# CAC payback optimization

> Optimize acquisition against retained value and payback.

FloKit connects campaign spend to subscription outcomes so teams can optimize for payback instead of install volume alone.

## Inputs

* Channel spend, campaign metadata, bids, budgets, and targeting
* Creative IDs, variants, hooks, formats, and fatigue signals
* Attribution and landing context
* Activation, paywall, subscription, renewal, cancellation, and refund events
* Revenue and LTV models

## Outputs

* Cohort quality comparisons
* CAC, ROAS, payback, and projected LTV views
* Recommended budget and creative moves
* Explanations for why a growth action is recommended

<Info>
  Exact metric definitions should match your finance and growth operating model before FloKit actions are allowed to execute automatically.
