# How Winning Margin Betting Works

When we think about sports betting, the first thing that probably comes to mind is odds. You’ve probably seen online bookmakers offer odds on just about any sporting event, and you may have even wondered what they meant. Well, those odds aren’t what this article is about, but it’s important to know what they are. For the purposes of this article, let’s assume you are placing bets on the NFL or NCAA football games.

## Understanding Margin

Odds are a way of saying “I’ll take this side of the bet.” For example, the Over/Under line at Bookmaker.eu may list the New England Patriots as +3.5 favorites to win the next game against the Buffalo Bills. This means that for every \$100 you staked, you’ll win \$300 back in accordance with these odds. For every \$100 you lose, you’ll lose \$300.

Odds are often represented as a percentage such as +120 for the Patriots, which means they’ll win the game by a margin of 20%. The key takeaway from this is that, because the odds are in your favor, you’re basically guaranteed to win your bet. The amount you win will be based on the amount you bet plus any return on investment (ROI) the bookmaker offers.

## Using Margin To Gain An Advantage

We’ve all heard of the gambler’s fallacy, which basically means people assume that because something is likely to happen, it will happen. Using this assumption to your advantage means taking a long shot on a game and being rewarded for it. For example, if you’re +350 to win the Patriots game, you’re going to win \$100 just for taking the bet since you’re guaranteed to win. The problem is that if you win, you’ll owe massive amounts of money since you have to pay back your initial bet plus an additional \$300. The key to avoiding this situation is to make sure your ROI is high enough to make up for the massive punt you just made. In this case, you have a 7% ROI, which means for every \$100 you bet, you’ll make \$14 in profit, assuming you win.

## The SportsBetting FAQ

People often have questions about sports betting and odds, so let’s answer some of them. First, is it legal to bet on sports? Second, what kind of odds do I need to hit a profitable level? Third, how do I calculate my ROI? Let’s take a look at each question.

### Is Sports Betting Legally Banned?

The first question people often ask about sports betting is whether or not it is legal. The short answer is yes, but the specifics are a little more complicated. In most states, sports betting is considered a form of gambling, and under federal law it is considered a form of “prioritized” betting, which is generally illegal. However, the legality of sports betting will vary from state to state, so always check with the state government before placing a bet.

### What Kind Of Odds Do I Need To Hit A Profitable Level?

The second question people ask about sports betting is what kind of odds do I need to hit a profitable level? This question comes with a couple of sub-questions, including what constitutes a “profitable level” and how do I gauge whether or not I’ve reached that level?

The answer to the second question depends on how much you’re willing to risk. If you’re new to sports betting, it’s best to start out small and prove yourself before taking bigger and more lucrative bets. What this means is that you should play smaller games with smaller stakes for the first few weeks or months before going all-in on a game or season. This gives you the chance to save up money required to cover the initial bet plus any winnings, should you have them. Once you’ve proven yourself to be a profitable and trustworthy sports bettor, it may be time to take on the big leagues.

### How Do I Calculate My ROI?

The third question people ask about sports betting is how do I calculate my ROI? The short answer is profits over losses. The key to calculating ROI is to track your winnings and losses over the long term to get an accurate picture of how much you’re making and how much you’re losing. For example, if you bet \$1,000 on a game and it ends up winning, your ROI is \$1,000/\$1,000, or 100%. If you bet \$1,000 on a game and it ends up losing, your ROI is \$1,000/\$0, or 0%.

## The Bottom Line

So how exactly does winning margin betting work? As we’ve established, sports betting is considered a form of gambling under federal law, and many states prohibit the practice as well. This means you’ll want to play it safe and only bet what you can afford to lose, especially if you’re going to be placing bets on games outside of your state of residence. However, if you do decide to give sports betting a try, the key to success is to understand and use the concepts of odds and margins to your advantage. With these two elements, you’ll be able to make meaningful and profitable bets, no matter the odds or the state of legality where you play.
