This is based on the Boxleiter method, which uses the observation that roughly 1 in every 20 to 60 buyers leaves a Steam review. For the midpoint we do not assume a universal 30x value; we use a calibrated multiplier of x26 that adjusts for the title's age, price tier, genre, and review profile.

After Steam's tiered platform fee of effectively 24.3%, Unknown Worlds Entertainment keeps an estimated $52,470,468 from Subnautica: Below Zero's gross revenue of $69,338,084.

Steam uses a tiered revenue sharing model that reduces the platform's cut as a game earns more:

• First $10 million: 30% to Steam, 70% to developer
• $10M to $50M: 25% to Steam, 75% to developer
• Above $50M: 20% to Steam, 80% to developer

For Subnautica: Below Zero, with an estimated gross revenue of $69,338,084, this results in an effective rate of 24.3%. Steam keeps approximately $16,867,617 and Unknown Worlds Entertainment receives $52,470,468.

These estimates use the Boxleiter method, a widely-used industry approach that estimates game sales from the number of Steam reviews.

Factors that affect accuracy:

• Review-to-purchase ratio varies by genre
• Discount history - games with frequent deep sales may have higher ratios
• Regional pricing - different prices in different markets are not captured
• Refunds - Steam's return policy means some counted sales were refunded
• Bundled sales - keys sold through third-party bundles may not generate reviews

We provide a confidence range ($53,336,988 to $160,010,964) to reflect this uncertainty. For the best estimate we combine the Boxleiter range with a calibrated midpoint (x26) and a calibrated ASP of $28.

If Subnautica: Below Zero generated the same gross revenue on the Epic Games Store, Unknown Worlds Entertainment would keep approximately $61,137,514 - that's $8,667,047 more than on Steam.

At this revenue level, Epic's concrete platform fee would be $8,200,570. 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 $48,536,659.

Note: This is a hypothetical comparison. Actual sales volumes differ significantly between platforms, and Steam's larger user base typically drives substantially higher sales.
