Live Blackjack: House Edge and Why Basic Strategy Matters
How big the casino's edge in live blackjack is, what basic strategy changes, and which rule differences move the number.

The edge depends on the table, not just the game
Blackjack has one of the lowest house edges in the casino, but the figure is not fixed. Under common rules and with perfect basic strategy it is usually quoted at around 0.5 percent of the amount wagered. Change the rules and it moves: a blackjack that pays 6 to 5 instead of 3 to 2 adds a large amount to the edge, and so can restrictions on doubling, splitting or when the dealer stands on a soft 17.
What basic strategy is
Basic strategy is a chart that tells you the mathematically best action for every combination of your hand and the dealer's upcard, for a given set of rules. It does not predict the next card. It simply stops you from giving the casino extra edge through hunches such as refusing to hit a hard 16 or taking insurance.
Mistakes that cost the most
- Taking insurance or even money: it is a separate bet with a worse edge than the main game.
- Standing on low totals because the dealer might bust: the chart often says hit.
- Ignoring the payout on a blackjack: always check 3 to 2 versus 6 to 5 before sitting down.
- Side bets: these tend to carry a much higher edge than the main hand.
Turning the percentage into money
The edge is an average over a very large number of hands, not a rule for tonight's session. As an illustration with assumed figures, 10 units a hand at 60 hands an hour for two hours is 1,200 units wagered. At a 0.5 percent edge that is an expected cost of about 6 units, though real results swing far above and below it.
