Expected Value Calculator for Sports Betting (May 2025)

The Positive EV betting calculator helps you to make sharper bets against the sports betting sites. When using the EV calculator, you can identify wagers that can give you the edge over the house. This is sophisticated software that can scan all the latest odds and identify value every time. 

A growing number of bettors are now making Positive EV bets. This means a greater chance of landing a return on investment over time. The good news is that sports betting calculators, such as a positive EV calculator, take away the hassle and time needed to find these bets. We will explain how the +EV betting calculator from OddsJam works – this company is the pioneer behind these trading tools.

This guide will provide lots of information when it comes to +EV betting. We’ll explain how this works, including the calculations to arrive at the best value wagers.

Customers should always look for a positive EV with their sports bets. Getting the expected value every time gives you a greater chance of beating the sportsbooks. 

You take the odds for a betting selection and the stake you’re looking to place. You also need to know the probability of this outcome winning. When this data is entered into a calculator, you can assess whether there is a positive expected value. Expected value will be there if the odds involve a bigger payout than the actual probability suggests. 

Let’s give you a simple example. If you were offered +110 on a coin toss and you were staking $50, then you would have an expected value of $5. That is because you have the edge on a bet where there’s always a 50% chance of the outcome happening. 

Positive Expected Value Betting is a strategy used by skilled sports bettors and gamblers to make bets that are expected to be profitable. This is a data-driven principle that uses mathematics to make calculated bets.

A Positive EV betting calculator will help you achieve this aim regularly. We always want the odds to provide a bigger potential payout than the probability suggests. The best indicator of probability is from the sharpest sportsbook, or it might be from another data source. 

Imagine you wager $200 on the New England Patriots +110 moneyline at DraftKings Sportsbook. That would give you a potential return of $420 if the bet won. However, another sportsbook might have -105 moneyline odds for the Pats instead. The latter would imply that no commission odds would be +100, and they have a 50% probability of winning. Therefore, the above bet would provide an expected value of $10. 

It’s clear why +EV betting is important to sports bettors. Rather than sportsbooks having a house edge, +EV betting turns the tables and gives you a better chance of a return. Although winning is never guaranteed, placing EV bets is the smarter way to wager because it’s a data-led approach where you take the emotion out of your betting choices. Instead, you can use statistical information to inform your sports betting. 

If the Boston Celtics are playing the Orlando Magic in the NBA, they might be -133 on the Moneyline. Those NBA odds imply that they are 57% likely to win the game. However, you might have the probability of 60% probability instead. A $200 bet would therefore mean an expected value of $10. If the probability was even higher at 65%, then the positive EV would be $27.50. Therefore, it’s all about finding odds that far exceed the actual probability. 

The standard formula for expected value is: EV = (Probability of Win) x (Profit if Win) + (Probability of Loss) x (Stake). This is the formula in the OddsJam +EV betting calculator. It’s therefore a case of entering the data into a positive EV calculator to assess certain odds.

You need to find the biggest odds for the selection you want to back. You can use the best sports betting apps odds to get this. You can enter the odds along with your proposed stake. It’s also the case that you will need a precise probability of an outcome happening.

When it comes to EV gambling, it’s always good to understand the vig. The vig is the house edge that is built into every sports bet. 

If you are betting on a point spread market, both the Miami Heat and the Denver Nuggets might be listed at -110. However, if there was no juice, then each side would be +100 instead, as they have a 50% chance of winning on this market. 

EV gambling aims to lower the vig by making selections at fair odds. To do this, you need to find the best odds first. Although a no-commission bet is rare, the sportsbooks will differ when it comes to the odds provided. It’s therefore all about finding picks at the right prices.

To partake in EV plus betting, we recommend you use a Positive Expected Value Calculator. This will tell you two things. Firstly, whether there’s a positive EV for a pick. Secondly, the amount of expected value that exists. 

The first step is to find a pick at the biggest possible odds, whether this is an NBA or NFL game, or any sports or betting market you enjoy betting on. Then, you can decide on how much you want to stake. 

Using the positive EV betting calculator, you can then enter the probability of this pick winning. To understand the probability, it determines the fair odds of the bet. The sharpest sportsbook is a useful guide in ensuring that you know the overall probability. This will then yield the positive expected value if any exists.

There are many sportsbooks where you can sign up for an account. It’s recommended that you hold accounts with as many as possible. This is because they all offer several types of bets. They also differ in terms of the odds that are available for the same selection. This is where you can take advantage and experience EV plus betting.
