Blackjack Side-Bet EV Calculator

Every modern blackjack table offers side bets. Most are terrible — house edges from 3% to 35%. This calculator quantifies the cost of each common side bet so you can decline them with conviction. None of them, except occasionally Lucky Ladies on a fresh shoe, are worth your money.

$89.60

$0.28 expected loss per hand on this side bet. Lower than slots, but still 10× a base BJ bet.

Why side bets exist

Side bets are pure profit centers for the casino. They look fun, pay big jackpots occasionally, and most players who try them once will try them again. The math is brutal — even a 'low' 5% side-bet edge is 10× the base BJ edge.

When are side bets countable?

Lucky Ladies, Perfect Pairs, and 21+3 are theoretically countable with specialized side counts (queens for Lucky Ladies, suit composition for 21+3). The edge gain is small and the heat is high — almost no advantage player bothers anymore. Treat side bets as -EV recreation only.

FAQ

What's the worst blackjack side bet?

Lucky Ladies, depending on paytable, has the highest house edge — up to 25%. Insurance is the most insidious because dealers prompt you to take it on every Ace upcard.

Is Insurance ever a good bet?

Only if you're counting and the true count tells you the dealer's hidden card is more likely a 10 than statistical expectation. For the basic-strategy player, never take insurance.

Can side bets be counted?

A handful are. Lucky Ladies (count queens), 21+3 (count suit composition), Over/Under 13 (count low cards). The edges gained are typically 1-3% and casinos watch for these counts. Not worth the heat for most players.

Why does the dealer always offer side bets?

Dealers earn higher tips from players who bet side bets (more action, bigger pots). The casino's house edge on side bets is typically 5-25× the base BJ edge — a tiny fraction of side-bet revenue easily funds the comp tier upgrades dealers and casinos use to keep players betting.

Are progressive side bets better?

Sometimes — when the jackpot grows large enough, the EV can briefly turn positive. Track-and-pounce on progressives is its own niche. For casual play, the meter is almost never high enough to make the bet worthwhile.
