FREQUENTLY ASKED QUESTIONS

  • Bet odds are calculated by bookmakers using the formula: Odds = 1 / Probability * Bookmaker's Margin. This formula ensures that the bookmaker makes a profit. Higher odds indicate a lower chance of the event occurring, and vice versa. To calculate potential payouts, multiply your bet by the odds.

  • To calculate the edge in sports betting, subtract the implied probability from your assessed probability for a bet. Edge = Your Probability - Implied Probability. A positive edge suggests a potentially profitable wager, while a negative edge indicates an unfavorable bet. It's a crucial concept for making informed betting decisions.

    Or just use our Implied Probability Calculator and that will do the hard work for you. 

  • To calculate a bet payout, multiply your bet amount by the odds. Payout = Bet Amount x Odds. For instance, if you bet $100 on 2.00 odds, your potential payout is $200, including your initial stake. Understanding this calculation is essential for managing your betting finances.
  • To calculate a round robin bet, follow these steps:

    1. Select multiple teams or events you want to bet on.
    2. Determine the bet type (e.g., parlay or teaser) and the number of teams in each grouping.
    3. Calculate the number of bets within the round robin using combinations.
    4. Place individual bets on each combination.

    Or just use our free Roun Robin Calculator and this will do all of the hard work for you. 

  • To calculate a horse racing bet, follow these steps:

    1. Choose the type of bet (e.g., Win, Place, Show, Exacta, Trifecta).
    2. Decide on the amount you want to wager.
    3. Find the odds for your selected horse(s).
    4. Multiply your bet amount by the odds to calculate the potential payout.
  • To calculate American betting odds, first you must recognize the sign (+ or -). Positive odds reflect profit on a $100 bet (+150 means $150 profit). Negative odds show the amount needed to win $100 (-200 means $200 wager). To calculate potential winnings on a different bet size, use this formula: Profit = (Bet Amount / 100) x Odds. 

  • To calculate arbitrage betting opportunities, follow these steps:

    1. Identify two or more bookmakers offering different odds on the same event.

    2. Calculate the implied probabilities for each set of odds using the formula: Probability = 1 / Odds.

    3. Check if the total implied probabilities for all outcomes are less than 1 (100%).

    4. If so, place bets on all outcomes proportionally to guarantee a profit.

     

    Or, just simply use our free Arbitrage Calculator and it will do all of the above for you.

  • Certain side hustles, such as ProfitDuel, require zero marketing efforts to make money. 

    However, for those that do, these five key aspects can be crucial when developing a marketing strategy:

    1. Define Audience: Identify and understand your target customers.
    2. Online Presence: Build a professional website and use social media for visibility.
    3. Content & Social: Share valuable content and engage on social media platforms.
    4. Networking: Connect with potential clients through events and communities.
    5. Promotions: Offer discounts, collaborate, and gather testimonials for credibility.
  • To calculate juice in sports betting, subtract the implied probability from 100%. Implied probability is the odds converted to a percentage. For example, if the odds are -110, the implied probability is 52.38%. So, 100% - 52.38% = 47.62%, which is the juice or vigorish.

    Or just use our simple Vig Calculator and it will do all of the hard work for you.

  • To calculate ROI in sports betting, use this formula: (Net Profit / Total Investment) x 100. Net profit is your winnings minus total wagers. ROI is expressed as a percentage. For example, if you profit $500 from $1,000 wagers, your ROI is 50%. This simple formula helps assess your betting success.
