| Stage | USD/month |
|---|---|
| Gross storefront sales | $166 |

## Missed seasonal-sale revenue (modeled)

Skipped 6 Steam seasonal sale window(s) in the last 10 months. Running a -50% discount in those windows is modeled at +$199 net in total, assuming a unit uplift of x3.0 (industry-typical for old catalog titles). Same ±30-50% error range applies.

## 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.
