Betting Odds Calculator - NFL, NBA, MLB Sports Betting

A betting odds calculator is a tool to determine the potential payout from a given wager based on specified odds. They are particularly useful for novice and experienced bettors who wish to learn the potential returns and profits from a particular bet that they would like to place.

Certain betting odds calculators such as the AceOdds calculator can also calculate multiple selections and convert odds to different formats including American (moneyline), decimals and fractions as well as calculating the implied probability of your specified odds.

A single bet is the simplest form of betting. You predict the outcome of an event by picking a single result. For example, a single winner of an NFL game.

A double bet is simply two selections from different events. To make a return, both selections need to win. For example, picking two winners in two different basketball games.

A Treble bet is similar to a Double, but with three selections, from different events where all three of your selections need to win to receive a return.

A parlay is a bet that combines two or more selections into a single wager that has a payout only when all parts win. Should a single wager lose, the payout is zero.

A Canadian bet consists of 26 bets on five selections. You place 10 Doubles, 10 Trebles, five Four-Fold parlays and one Five-Fold parlay. The Canadian bet does not include singles, so at least two of your selections must be successful to receive a return on the bet.

You can convert American odds to decimal odds by using different formulas depending on whether the American odds are positive or negative. See the formula for positive and negative odds below:

Positive American Odds (e.g. +200):
Formula: Decimal Odds = 1+ (American Odds/100)
Example: If the American odds are +200, the conversion to decimal would be:
Decimal Odds = 1+(200/100) = 1+2 = 3.00

Negative American Odds (e.g. -150):
Formula: Decimal Odds = 1+(100/American Odds)
Example: If the American odds are -150, the conversion to decimal would be:
Decimal Odds = 1+(100/150) = 1+0.6667 ≈1.67
