Best Tools for Football Betting
You can gain an edge on your fellow football bettors by using some of our tools. These are the best resources for anyone interested in betting on football games:
- NFL Spread Calculator: This useful tool helps you determine whether an alternative NFL spread is attractive. For example, if the Detroit Lions are 7-point favorites to win a game, the calculator will tell you that the fair odds on Detroit -7.5 would be -114. If you can find a sportsbook offering -110 on Detroit -7.5, that could be an appealing bet.
- NFL Prop Bet Calculator: Football fans can enter the spread and total available on an NFL game to determine the expected odds on a long list of props. You can then compare the expected odds to the actual odds available on each prop at your sportsbook, which can help you identify attractive bets.
- Super Bowl Squares: This printable Super Bowl squares template will help you make any viewing party memorable.
Best Tools for Basketball Betting
These are some of the best tools at your disposal when betting on basketball:
- No-Vig Fair Odds Calculator: This tool highlights the odds you would receive if an online sportsbook did not take a house edge (vigorish) on its betting lines. You can use it to figure out which NBA betting apps take a lower house edge than their rivals in your state.
- Arbitrage Calculator: Arbitrage opportunities can arise when rival sportsbooks offer different odds on the same game. You may spot the chance to wager on both sides of the same NBA bet at rival sites and lock in a guaranteed profit regardless of the outcome. This tool can confirm arbitrage opportunities and highlight how much to wager in order to lock in the largest profit.
- Kelly Criterion Calculator: Calculate how much of your bankroll you can wager on your basketball picks based on the probability of them winning.
Best Tools for Baseball Betting
Sharp baseball bettors use a wide range of tools to augment their handicapping skills. These are some of the best resources for MLB fans:
- Futures Calculator: Enter the odds available on each team to determine the true probability of them winning the World Series, the pennant, or the division. You will also be shown the true odds if no vigorish was taken, which can help you find attractive odds when you shop around.
- Parlay Calculator: This tool highlights the payout you should receive on a successful parlay. You can use it to check if your sportsbook is offering you a fair deal on your MLB parlays.
- Arbitrage Calculator: Opportunities to exploit arbitrage can sometimes occur when you compare the MLB lines at rival sportsbooks. Use this tool to check whether you have found an arbitrage opportunity and determine how much you should wager on either side of the bet.
Best Tools for Hockey Betting
If you would like to bet on hockey games, consider using these tools:
- Three-Way No Vig Calculator: Hockey bettors can use this calculator to figure out the odds you would receive on a three-way moneyline bet if the sportsbook did not charge any vigorish. This can help you determine which sportsbooks are taking a low house edge and which sportsbooks are charging excessive juice.
- ROI Calculator: This tool allows you to measure your expected return on investment when placing hockey wagers.
- Odds Calculator: Many hockey writers and handicappers are based in Canada and often use decimal odds. This calculator quickly converts the odds to the American format.

Sports Betting Tools FAQ
The best sports betting tools include our fair odds calculator, ROI calculator, and arbitrage calculator. You can use these tools to improve your handicapping skills, find the best odds on your picks, and capitalize on weak lines at online sportsbooks.
Capitalizing upon arbitrage opportunities is the only sports betting strategy that will earn you a guaranteed profit. This approach, also known as dutching, requires you to cover both sides of the same bet at rival online sportsbooks.
If there is a significant discrepancy between the odds they offer, you can lock in a guaranteed profit regardless of the result. However, arbitrage opportunities are rare, so you need to be patient and conduct extensive research.
The smartest way to bet on sports is to practice sensible bankroll management. Only wager a small percentage of your bankroll on each pick. Conduct detailed research before making your picks, stick to markets that carry a low house edge, and shop around for the best odds and lines at multiple online sportsbooks.
Certain sports betting tools can help you beat the sportsbooks. For instance, our arbitrage calculator will highlight the ideal amount you should wager on each side of a bet after spotting an arbitrage opportunity. Other tools, such as our ROI calculator and futures calculator, can improve your chances of success.
The oddsmakers at online sportsbooks assess each team or player’s strengths and weaknesses. They also factor in variables (such as home advantage, fatigue, injuries, and so on) and then release odds on each potential outcome.
The odds tell you the implied probability of each bet succeeding. For example, odds of -125 imply a 55.56% chance of success. However, favorites often lose, so it is important to carry out extensive research before placing wagers.
