Step by step

  1. 1

    Capture Steam review volume as the primary demand signal

    11,439 reviews and a 92% 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 Monster Sanctuary, 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 30.0%. That turns an estimated $5,954,228 in gross revenue into roughly $4,167,960 retained by the developer.

Revenue estimates for Monster Sanctuary 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.

  • $10M to $50M: 25% to Steam, 75% to developer

How accurate are these revenue estimates for Monster Sanctuary?

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 ($4,253,020 to $12,759,061) to reflect this uncertainty. For the best estimate we combine the Boxleiter range with a calibrated midpoint (x28) and a calibrated ASP of $19.
