Your bankroll is the total you're prepared to bet with, kept apart from money for bills and savings. It should be an amount you can afford to lose.
Your unit size comes from it, usually 1% to 2% per bet. Good bankroll management means betting a consistent share, not chasing losses with bigger bets.
Even good bettors go through drawdown periods, so a bankroll needs to survive long losing runs.
How it works
A bankroll is the foundation of responsible betting. It should be money you can afford to lose completely without it affecting your bills, savings or life.
Keeping it separate matters. Many bettors use a dedicated account or set amount, so it's clear how they're doing and they never top up from money meant for something else.
Good bankroll habits:
- Bet a small, fixed share. 1% to 2% per bet keeps any single loss small.
- Decide your rules in advance. Whether you recalculate your unit monthly or keep it fixed, choose before you start.
- Don't chase losses. Raising stakes to win money back is the quickest way to lose a bankroll.
- Expect losing runs. Even good bettors go through drawdown periods because of variance.
If your bankroll runs out, that's a signal to stop, not to reload. Setting deposit limits on sportsbook accounts can help you stick to your plan. Help is available if betting stops feeling fun.
Examples
- Example 1
A $500 bankroll with 1% units means $5 per bet. Ten losses in a row costs $50, or 10% of the bankroll.
- Example 2
A bettor who recalculates monthly starts at $500 with $5 units. After a bad month the bankroll is $450, so the unit becomes $4.50.
