Alliance pack group-buy: contribution after store fees

Illustrative worksheet: alliance/group pack revenue after Google Play service-fee and billing-fee inputs. Fee fractions are reader inputs dated to Play Console Help.
Alliance or guild “group-buy” packs look efficient in gross ROAS until store service fees, billing fees and refunds are applied. This sheet keeps fee fractions as illustrative reader inputs, not as invented industry averages.
Fee definition
Google Play service fees (opened 20 September 2026) state that for transactions with users in the EEA, UK or US starting 30 June 2026, the applicable service fee depends on whether the install is new or existing, and that a 5% billing fee applies when the user completes an in-app digital purchase using Google Play Billing. Standard and programme tiers are tabulated on that page. Understanding Google Play’s lower service fees defines new versus existing installs against the regional rollout date.
This sheet does not quote a single universal commission. Enter the fee fractions that match your programme and region.
Synthetic worked example
| Input | Value | Notes |
|---|---|---|
| Group pack gross (player-paid) | 10,000 | Synthetic |
| Service-fee fraction | 0.20 | Reader input (example only) |
| Billing-fee fraction | 0.05 | Reader input aligned to Play Billing note |
| Estimated refund fraction | 0.03 | Reader input; not a benchmark |
| UA spend attributed to pack buyers | 4,500 | Synthetic |
Contribution after fees and refunds ≈ gross × (1 − service − billing) × (1 − refund) − spend = 10000 × 0.75 × 0.97 − 4500 = 2775.
| Output | Worked-example result |
|---|---|
| After service + billing | 7500.0000 |
| After refund haircut | 7275.0000 |
| Contribution after spend | 2775.0000 |
| Gross ROAS (gross/spend) | 2.2222 |
