Being able to convert betting odds into percentages is a major part of knowing how to read odds.

By knowing the percentage of the time you need to win a bet to break even, you can decide whether it is a smart bet to make. If you believe something has an 80% chance of occurring but the odds suggest it has a 50% chance of occurring, you have a positive expectation wager. If you believe something has an 80% chance of occurring but the odds suggest it has an 85% chance of occurring, it’s a bad bet to make because you have no edge.

Below are the formulas to convert moneyline betting odds to percentages, convert fraction betting odds to percentages, and convert decimal betting odds to percentages.

### How to convert moneyline betting odds

Moneylines can come in ‘plus’ (favourites) and ‘minus’ (underdogs) formats, so there are two different formulas to convert moneylines into percentages.

For ‘plus’ moneylines, the formula is: 100 / (Moneyline + 100)

If the moneyline is +110, the formula would look like this:

100 / (110+100) = 100/210 = 0.476

Multiply your end result (0.476) by 100 to get the percentage: 47.6%

For ‘minus’ moneylines, the formula is: Moneyline / -(100 – (Moneyline))

If the moneyline is -130, the equation would look like this:

-130/ – (-130 -(-100)) = -130 / -230 = 130/230 = 0.565

Multiply your end result (0.565) by 100 to get the percentage: 56.5%

### How to convert fraction betting odds

Fraction betting odds are easier to convert into an implied winning percentage.

For fraction betting odds, the formula is: Denominator / (Denominator + Numerator)

If the fraction betting odds are 11/10, the formula would look like this:

10 / (11+10) = 10 / 21 = 0.4761904

## Odds To Percent Converter

Multiply your end result (0.4761904) by 100 to get the percentage: 47.6%.

### How to convert decimal betting odds

Decimal odds are the easiest to convert into a percentage.

For decimal betting odds, the formula is: 1 / decimal odds

If the decimal betting odds are 2.10, the equation would look like this:
1 / 2.10 = 0.4761904

Multiple your end result (0.4761904) by 100 to get the percentage: 47.6%.

With esports betting becoming more and more popular, it’s good to know about the different types of esports odds. These odds come in several forms. In this article I will take you through the basics so that you may fully understand what the various esports betting sites are showing you.

The three main types of esports betting odds are the following:

## 1. Decimal Odds

Decimal odds are called decimal because they come in decimal form.

Examples include: 1.80, 2.40, 4.00 and so on.

The meaning of these odds is very simple: your total returns are whatever the odds show you multiplied by the amount you wagered. So if you bet \$5 that team A will win the match and team A’s odds of winning are 1.80, you get a return of 5 * 1.80 = \$9. If you wager \$20 on a team whose odds are 4.00, the amount you get in case of a win will be 20 * 4.00 = \$80.

Two things you’ll want to know here is how to convert odds to percentage and how to convert odds to probability.

### Decimal Odds to Percentage

Another way of understanding decimal odds is using percentages.

So instead of 1.80, think of this as 180%. Instead of 2.40, think 240%. And 4.00 would actually mean 400%.

Of course, these percentages include the amount you’ve wagered. So it’s not 180% profit but 180% returns. The profit is actually just 80%. In the second case, the profit is 140%. In the third it’s 300%.

So you always have to decrease your initial amount or 100% in order to find what you’re actually making.

### Decimal Odds to Probability

If you want to find out the win probability of a given bet in the bookmaker’s assessment, just do it this way: 2.00 is exactly 50%. Anything below that is less than 50%. Anything above that is more than 50%.

The general formula for turning decimal odds to probability is this: 100/odds.

If a team’s odds of winning are 5.00, their estimated chance of winning is 20%.

Of course, all of this is true in the bookmaker’s assessment. But that doesn’t mean it’s 100% correct. In fact, sometimes you will find the real favorite regarded as the underdog, simply because the bookmaker doesn’t understand what’s going on. These are the situations in which you can make a lot of money.

Ultimately, you shouldn’t be worried about what the bookmaker is telling you and simply assess the situation yourself, using your own esports knowledge and seeking bets that give you good risk/reward ratios.

## 2. Fractional Odds

Fractional odds look like this: 5/1, 8/1, 2/1 and so on. Their general form is x/y, which means this: you make a profit of x dollars for every y dollars you wager.

So in the first example (5/1), you make \$5 for every \$1 you wager. And that’s just your profit. The total amount you get back is actually \$6 (your profit plus the dollar you wagered).

Just like with decimal odds, you’ll want to know how to convert odds to percentage and how to convert odds to probability.

### Fractional Odds to Percentage

When turning fractional odds to percentage in order to calculate profitability, the general rule is to determine how many dollars you get for each dollar you wagered and then multiply that with 100. That will give you your profit in percentages.

## Betting Odds To Percentage Calculator

So in the first case (5/1), you’d get a profit of 500%, while your total returns would be 600%.

But let’s take a more difficult example, such as 7/2. In this case, you’d get a profit of \$7 for each \$2 you wagered. To figure out the percentages, just divide 7 by 2 and then multiply with 100. What you’d get is 700/2 or 350%.

### Fractional Odds to Probability

If you want to turn fractional odds to probability in order to figure out the win probability of a given team according to the bookmaker, just use the following formula: given the odds of n/m, the number you’re looking for can be found like this: (m/(m+n)) * 100.

For example: 4/1 would give us (1/(4+1)) * 100 or (1/5) * 100 or 100/5 or 20%.

Davis vs gamboa prelims. ATLANTA – Undefeated two-time super featherweight world champion Gervonta “Tank” Davis (23-0, 22 KOs) successfully moved up to 135 pounds and won the WBA Lightweight Title with a 12 th round knockout of former unified champion Yuriorkis Gamboa (30-3, 18 KOs) Saturday night live on SHOWTIME in front of 14,129 fans from the award-winning State Farm Arena in Atlanta. Gamboa's questionable punch resistance should only make Davis more dangerous in that regard. Inevitably, Gamboa will enter fight-or-flight mode after being hurt and, true to his history, will be. Watch the prelims for Gervonta Davis and Yuriokis Gamboa’s battle for the lightweight title live from inside the State Farm Arena in Atlanta, Georgia. A wild scene erupted today at the Gervonta Davis vs Yuriorkis Gamboa weigh in. Tank Davis missed weight and shoved Gamboa HARD during their face off. As of this writing, Davis is a -1500 favorite (a \$1,500 wager pays \$100), and Gamboa is a +800 underdog (a \$100 bet pays \$800). Earlier in the week, Davis was as much as a -3000 betting favorite.

## 3. American Odds

These types of odds are the most unusual and difficult to grasp at first, because it’s hard to deduce what they mean unless someone explains them to you.

And their meaning is this: when you see the minus sign (-), that’s the favorite. And the number followed by it represents the amount you need to wager to make a profit of \$100.

When you see the plus sign (+), that’s the underdog. And the number followed by it represents the profit you’ll make for every \$100 you wager.

For example:

Team A: -760

Team B: +585

If you wanted to bet on team A, for each \$760 you wagered you’d make a profit of \$100, meaning that you’d get a total of \$860 back.

If you wanted to bet on team B, for each \$100 you wagered you’d make a profit of \$585, meaning that you’d get a total of \$685 back.

### American Odds to Percentage

For underdogs, transforming American odds to percentage is simple: the odds themselves constitute the profit percentage. So in the above case, the percentage is 585%. Because you’re wagering \$100 and making a profit of \$585, So the percentage of the total return is actually 685%.

For favorites, what you do is this: you divide 10,000 by the number associated with them and you get the percentage you’re looking for.

## Odds To Percentage Calculator

In the example above, the result would be 10,000/760 = 13,15%. This would be your profit. So in total, you’d get back 113,15% of what you wagered.

### American Odds to Probability

For the underdogs, the win probability can be obtained using the same method used for fractional odds.

## Moneyline Odds To Percentage Calculator

So in our example, we’d have 5.85/1 and that would give us (1/(1+5.85)) * 100 or (1/6.85) * 100 or 100/6.85 or 14.6%. To calculate the win probability for the favorite, just subtract that from 100% and voila!
