Calculating expected value with American odds can be a useful tool for bettors looking to make informed decisions when placing bets. American odds are also known as moneyline odds, and they represent the amount you have to bet to win $100 or the amount you would win on a $100 bet. In order to calculate expected value with American odds, you simply need to follow a basic formula.
The formula for calculating expected value with American odds is:
(Expected Value) = (Probability of Winning x Amount Won per Bet) – (Probability of Losing x Amount Lost per Bet)
Here’s a step-by-step guide on how to calculate expected value with American odds:
1. Convert the American odds to decimal odds. You can do this by using the formula:
Decimal Odds = (100 / American Odds) + 1
2. Calculate the implied probability of winning based on the decimal odds. You can do this by using the formula:
Implied Probability = 1 / Decimal Odds
3. Calculate the implied probability of losing:
Implied Probability of Losing = 1 – Implied Probability of Winning
4. Determine the amount won per bet based on the American odds. If the odds are positive, this represents the profit on a $100 bet. If the odds are negative, this represents the amount you need to bet to win $100.
5. Determine the amount lost per bet. This is the amount you would lose on a losing bet.
6. Plug the values into the formula for expected value and calculate the result.
By calculating expected value with American odds, you can make more informed betting decisions and potentially increase your chances of long-term success in sports betting.
