Fractional Odds
Fractional odds show win rates, used a lot in UK bet places. A 5/1 fraction means you get back $500 on a $100 bet. These odds make it clear how much can be made but you need to do more math to know all returns.

- Lakers at -200: Have to bet $200 to win $100 (liked more)
- Nets at +150: $100 bet brings back $150 (liked less)
Market Moves and Odds Shifts
Betting odds keep changing based on:

These parts make odds that show both what can likely happen and active market doings, giving bettors chances to find good bets across different markets.
Knowing Different Betting Odds
American Odds
American odds, also known as moneyline odds, work with a plus/minus way. With odds of -150, bettors must put down $150 to win $100. On the other hand, +150 odds mean a $100 bet makes $150 in profit. This kind is big in North American sports bet markets, mainly in NFL, NBA, and MLB bets.
Decimal Odds
Decimal odds show the total money you can get for each unit bet, including the first bet money. For example, 2.50 decimal odds mean a full pay of $2.50 for each $1 bet. This form is big across European and Australian bet markets, offering easy maths for possible money back. Decimal odds make it simple to size up chance and how much you could get for both new and old bettors.
Fractional Odds
Fractional odds show as rates, like 5/1 or 9/2, showing possible profit by your bet. With 5/1 odds, a right $1 bet brings back $5 in profit plus the first bet. These odds are still all over in UK horse racing and old British bet-making. Though they first look hard, fractional odds give clear ideas of what returns could be in racing and special bet markets.
