How to Read Odds
Understanding odds is essential for online sports betting. Let's learn it the easy way.
Decimal Odds — The Simplest
Odds × Bet Amount = Total Return
This means a ৳500 bet returns ৳900 in total — a ৳400 profit.
Implied Probability
1 ÷ Odds × 100 = estimated chance of winning. At 1.80 odds, that's about 56%. The lower the odds, the bigger the favourite.
Fractional Odds (UK)
4/1 means ৳4 profit for every ৳1 staked. Not commonly used in Bangladesh.
American Odds (Moneyline)
+180 means ৳180 profit on a ৳100 bet. -150 means you need to bet ৳150 to win ৳100.
