UA Payback &
Economics Grader.
Decompose customer acquisition cost (CAC) against cohort LTV. Model organic download multipliers and estimate the exact day your marketing investment breaks even.
Model Parameters
Breakeven Outcomes
The dynamics of marketing payback.
Paid scaling is not a simple transaction—it is a capital float loop. Real marketing velocity is determined by the speed of capital recovery.
Organic K-Factor
The viral booster. If for every 1 paid install, you capture 0.3 organic installs, your effective CAC drops by 23%. Organic loops represent the highest leverage to pull in the breakeven day.
Cash Exposure Window
The net cash deficit. This represents the absolute peak debt of your cohort before payback begins. If your exposure is too high, scaling will deplete your cash reserves before LTV materializes.
Retention Slope
The speed of LTV build-up. Flatter retention curves mean users spend longer in the app, causing LTV to scale continuously. A steep onboarding drop-off delays payback indefinitely.
Year 1 ROI Cap
The compounding capacity. High Year 1 ROI allows you to reinvest your marketing capital 3–4 times per year, generating exponential growth curves that competitors cannot match.
Is your payback window leaking capital?
When user acquisition CAC outpaces Day 180 LTV, scaling is a loss-making machine. We run diagnostic monetization audits and progression analyses to flatten cohort decay loops, elevate baseline ARPU, and integrate referral K-factors to secure payback velocity.
