This definitive guide to positive EV bets will explain its pros and cons and how to use this technique to exploit incorrect bookmaker odds to return an average profit rate every time. When you know the best odds, you stand to maximize your return.

What Is Expected Value Betting?

The expected value of a bet is the predicted value of a variable. It is the sum of all possible value multiplied with the probability of its occurrence. With +EV sports betting, you can expect a profit over time.

But keep in mind that there is both a neutral and a negative expected value in betting. Below, we’ll give you some practical examples with bets. For now, let’s consider the following example:

Amount won per bet x the probability of winning – Amount lost per bet x the probability of losing

Let’s take the coin toss for an example of how to calculate expected value. If the coin and toss are fair, then each outcome (heads/tails) has an equal chance of 50%. Therefore, the odds on a fair market would have odds of 2.0.

This would give you an EV value of 0 for either a tails or heads. The probability of both outcomes is equal, so if you tossed a penny infinitely, it would theoretically be all square.

However, if you are offered 2.15 odds that the coin will land on heads, then this is a value wager.

If you place $10 on the coin landing at 2.15 on heads, the EV will be calculated similarly to that above.

Pre-Match & Live Expected Value Betting

Positive expected value (+EV), betting is when you place bets with a higher chance of winning than the odds. Odds Scanner US +EV screens will show you profitable bets that have a mathematical advantage over a specific sportsbook.

Odds Scanner US uses odds from the best sportsbooks in the world to calculate the expected profit margin. This is also known as “fair value” or “true odds.”

Value betting or positive expected value betting is only for those who are able to manage risk and tolerate variance. You must be prepared for downswings as a +EV sports bettor. However, since all your wagers have positive expected values, it is mathematically impossible to predict that you will make a profit over the long term.

How to Calculate EV in Sports Betting - 4 Simple Steps

Sportsbooks would be out of business if all bettors bet only on +EV bets. But sports bettors don’t have a way to know which bets will have positive expected values. Some bettors trust their algorithms while others monitor injury news.

Still, others have a better understanding of the market and can calculate EV betting when it’s time for them to “buy low,” which allows them to beat the closing line.

Check out our EV betting example guide below to get a better understanding of how it works.

  1. Convert your Odds to the Implied Probability.

    Using Odds Scanner US, convert your odds to American, Decimal, and Fractional odds by simply entering them. It will calculate the implied probability of winning and the profit if it wins.

  2. Calculate the Potential Winnings or Losses.

    A $100 bet at +200 in American odds (1/2 fractional or 1.50 decimal) has a 66.67% implied probability and a potential profit of $50. This is not the total return which would include your original wager amount. If it wins, a $100 bet at +200 American odds (2/1 or 3.00in decimal) has the potential of making $200.

  3. Use the EV Betting Math Formula.

    Horse racing and futures markets are the most common uses of fractional odds. These are essentially simple math: Divide one number by another, then multiply that sum by your bet amount.
    The odds of winning more than the original wager will be paid if the bigger number is divided by the smaller number, ie, 3/1. However, if the smaller number (ie: 3/1) is divided by the greater number, then the odds of winning will be less than the original wager.

  4. Check If the Value is Negative, Positive or Neutral.

    American odds can be presented in thousands or hundreds of numbers and are categorized by the assigned value. It is easy to imagine American odds calculation as currency exchanges in increments of $100.
