- Chance of beating the dealer
- Expected value of standing, hitting, doubling down, or splitting
- Review Suggested Move:
The calculator suggests the optimal move based on statistical probabilities. - Repeat for Multiple Hands:
Practice with different hands to improve strategic understanding.
Formulas and Calculations in Blackjack
The Blackjack Calculator uses probability theory and combinatorics to calculate outcomes. Here are the key formulas:
1. Probability of Busting
P(Bust) = Number of Cards That Cause Bust ÷ Total Remaining Cards
- Example: If your hand is 16 and 6 cards remain that would cause a bust, P(Bust) = 6 ÷ remaining deck cards.
2. Probability of Winning
P(Win) = ∑ P(Player Hand Outcome) × P(Dealer Outcome)
- Calculates combined probability of winning considering all possible dealer hands.
3. Expected Value (EV)
EV = ∑ (Outcome × Probability)
- Outcome: +1 for win, −1 for loss, 0 for tie
- Probability: Likelihood of each scenario occurring
- EV determines whether standing, hitting, doubling down, or splitting is statistically advantageous.
4. Doubling Down and Splitting
- Doubling Down EV = 2 × Probability of Winning on One Additional Card
- Splitting EV = Sum of probabilities for two separate hands after split
Step-by-Step Example
Example: You hold 10 and 6, dealer shows 9
Step 1: Input your hand: 10 + 6 = 16
Step 2: Input dealer upcard: 9
Step 3: Calculator provides:
- Probability of bust if hit: 62%
- Probability of winning if stand: 42%
- Suggested move: Stand (based on basic strategy)
✅ Result: Standing is statistically the safer choice.
