| Stage | USD/month |
|---|---|
| Gross storefront sales | $1.2k |

| After refunds (-9.5% median) | $979 |

## Monthly review counts, oldest to newest (24 months)

8, 12, 6, 8, 4, 3, 3, 6, 10, 3, 4, 11, 8, 57, 20, 4, 7, 16, 10, 9, 3, 7, 4, 12

## Methodology

Units are estimated from Steam-purchase reviews times a release-cohort multiplier (Boxleiter method, 20-75x by year). Revenue uses an effective price (lifetime discounts and regional pricing) and nets out VAT (~13%), refunds (~9.5%) and Steam's 30% cut: roughly 55% of gross reaches the developer.
