Step by step

  1. 1

    Capture Steam review volume as the primary demand signal

    23,488 reviews and a 84% 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 UBOAT, we use a midpoint multiplier of ×26 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 $8, we estimate a realized average sale price of $28 to account for discounting over time.

  4. 4

    Translate gross revenue into developer revenue

    We then apply Steam's effective fee rate of 27.9%. That turns an estimated $17,032,088 in gross revenue into roughly $12,274,066 retained by the developer.

Revenue estimates for UBOAT use the Boxleiter method with a broad range from x20 to x60. For the best estimate we use a calibrated midpoint of x26 and a calibrated average sale price of $28 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 UBOAT earned on Steam?

Based on our analysis using the Boxleiter method, we estimate UBOAT's total gross revenue on Steam at approximately $17,032,088.

This estimate comes with a confidence range:

  • Conservative estimate (x20): $13,101,606
  • Calibrated midpoint (x26): $17,032,088
  • Optimistic estimate (x60): $39,304,819

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

How many copies has UBOAT sold on Steam?

With 23,488 Steam reviews and a 84% positive rating, we estimate UBOAT has sold between 469,760 and 1,409,280 copies, with a best estimate of 610,688.

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 x26 that adjusts for the title's age, price tier, genre, and review profile.

How much does Deep Water Studio earn from UBOAT?

After Steam's tiered platform fee of effectively 27.9%, Deep Water Studio keeps an estimated $12,274,066 from UBOAT's gross revenue of $17,032,088.

Here's the breakdown:

  • Gross Revenue: $17,032,088
  • Steam's Fee (27.9%): -$4,758,022
  • Developer Revenue: $12,274,066

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

What percentage does Steam take from UBOAT?

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 UBOAT, with an estimated gross revenue of $17,032,088, this results in an effective rate of 27.9%. Steam keeps approximately $4,758,022 and Deep Water Studio receives $12,274,066.

How accurate are these revenue estimates for UBOAT?

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 ($13,101,606 to $39,304,819) to reflect this uncertainty. For the best estimate we combine the Boxleiter range with a calibrated midpoint (x26) and a calibrated ASP of $28.

What would UBOAT earn on Epic Games Store instead?

If UBOAT generated the same gross revenue on the Epic Games Store, Deep Water Studio would keep approximately $15,108,238 - that's $2,834,171 more than on Steam.

At this revenue level, Epic's concrete platform fee would be $1,923,851. 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 $11,922,462.

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

How long do players spend in UBOAT?

According to SteamSpy data, players spend an average of 31.9 hours in UBOAT, with a median playtime of 11.1 hours. The large gap between average and median suggests a dedicated core community playing well beyond the typical player.
