Accounting Customer Lifetime Value Calculator FAQ
Answers to common questions about per-unit customer lifetime value, churn-based lifetime estimates, costs, acquisition cost, and results.
This FAQ explains what the per-unit customer lifetime value calculator measures, how its churn-based method works, and how to interpret its estimated outputs. Results are educational estimates and should be considered alongside relevant business records and accounting policies.
General customer lifetime value questions
Basic definitions and intended uses of the calculator.
What does this customer lifetime value calculator estimate?
It estimates the net contribution from one typical customer after monthly direct costs, monthly servicing costs, and customer acquisition cost.
What does per-unit mean in this calculator?
Per-unit means the calculation is made for one customer rather than for the whole customer base.
Is customer lifetime value the same as lifetime revenue?
No. Lifetime revenue is total estimated revenue. Customer lifetime value in this calculator is contribution after specified costs, with net CLV also deducting acquisition cost.
Can this calculator be used for subscriptions and non-subscription businesses?
It can be used where average monthly revenue, customer-specific costs, and a meaningful monthly churn estimate can be defined.
Formula and churn questions
How the estimated lifetime and value calculations are derived.
How does the calculator convert churn into customer lifetime?
It divides 1 by monthly churn expressed as a decimal. A 4% monthly churn rate, for example, produces an estimated lifetime of 25 months.
What happens when monthly churn is lower?
Lower churn increases the estimated lifetime in the simplified formula, which increases gross lifetime contribution when monthly contribution stays positive.
Why does the calculator use monthly churn rather than annual churn?
The revenue and cost inputs are monthly, so monthly churn keeps the lifetime estimate on the same time basis.
How is monthly contribution calculated?
Monthly contribution equals average monthly revenue minus monthly direct cost and monthly servicing cost.
How is net CLV calculated?
Net CLV equals gross customer lifetime value minus the acquisition cost allocated to one customer.
Costs and inputs
Choosing inputs that match the purpose of the estimate.
What belongs in monthly direct cost?
Include delivery costs that increase when another customer is served, such as product, fulfilment, transaction, hosting, or service-delivery costs where relevant.
What belongs in monthly servicing cost?
Include recurring customer-specific support, account management, onboarding follow-up, fulfilment, or similar servicing costs.
Should acquisition cost include sales and marketing spending?
It can include the sales and marketing cost attributed to acquiring one customer, using a method that is consistent across the comparison.
Should refunds and credits affect monthly revenue?
If they are material and recurring, using a net monthly revenue measure may provide a more representative estimate.
Should shared overhead be included?
This calculator focuses on customer-specific costs. Any allocation of shared overhead depends on the purpose of the analysis and the organisation's approach.
Accuracy and interpretation
How to use the outputs carefully.
Is this customer lifetime value result a forecast?
No. It is a simplified estimate based on the inputs and constant-churn assumption; actual customer behaviour and costs can differ.
Why might actual CLV be different from the calculated result?
Churn, spending, pricing, product mix, support needs, refunds, and cost levels can change over a customer relationship.
Does the calculation discount future cash flows?
No. The result is undiscounted, so it does not reduce future contribution for the time value of money.
What does a negative net customer lifetime value mean?
It means estimated lifetime contribution before acquisition cost is less than the acquisition cost, based on the supplied assumptions.
Can I compare results across customer groups?
Yes, provided each group uses comparable time periods, cost definitions, churn measurement, and acquisition-cost allocation.
What is customer lifetime value on a per-unit basis?
It is an estimate of the total economic contribution of one typical customer over the expected relationship period.
