## Where a gross dollar goes (monthly, at current velocity)

| Stage | USD/month |
|---|---|
| Gross storefront sales | $11.9k |
| After VAT / sales tax (-13% blended) | $10.3k |
| After refunds (-9.5% median) | $9.3k |

## Markets by review language

- koreana: 2%
- russian: 20% (game NOT localized in this language)
- japanese: 2%
- english: 76%

Localization gap: 20% of measured reviews are written in languages the game does not support (top: russian). Localizing is likely immediate market expansion.

## Methodology

Units are estimated from Steam-purchase reviews times a release-cohort multiplier, 40-75x by year. Cohorts from 2020 on are calibrated against 182 sales milestones announced by developers; older ones follow the published Boxleiter tables. Revenue uses an effective price (lifetime discounts and regional pricing) and nets out VAT (~13%), refunds (~9.5%) and Steam's 30% cut: roughly 55% of gross reaches the developer.
