This page estimates the EV of using a slot model: for each slot in the bundle, we calculate probability × average price and add the contributions. Below, you'll find the breakdown, sources, and historical EV (30/90 days if available).

EV is the expected monetary return of opening a booster, computed as the sum of slot contributions (probability × average price per pool).
We use a slot-based model. For each slot (e.g., common/uncommon/rare/foil), we multiply the chance of each pool by its average price and sum the results.
We start with Magic: The Gathering and expand to more TCGs. Prices are tracked in multiple currencies.
Daily. We refresh prices every 24 hours and keep a public history of EV changes.
