Hey there, sports betting fans! If you’ve ever placed a bet—especially on cricket—you’ve probably noticed that odds come in different styles. Sometimes they’re fractions, decimals, and sometimes those mysterious American numbers. It can feel overwhelming, but don’t worry! That’s where odds conversion comes in to save the day.
In this guide, we’ll walk you through how to convert fractional odds into decimal and American formats, step by step. Why focus on fractional odds? They’re super common, especially in the UK, and knowing how to switch them around can make betting easier and more fun. Whether you’re a newbie or a pro, understanding various types of betting odds formats can help you spot better deals and make smarter choices.

Understanding Fractional Odds
Fractional odds are like the old-school way of showing odds, and you’ll see them a lot if you’re betting from the UK. They look like fractions—think 5/1 or 3/2—and they tell you how much profit you’ll make compared to your bet.
For example, imagine you’re betting on a cricket match, and Team A has odds of 4/1. That means for every INR 1 you bet, you’ll win INR 4 in profit if they win. So, if you put down INR 10, you’d get INR 40 profit plus your INR 10 back—INR 50 total.
But here’s the twist: fractional odds can also be less than 1, like 1/3. If you bet INR 10 at 1/3 odds, you’d win INR 3.33 profit plus your INR 10, making it INR 13.33 total. It’s a smaller win, but it shows the team’s more likely to succeed.
Getting a grip on fractional odds is key because they’re one of the main betting odds types out there, and you’ll run into them on lots of betting sites.
Understanding Decimal Odds
Now, let’s talk decimal odds. These are popular in places like Europe, Canada, and Australia because they’re so easy to understand. Unlike fractional odds, which focus on profit, decimal odds show your total payout, including your original bet.
Say a cricket team has decimal odds of 3.00. If you bet INR 1, you’ll get INR 3 back if they win—that’s INR 2 profit plus your INR 1 stake. Or, if you bet INR 10 at odds of 2.75, your payout would be INR 10 × 2.75 = INR 27.50. Subtract your INR 10, and your profit is INR 17.50.
Decimal odds are awesome because they’re simple to multiply and compare. They’re a big deal on many betting platforms, so knowing this betting odds type is a must.
Understanding American (Moneyline) Odds
American odds—sometimes called moneyline odds—can seem a little weird at first. They’re big in the US and come as positive or negative numbers.
Positive odds (like +300) tell you how much profit you’d make on an INR 100 bet. So, +300 means an INR 100 bet wins you INR 300 profit, plus your INR 100 back—INR 400 total.
Negative odds (like 200) show how much you need to bet to win INR 100 profit. At -200, you’d bet INR 200 to win INR 100 profit, plus your INR 200, for INR 300 total.
Picture this: a cricket team’s at +150. Bet INR 50, and you’d win INR 75 profit (50 × 150 / 100), plus your INR 50—INR 125 total. But if they’re at -120, you’d bet INR 120 to win INR 100 profit, plus your stake.
They take some getting used to, but American odds are just another way to look at betting odds types.
Step-by-Step Guide to Converting Fractional Odds to Decimal Odds
Ready to start converting? Turning fractional odds into decimal odds is a breeze with this formula:
Decimal Odds = (Numerator / Denominator) + 1
Let’s try it out. Say you’ve got fractional odds of 7/2.
Divide the numerator (7) by the denominator (2): 7 ÷ 2 = 3.5
Add 1: 3.5 + 1 = 4.5
Your decimal odds are 4.50. Easy, right?
Here’s another: fractional odds of 1/5.
1 ÷ 5 = 0.2
0.2 + 1 = 1.2
So, that’s 1.20 in decimal odds.
Why bother with odds conversion? Well, if a site shows decimal odds but you’re used to fractions, this trick helps you figure out your payout fast. It’s especially handy on platforms like BetPost, where decimal odds might pop up.
Step-by-Step Guide to Converting Fractional Odds to American Odds
Now, let’s tackle American odds. The method changes depending on whether your fractional odds are above or below 1.
For fractional odds greater than or equal to 1 (like 5/1 or 1/1):
These usually mean an underdog or even a chance, and you’ll get positive American odds.
Formula: American Odds = (Numerator / Denominator) × 100
Example: Fractional odds of 5/1.
5 ÷ 1 = 5
5 × 100 = 500
American Odds: +500
That’s an INR 500 profit on an INR 100 bet.
For fractional odds less than 1 (like 2/5):
These mean a favorite, so the American odds are negative.
Formula: American Odds = – (Denominator / Numerator) × 100
Example: Fractional odds of 2/5.
5 ÷ 2 = 2.5
-2.5 × 100 = -250
American Odds: -250
You’d need to bet INR 250 to win INR 100 profit.
This odds conversion skill is gold if you’re flipping between formats on different sites. It helps you see the risk and reward clearly.
