Odds Calculator 🛈

American 🛈 The format normally used in the USA. A positive value means you will win that amount if you bet $100. A negative value means you must bet that amount to win $100.

Example 1: Betting $100 on +150 odds has a potential profit of $150.
Example 2: Betting $150 on -150 odds has a potential profit of $100. Decimal 🛈 The format used in most countries. Multiplying the bet amount by the decimal odds gives you the potential total payout (wager amount + winnings).

Example 1: Betting $100 on 2.5 odds has a potential total payout of $250, profiting $150.
Example 2: Betting $150 on 1.667 odds also has a potential total payout of $250, profiting $100. Fractional 🛈 This format is used mostly in the UK and Ireland. Multiplying the bet amount by the fractional odds gives you the potential profit.

Example 1: Betting $100 on 3/2 odds has a potential profit of $150.
Example 2: Betting $150 on 2/3 odds has a potential profit of $100.
Implied (Win) Probability: 🛈 The odds provided by sportsbooks represent the chance of that wager winning. This is referred to as Implied Probability. Notice that the lower the chance of winning, the higher the potential profit.

Example 1: +150 odds represents a 40% chance that the wager will win.
Example 2: -150 odds represents a 60% chance that the wager will win.
Potential Profit: 🛈 The lower the chance of winning, the higher the potential profit.

Example 1: +150 odds potentially profits 150% of the wager amount.
Example 2: -150 odds potentially profits 66.67% of the wager amount.
