Bankroll management is essential for sustainable sports betting. Start small, and only bet with money that you can afford to lose. It’s also a good idea to spread your bets out in “units,” or fractions of your overall bankroll. This will ensure that you don’t place your entire bankroll on one bet, and it will help you keep your winnings in the green even when you have losing streaks.

Betting on over/under totals is a popular way to make money in sports betting. The total is set by the bookmaker to reflect the expected combined score of both teams in a game. If you think the team will win a close game and exceed the total, you’ll bet the Over; otherwise, you’ll bet the Under. It’s important to remember, however, that the over/under is never official until the end of the game.

Another way to make money in sports betting is by analyzing a team’s historical performance against the spread and over/unders. A free tool called Sharp can help you analyze team profitability and find value bets. It compares teams on the moneyline, against the spread, and on totals (over/unders). It also shows you how profitable each team is at home, on the road, when favored, or as an underdog. This data is invaluable for identifying betting opportunities.
