Everything you need to use this tool with confidence.

Watch the 2-minute walkthrough

The Risk of Ruin Simulator calculates how likely it is that your bankroll will be completely depleted.

Many sports bettors focus exclusively on their edge or their hit rate.

The problem?

Even a profitable strategy can fail if the bankroll is too small or the stakes are chosen too aggressively.

With this calculator you can simulate how hit rate, odds, stake size and bankroll affect your long-term risk of survival.
