Basic Strategy tells you what to do (Hit or Stand), but it doesn’t tell you how likely you are to win. Sometimes the correct move still results in a loss 60% of the time (e.g., Hard 16 vs 7).
This Hand Equity Calculator reveals the raw probability. Select your hand and the Dealer’s upcard to see your true win percentage.
BJ Equity
Understanding Your Edge
Knowing your equity helps manage tilt. If you know that a “20 vs 7” only wins 77% of the time, you won’t be as shocked when the dealer draws a 21 to beat you.
Key Scenarios
- 21 (Player BJ): 100% Win (unless dealer also has BJ).
- 20 vs 8: ~88% Win. (Dominating position).
- 12 vs 2: ~35% Win. (This explains why this is such a frustrating hand, even though “Stand” is sometimes valid).
Frequently Asked Questions (FAQ)
Does this assume I play perfectly?
Yes. The win probabilities shown assume you follow Basic Strategy for the remainder of the hand. If you make deviations (like standing on 11), your equity drops significantly.
