LTV & Payback Calculator

Project cumulative LTV from a retention curve and ARPDAU, then read off when a CPI pays back — or the most you could pay per install for a given payback deadline.

Observed retention

D1 (%)

D3 (%)

D7 (%)

D30 (%)

Leave a field at 0 to exclude it — at least two values are required to fit a curve. Already used the Retention Calculator? It can send its curve here directly.

ARPDAU ($), net of store fees

Blended IAP + IAA revenue per daily active user. Net this down for store fees yourself first — the ROAS Target Calculator has that math if you need it.

CPI ($) — optional

Shows the day this CPI pays back.

Target payback day — optional

Shows the max CPI you could pay to break even by then.

Day	Cumulative LTV
D1	$0.11
D3	$0.16
D7	$0.23
D14	$0.33
D30	$0.50
D60	$0.74
D90	$0.95
D180	$1.46
D365	$2.27

LTV through day n = expected player-days through day n (1, plus the retention curve summed day by day) times ARPDAU, assumed flat over the cohort's life. Payback day is the first day cumulative LTV reaches the CPI you entered.
