Definition

The total amount of money a bettor has set aside for wagering. Managing your bankroll is crucial – it’s the funds you can afford to lose in betting without financial harm. All betting decisions (like unit size) revolve around the bankroll.

Formula

Example

If a bettor’s **bankroll** is \$1,000, they might decide that each unit (standard bet) is 1% of that (\$10). A disciplined bettor will adjust bet sizes according to bankroll changes and avoid risking too much of the bankroll on any single wager.
