Convert Probability To Odds Ratio
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)

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.
While most models are unlikely to be sharper than the market number, it is a useful comparison point to see how your “number” compares to the market. Using odds calculators are a good way to check how your numbers stack up.
How do I calculate betting 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.
