If F1 Manager 2024 generated the same gross revenue on the Epic Games Store, Frontier Developments would keep approximately $3,997,510 - that's $913,127 more than on Steam.
At this revenue level, Epic's concrete platform fee would be $408,751. Epic charges 0% on the first $1 million in annual per-app revenue and then 12% on the remaining amount. On GOG (30% cut), the developer would earn approximately $3,084,383.
Note: This is a hypothetical comparison. Actual sales volumes differ significantly between platforms, and Steam's larger user base typically drives substantially higher sales.
