Everyone has their preferences, and in the betting world, you will find three types of MLB odds, which we have listed below:

  • American (Money Line)
  • Fractional (British)
  • Decimal (European)

American Odds (Money Line)

It’s common practice in Pennsylvania to use American odds, commonly known as money line odds or US odds. These are the default odds you’ll be looking at when researching MLB betting lines. In short, a plus (+) or negative (-) sign will be seen next to the MLB odds.

How to Calculate Your MLB American Odds Payouts

Let’s bring two MLB teams into the equation to help give you a real-life betting situation. We will put the Detroit Tigers up against the Kansas City Royals with the following odds:

Detroit Tigers -150

Kansas City Royals +125

Most moneyline bets give the bettor a clear view of either the amount they need to bet to win $100 or how much they would win from a $100 bet.

  • The negative number shows how much you need to bet to receive $100 in winnings. A $150 bet on the Detroit Tigers to win would result in a $100 profit (total payout of $250).
  • The positive number indicates how much you would win from a $100 bet. In this case, a $100 bet on the Kansas City Royals to win would result in a $125 profit (a total payout of $225).

Some people find replacing $100 with $1 amounts more convenient when calculating MLB betting lines. Here, you will gain $1 if you bet $1.50 on the Detroit Tigers to win.

Wagering $1 on the Kansas City Royals would return $1.25. Using this method, you can easily multiply up or down depending on the bet amount to calculate your profit potential on your MLB odds.

Fractional Odds

It is rare to come across fractional odds when checking MLB betting lines, but that is not to say you will never see them. If you do, the easiest way to look at them is like this: “how much you can win / how much you bet”. These odds are occasionally used in the Futures market.

How to Calculate Your MLB Fractional Odds Payouts

For example, the LA Dodgers to win the next World Series before the season starts could be priced at 4/1. 

A $100 bet on 4/1 odds would return $500 ($400 in profit plus your $100 bet).

Punters can also find the numbers reversed, indicating an “odds-on” bet, or in other words, a favorite. Let’s say the LA Dodgers to beat the Detroit Tigers is calculated at 2/7.

A $100 bet on 2/7 odds would return $128.57 ($28.57 in winnings plus your $100 bet).

Decimal Odds

Decimal odds are a lot easier to work with than fractional odds. Essentially, the numbers you see represent multipliers. The smaller number indicates the favorite out of the MLB odds, while the bigger number indicates the underdog.

Let’s bring back the Detroit Tigers vs. Kansas City Royals game to help shed some more light on decimal odds:

Detroit Tigers 1.66 (favorite)

Kansas City Royals 2.25 (underdog)

How to Calculate Your MLB Decimal Odds Payouts

With decimal MLB odds, the total payout amount is calculated by multiplying the bet by the decimal value. In this example, a $100 wager at odds of 1.66 would return a payout of $166. Due to the inclusion of the opening bet amount, your total profit would be $66.

Understanding Odds & MLB Betting Lines

You must learn to appreciate how the popular markets work to succeed and earn profits across MLB betting lines. Only then will you be able to accurately read MLB odds and pick out the high-value bets that bring home bigger and more frequent winnings. We have listed all the top MLB betting markets below, giving you an insight into where you should put your money.

MLB Moneyline Odds

Your only task in this popular betting market is to pick the winning team, but the prediction is complicated by several baseball-linked factors.

Key points include the starting pitchers changing from game to game and the bullpens affecting the outcome. It is also quite challenging to forecast the point when batters reach their peak performance over such a long season.

“The unpredictability of baseball could find MLB playoff odds showing a play-off bound team at only -150 favorites, while a mediocre underdog team could still be around the +125 mark.”

MLB Run Line Odds

You have probably heard of point spread betting and covering the spread in NFL and NBA. MLB gets its own version in the shape of the run line. Due to the low-scoring games found in baseball, run lines are often based on +1.5 and -1.5, with these numbers representing runs.

MLB odds for run line betting can be so tight that it can often swing a favorite into underdog territory and vice versa.”

MLB Over/Under Totals Odds

Looking for MLB odds on the total number of runs can go either way, from close pitching duels ending in 1-0 or 2-1 scores to a 9-8 nail-biter if the batters are on their game.

In most cases, the over/under total runs line will be between 7.5 and 10.5, while alternative betting totals will provide you with a wider range, usually sitting anywhere from 5 to 16.

“The over/under runs total betting market is a great alternative when you can’t decide which MLB team will win.”

A lot more potential for bigger returns, but this is notoriously hard to predict. The Most Valuable Player is often based on statistics, and it is rarely ever a pitcher.

Deciding on how many home runs or if there will be at least one brings more of a fun side to betting, although there is still good money to be made in this exciting market.
