Step by step

  1. 1

    Capture Steam review volume as the primary demand signal

    6,001 reviews and a 97% 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 Opus Magnum, we use a midpoint multiplier of ×27 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 $3,012,082 in gross revenue into roughly $2,108,457 retained by the developer.

Revenue estimates for Opus Magnum use the Boxleiter method with a broad range from x20 to x60. For the best estimate we use a calibrated midpoint of x27 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.

Frequently Asked Questions

How much has Opus Magnum earned on Steam?

This estimate comes with a confidence range:

  • Conservative estimate (x20): $2,231,172
  • Calibrated midpoint (x27): $3,012,082
  • Optimistic estimate (x60): $6,693,515

The actual revenue may vary due to regional pricing, seasonal discounts, and refund rates.

With 6,001 Steam reviews and a 97% positive rating, we estimate Opus Magnum has sold between 120,020 and 360,060 copies, with a best estimate of 162,027.

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 x27 that adjusts for the title's age, price tier, genre, and review profile.

How much does Zachtronics earn from Opus Magnum?

After Steam's tiered platform fee of effectively 30.0%, Zachtronics keeps an estimated $2,108,457 from Opus Magnum's gross revenue of $3,012,082.

Here's the breakdown:

  • Gross Revenue: $3,012,082

What percentage does Steam take from Opus Magnum?

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 Opus Magnum, with an estimated gross revenue of $3,012,082, this results in an effective rate of 30.0%. Steam keeps approximately $903,625 and Zachtronics receives $2,108,457.

How accurate are these revenue estimates for Opus Magnum?

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 ($2,231,172 to $6,693,515) to reflect this uncertainty. For the best estimate we combine the Boxleiter range with a calibrated midpoint (x27) and a calibrated ASP of $19.

What would Opus Magnum earn on Epic Games Store instead?

If Opus Magnum generated the same gross revenue on the Epic Games Store, Zachtronics would keep approximately $2,770,632 - that's $662,175 more than on Steam.

At this revenue level, Epic's concrete platform fee would be $241,450. 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 $2,108,457.

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