Odds Types

These are the different formats of odds used in betting. The main types are:

1. Decimal odds are the most widely used format in Europe, Canada, and Australia. They are easy to understand because they represent the total payout for every 1 unit staked.

   • Formula: Payout = Stake × Odds

   • Example:

     • Odds: 2.50 - If you bet $10: Payout = 10 × 2.50 = $25 (which includes the $10 stake and $15 profit).

2. Fractional odds are commonly used in the UK and are expressed as a fraction (e.g., 5/1, 10/3, etc.). The numerator (top number) shows how much profit you will make for every denominator (bottom number) of stake.

   • Formula: Payout = Stake × Odds + Stake

   • Example:

     • Odds: 5/1 - If you bet $10: Payout = 10 × (5/1)+10 = $60 (which includes the $10 stake and $50 profit).

3. Moneyline (American) odds are popular among the United States bookmakers. The Moneyline odds show how much you need to bet to win $100 (if Moneyline is negative) or how much you would earn if your stake were $100 (if Moneyline is positive).

   • Formula:

     • Positive Odds: Show how much profit you would make from a 100-unit stake. Payout = Stake × Odds/100 + Stake

     • Negative Odds: Show how much you need to stake to make 100 units of profit. Payout = - Stake/Odds × 100 + Stake

   • Examples:

     • Odds: +200 - If you bet $50: Payout = 50 × (200/100)+50= $150 (which includes the $50 stake and $100 profit).

     • Odds: -150 - If you bet $50: Payout = -50/(-150) × 100 + 50 = $83.33(your $50 stake + $33.33 profit).

4. Hong Kong odds (or HK) odds are standard among the bookmakers in China. They are similar to fractional odds, except written not in a fractional but decimal form instead.

   • Formula: Payout = Stake × Odds + Stake

   • Example:

     • Odds: 1.50 - If you bet $10: Payout = 10 × 1.50 + 10 = $25 (which includes the $10 stake and $15 profit).

5. Indonesian odds are popular among bookmakers available in Indonesia. Positive odds work similarly to Hong Kong odds, negative odds represent how much you need to stake to win 1 unit in profit. These betting odds are quoted as a number with absolute value greater (or equal) than 1.

   • Formula:

     • Positive Odds (x>=1 → decimal odds >=2): Payout = Stake × Odds + Stake

     • Negative Odds (x<=-1 → decimal odds between 1 and 2): Payout = - Stake/Odds + Stake

   • Examples:

     • Odds: +1.50 - If you bet $10: Payout = 10 × 1.50 + 10 = $25 ($15 profit and $10 stake).

     • Odds: -1.50 - If you stake $10: Payout = -10/(-1.50) + 10 = $16.67(which includes $10 stake and $6.67 profit)

6. Malay odds are similar to Indonesian odds and are commonly used in Malaysia and Singapore. These betting odds are quoted as a number with absolute value no greater than 1 (or equal).

   • Formula:

     • Positive Odds (0<x<=1 → decimal odds between 1 and 2): Payout = Stake × Odds + Stake

     • Negative Odds (-1<=x<0 → decimal odds >=2): Payout = - Stake /Odds + Stake

   • Examples:

     • Odds: +0.50 - If you bet $10: Payout = 10 × 0.50 + 10 = $15 ($5 profit and $10 stake).

     • Odds: -0.50 - If you bet $10: Payout = -10 /(-0.50) + 10 = $30 ($10 stake and 20$ profit).
