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.

Most people have a general idea of what a bankroll is, but for a post like this, we need to get a lot more specific.
Your bankroll is the amount of money you’ve set aside to gamble with.
You might have specific bankrolls for various games based on various goals. If you play games where you’re satisfied with a negative expectation, the size of your bankroll compared to the averagesize of your bets is what determines how long you’re able to play a specific game.
If you’re a professional gambler, though, you’re probably more interested in avoiding going broke in the short run. Gambling is based on random chance, and even if you have a long-term advantage,you can still go broke in the short run because of variance.
Here’s a simple example of how that might work.
Suppose you’re playing a simple gambling game with a buddy where you have a 52% probability of winning, and she has a 48% probability of winning. She’s willing to bet you straight-up, too — ifyou win, you get $100 from her, and if she wins, she gets $100 from you.
Suppose you only have a bankroll for this game of $100.
Can you see how you’d have a good probability of going broke even though you have a distinct mathematical edge?
In the long run, your results should resemble the mathematical, theoretical prediction, but in the short term, anything can happen.

The goal of having a large bankroll relative to your bet size is to avoid going broke while you’re waiting for your long-term edge to kick in.
But that only applies to gamblers who have an edge.
