🎰 Understanding Betting Odds

In this section, we’ll be looking closely at the common types of bettings odds and how to convert them to other betting odds.

✅ American Odds

The American odds are also called Moneyline or US odds. They are commonly used by the US sports bettors. American odds are represented by positive or negative symbols.

  • The positive symbol indicates the amount you would win on a $100 bet.
  • The negative symbol indicates the amount that must be bet to win $100.

American Odds Conversion

Here’s a guide on how to convert American odds to other types of odds.

American odds to Fractional odds

  • Positive American odds: American / 100 = Fractional odds
  • Negative American odds: -100 / -American odds = Fractional odds

American odds to Decimal odds

  • Positive American odds: (American Odds / 100) + 1 = Decimal odds
  • Negative American odds: 1 – (100 / – American odds) = Decimal odds

✅ Decimal Odds

Decimal odds are also known as European odds. They are commonly used by European sport bettors but are also used in other countries.

The formula for decimal odds is simply:

Bet amount multiplied by odds = return

Overall return = (Profit – Initial bet)

Let’s take a look at an example:

You made a bet $10 and the decimal odds is 4.00.

  • So, $10 * 4.00 = $40
  • Overall return is $40 – $10 = $30

Therefore, your overall return is $30 because the initial $10 was risked.

Decimal Odds Conversion

Here’s how to convert Decimal odds to other betting odds:

Decimal odds to American odds

  • Positive American odds: (Decimal odds – 1) * 100 = American odds
  • Negative American odds: -100 / (Decimal odds – 1) = American odds

Decimal odds to Fractional Odds

  • Decimal odds / 1 – 1 = Fractional odds

✅ Fractional Odds

Fractional odds are mostly used in the UK. As the name implies, it is expressed in fractions. For example, 7/2. It is much better to say 7/2 than 3.5/1.

The odds of 7/2 is read out as “7 to 2”. 2 represents the wager amount and 7 represents the amount a bettor is likely to win.

The odds off 7/2 will pay out 3.5 times the initial bet. For example, a $50 would then pay out $175 in profit.

Fractional Odds Conversion

Here’s how you would convert fractional odds to American and decimal odds:

Fractional odds to American odds

  • Positive American odds: Fractional odds * 100 = American odds
  • Negative American odds: -100 / Fractional odds = American odds

Fractional odds to Decimal odds

  • Fractional odds + 1 = Decimal odds

✅ Implied Probability

Fractional, Decimal and American odds can be converted into Implied Probablility, expressed in percentage.

For example, a bet made at -400 American odds (1.25 decimal odds and ¼ fractional odds) has 80% implied probability of winning.
