Betting Odds Calculator
Our Betting Odds Calculator simplifies the process of figuring out your potential winnings. Just enter your bet amount and odds in any format (American, Decimal, or Fractional), and the calculator will instantly show your expected profit and total payout. It also shows you what your odds look like in other formats.
Calculate Odds
Odds are crucial in sports betting. They show two things:
- The chance of an event happening.
- The payout you'll get if your bet wins.
Using the Calculator:
There are 8 fields, but you only need to fill out 2, and the rest will update automatically.
- Bet amount (required): How much you want to bet. Displayed in dollars, but you can think of it in your currency it doesn't make a difference.
- Bet type: Single bet or parlay. Choosing parlay adjusts the interface slightly.
Enter one of the following, and the calculator will fill in the rest:
- American odds: Based on win/loss relative to $100. For +250 odds, a $100 bet wins $250. On the other hand -180 odds means you need to bet $180 to win $100.
- Decimal odds: Show the total return for every unit bet. 3.00 odds means a $50 bet returns $150 total (calculation: $50 x 3.00 = $150). Your profit would be $100 ($150 total return - $50 initial stake).
- Fractional odds: Multiply your bet by the fraction to get your profit. 5/1 means a $20 bet wins $100 profit.
Implied probability: The probability of winning expressed as a percentage.
Results:
- To win: The profit you'll make based on your bet and the odds.
- Total payout: Your profit plus the amount you risked. If you bet $10 and won $50, your total payout is $60.
The odds a sportsbook gives you are based on the implied chance of the outcome. If the implied chance is lower than the true chance, it’s a good bet.
