Method
How to calculate LTV
This calculator estimates customer lifetime revenue by multiplying average purchase value by purchases per year and average customer lifespan.
Formula
Estimated customer lifetime value = Average purchase value × Purchases per year × Customer lifespan
Assumptions
- This is a simple lifespan-based revenue LTV model, not a profit or churn-rate model.
- Average purchase value, frequency, and lifespan remain representative over the relationship.
- Purchase frequency is annual and customer lifespan is measured in years.
Multiplication retains full numeric precision. Currency displays two decimals.
How to interpret the result
This calculator estimates customer lifetime revenue. It does not automatically subtract product costs, acquisition costs, servicing costs, overhead, or other business expenses. It must not be interpreted as lifetime profit.
What this customer LTV estimate includes
The calculator first estimates annual customer revenue from average purchase value and purchase frequency. It then multiplies that amount by customer lifespan to estimate lifetime revenue.
Use averages from the same customer cohort whenever possible. Mixing order value from high-value customers with lifespan from the whole customer base can produce an estimate that does not represent either group.
How to use LTV in acquisition decisions
Compare revenue LTV with CAC carefully: revenue does not equal profit and still needs to cover product, servicing, overhead, and acquisition costs. Also consider payback timing because equal lifetime revenue can arrive at very different speeds.
Recalculate LTV when pricing, purchase frequency, margin, or retention changes. Scenario analysis is more informative than treating one estimate as a permanent customer value.
Customer value measures compared
This calculator reports revenue-based customer value and keeps it distinct from profit-based measures.
| Measure | Formula | What it shows |
|---|---|---|
| Annual revenue | Average order value × Purchases per year | Expected customer revenue during one year. |
| Lifetime purchases | Purchases per year × Customer lifespan | Estimated number of purchases over the relationship. |
| Estimated LTV | Annual revenue × Customer lifespan | Estimated lifetime revenue before business costs. |
