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.
