Unit Size Formula:

A unit in sports betting represents a standardized measure of bankroll used to place wagers. The 1% rule (Unit = Bankroll/100) is a common conservative approach to bankroll management.
The calculator uses the simple formula:
Where:
Explanation: This conservative approach helps manage risk and prolong your betting bankroll.
Details: Using consistent unit sizes prevents over-betting, helps manage variance, and allows for proper bankroll growth tracking.
Tips: Enter your total bankroll amount. The calculator will determine your recommended unit size (1% of bankroll). Adjust unit size based on your risk tolerance.
Q1: Why use 1% as the standard unit size?
A: 1% provides a conservative approach that can withstand normal variance while allowing for bankroll growth.
Q2: Can I use larger unit sizes?
A: More aggressive bettors may use 2-5% units, but this increases risk of ruin during losing streaks.
Q3: Should unit size change as bankroll changes?
A: Yes, units should be recalculated whenever your bankroll changes significantly (≥20%).
Q4: What about progressive betting systems?
A: Most experts recommend flat betting (consistent unit sizes) over progressive systems which can be risky.
Q5: How does this apply to different bet types?
A: The same unit sizing applies regardless of bet type (spread, moneyline, totals), but riskier bets might warrant smaller units.
