Starting values are editable examples.

Observed revenue LTV (6 months)
$12.00
Observed contribution LTV
$9.00

Observed through the entered window, not a full-lifetime forecast. The denominator includes users who have already left.

How it works

Observed revenue LTV = accumulated revenue ÷ original base. Contribution LTV = (revenue − costs) ÷ original base.

Worked example

1,000 users, 12,000 revenue and 3,000 costs over six months give observed revenue LTV of 12 and contribution of 9.

Assumptions and limits

Observed through the entered window, not a full-lifetime forecast. The denominator includes users who have already left.

Frequently asked questions

How do I use the cohort ltv calculator?

Calculate accumulated revenue and contribution per original cohort user over a finite observed window.

Can I divide only by customers still active?

That excludes departed customers and inflates the cohort reading. Keep the original base to compare windows.

Do I need an account and are my inputs uploaded?

No account is required. Calculations run in your browser. Entered numbers and text are not included in tool analytics events; only the tool ID, language, and action are recorded.
