How to Estimate Steam Sales From Review Count
Steam doesn't publish per-game sales figures, but review counts are public — and indie devs have used them for years to ballpark a competitor's or a potential wishlist target's revenue. Here's the method, its limits, and Steam's actual revenue-share math.

The problem
Analytics sites like VG Insights and Gamalytic estimate Steam sales from review counts, but present the result as a single confident-looking number with the math hidden. The underlying method — commonly called the "Boxleiter method" after the analyst who popularized it — is simple: multiply review count by a multiplier, typically somewhere between 20 and 60 depending on genre, price, and region. The wide range is the whole story; a tool that hides it is hiding the actual uncertainty.
How it works
- Enter a game's review count, its price, and a review-to-sales multiplier (defaults to 35, adjustable from 20–60).
- The tool multiplies reviews × multiplier for estimated units sold, then units × price for gross revenue.
- Steam's tiered cut, refunds, regional pricing discount, and VAT are applied step by step, each one visible and each one an editable assumption — not a black box.
Everything runs in your browser — no review count or game name is ever sent anywhere.
When to use this tool
Use it for rough market research — sizing a genre, sanity-checking a competitor's scale, or estimating your own game's revenue mid-launch from its review count. Don't use it for financial planning, investor materials, or anything where the wide error bars of a review-based estimate would matter — it's a ballpark, not an audit.
Tips and reference
Steam's revenue share is tiered, not flat, and it applies per game since October 2018:
| Lifetime gross revenue | Steam's cut |
|---|---|
| $0 – $10,000,000 | 30% |
| $10,000,000 – $50,000,000 | 25% |
| Above $50,000,000 | 20% |
The tiers are marginal, like income tax brackets — only the revenue within a band is taxed at that band's rate, so a $12M-grossing game pays 30% on its first $10M and 25% on the next $2M, not 25% on the whole $12M.
