Sports betting can be a great way to make money, but it can also be a great way to lose money. If you’re new to sports betting, or if you’re looking to improve your betting ROI (return on investment), it’s important to know how to calculate ROI.

There are a few different ways to calculate ROI, but the most common is simply dividing your net profit by your total investment. For example, if you bet $100 on a game and you win $110, your ROI would be 10%.

However, this method doesn’t take into account the vigorish (the bookmaker’s cut), which is why it’s important to also use a second method of calculation that takes the vig into account.

To do this, you’ll need to know the odds of the bet you placed as well as the size of the bet. For example, let’s say you bet $100 on a game with odds of +200. This means that for every $100 you bet, you will win $200 if your team wins. In this case, your net profit would be $100, and your ROI would be 100% (($100-$100)/$100).

However, if the odds were -200 (meaning you would have to bet $200 to win $100), your net profit would be $0, and your ROI would be 0% (($0-$200)/$200).

It’s important to remember that these are just two simple methods for calculating ROI. There are other factors that can affect your ROI such as bonuses, promotions, and cash back offers from your sportsbook. But if you can master these two methods, you’ll be well on your way to making money from sports betting.

What is ROI?

ROI in sports betting is calculated in the same way as it is in any other investments. It is simply the difference between the amount of money you put in and the amount of money you get back. The higher the ROI, the better the investment.

There are a few things to keep in mind when calculating ROI for sports betting. First, it is important to remember that not all bets are created equal. Some bets will have a higher ROI than others. Second, it is important to remember that past performance is not necessarily indicative of future results. Just because a team has won a lot of games in the past does not mean they will continue to do so in the future. Finally, it is important to keep track of your own personal win percentage. This will help you gauge how successful you are at picking winners.

Assuming you are able to pick winners at a 55% clip, a $100 bet on each game would yield a $550 profit over the course of a season. This would give you a 5.5% ROI. However, if you were only able to pick winners at a 50% clip, that same $100 bet would only yield a $500 profit over the course of the season. This would give you a 5% ROI. As you can see, even just a small difference in win percentage can have a big impact on your overall ROI.

Keep in mind that these numbers are just for illustrative purposes and your actual results may vary depending on how good you are at picking winners, what types of bets you make, and other factors.

How to Calculate ROI for Sports Betting

Many people who are new to sports betting don’t know how to calculate ROI, or return on investment. ROI is a very important number because it tells you how much money you’re making for every dollar you risk. In this article, we’ll show you how to calculate ROI for sports betting.

Find the right bet size

There are a few simple steps you can take to make sure you’re betting the right amount on each game, and thus maximizing your ROI.

First and foremost, you should always know how much you’re comfortable losing on each bet. This is your bankroll, and it should be separate from the money you use for living expenses. How much you decide to risk is up to you, but as a general rule, you shouldn’t risk more than 5% of your bankroll on any single bet.

Once you know your bankroll, you can figure out how much to bet on each game by using the Kelly Criterion. This formula takes into account your win probability and the odds of the bet to determine how much of your bankroll you should stake on the wager.

For example, let’s say you have a bankroll of $1,000 and you’re betting on a game where the odds are -110 (meaning you have to bet $110 to win $100). Using the Kelly Criterion, we can calculate that you should bet 4.55% of your bankroll on this particular wager, which would come out to $45.50.

You can also use Kelly betting for making multiple bets on different games. In this case, you simply need to sum up all of the individual bet sizes and make sure that the total doesn’t exceed 5% of your bankroll. So if we had two bets with the same odds as above (-110), we would add up both Kelly percentages to get 9.1%. This means we would bet $91 on both games combined, which is still below our 5% threshold.

Of course, not every sportsbook allows players to bet using Kelly staking (also called “proportional betting”). In these cases, many sharps will reduce their stake size slightly so they don’t run into any limits. A common reduction is to divide theirKelly percentage by two, which still gives them a very good chance of growing their bankroll over time while minimizing their downside risk.

Use the Kelly Criterion

The Kelly criterion is a formula used to determine how much of your bankroll you should stake on a given bet. The basis of the Kelly criterion is that you should bet an amount that has the highest probability of making you money in the long run.

To calculate the Kelly criterion, you need to know three things:

-The probability of winning the bet
-The payouts for winning and losing the bet
-Your bankroll (the amount of money you have to gamble with)

Once you have these three pieces of information, you can use the following formula:

Amount to Bet = (Probability of Winning * Payout for Winning) – (Probability of Losing * Payout for Losing) ———————————————————— – (Probability of Winning * Payout for Winning) + (Probability of Losing * Payout for Losing) – 1

Use value betting

The first — and perhaps most important — step in becoming a winning sports bettor is to focus on value betting.

What is value betting? It’s simple: you are looking for bets where you believe the odds are in your favor. In order to find these bets, you need to have a keen understanding of both the odds and the underlying probability of the bets you are placing.

This might sound like a lot of work, but there are tools available that can help. One popular tool is called the Kelly criterion, which is a formula that helps you determine how much of your bankroll you should bet on each individual wager.

There is no perfect betting system, but if you can focus on value betting and learn to manage your bankroll effectively, you will give yourself a much better chance of success in the long run.


The Bottom Line
Many factors go into ROI calculation for sports betting. Professional bettors often use models that are much more sophisticated than the one described here.

The important thing is to make sure that you’re factoring in all of the elements that affect your bottom line. If you’re not, you could be leaving money on the table.
