Units
A normalized measure of bet size relative to bankroll, used to track and compare results independent of actual dollar figures.
A unit is a normalized measure of bet size representing a fixed percentage or dollar amount of a bettor’s bankroll. Instead of reporting outcomes in raw dollars, bettors express both stakes and results in units. This convention makes performance comparable across bettors operating very different bankrolls. A bettor with a $500 bankroll and one with a $50,000 bankroll can each report being “up 15 units” for the season even though the underlying dollar profits diverge sharply.
The standard practice defines one unit as 1% to 2% of the total bankroll. Once the unit is set, every wager is stated as a multiple of it. A baseline play might be one unit, while a higher-confidence position might be two or three units. This framework enforces discipline in bet sizing by compelling the bettor to reason in proportional terms rather than chasing arbitrary dollar figures.
Example
A bettor holds a $5,000 bankroll and sets one unit at 2%, or $100. Across one week, the bettor books 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). The net is +$30.91, or about +0.31 units. Tracking in units lets this bettor benchmark weekly performance against someone staking $20 per unit on a $1,000 bankroll, since both measure outcomes on the same proportional scale.
Key Points
- Enables fair comparisons: Units let bettors compare records and strategies without knowing each other’s bankroll size, making them the common language of betting performance.
- Promotes responsible sizing: Defining a unit as a small percentage of bankroll keeps any single wager from risking too much, lowering the odds of catastrophic loss.
- Results should be tracked in units: Logging every bet in units rather than dollars yields a cleaner performance history that deposits, withdrawals, and unit-size changes do not distort.
- Confidence-based scaling: The unit system absorbs varying confidence by allowing one-, two-, or three-unit wagers within a structured framework.
- Beware inflated claims: When auditing someone else’s record, check whether large unit plays are deployed selectively to inflate results, since routinely staking five or ten units carries far more risk.
