American Odds are the standard in the US and are based on a $100 baseline. If the odds are +110, you win $110 in profit on a $100 bet (totaling $210). If the odds are -110, you win $90 in profit on a $100 bet (totaling $190). To profit exactly $100, you must bet the amount shown after the negative sign—meaning for odds like -133, -200, or -345, you would need to wager $133, $200, or $345 respectively to win $100.
Decimal Odds are popular worldwide and represent the total payout for every $1 wagered. For example, odds of 1.30 pay out $13 on a $10 bet. Odds of 3.90 pay out $39 on a $10 bet.
Fractional Odds can seem tricky but are actually quite simple. The second (bottom) number is your stake, and the first (top) number is your potential profit. A 7/2 bet means you profit $7 for every $2 wagered (or $3.50 for every $1).
