How to use the Customer Lifetime Value Calculator.
Lifetime value estimates are sensitive to retention assumptions. Label simple models as estimates and keep revenue lifetime value separate from contribution or gross profit lifetime value.
Make the workflow fit your task.
Choose whether the estimate concerns revenue or gross profit and define the customer lifetime assumption. Show the simple model and its inputs, then explore how retention or margin changes affect the result. Keep estimates distinct from realized cohort outcomes.
- What you provide
- Revenue, margin, retention and chosen model.

Illustrative input and output · a teaching example, not a live WebAct run
Example input
Illustrative model: USD 40 monthly revenue per customer, 75% gross margin and a 10-month expected paid lifetime.
Completed example
Revenue LTV: USD 400. Gross profit LTV: USD 300 before acquisition and other excluded costs. This estimate assumes the supplied lifetime and margin remain representative.

Decisions and troubleshooting.
Can a simple lifetime-value estimate be treated as guaranteed future revenue?
No. It depends on assumptions about retention, spending and margins that may change.
Why do two LTV reports disagree despite using the same customers?
They may use revenue versus gross profit, different lifetime models or discounting assumptions. Compare definitions before comparing values.
