Step by step

  1. 1

    Capture Steam review volume as the primary demand signal

    23,847 reviews and a 79% positive rating are used as the starting point because Steam review counts correlate strongly with paid ownership.

  2. 2

    Apply a calibrated Boxleiter multiplier

    For X4: Foundations, we use a midpoint multiplier of ×25 and show a wider range from ×20 to ×60 to reflect uncertainty.

  3. 3

    Use a realistic realized sale price instead of only list price

    Rather than relying only on the current price of $50, we estimate a realized average sale price of $47 to account for discounting over time.

  4. 4

    Translate gross revenue into developer revenue

    We then apply Steam's effective fee rate of 26.8%. That turns an estimated $28,312,351 in gross revenue into roughly $20,734,263 retained by the developer.

For the best estimate we use a calibrated midpoint of x25 and a calibrated average sale price of $47 instead of a flat 30x/0.75 model. Factors like age, price tier, discount history, genre, and review profile all affect the true reviews-to-sales ratio.

This estimate comes with a confidence range:

  • Conservative estimate (x20): $22,649,881
  • Calibrated midpoint (x25): $28,312,351
  • Optimistic estimate (x60): $67,949,642

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 x25 that adjusts for the title's age, price tier, genre, and review profile.

After Steam's tiered platform fee of effectively 26.8%, Egosoft keeps an estimated $20,734,263 from X4: Foundations's gross revenue of $28,312,351.

Here's the breakdown:

  • Gross Revenue: $28,312,351

  • Developer Revenue: $20,734,263

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

What percentage does Steam take from X4: Foundations?

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 X4: Foundations, with an estimated gross revenue of $28,312,351, this results in an effective rate of 26.8%. Steam keeps approximately $7,578,088 and Egosoft receives $20,734,263.

How accurate are these revenue estimates for X4: Foundations?

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 ($22,649,881 to $67,949,642) to reflect this uncertainty. For the best estimate we combine the Boxleiter range with a calibrated midpoint (x25) and a calibrated ASP of $47.

What would X4: Foundations earn on Epic Games Store instead?

If X4: Foundations generated the same gross revenue on the Epic Games Store, Egosoft would keep approximately $25,034,869 - that's $4,300,606 more than on Steam.

At this revenue level, Epic's concrete platform fee would be $3,277,482. 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 $19,818,646.

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