What this calculator measures
This simple CLV model estimates lifetime revenue from purchase size, yearly frequency, and customer lifespan.
Formula
CLV = Average Purchase Value x Purchases per Year x Lifespan in Years
Worked example
- 1A customer spends $75 four times yearly for three years.
- 2$75 x 4 x 3 = $900 estimated lifetime revenue.
How to interpret the result
Use cohort data where possible. Revenue CLV is not profit and does not discount future cash flows.
Common mistakes and limits
- Using optimistic lifespan, mixing customer segments, or comparing revenue CLV directly with fully loaded CAC.
Frequently asked questions
Does this include margin?
No. It estimates revenue, not contribution or profit.
What lifespan should I use?

Is this predictive?
It is a planning estimate based on the assumptions entered.
