How We Calculate

We use the Boxleiter method, which estimates sales by multiplying review count by a factor that varies based on price:

Free games: ~100x reviews
Under $5: ~60x reviews
$5-$10: ~45x reviews
$10-$20: ~35x reviews
$20-$30: ~25x reviews
Over $30: ~20x reviews

Revenue is calculated after Steam's ~30% cut. Actual results may vary based on regional pricing, sales, and bundles.
