Will a Roblox sponsored ad campaign pay back in 7 days? Models D1/D7 retention decay and ARPDAU.

VERIFIED DIRECT ANSWERFacts verified: 2026-10-23Primary Roblox Docs ↗

A Roblox ad campaign breaks even within 7 days when 7-day creator LTV (Active Days × ARPDAU × 70% creator share) is greater than or equal to your Cost Per Acquisition (CPI in Robux). With 30% D1 and 8% D7 retention (~1.85 active days in week 1), you need ~7.8 R$ gross ARPDAU to pay back a 10 R$ CPI at a 70% creator share.

METHOD.01

Formula & Engineering Methodology

Retention between day 1 and day 7 is drawn as a smooth curve through your two numbers (a power-law decay). It is a model, not your real curve.
Active days = 1 for the install day + the curve summed over days 1–6.
Earned per player = active days × spend per day × creator share.
The ad pays back when earned per player ≥ ad cost per player. Real results vary with game, country and time of year.

Q.01

How is 7-day player LTV estimated from D1 and D7 retention?

We fit a power-law retention curve R(t) = D1 × t^b between Day 1 and Day 7, sum the active probability from Day 0 (install day = 1.0) through Day 6, and multiply by daily spend (ARPDAU) and your 70% creator share.

Q.02

Should I run sponsored ads if my D1 retention is below 20%?

Usually only small test budgets to measure onboarding. Fixing first-5-minute tutorial drop-offs and UI shop conversion increases LTV across every future player before you scale ad spend.
