Estimate sales and net revenue from a Steam review count -- shows all the math, no black box
Steam sales tend to run roughly 20-60x the review count. Lower multipliers fit games with high review propensity (competitive, community-driven genres, higher-priced titles); higher multipliers fit casual/regional-heavy audiences where a smaller share of buyers leave a review.

The Boxleiter method is a widely used indie-dev heuristic for estimating a game's unit sales from its public Steam review count, named after the analyst who popularized the approach in community discussions of Steam sales data. The core idea is simple: only a fraction of buyers ever leave a review, so if you know roughly what that fraction is, you can work backward from review count to an estimated number of sales by multiplying by a factor -- commonly cited in the 20-60x range, with 30-50x being typical for most titles.
That multiplier isn't fixed because review propensity itself varies a lot: genre (competitive and community-driven games tend to get reviewed more), price point (buyers of pricier games are statistically more likely to leave a review), region (review rates differ across markets), and how wishlists convert to actual reviews after purchase. Because of that spread, the method produces a rough order-of-magnitude estimate, not a precise sales figure -- treat any single number it produces as the center of a wide range, not a fact.
Since October 1, 2018, Valve applies a tiered revenue share to Steam sales, calculated per game (not account-wide across a publisher's whole catalog). The split is marginal, meaning each rate only applies to the slice of revenue that falls inside that tier -- not the whole amount at the top tier's rate.
| Gross revenue band | Steam's cut | Developer's cut |
|---|---|---|
| $0 -- $10,000,000 | 30% | 70% |
| $10,000,000 -- $50,000,000 | 25% | 75% |
| Above $50,000,000 | 20% | 80% |
For example, a game with $12 million in gross revenue pays 30% on the first $10 million ($3,000,000) plus 25% on the remaining $2 million ($500,000), for a total Steam cut of $3,500,000 -- not 25% applied to the full $12 million.
Review-count-based sales estimates are useful for a ballpark figure, but they have real limitations worth keeping in mind:
A community-derived rule of thumb for estimating a Steam game's unit sales from its public review count, by multiplying reviews by a factor typically between 20 and 60.
It's a rough estimate with wide error bars, not a precise figure. Review rates differ enormously by genre, marketing, price, region, and sales channel. Treat the output as an order-of-magnitude range.
Since October 1, 2018, Steam uses a tiered, per-game revenue share: 30% on the first $10 million of gross revenue, 25% on the next $10-50 million, and 20% above $50 million, applied marginally.
Yes -- refund rate (default 8%), regional pricing discount (default 15%), and VAT/sales tax (default 10%) are all visible, editable inputs rather than hidden constants.
Most Steam analytics sites hand you a single black-box number. This calculator exposes every step -- units sold, gross revenue, Steam's tiered cut, refunds, regional discount, and tax -- so you can see exactly which assumption is driving the result and adjust it yourself.
