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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $2.8k |
| After VAT / sales tax (-13% blended) | $2.4k |
| After refunds (-9.5% median) | $2.2k |
| Net to developer (after Steam 30%) | $1.5k |

## Monthly review counts, oldest to newest (21 months)

81, 27, 11, 12, 137, 58, 25, 20, 45, 52, 23, 8, 25, 12, 11, 15, 14, 11, 14, 9, 10

## Missed seasonal-sale revenue (modeled)

Skipped 4 Steam seasonal sale window(s) in the last 21 months. Running a -50% discount in those windows is modeled at +$8.7k net in total, assuming a unit uplift of x3.0 (industry-typical for old catalog titles). Same ±30-50% error range applies.

## Markets by review language

- french: 0%
- german: 0%
- english: 14%
- russian: 4%
- spanish: 2%
- schinese: 29%
- koreana: 38%
- japanese: 12%
- brazilian: 1% (game NOT localized in this language)

## 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.
