How to use a sports betting odds calculator
The sports betting calculator above allows you to see various outputs such as decimal odds, implied win probability, amount returned on a bet (or “payout”), and bet profit.

You can use the odds calculator a few different ways:
- Convert odds from American to Decimal
- Convert American odds to an implied win probability percentage
- Return the profit of a given bet if it wins
The betting odds calculator will work for all types of bets: point spread, moneyline, total, or props. For any bet that has a handicap value set (ex: a point spread of -6, total of 43, etc.), you can ignore that part and simply enter the odds associated with that bet.

Moneyline Odds Calculator
Take for example the following matchup and associated moneyline odds to win the game:
Minnesota Vikings (+260) at San Francisco 49ers (-330)
I have bolded the moneyline odds to make it obvious what we are looking for. If you wanted to place a $10 bet on the San Francisco 49ers at -330, you could enter -330 in the odds calculator above.
You would see the following information as a result. Odds of -330:
- Decimal odds = 1.30
- Implied win probability = 76.7%
- $10 bet = $13.03 payout
- $10 bet = $3.03 profit
Point Spread, Total (Over/Under), and Props
Let’s say you wanted to bet a different market on the same game. Using the Vikings/49ers example, we have the following markets:
Point Spread: Vikings +7 (-110) at 49ers -7 (-110)
Total: Over 44.5 (-120), Under 44.5 (+105)
Prop: Kirk Cousins TD Passes: Over 2.5 (+165), Under 2.5 (-190)
I have highlighted the actual odds you would enter for any of the given markets. Despite each example above representing a different bet, they all have odds that you can enter into the calculator.

Why is this useful?
Knowing the implied odds of a bet is extremely useful if you are doing your own modeling. If you have a model that says the San Francisco 49ers have a 79% chance to win the game, you could compare that to the implied win probability to see how it compares.

Odds Calculator And Payout American Odds
Calculating betting odds will depend on which odds format you used to place your bet: American, Decimal, or Fractional odds. Most bettors in the United States will use American odds. Each odds format represents the same thing: the percent chance of winning.
To calculate this percentage, convert odds from American to Decimal. Then take 1/Decimal odds to calculate the implied chance of winning. You can also calculate the bets payout, profit, and more.
