How to convert between decimal and American odds

Depending on which part of the world you are from, you are likely to be comfortable seeing odds in a certain format. With an abundance of online convertors available, have you ever wondered how you can easily convert decimal to American odds and vice versa without using a calculator? Here’s the answer.

Read about the difference between American odds and Decimals odds formats.

The most common odds formats are the Decimal and the American odds. If you have been betting with European bookmakers, you are most likely used to Decimal odds. Before diving into the nitty-gritty of how to convert Decimal into American odds, though, there is one point that we need to clarify first. 

A key difference between Decimal and American odds (also known as “money line odds” or simply “lines”) is that the US odds are quoted both in positive and negative numbers, which means that there are two formulas we need to make use of depending on whether the Decimal odds are greater or less than 2.00, resulting in positive or negative US odds respectively.

The positive figures represent the amount a player will win, if he bets 100 units of any currency. US odds of -150, for example, mean that you need to risk $150 for a net profit of $100. The negative figures, on the other hand, represent the amount you need to bet in order to make $100 of net profit. Read our article American vs. Decimal odds to learn more about how to calculate profits with different formats odds.

 

Converting from Decimal to American odds

To convert a Decimal odd of 2.00 or greater, you follow the below formula:

US odds = (Decimal – 1) x 100

To see how it works in practice, here’s is the calculation of converting the odds of 2.50 and 5.40 in US-style format.

Decimal odds = 2.50

US odds = (2.50 -1) x100 = 1,50 x 100 = +150

Decimal odds =  5.40

US odds = (5.40-1) x 100 = 4.40 x 100 = +440

 

To convert a Decimal odd of less than 2.00 in US format, you use the below formula instead:

US odds = (-100)/(Decimal -1)

Let's convert now the odds of 1.50 and 1.80 in US format:

Decimal odd = 1.50

US odds = (-100)/(1.50-1) = (-100)/0.50= -200

Decimal odd =  1.80

US odds = (-100)/(1.80-1) = (-100)/0.80= -125

Converting from American to Decimal odds

If you are exclusively familiar with American odds, here are the only two rules you will ever need to remember in order to convert any US odd into its Decimal counterpart.

For positive US odds, divide the money line by 100 and add 1.

Decimal odds = (US odds/100) +1

Let’s take +200 and +600, for example:

US odds = +200

Decimal odds = (200/100) + 1 = 2 +1 = 3.00

US odds = +600

Decimal odds = (600/100) + 1 = 6 +1 = 7.00

For negative US odds, divide 100 by the US odds disregarding the negative sign and add this value to 1.00

Decimal odds = (100/US odds) + 1

Here’s how converting the odds of  -130 and -900 into Decimal-style works: 

US odds = – 1.30

(100/130) +1 = 0.769 + 1= 1.769

 US odds = -900

 

(100/900) +1 = 0.111 + 1 = 1.111

For a quick reference to the most popular odds values in both Decimal and American format, take a look at the below table.
