Bankroll Tracker
Track your betting bankroll, log bets, and monitor performance over time.
Why Track Your Bankroll?
Bankroll management is the single most important discipline in sports betting. Tracking every bet helps you understand your true win rate, ROI, and whether your strategy is profitable over time. Setting a unit size (typically 1-5% of your bankroll) prevents you from risking too much on any single bet. Without tracking, it is easy to overestimate wins and underestimate losses. A detailed log also reveals which bet types, sports, or strategies work best for you, allowing you to refine your approach with real data.
Frequently Asked Questions
How big should my starting bankroll be?
Whatever you can afford to lose entirely. Start with an amount where losing it wouldn't affect your finances or relationships.
What's a unit and what should mine be?
A unit is your standardized bet size, typically 1-2% of bankroll. Smaller units = more variance protection but slower growth on +EV bets.
How is my data stored?
Locally in your browser only. We never see your bets - they're saved in localStorage on this device.
What's a good win rate to target?
Depends on the prices you bet. At -110 you need 52.4% to break even; at +100 you need 50%; at +200 you need 33.3%. Win rate alone is meaningless without price context.
