Customer Acquisition Cost vs. Lifetime Value
Reviewed by the Savora Finance Editorial Team · Last reviewed 2026-07-31
Compare customer acquisition cost with expected customer value to evaluate marketing economics and growth efficiency.
What this decision involves
Customer acquisition cost measures spending required to gain a customer, while lifetime value estimates the gross economic contribution expected over the relationship. Both metrics depend heavily on consistent definitions.
Factors to compare
- Included sales and marketing costs
- Gross margin versus revenue
- Retention assumptions
- Payback period
- Channel-specific performance
Practical example
A campaign can appear profitable on revenue while remaining unattractive after product costs, service costs, and customer churn are included.
Five-factor decision test
- Cost: include fees, taxes, and opportunity cost.
- Time: use the same comparison period.
- Liquidity: measure access to cash after the decision.
- Risk: test an unfavorable scenario.
- Flexibility: review penalties and reversibility.
Common mistakes
- Using headline numbers without reading the terms
- Ignoring taxes, fees, or timing
- Comparing options across different periods
- Failing to preserve emergency liquidity
