BIOMUTANT Steam Revenue & Sales Estimates

Based on our analysis using the Boxleiter method, we estimate BIOMUTANT's total gross revenue on Steam at approximately $17,431,264.

This estimate comes with a confidence range:

• Conservative estimate (x20): $10,564,403
• Calibrated midpoint (x33): $17,431,264
• Optimistic estimate (x60): $31,693,208

The actual revenue may vary due to regional pricing, seasonal discounts, and refund rates.

With 19,427 Steam reviews and a 66% positive rating, we estimate BIOMUTANT has sold between 388,540 and 1,165,620 copies, with a best estimate of 641,091.

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 x33 that adjusts for the title's age, price tier, genre, and review profile.

After Steam's tiered platform fee of effectively 27.9%, Experiment 101 keeps an estimated $12,573,448 from BIOMUTANT's gross revenue of $17,431,264.

Here's the breakdown:

• Gross Revenue: $17,431,264
• Steam's Fee (27.9%): -$4,857,816
• Developer Revenue: $12,573,448

Note: This doesn't account for publisher shares, taxes, or development costs.

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 BIOMUTANT, with an estimated gross revenue of $17,431,264, this results in an effective rate of 27.9%. Steam keeps approximately $4,857,816 and Experiment 101 receives $12,573,448.

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 ($10,564,403 to $31,693,208) to reflect this uncertainty. For the best estimate we combine the Boxleiter range with a calibrated midpoint (x33) and a calibrated ASP of $27.

If BIOMUTANT generated the same gross revenue on the Epic Games Store, Experiment 101 would keep approximately $15,459,513 - that's $2,886,064 more than on Steam.

At this revenue level, Epic's concrete platform fee would be $1,971,752. 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 $12,201,885.

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

According to SteamSpy data, players spend an average of 8.2 hours in BIOMUTANT, with a median playtime of 3.7 hours. The large gap between average and median suggests a dedicated core community playing well beyond the typical player.
