INSIDE Steam Revenue & Sales Estimates

Based on our analysis using the Boxleiter method, we estimate INSIDE's total gross revenue on Steam at approximately $39,109,439.

This estimate comes with a confidence range:

• Conservative estimate (x20): $31,287,551
• Calibrated midpoint (x25): $39,109,439
• Optimistic estimate (x60): $93,862,652

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

With 68,046 Steam reviews and a 97% positive rating, we estimate INSIDE has sold between 1,360,920 and 4,082,760 copies, with a best estimate of 1,701,150.

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 x25 that adjusts for the title's age, price tier, genre, and review profile.

After Steam's tiered platform fee of effectively 26.3%, Playdead keeps an estimated $28,832,079 from INSIDE's gross revenue of $39,109,439.

Here's the breakdown:

• Gross Revenue: $39,109,439
• Steam's Fee (26.3%): -$10,277,360
• Developer Revenue: $28,832,079

Note: This doesn't account for publisher shares, taxes, or development costs.

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 INSIDE, with an estimated gross revenue of $39,109,439, this results in an effective rate of 26.3%. Steam keeps approximately $10,277,360 and Playdead receives $28,832,079.

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 ($31,287,551 to $93,862,652) to reflect this uncertainty. For the best estimate we combine the Boxleiter range with a calibrated midpoint (x25) and a calibrated ASP of $23.

If INSIDE generated the same gross revenue on the Epic Games Store, Playdead would keep approximately $34,536,306 - that's $5,704,227 more than on Steam.

At this revenue level, Epic's concrete platform fee would be $4,573,133. 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 $27,376,607.

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

According to SteamSpy data, players spend an average of 6 hours in INSIDE, with a median playtime of 3.9 hours. This indicates solid player engagement.
