| Stage | USD/month |
|---|---|
| Gross storefront sales | $972 |
| After VAT / sales tax (-13% blended) | $846 |
| After refunds (-9.5% median) | $766 |
| Net to developer (after Steam 30%) | $536 |

## Monthly review counts, oldest to newest (24 months)

20, 12, 10, 8, 4, 12, 6, 7, 5, 9, 12, 8, 6, 9, 5, 3, 5, 10, 4, 8, 6, 7, 8, 10

## Estimated acquisition range

$12.9k to $25.7k (2-4x the trailing net annuity of $6.4k/year). Same 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.
