Accounting Customer Lifetime Value Calculator Examples
Worked per-customer lifetime value scenarios showing how revenue, costs, churn, and acquisition cost affect estimated net CLV.
These examples use the calculator's steady-state method: monthly contribution is multiplied by estimated lifetime, then customer acquisition cost is deducted. They illustrate different unit-economics profiles rather than forecasts of actual performance.
Example 1: Subscription customer with moderate churn
A software subscription earns $200 per month, has $60 of direct cost and $20 of servicing cost, and costs $300 to acquire.

Estimated gross CLV is $2,400 and estimated net CLV is $2,100 per customer.
Example 2: Higher churn and a higher acquisition cost

Estimated net CLV is $250 per customer after a $500 acquisition cost.
Example 3: Low monthly contribution and negative net value
A service earns $100 monthly, has $45 of direct cost and $35 of servicing cost, 8% monthly churn, and a $350 acquisition cost.

Example 4: Lower churn for a higher-value account
A managed-service customer earns $500 monthly, has $140 of direct cost and $60 of servicing cost, 2% monthly churn, and a $1,000 acquisition cost.

How to Read Your Results
Net customer lifetime value is the estimated per-customer contribution after direct costs, servicing costs, and acquisition cost.
Gross customer lifetime value excludes acquisition cost, making it useful for separating retention economics from acquisition spending.
Expected lifetime is an average estimate based on the stated monthly churn rate, not a guaranteed duration.
A negative net result means the supplied assumptions do not produce enough lifetime contribution to cover acquisition cost.
Compare results between comparable customer segments, periods, and cost-allocation methods.
Assumptions & Important Notes
- Each example uses a constant monthly churn rate and stable monthly revenue and costs.
- Acquisition cost is charged once to each acquired customer.
- The calculation is undiscounted and does not account for the timing of monthly cash flows.
- Examples exclude shared overhead, taxes, financing costs, and other costs not entered as customer-specific amounts.

Frequently Asked Questions
Why does a small churn change affect the examples so much?
Expected lifetime is calculated as the inverse of churn. Lower monthly churn therefore extends the estimated contribution period in this model.
Why is acquisition cost deducted only once?
The calculator treats acquisition cost as the one-time cost assigned to bringing in one customer, rather than a recurring monthly cost.
Can I use these examples for different customer segments?
Yes, if revenue, direct costs, servicing costs, churn, and acquisition cost are measured consistently for each segment.
Do the examples include overhead costs?
No. Include an allocated amount in monthly servicing cost only if it is appropriate for the analysis and consistently applied.
