Blackjack Basic Strategy EV Calculator

Understanding the Expected Value (EV) in Blackjack is crucial for serious players. EV tells you the average amount you can expect to win or lose on a particular hand if you played it an infinite number of times making the same decision.

A positive EV means the decision is profitable in the long run, while a negative EV indicates a loss. Our Blackjack Basic Strategy EV Calculator helps you quantify these expectations based on optimal play (Basic Strategy) and common casino rule variations.

Essential Blackjack Strategy Rules

Always Split

Aces and 8s should always be split, regardless of dealer up card.

Never Split

10s, 5s, and 4s should never be split. Play them as regular hands.

Double Down

11 is the best doubling hand. Also consider 10 vs weak dealer cards.

How to Use This Calculator

How to Use This Calculator

Step 1: Configure Game Rules

Set the calculator options to match your specific casino environment:

Basic Game Structure

  • Number of Decks: Most common are 6 or 8-deck shoes, though some casinos offer 1, 2, or 4-deck games
  • Blackjack Payout: Always prefer 3:2 payouts; avoid 6:5 games which significantly increase the house edge

Dealer Rules

  • Dealer Soft 17: "Dealer Hits Soft 17" (H17) is more common and worse for players than "Dealer Stands on Soft 17" (S17)

Player Options

  • Double After Split (DAS): "DAS Allowed" is better for players and more common in favorable games
  • Surrender Rule:
    • "Late Surrender" is most common when offered
    • "Early Surrender" is rare but very advantageous for players
    • "No Surrender" is the default in many casinos

Step 2: Enter Your Hand Details

Player Hand Configuration

  • Player Hand Total: Enter the numerical sum of your cards
    • For Ace + 6, enter 17 (if counting Ace as 11)
    • For 10 + 6, enter 16 (hard total)

Hand Type Selection

Choose the appropriate hand category:

  • Hard Hand: No Ace, or Ace counts as 1

    • Example: 10 + 6 = Hard 16
    • Example: Ace + 5 + 10 = Hard 16 (Ace forced to count as 1)

  • Soft Hand: Ace counts as 11 without busting

    • Example: Ace + 6 = Soft 17
    • Example: Ace + 2 + 4 = Soft 17

  • Pair: Two cards of identical rank

    • Example: 8 + 8 = Pair of 8s (total 16)
    • Example: King + Queen = Not a pair (both worth 10, but different ranks)

Dealer Up Card

Select the dealer's visible card from 2 through Ace.

Step 3: Analyze the Results

Primary Recommendation

The calculator displays the Optimal Decision according to Basic Strategy, representing the play that minimizes losses or maximizes winnings over time.

Expected Value Analysis

  • EV Percentage: Shows expected return per dollar wagered
  • Interpretation:
    • Positive EV: Profitable long-term decision
    • Negative EV: Expected loss (choose least negative option)
    • Example: -0.50% EV means losing $0.50 per $100 wagered on average

Comparative Analysis

The breakdown section shows estimated EVs for all possible actions, helping you understand the cost of suboptimal decisions.
