The size of your bankroll is definitely important to your success when playing blackjack. If you’ve ever played the game, you know that there are winning and losing streaks. If you have a desire to remain in the game and not go broke, having a bankroll big enough to survive the losing streaks is essential.

The Kelly Criterion is the method most gamblers use to gauge their bankroll size. It’s a bet-to-bankroll ratio system that tells you how big the bankroll should be to play at a certain level. The equation is too long to show here, so a rule of bringing 50 bets to the table for a three-hour session will hold you over until you learn the Kelly Criterion.

That’s only for one session. You should carry a bankroll of 300-400 bets and you should have it divided into sessions. And follow your win/loss limits every time.
