How to Use the Moneyline Calculator

Using this calculator is simple. Here’s what each field means and how to use it:

Inputs

  • Convert From – Choose the odds format you want to start with:

    • American (Moneyline): Odds like -110 or +150 commonly used in U.S. sportsbooks.

    • Decimal: Odds like 1.91 or 2.50, popular in Europe and with online books.

    • Fractional: Odds like 3/2 or 5/1, traditional in the U.K. and horse racing.

  • Enter Odds – Type in the odds you see at your sportsbook in the format you selected above. Example: -120, 2.10, or 5/2.

  • Enter Bet Amount (optional) – If you want to see how much you’d win with a specific stake, type your wager amount here (e.g., 10, 50, 100). If you leave it blank, the calculator will just show conversions and implied probabilities.

Outputs

  • Decimal Odds – Converts your input into decimal format. Easy to read: just multiply your stake by the decimal to see your total return.

  • American Odds – Converts your input into U.S. moneyline odds. Positive numbers (+150) show how much profit on $100; negative numbers (-200) show how much you must stake to win $100.

  • Fractional Odds – Shows the odds as fractions (e.g., 3/2). These represent “profit to stake.” Example: 3/2 means profit of $3 for every $2 wagered.

  • Implied Probability – The percentage chance of winning implied by the odds. For example, -110 odds = 52.38% chance. This helps you compare your own handicapping to the sportsbook’s line.

  • Total Payout – If you entered a bet amount, this shows your total return (winnings + stake).

  • Profit – Shows the net winnings (your payout minus your original stake).

Example: If you enter American odds -110 and a $50 stake:

  • Decimal Odds: 1.91

  • Fractional Odds: 10/11

  • Implied Probability: 52.38%

  • Total Payout: $95.45

  • Profit: $45.45
