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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $612 |
| After VAT / sales tax (-13% blended) | $533 |
| After refunds (-9.5% median) | $482 |
| Net to developer (after Steam 30%) | $337 |

## Monthly review counts, oldest to newest (7 months)

3, 18, 4, 0, 2, 1, 0

## Estimated acquisition range

$8.1k to $16.2k (2-4x the trailing net annuity of $4.0k/year). Same error range applies.

## Markets by review language

- schinese: 14% (game NOT localized in this language)
- french: 7% (game NOT localized in this language)
- german: 7% (game NOT localized in this language)
- english: 66%
- russian: 3% (game NOT localized in this language)
- spanish: 3% (game NOT localized in this language)

Localization gap: 34% of measured reviews are written in languages the game does not support (top: schinese). 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.
