## How these numbers are built

1. Units: Steam-purchase reviews only (key activations excluded) times a release-cohort multiplier, 40-75x depending on release year. Cohorts from 2020 on are calibrated against 182 sales milestones announced by the developers themselves; older cohorts follow the published Boxleiter tables.
2. Price: an effective price that accounts for lifetime discount depth and Steam regional pricing, not the US list price.
3. Net: VAT (~13%), refunds (~9.5%) and Steam's 30% cut are removed, so roughly 55% of gross reaches the developer. Every dollar figure on this site is net to the developer.

Estimates carry a +/-30-50% error range per title and are tighter in aggregate. They are built from public signals only (Steam reviews and review history, store metadata, developer announcements, price and discount history, public build dates) and are directional, not financial statements.

Famous titles and actively operating major publishers are excluded by design: this is the long tail nobody is watching.
