Whereas the Trip Calcs screen deals with Trip-length "sessions," the Risk-of-Ruin Calcs screen calculates statistics from a "lifetime" bankroll perspective. It starts by requiring the same input as the Trip Screen - "Win/100" and "SD/100," either entered or copied in from other BJRM screens.

After supplying a "lifetime" Bank amount, in "units," and clicking on the "Calculate" button, several risk and expectation-related statistics will be displayed, including: the classic Lifetime Bank Risk of Ruin value; the number of hands and hours that must be played in order for the "units won" expectation to result in a doubling of your starting Bank; and six statistics that represent the number of hands and number of hours that will have to be played for expectation to equal +1sd, +2sd, and +3sd results.

Solve For Required Bank, Given a target ROR

This section, given a $$ Unit value and the level of Risk exposure you are prepared to live with (e.g. 5%, 10%, etc), will instantly tell you the number of Units and $$ Bank you will need to have underwriting your play. In addition, to help in comparing the "value" of different approaches to different games, the "% Return on Bank per 100 hnds" played (or observed, if back-counting) is shown. This statistic can be useful in weighing the value of your "time" spent in the casino, as it "normalizes" comparative data that may be based on different sized Banks and/or Units, and different playing strategies, such as "play all" versus "wonging."

And, as with the other BJRM screens, you can print the screen image by clicking on the "Print Screen Image" button.
