Blackjack winnings are subject to the federal income tax and, in some states, a state tax. On a federal tax return, you must report gambling income on Line 21 ('Other Income') of IRS Form 1040. If you received any other form of compensation as a result of gambling — such as prizes, or comps issued by a casino — you must state its value.
This casino game return and variance calculator tells the expected return of an online casino bonus and chance of gain. You can use this calculator as an aid when contemplating on your bet size or checking if your results were within normal variance while playing usual casino games like blackjack, video poker, roulette etc.
The following tables display expected returns for any play in blackjack based on the following rules: dealer stands on a soft 17, an infinite deck, the player may double after a split, split up to three times except for aces, and draw only one card to split aces. Based on these rules, the player's expected value is -0.511734%.

Blackjack Betting Rule Of Thumb. If you are just a casual blackjack player who enjoys going to the casino every so often for a few hours of play blackjack, there is a very simple rule of thumb when it comes to betting. This rule of thumb does not depend on any betting or counting system and it works very well.

Introduction

The purpose of this calculator is to estimate the probability of ruin, given a positive expected value, standard deviation, bankroll, and infinite play. The calculator assumes the player flat betting and the odds of every trial are the same. The question the calculator answers is what is the probability the player would run out of money, as opposed to growing his bankroll forever. Here is some explanation of each field.

Advantage — The player advantage of the bet. For example, in full pay deuces wild, which has a return of 100.762%, the player advantage is 0.00762. Please put the advantage in decimal form, as opposed to a percent.
Standard deviation — The square root of the variance of each bet. For example, in full pay deuces wild this value is 5.08.
Bankroll — If you lose every bet, this is the number of bets you could make before running out of money. In other words, the amount of money you can risk divided by the amount of each bet. For example, if you had $5,000 and were to play video poker at $1.25 a bet, your bankroll would be $5,000/$1.25 = 4,000.
Risk of ruin — Leave this blank. When you click calculate the program will provide an estimate of the probability of running out of money. The alternative is growing the bankroll forever.

Disclaimer: This calculator produces an ESTIMATE only. The greater the bankroll size, the more accurate this estimate will be. In games like video poker, video keno, and slots, where the worst case scenario is losing one unit, I believe this calculator to overstate the chance of ruin.
