due diligence.

Lesson 3 • Future-Proofing CAC Strategy

Channel saturation, privacy shifts, and market changes erode CAC efficiency over time. Students build adaptive strategies that sustain CAC performance long-term.

Lesson 4 • Organisational Alignment Around CAC

CAC improvement requires coordination across marketing, sales, and product. Students design cross-functional processes that embed CAC accountability company-wide.
