Bets are often listed in units rather than dollars for standardized and consistent bankroll management. This approach helps bettors maintain a disciplined strategy by risking a consistent percentage of their overall bankroll on each wager.

For example, if someone has a $1,000 bankroll and defines one unit as $10 (1% of their bankroll), a bet of 3 units means they are risking $30 on that particular wager. Using units allows for better tracking of performance, risk management, and emotional control, as the focus remains on the percentage of the bankroll at stake rather than the dollar amount.

Example: If a bettor with a $1,000 bankroll places a bet of 2 units, it means they are risking $20 (2 units * $10 per unit). This standardized approach ensures that the bet size is proportionate to the bettor’s bankroll.

The plus (+) and minus (-) symbols in American odds represent the potential profit or loss associated with a bet. The plus sign indicates the potential profit on a $100 wager, while the minus sign indicates the amount one needs to bet to win $100. For example, +150 odds mean a $100 bet could yield a $150 profit, while -200 odds imply that one needs to wager $200 to win $100 profit. Understanding these symbols is crucial for assessing the potential returns and risks associated with different bets.

For example, if a wager has odds of +200, a $100 bet could result in a $200 profit if the team wins.

ROI stands for Return on Investment, and in the context of sports betting, it represents the profitability of a betting strategy. It is calculated by dividing the net profit from bets by the total amount invested and expressing the result as a percentage. A positive ROI indicates a profitable strategy, while a negative ROI suggests losses. For instance, if a bettor invests $1,000 in bets and ends up with a $300 profit, the ROI would be 30%.

A bettor with an initial bankroll of $1,000 places bets totaling $500 and ends up with a profit of $200. The ROI is calculated as (Profit / Investment) * 100, which is (200 / 500) * 100 = 40%
