🎲 Parlay EV Calculator

Analyze multi-leg parlays: For each leg, enter YOUR win probability (from your model/analysis) and the OFFERED odds (from the sportsbook). The calculator shows your edge on each leg. ⚠️ Only parlay if ALL legs show positive edge!
⚠️ Important: This calculator assumes legs are INDEPENDENT. If legs are from the same game or correlated, this analysis is INVALID.

🏈 Teaser EV Calculator

Teaser Strategy: Adjust spreads/totals in your favor by "buying" points. All legs must win for the teaser to pay out.
⚠️ Important: This assumes legs are INDEPENDENT. For same-game teasers, correlation invalidates this analysis.
🎯 Wong Teaser (NFL): Favorites -7.5 to -8.5 teased to -1.5 to -2.5, or underdogs +1.5 to +2.5 teased to +7.5 to +8.5 (crossing key numbers 3 & 7).
