American Odds To Decimal
It is vital to know how to convert different betting odds so that you can play with a variety of bookmakers worldwide. In the United States of America, American odds are used, across Europe, Decimal odds are used. Fractional odds are a more traditional method that is mostly used in horse racing.
Decimal Odds – Decimal Odds, also referred to as European Odds, are used in most European countries and are the default option of many Asian bookies as well. This is the easiest odds format to understand as the odds represent how much a 1 unit wager returns. For example a €1 wager at odds.
Convert American Odds To Decimal Odds
Here is a step by step guide on how to convert the different odds types:
Decimal to Fractional conversion:
Decimal odds show the amount that a bettor can win for every $1 staked. The number indicates the total return for the better, not just the profit as is seen in the other two odd formats. Here’s an example: The Stars are 1.714 in decimal odds (-140 in American). For every $1 wagered, the bettor profits 71.4 cents, plus the original stake of $1. American odds of +200 would become 3.00 in decimal format. You multiply your stake (bet amount) by that figure in order to calculate your potential return. If you were to bet $100 at 3.00, you.
Decimal to American Odds / Moneyline Odds Converter. The Moneyline or American format if the figure quoted is positive it expresses the profit you would make from a successful bet with a $100 stake, so 200 means $200 in winnings on top of the returned $100 stake. A 200 Moneyline price is, therefore, the same as the fractional 2/1 odds, or 3.00. As the American Odds have two types, there are two methods to convert them into decimal form. For positive odds, the odds are divided by 100 and 1 is added to it. For negative odds, 100 is divided by the odds and 1 is added to it.
Let’s use a 1.75 decimal odd as an example:
- Remove 1 from the decimal odd and convert it to a fraction.
1.75 – 1 = 0.75 = 75/100 - Reduce the fraction to the simplest form.
75/100 = 3/4
3/4 is the Fraction odds equivalent of 1.75 Decimal odds.
Decimal to American conversion:
There are two methods, one for decimal odds more than 2.00 and one for decimal odds less than 2.00.
To convert a decimal odd of 2.00 or higher, let’s use 3.35 as an example:
- The moneyline equals the decimal odds minus 1 times 100.
(3.35 – 1) x 100 = +235
+235 is the American odds equivalent of 3.35 Decimal odds.
To convert a decimal odd of less than 2.00, let’s use 1.9091 as an example:
- The moneyline equals -100 divided by the decimal odds minus 1.
(-100) / (1.9091 – 1) = -109.99 = -110 - Then round the answer off into the closest round number.
109.99 = -110
-110 is the American odds equivalent of 1.9091 Decimal odds.
Fractional to American conversion:
There are two methods, one for fractional odds more than 1/1 and one for fractional odds less than 1/1.
To convert a fractional odd of 1/1 or higher, let’s use 7/4 as an example:
- Convert the fraction to decimals by multiplying it by 100.
7/4 * 100 = 1.40 - Then multiply that number by 100 again.
1.40 * 100 = +140
+140 is the American odds equivalent of 7/4 Fractional odds.
To convert a fractional odd of 1/1 or lower, let’s use 1/10 as an example:
- Convert the fraction to decimals by multiplying it by 100.
1/10 * 100 = 0.1 - Divide -100 by that answer.
-100/0.1 = -1000
-1000 is the American odds equivalent of 1/10 Fractional odds.
Fractional to Decimal conversion:
Let’s use a 3/4 fractional odd as an example:
- Convert the fraction to a decimal by multiplying it by 100.
3/4 x 100 = 0.75 - Add 1 to the decimal answer.
0.75 + 1 = 1.75
1.75 is the Decimal odds equivalent of 3/4 Fractional odds.
American to Decimal conversion:
There are two methods, one for positive (+) odds and one for negative (-) odds.
To convert a positive odd, let’s use +235 as an example:
- Divide the money line by 100.
235/100 = 2.35 - Add 1 to the previous answer.
2.35 + 1 = 3.35
3.35 is the Decimal odds equivalent of +235 American odds.
To convert a negative odd, let’s use -110 as an example:
- Divide 100 by the money line.
100/110 = 0.9091 - Add 1 to the previous answer.
0.9091 + 1 =1.9091
1.9091 is the Decimal odds equivalent of -110 American odds.
Luckily, most online bookmakers have options to convert the odds automatically, but it is always a good idea to know the maths behind odd conversions in case that option isn’t available.

Betting Odds Explained
American Odds – American Odds are the default odds format at most US friendly betting sites as well as Nevada sports books. Here odds are expressed as either a negative or a positive number. When positive the odds represent how much a player will profit on a successful $100.00 wager. So for example if the odds are +180 a successful $100 bet will return $280 (the $100 stake + $180.00 win). When the odds are negative they represent how much a bettor must stake to win $100. Therefore $150 staked at -150 returns $250.00 (the $150 stake + $100 win).
Decimal Odds – Decimal Odds, also referred to as European Odds, are used in most European countries and are the default option of many Asian bookies as well. This is the easiest odds format to understand as the odds represent how much a 1 unit wager returns. For example a €1 wager at odds 1.91 returns €1.91. This return includes both your stake plus profit; to calculate how much your return will be simply multiple your stake by the given odds.

Fractional Odds – Fractional Odds are used in the UK and Ireland. Here the first number is the amount to be won, and the second number is the stake. So for examples 4/1 is stake 1 to win 4, and 10/11 is stake 11 to win 10. To calculate how much a winning bet will profit, convert the fraction to a decimal and multiply it by the stake. For example 3/2=1.5, so, if wagering at 3/2 a successful bet will return 1.5 times your stake in winnings and will also return your stake.
Implied Probability – Implied Probability is how often a bet must win to average break even. This is calculated as risk/return, so for example +200 in American format (3.00 European) is risk $100 to win $200 so a winning wager returns $300 ($100 stake + $200 win). Therefore the implied probability of +200 is $100/$300= 0.3333, which is 33.33%. For this reason you should only wager at +200 if you think the probability of winning is greater than 33.33%.
