How to Use The Calculator
Our sports betting calculator is extremely easy to use; all you need to do is enter your wager amount with the odds of the bet, and the calculator fills out the rest.
You can use our calculator to bolster your sports betting strategy by learning exactly what your risk and potential rewards are before you place your bet.
- Wager: This is the amount of money you wish to place on the bet.
- American Odds: American odds are displayed as +/-, with the minus (-) indicating the favorite. These odds are based on $100 bets: A $120 bet at -120 pays $120, while a $100 bet at +120 pays $120.
- Decimal Odds: Decimal odds describe the total return for every dollar wagered, including what you risked: 2.4 odds include 1 for your base bet, and 1.4 for every dollar risked. $100 successfully wagered on 2.4 odds pays $240.
- Fraction Odds: Fraction odds show you much you can win by multiplying your bet by the fraction. A successful $10 bet at 6/1 would win you $60, and a successful $10 wager on 20/21 odds would win $9.52.
- Implied Odds: You can enter your American, decimal, or fractional odds into the calculator to see the implied odds of your bet winning. For example: -5,000 odds have a 98.04% implied probability of winning, while +5,000 odds have a 1.96% implied probability of winning.
- Bet Type: Single bet or parlay; by default the calculator is set to single bet.
- To Win: This represents how much you stand to win if your bet is successful.
- Total Payout: The total payout includes both your initial wager and your winnings; it is how much overall money you’d receive if your bet is successful.
