Step by step

  1. 1

    Capture Steam review volume as the primary demand signal

    30,157 reviews and a 96% 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 The Coffin of Andy and Leyley, we use a midpoint multiplier of ×30 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 $12, we estimate a realized average sale price of $9 to account for discounting over time.

  4. 4

    Translate gross revenue into developer revenue

    We then apply Steam's effective fee rate of 30.0%. That turns an estimated $8,024,778 in gross revenue into roughly $5,617,344 retained by the developer.

How accurate are these revenue estimates for The Coffin of Andy and Leyley?

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 ($5,349,852 to $16,049,555) to reflect this uncertainty. For the best estimate we combine the Boxleiter range with a calibrated midpoint (x30) and a calibrated ASP of $9.
