Best for

Operators who need a practical diagnostic view of unit economics before they decide what to fix first.

Decision

Which lever to fix first when unit economics slip: acquisition cost, retention, pricing, margin, or cash timing.

Use it when

You have the headline ratios already, but you need a clear next action for the review meeting.

What the dashboard is for

The dashboard is not meant to replace the underlying metric pages. It is meant to tell you which lever is probably wrong when the headline stack looks weak or contradictory. Use it when you already know the definitions and need a decision path.

Five failure zones

  • Acquisition cost is too high: CAC or blended CAC is the first problem.
  • Retention is too weak: churn or customer lifetime is pulling LTV down.
  • Pricing or monetization is too low: ARPA is not supporting the model.
  • Gross margin is too thin: the business cannot recover spend quickly enough.
  • Cash timing is too slow: payback is too long even if the ratio stack looks fine.

How to diagnose the bottleneck

  • If CAC is high and ARR growth is weak, start with acquisition efficiency.
  • If LTV looks fine on paper but payback is long, check gross margin and cash timing next.
  • If LTV is weak, inspect churn, customer lifetime, and cohort behavior before changing spend.
  • If the dashboard looks healthy in aggregate but bad by segment, stop trusting blended averages.

What to open next

  • Open CAC if the main issue is acquisition cost.
  • Open LTV if the main issue is retention, lifetime, or churn assumptions.
  • Open CAC payback if the main issue is cash recovery speed.
  • Open ARR if the main issue is recurring scale or growth quality.
  • Open the unit economics hub if you need the top-level map first.

FAQ

Is LTV:CAC of 3* always good-
Not always. If payback is long, you can still run out of cash. For fast-growing businesses, payback and cash constraints often matter more than a single ratio.
Should I use logo churn or revenue churn in LTV-
For accuracy, use cohort-based revenue retention curves (especially if expansion is meaningful). Logo churn is a shortcut that can mislead when revenue per account changes over time.
Which lever should I fix first-
Fix the first constraint you find. If acquisition cost is too high, work CAC. If retention is weak, work churn and customer lifetime. If LTV looks acceptable but cash is still tight, work payback and gross margin.
