How to read this tool
Soft 17 matters
Dealer hitting soft 17 usually increases the house edge compared with standing on soft 17.
Bankroll impact is volume
A small edge can still cost meaningful money when average bet size and hands per hour are high.
Important disclaimer
This calculator gives approximate rule-based estimates for educational use. Exact blackjack house edge depends on full rules, deck penetration, strategy, side bets, number of players, cut card placement, and local procedures. No strategy or calculator guarantees profit.
