How converter works?
American odds to decimal formula
Positive Decimal = (American odds / 100) +1
Negative Decimal = (100 / American odds) +1
Decimal odds to american formula
Odds 2.0 or more American = (Decimal odds -1) * 100
Between 1.01 and 1.99 American = -100 / (Decimal odds - 1)
Decimal odds to implied profitablity formula
(1/ decimal odds) * 100 = implied probability
American odds to implied profitability formula
Positive 100 / (positive American odds + 100) * 100 = = implied probability
Negative Negative American odds / (Negative American odds + 100) * 100 = implied probability
FAQ
A betting odds calculator is a tool that helps you calculate potential payouts, implied probabilities and returns for different types of bets, such as single or parlay bets, using various odds formats.
Choose the correct odds format from the dropdown list in the calculator block.
- American: Positive or negative numbers show potential profit or the amount you need to bet.
- Decimal: Shows the total return (including stake) per $1 wagered.
- Fractional: Shows the profit relative to your stake.
Betting odds show the likelihood of an outcome and how much you can win. Higher odds mean a less likely outcome but bigger payouts.
Multiply your stake by the odds:
- Decimal: Payout=Stake×Odds
- Fractional: Add your stake to the profit shown by the odds.
Multiply the decimal odds of all selections together, then multiply the result by your stake. For fractional or American odds, convert them to decimal first.
Fractional odds show the profit relative to your stake. For example, 3/1 means you win $3 for every $1 wagered.
