Key takeaways
- A target CPA is a payback decision, not a platform default.
- Month-three LTV after bonus is the number that can actually repay media.
- A cohort of 1,000 FTDs makes the leak visible in euros, not in opinions.
- If D30 value cannot cover CPA, the square shrinks even if FTD volume looks healthy.
- CRM and media must share the same LTV definition or the target is theatre.
Why does day-one CPA lie?
First-time deposits include people who came for the welcome and people who will still be in the wallet in week four. If you set CPA to 80% of day-one NGR, you have priced media as if the bonus did not exist and as if nobody churned. In iGaming both of those assumptions fail.
The honest input is depositing LTV to a horizon the finance team will actually wait for — often D30 or D90 — net of bonus cost and payment failure. Anything wider is a story. Anything narrower is a coupon.
What is the payback equation?
Target CPA ≤ (LTV at horizon − variable fulfilment you will not recover) × risk factor. The risk factor is not a vibe. It is the share of cohorts that historically missed the horizon. If half your geos miss D30, you do not get to use 100% of forecast LTV as the cap.
| Input | Worked value | Note |
|---|---|---|
| D30 depositing LTV | €72 | After bonus, after payment failure |
| Unrecoverable fulfilment | €6 | KYC ops, payment fees not in NGR |
| Hit rate of D30 target | 70% | Share of geos that actually land here |
| Implied cap | (72 − 6) × 0.70 = €46 | This is the target CPA, not €72 |
If media is currently at €61 FTD CPA, the square is €15 too expensive even though a slide might call €72 LTV a comfortable cover. Comfort is not payback.
Worked cohort: 1,000 FTDs
Take 1,000 first-time depositing players bought at €55 CPA. Media cost is €55,000. Bonus cost averages €18 per FTD. D7 depositing rate is 38%. D30 depositing LTV on the whole cohort — including the 62% who never fund again — is €41.
| Line | Per FTD | On 1,000 |
|---|---|---|
| Media | €55 | €55,000 |
| Bonus | €18 | €18,000 |
| D30 NGR | €41 | €41,000 |
| Gap at D30 | −€32 | −€32,000 |
Month three does not rescue this if the missing €32 has to come from the thin tail of slots grind. Either CPA falls, bonus falls, or D30 LTV rises through product and CRM. Celebrating the 1,000 FTDs is how the hole gets a name: growth.
Now rerun at €40 CPA and €12 bonus with the same D30 LTV of €41. Gap is €11 positive before fulfilment. That is a square that can grow. The players did not become nicer. The allocation did.
How often should the target move?
When the horizon data says so, not when a platform auction says so. A weekly CPA that chases CPMs will spend the D30 surplus before D30 arrives. MOTIV locks a target for a market for 30 days, then rebases on the cohort that just closed, which is why paid acquisition and retention CRM have to sit on one grid.
