How to Calculate the Over/Under in Sports Betting

If you’re new to sports betting, then the term ‘over/under’ might mean nothing to you. However, if you’ve been betting for a while, then you’ll know exactly what it means.

Basically, the ‘over/under’ is used to compare the scores of two (or more) sporting events. To make an over/under bet, you have to decide how much you want to risk on each of the outcomes. You may want to put the same amount on each of the outcomes, or you may want to adjust your bet according to how confident you are in the outcome. Either way, the over/under is a very useful concept in sports betting. Let’s take a look at how to calculate and use the over/under in your own sports betting strategy.

The Over/Under Formula

The basic over/under formula is derived from the combination of the over/under principles used in sports. Let’s say you want to bet on the total number of points scored in an upcoming NBA game. Using the over/under formula, you would guess at the combined score of the game (for example, if the teams are tied at the end of the third quarter, then the total number of points will be a draw. In this case, the bet would be a push, as there was no clear winner in the third quarter).

If you apply the over/under formula to the fourth quarter, then the combined score of the game becomes a definite winner. For example, if the game ends in a 105-105 tie, then the bettor would win 5 points (105 – 95 = 10 points).

Let’s say you want to take a chance on the total number of goals in a college football game. You would guess that the game will end in a draw, so you place a $10 wager on the under. Unfortunately, your pick scores only 2 goals, so you lose your $10.

What if you were certain that the game would end in a tie? In this case, you would win $10 because there was an over under bet. However, if the game ends in a 3-3 tie, then you would lose $10, as well. Your final loss/gain would be $2 (2 goals minus 3 goals is 1 goal), which is half of your initial stake. You would never risk more than you can afford to lose in any situation. This is why the over/under formula is a great way to analyze games and decide what to do with your wagers.

Adjusted Odds

If you’re new to sports betting, then chances are, you’ve only ever used the basic over/under formula. However, there are times when you wish you could adjust the odds of an event to make them more favorable to either side of the bet. This is where the concept of ‘adjusted odds’ comes in.

An adjusted odds, or ‘lay’, allows you to modify the mathematical formula used for calculating the over/under. For example, if you think the over/under odds of an NBA game might be a little high (they usually are), then you can adjust them to make it more favorable to bet on the over. This is a common practice among bettors, as many times the over/under odds are set too high, making it almost impossible to win even when you’re properly lined up with a push.

An adjusted odds bet is a great way to make up for a bad streak of bad luck or an unlucky day at the tables. Just remember, you can only adjust the odds of an open game. This way, the bookie will not charge you exorbitant fees for the altered lines, as they are already included in the original odds.

Example

Let’s say you’re interested in placing a wager on the total number of points scored in the next NBA game. Using the basic over/under formula, you would guess at the combined score of the game (for example, if the teams are tied at the end of the third quarter, then the total number of points will be a draw. In this case, the bet would be a push, as there was no clear winner in the third quarter).

If you want to adjust the odds of this game to make it more favorable to bet on the over, then you can search for the closest game in terms of its lines and take a peek at its adjusted odds. In this case, you’ll notice that the game has 3.5 points spread, and the over/under odds are 1.9, so your chance of winning is 36% (1.9 divided by 3.5, rounded down). If you think this game will end in a tie, then you can confidently place a $10 wager on the under, as the over/under odds are 10-1, which means you’ll win 10 cents if the game ends in a tie and lose 10 cents if the game ends in a score.

What this example shows is that you can easily use the internet to find information about the over/under odds of any sporting event. In addition, you can use these found odds to create a small spreadsheet, which will make it easier for you to keep track of your winnings and losses. In essence, the over/under is a great tool for analyzing and deciding what to do with your wagers and creates a perfect environment for novice and experienced bettors alike.
