Step by step

  1. 1

    Capture Steam review volume as the primary demand signal

    14,482 reviews and a 54% 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 Kingdom Heroes 8, we use a midpoint multiplier of ×36 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 $30, we estimate a realized average sale price of $20 to account for discounting over time.

  4. 4

    Translate gross revenue into developer revenue

    We then apply Steam's effective fee rate of 29.9%. That turns an estimated $10,317,556 in gross revenue into roughly $7,238,167 retained by the developer.

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 x36 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 Kingdom Heroes 8?

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 ($5,731,976 to $17,195,927) to reflect this uncertainty. For the best estimate we combine the Boxleiter range with a calibrated midpoint (x36) and a calibrated ASP of $20.

What would Kingdom Heroes 8 earn on Epic Games Store instead?
