Step by step

  1. 1

    Capture Steam review volume as the primary demand signal

    23,263 reviews and a 75% 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 Thief, we use a midpoint multiplier of ×28 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 $20, we estimate a realized average sale price of $19 to account for discounting over time.

  4. 4

    Translate gross revenue into developer revenue

    We then apply Steam's effective fee rate of 29.1%. That turns an estimated $12,108,857 in gross revenue into roughly $8,581,643 retained by the developer.

Revenue estimates for Thief use the Boxleiter method with a broad range from x20 to x60. For the best estimate we use a calibrated midpoint of x28 and a calibrated average sale price of $19 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 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 x28 that adjusts for the title's age, price tier, genre, and review profile.

  • 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

How accurate are these revenue estimates for Thief?

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 ($8,649,183 to $25,947,550) to reflect this uncertainty. For the best estimate we combine the Boxleiter range with a calibrated midpoint (x28) and a calibrated ASP of $19.

What would Thief earn on Epic Games Store instead?

If Thief generated the same gross revenue on the Epic Games Store, Eidos-Montréal, Feral Interactive (Mac) would keep approximately $10,775,794 - that's $2,194,151 more than on Steam.

At this revenue level, Epic's concrete platform fee would be $1,333,063. 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 $8,476,200.

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