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

| Stage | USD/month |
|---|---|

| After refunds (-9.5% median) | $61 |

## Monthly review counts, oldest to newest (15 months)

23, 3, 1, 5, 7, 9, 5, 6, 7, 2, 5, 4, 2, 6, 12

## Missed seasonal-sale revenue (modeled)

Skipped 1 Steam seasonal sale window(s) in the last 15 months. Running a -50% discount in those windows is modeled at +$21 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.
