Units
A standardized bet-size measure tied to bankroll, used to track and compare results independent of dollar amounts.
A unit is a standardized bet-size measure equal to a fixed percentage or dollar amount of a bettor’s bankroll. Instead of reporting results in raw dollars, bettors express stakes and outcomes in units. That convention makes performance comparable across bankrolls of wildly different sizes. A bettor working a $500 bankroll and one working $50,000 can both say they are “up 15 units” on the season, even as the dollar totals diverge sharply.
The usual approach defines one unit as 1% to 2% of the total bankroll. With the unit fixed, every wager is stated as a multiple of it. A routine play might be one unit, while a higher-conviction play runs two or three units. This structure disciplines bet sizing by forcing proportional thinking rather than chasing arbitrary dollar figures.
Example
A bettor holds a $5,000 bankroll and sets one unit at 2%, or $100. Across a week they make four wagers: a one-unit win at -110 (profit of $90.91), a one-unit loss at -110 (loss of $100), a one-unit win at +140 (profit of $140), and a one-unit loss at +100 (loss of $100). Net result: +$30.91, or about +0.31 units. Reporting in units lets this bettor stack their week against someone betting $20 per unit on a $1,000 bankroll, since both measure against the same proportional yardstick.
Key Points
- Enables fair comparisons: Units let bettors weigh records and strategies without knowing each other’s bankrolls, the standard language of betting performance.
- Promotes responsible sizing: Fixing a unit as a small slice of the bankroll keeps any single wager from risking too much, cutting the odds of a ruinous loss.
- Results should be tracked in units: Logging every bet in units rather than dollars yields a cleaner history undistorted by deposits, withdrawals, or unit-size changes.
- Confidence-based scaling: The system flexes for conviction, allowing one, two, or three units while staying inside a defined framework.
- Beware inflated claims: When sizing up someone’s record, check whether large unit plays are deployed selectively to pad results, since routinely staking five or ten units carries far more risk.
