convert fractional odds to decimal

While fractional odds are common in the UK, decimal odds are widely used internationally due to their simplicity in interpretation. Let’s look at how you can convert fractional odds to decimal odds.

Understanding Fractional Odds

Fractional odds, typically used in the UK, represent the profit you stand to gain relative to your stake. They are expressed as a fraction – for example, 5/3. This means for every 3 units you bet, you would win 5 units if your bet is successful.

How to Convert Fractional Odds to Decimal?


Decimal Odds = (Numerator of the Fraction) / (Denominator of the Fraction) + 1

In other words, divide the numerator by the denominator and add 1.

Step-by-Step Conversion from Fractional Odds to Decimal

Let’s say the odds are 5/3.

So, decimal odds = 5 (Numerator) / 3 (Denominator) + 1

Decimal Odds = 5/3 + 1 = 1.67 + 1 = 2.67
