How to Read Your Results
Annual contribution shows what remains each year after direct costs of serving the customer.
Expected lifetime is a retention-based average, not a guaranteed number of years for every customer.
Gross CLV is calculated before acquisition cost is deducted.
Net CLV is the estimated lifetime contribution remaining after acquisition cost.
LTV to CAC uses gross CLV, so it should be read alongside net CLV and acquisition payback timing.
Assumptions & Important Notes
- Revenue, direct costs, and retention are held constant within each example.
- The model estimates expected lifetime as one divided by annual churn.
- Examples exclude discounting, taxes, and shared overhead allocation.
- Amounts are illustrative and are not benchmarks or business advice.

Frequently Asked Questions
Can I use monthly customer data in this annual CLV calculator?
Convert monthly values to consistent annual amounts and use an annual retention rate, or use a model designed for monthly inputs.
Why does the example use gross CLV for the LTV to CAC ratio?
The calculator defines the ratio as gross lifetime value divided by acquisition cost, while net CLV separately deducts CAC.
Can net customer lifetime value be negative?
Yes. Net CLV can be negative if gross lifetime contribution is less than acquisition cost.
Should direct costs include general company overhead?
The model is intended for costs directly associated with serving customers. Shared overhead may be reviewed separately unless it can be allocated consistently.
