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.

Using the casino bonus calculators is easy. You just need to know three details: Bonus amount; Wagering requirement; Casino edge. If you know which game you’ll be using to wager the bonus, you can get the casino edge by substracting the game RTP from 100. Casino or house edge in general is between 2 and 8%.

How to Use the Calculator
1. Bonus Amount – Put in the value of your casino bonus. Do not include a currency symbol.
2. Rollover Amount – This is the amount that you have to rollover. The casino may express this amount as a number x the bonus, the deposit or the bonus + deposit.
3. Times to Rollover above amount – This is the number of times that you have to wager the rollover amount. The casino may state this number as 30x B or 40 x D.
4. Average RTP% – You need an idea of the average RTP% of the games that you intend to play. You will probably play a variety of games, each with a different RTP%. This is why the calculation is an estimate.
5. Average win/loss after Playthrough – The calculator will give you an amount that you will win or lose on average. This amount includes the bonus amount. So, if the amount is £25 and your bonus is £100, this means that you will have lost £75 of your bonus money but all of your deposit will be intact. If the amount is -£25, you will have lost all of your bonus and £25 of your own money on average.
