Here is a step by step guide on how to convert the different odds types:

Decimal to Fractional conversion:

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.

Stake + profit = payout

The first thing to understand is the difference between payout and profit. When you put a bet on you give your stake to the sportsbook. If you win the sportsbook will give you your stake back and pay you your profit. You can’t count getting your stake back as profit because it was yours to begin with.

If you bet 1 m฿ at even money and the bet wins

Decimal odds

Decimal odds are the most common odds format in the modern era. Decimal odds are great because they are simple and let you do calculations easily. Think of it like the metric system, it is superior but some old timers and Americans stubbornly refuse to use it.

The odds will be your payout for every unit you stake. If the odds are 1.32 you will get back 1.32 m฿ for every 1 m฿ you stake. This payout includes your stake of 1 m฿ and profit of 0.32 m฿. Here are a couple of examples with winning bets.

Odds of 2.00 are “even money” because if you bet 1 m฿ you will either lose 1 m฿ or win 1 m฿.

The two other main odds formats are inferior and less common than decimal odds; they are fractional odds and American odds. These odds types are outdated and sportsbooks that show one of these odds types will also have the option to displaying decimal odds instead.

Fractional odds

Fractional odds are expressed as two numbers with a / in between like a fraction. Think of it as profit/stake. The first number is the amount you will profit if you stake the second number. This could also be expressed as the second number is the amount you would need to stake to profit the first number.

Add both numbers together to see the payout you would get by staking the second number.

For example fractional odds of 4/6 means you would win 4 m฿ by staking 6 m฿. So if you stake 6 m฿ and win, your payout will be 10 m฿. This is made up of your 6 m฿ stake and 4 m฿ profit.

American Odds To Decimal

Even money would be written as 1/1 but instead is called “evens”.

American odds

American odds are either expressed as a negative (-) number or a positive (+) number.

Negative (-) numbers are used for bets of less than even money, such as a favorite to win. A negative (-) number is how much you would have to stake to profit 100 units. Odds of -220 means you would have to stake 220 m฿ to win 100 m฿. So if you staked 220 m฿ and won, your payout would be 320 m฿, made up of your 220 m฿ stake and 100 m฿ profit.

Positive (+) numbers are used for bets at greater than even money such as for an underdog. Positive (+) numbers are how much you will profit if you stake 100 units. Odds of +480 means that if you stake 100 m฿ and win, you will profit 480 m฿. So your payout would be 580 m฿ made up of your 100 stake and 480 m฿ profit.

Even money could be written as +100 or -100.
