The amount a player can expect to win or lose if they were to place a bet on the same odds many times over, calculated through a simple equation multiplying your probability of winning with the amount you could win per bet, and subtracting the probability of losing multiplied by the amount lost per bet.

What is EVS in betting terms?
At its most basic, EVS stands for “evens”. In short, it means the sports betting market on something where the two opponents are likely to be very evenly matched. It is nearly impossible to predict a winner, and so the betting odds on a bet become even between the home and away sides.
How do you calculate value odds?
Calculating Value Bet Odds and Probabilities
 First, find the bookmaker probability percentage of a sports bet by dividing 100 by 2.4.
 Second, find the true probability by checking various odds and finding the average.
 Lastly, minus the bookmaker probability by true probability and divide by the bookmaker probability.
What is the formula for calculating EV?
Can be as follows: EV Formula = Market capitalization + Preferred stock + Outstanding debt + Minority interest – Cash and cash equivalents.

What is the formula for value betting?
A value bet is a bet where you believe that the odds of an event happening are greater than the odds offered by the bookmaker. The value of a bet is calculated using the formula: Value = (Odds * Odds)  1. If the resulting value is greater than 0, it is considered a value bet.
Frequently Asked Questions
How to calculate expected value?
In statistics and probability analysis, the expected value is calculated by multiplying each of the possible outcomes by the likelihood each outcome will occur and then summing all of those values. By calculating expected values, investors can choose the scenario most likely to produce the outcome that they seek.
How do you find the value of a sports bet?
For example, you would make a value bet when you consider a basketball team to have a 60% chance of winning, but the odds offered imply they have only a 40% chance (approximate decimal odds of 2.50). That is: Value = (0.60 * 2.5)  1 = 1.50  1 = 0.50 (being greater than 0 is value).
What is the Excel formula for expected value?
In an empty cell, enter the formula =SUMPRODUCT(Value, Probability) . Press the enter key to calculate the expected value.
What is the expected financial value of a bet?
Feedback: The expected financial value of a bet is the probability of winning times the net gain of winning minus the probability of losing times the net loss of losing. There are 4 Aces out of 52 cards in a standard deck, so the probability of drawing an Ace and winning this bet is 4/52 = 1/13.
What is Wager expected value?
The formula is: Expected Value = (Winning implied probability % * profit if bet won) – (Losing implied probability % * stake). If the calculated number is positive, that means the bet has a positive expected value and if we simulated that event an infinite number of times you would always net a profit.
How do you interpret expected value?
Understanding Expected Value
Essentially, the EV is the longterm average value of the variable. Because of the law of large numbers, the average value of the variable converges to the EV as the number of repetitions approaches infinity. EV is also known as expectation, the mean or the first moment.
Is EV betting profitable?
Positive EV Betting Pros: Positive EV betting strategies can lead to consistent longterm profits. If a bettor can consistently identify odds that don't match the true implied probability, the profits will stack up over time.
FAQ
 What is 80% rule EV?
 Simply, the 2080% rule suggests keeping the battery of an electric vehicle charged between 20% and 80% of full capacity. It's a method of electric vehicle charging meant to improve battery life. Think of it as the green zone.
 How do you calculate expected value on a bet?
 To calculate EV on a bet you need to multiply the probability of winning by the potential payout, then subtract the probability of losing multiplied by the amount wagered. Alternatively, you can use a betting odds converter to enter implied probability for the odds and then compare.
 What is the formula for the expected value?
 NOTE. To find the expected value, E(X), or mean μ of a discrete random variable X, simply multiply each value of the random variable by its probability and add the products. The formula is given as E ( X ) = μ = ∑ x P ( x ) .
 What is the expected value of multiple bets?
 The amount a player can expect to win or lose if they were to place a bet on the same odds many times over, calculated through a simple equation multiplying your probability of winning with the amount you could win per bet, and subtracting the probability of losing multiplied by the amount lost per bet.
 How do you calculate expected value in football?
 The amount a player can expect to win or lose if they were to place a bet on the same odds many times over, calculated through a simple equation multiplying your probability of winning with the amount you could win per bet, and subtracting the probability of losing multiplied by the amount lost per bet.
 How do you find the expected value of the winnings from a game?
 The expected value of a game of chance is the average net gain or loss that we would expect per game if we played the game many times. We compute the expected value by multiplying the value of each outcome by its probability of occurring and then add up all of the products.
 How do you find positive expected value in sports betting?
 The formula is: Expected Value = (Winning implied probability % * profit if bet won) – (Losing implied probability % * stake). If the calculated number is positive, that means the bet has a positive expected value and if we simulated that event an infinite number of times you would always net a profit.
How to calculate ev in sports betting
What is the math formula for sports betting?  For an underdog, the equation is 100/(odds +100) x 100. So a +150 underdog would be calculated as 100/(150 + 100) x 100. That equals 40, meaning a +150 underdog has an implied win probability of 40 percent. For fractional odds, the equation is denominator/(denominator + numerator) x 100. 
What is the 80% rule for EV?  Simply, the 2080% rule suggests keeping the battery of an electric vehicle charged between 20% and 80% of full capacity. It's a method of electric vehicle charging meant to improve battery life. Think of it as the green zone. 
Does positive EV betting actually work?  Positive EV indicates that a bet is expected to yield a profit over the long run, while a negative EV suggests the bet is likely to result in losses. Successful EV betting bettors are skilled at identifying these opportunities, but of course, the bet has to actually win in order to see gains over time.

How do you calculate EV with American odds?  (Probability of Winning) x (Amount Won per Bet) – (Probability of Losing) x (Amount Lost per Bet)

What is the formula to calculate American betting odds?  For positive odds, simply divide by 100. Therefore, American odds of +300 become 3/1 (300 / 100). For negative odds, the calculation is 100 divided by the American odds. Therefore, American odds of 300 become 1/3 (100 / 300). 
 What is expected value in betting?
 Expected value is a predicted value of a variable, calculated as the sum of all possible values each multiplied by the probability of its occurrence. In betting, the expected value (EV) is the measure of what a bettor can expect to win or lose per bet placed on the same odds time and time again.
