How accurate is the Steam revenue calculator?

The calculator uses the Boxleiter method, an industry-standard approach that estimates units sold based on review count multiplied by a genre-adjusted factor (typically 30-50x for indie games). Accuracy varies by game but is generally within 30-50% of actual revenue. Games with more reviews tend to produce more accurate estimates.

What is the Boxleiter method?

The Boxleiter method estimates Steam game sales by multiplying the number of user reviews by a multiplier (typically 20-80x depending on genre and game type). It was developed by game industry analyst Simon Carless and refined by Jake Birkett. The multiplier accounts for the fact that only a small percentage of buyers leave reviews.

How much does Steam take from game sales?

Steam takes a 30% revenue share on the first $10 million in sales, 25% on sales between $10-50 million, and 20% on sales above $50 million. Most indie games fall in the 30% tier. After Steam's cut, developers also face regional pricing adjustments averaging about 22% discount globally.

Does the review-to-sales multiplier vary by genre?

Yes, significantly. Action and FPS games tend to have higher multipliers (50-80x) because their audiences review less frequently. Indie and narrative games have lower multipliers (20-40x) as their audiences are more likely to leave reviews. The calculator automatically adjusts the multiplier based on the game's primary genre.

How do I estimate Steam game sales?

The most common method is the Boxleiter method: multiply a game's Steam review count by a genre-specific multiplier (typically 20-60x), then multiply by the game's price. For example, a $14.99 game with 500 reviews has likely sold 12,500-30,000 copies. Our free Steam revenue calculator automates this with genre-adjusted multipliers for more accurate results.

How much money does the average Steam game make?

The median Steam game earns between $5,000 and $15,000 in lifetime gross revenue. However, the distribution is heavily skewed: the top 10% earn over $200,000, while the bottom 50% earn under $5,000. Well-made indie games with solid marketing typically fall in the $50,000-$300,000 range depending on genre.

How much has Terraria made on Steam?

An estimated 46,866,350 copies sold, $468.2M gross and about $292.2M net to the developer, derived from 1,233,325 Steam reviews using the Boxleiter method. Valve publishes no per-game sales figures, so this is a calculated estimate and not reported sales -- the plausible net range runs $215.3M to $422.9M.

Estimated units: 46,866,350
Estimated gross: $468.2M
Estimated net to developer: $292.2M
Steam reviews: 1,233,325
List price: $9.99

How this estimate was calculated

The Boxleiter method multiplies a game's public Steam review count by a genre-adjusted figure to approximate units sold. Terraria carries 1,233,325 reviews and reads as platformer, so the calculator applies a 28x to 55x range with 38x as the midpoint. Gross is those units at the current list price. The net figure then applies Valve's tiered revenue share (30% up to $10M lifetime gross, 25% to $50M, 20% above it) and a 0.78 factor for regional pricing, which is why net lands well below gross. Net here is still before tax, refunds and chargebacks, so a developer's banked total is lower again.

What makes this estimate high confidence

Large review sample (1000+)
Established title with stable sales pattern

Review-count estimation is a rough instrument: review rates vary by genre, price, audience and how hard a game prompts for reviews, and the method cannot see bundles, key sales, refunds or regional price differences at all. Treat the range as the answer and the midpoint as a convenience. Against other games in its genre, this estimate lands around the 100th percentile.
