Football odds represent the probability of an event and your potential profit. Globally, there are three common formats:

Popular in the United States, American odds use a plus (+) or minus (-) sign:
- Plus sign (+) shows how much profit you’d earn from a $100 bet. For example, +200 means a $100 bet returns $200 profit.
- Minus sign (-) shows how much you must wager to win $100. For instance, -150 means you bet $150 to win $100.
These odds also imply the likelihood of an outcome. For example:
91ph- -130 implies a 56.5% chance of winning
- +110 implies a 47.6% chance of winning

Decimal Odds
Widely used in Europe, Canada, and Australia, decimal odds are easy to understand and calculate:
- They represent the total return (stake + profit) per $1 wagered.
- For example, odds of 2.50 mean a $10 bet returns $25 (10 x 2.50).
- Lower numbers indicate favorites, higher numbers underdogs.
Fractional Odds
These are traditional in the UK and Ireland and displayed as fractions, like 5/1 or 2/1:
- 5/1 means for every $1 staked, you earn $5 profit.
- 2/1 means you get $2 profit per $1 staked.
- Total return is calculated by: stake x fraction = profit + stake.

Types of Football Bets
To fully utilize your knowledge of odds, you must understand the different types of football bets available.
Moneyline Bets
Bet directly on the winner. Simple and straightforward. If the odds are -150 for Team A and +130 for Team B:
- Team A is favored; you must bet $150 to win $100.
- Team B is the underdog; a $100 bet wins you $130.
Spread Betting
This form involves betting on the margin of victory:
- Example: Patriots -6.5 vs Jets +6.5
- Patriots must win by more than 6.5 points for you to win your bet.
- If Jets lose by less than 6.5 or win outright, Jets bettors win.
Over/Under (Totals)
Bet on whether the total combined score will be over or under a set number:
- If the line is 45.5 and the score is 24-21 (45 total), “Under” wins.
- If the score is 28-20 (48 total), “Over” wins.
How to Convert Odds to Implied Probability

One of the smartest ways to assess betting value is to convert odds into implied probability. This helps determine if a bet is worth taking based on your own prediction.
Formulas:
- American Odds (positive): 100 / (odds + 100) x 100
- American Odds (negative): odds / (odds + 100) x 100
- Decimal Odds: 1 / decimal odds x 100
- Fractional Odds: denominator / (numerator + denominator) x 100
Example: Decimal odds of 2.50 implies a 40% chance of winning (1 ÷ 2.50 × 100).
Comparison Table: Odds Formats
| Odds Format | Example | Implied Probability | Payout on $100 |
|---|---|---|---|
| American | -150 | 60% | $66.67 profit |
| American | +200 | 33.3% | $200 profit |
| Decimal | 2.50 | 40% | $150 profit |
| Fractional | 3/1 | 25% | $300 profit |
