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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $1.6k |
| After VAT / sales tax (-13% blended) | $1.4k |
| After refunds (-9.5% median) | $1.2k |
| Net to developer (after Steam 30%) | $863 |

## Monthly review counts, oldest to newest (1 months)

104

## Estimated acquisition range

$20.7k to $41.4k (2-4x the trailing net annuity of $10.4k/year). Same error range applies.

## Markets by review language

- english: 54%
- russian: 46% (game NOT localized in this language)

Localization gap: 46% 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 (Boxleiter method, 20-75x by year). 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.
