Unit

Definition:

In sports betting, a unit is a standard measurement of bet size, usually set as a percentage of a bettor’s total bankroll. Using units instead of dollar amounts makes it easier to track performance and manage risk consistently, regardless of bankroll size.

They serve two main purposes:

1. Standardize bet sizing so results can be compared across bettors with different bankrolls.

2. Help manage risk by limiting exposure on any single wager.

Real-World Example

• A bettor has a $1,000 bankroll and decides 1 unit = $25 (2.5% of bankroll).

• They place:

  • A 1-unit bet on the Packers –3.5 (–110) for $25.

  • A 2-unit bet on the Chiefs moneyline (–150) for $50.

• Tracking results in units (e.g., +3 units, –1 unit) shows performance independent of actual dollar value.
