| American | Decimal | Fractional | Implied prob. | Payout / $100 |
|---|---|---|---|---|
| -300 | 1.33 | 1/3 | 75.0% | $133.33 |
| -200 | 1.50 | 1/2 | 66.7% | $150.00 |
| -150 | 1.67 | 2/3 | 60.0% | $166.67 |
| -110 | 1.91 | 10/11 | 52.4% | $190.91 |
| +100 | 2.00 | 1/1 | 50.0% | $200.00 |
| +150 | 2.50 | 3/2 | 40.0% | $250.00 |
| +200 | 3.00 | 2/1 | 33.3% | $300.00 |
| +300 | 4.00 | 3/1 | 25.0% | $400.00 |
| +500 | 6.00 | 5/1 | 16.7% | $600.00 |
Implied probability = 1 / decimal odds. Break-even win rate equals implied probability in a no-vig market. Actual sportsbook odds include a margin (vig/juice), so real break-even rates are slightly higher than shown.
The short answer
The calculator above takes a single bet — your odds and your stake — and shows you exactly what it pays. Enter odds in American (-110, +200), decimal (1.91, 3.00), or fractional (10/11, 2/1) format and the calculator converts everything automatically: total payout, profit, and the implied probability the sportsbook has priced into those odds.
Key takeaway: The implied probability tells you what the sportsbook thinks the true chance of winning is. If you believe the actual probability is higher than the implied probability, the bet has positive expected value. That's the foundation of value betting.
How to use the calculator
- Pick your odds format — American, decimal, or fractional. American is standard in the US (-110 means risk $110 to win $100), decimal is used internationally (1.91 means $1.91 returned per $1 staked), and fractional is traditional in the UK (10/11 means $10 profit per $11 staked).
- Enter your odds — type the number from the sportsbook.
- Set your stake — how much you're betting.
- Read the results — total payout (stake + profit), profit alone, implied probability, and break-even win rate.
How odds payouts are calculated
Every odds format encodes the same information: the ratio between your stake and your potential profit. The math is straightforward once you know the conversion:
American odds:
- Positive (+200): Profit = stake × (odds / 100). A $10 bet at +200 profits $20.
- Negative (-110): Profit = stake × (100 / |odds|). A $10 bet at -110 profits $9.09.
Decimal odds:
- Total payout = stake × decimal odds. A $10 bet at 1.91 returns $19.10 (profit = $9.10).
Fractional odds:
- Profit = stake × (numerator / denominator). A $10 bet at 10/11 profits $9.09.
All three formats describe the same bet — they're just different notations. For a deeper explanation of why these formats exist and how to convert between them, see our guide on how betting odds work. The odds formats lesson walks through the same material step by step.
What is implied probability?
Implied probability is the win percentage the sportsbook has priced into the odds. It's calculated as: 1 / decimal odds × 100.
At -110 (decimal 1.909), the implied probability is 52.4%. That means the sportsbook is pricing this outcome as a 52.4% chance. But since both sides of a -110 market imply 52.4%, the total is 104.8% — not 100%. That extra 4.8% is the vig (the sportsbook's margin).
The calculator shows implied probability for every bet so you can compare it against your own assessment. If you think a team has a 60% chance of winning but the odds imply only 52%, that's a value bet. Our implied probability lesson covers this concept in depth.
How is this different from the parlay calculator?
This calculator handles single bets — one selection, one stake, one payout. Our parlay calculator handles multi-leg bets where you chain two or more selections together. Use the odds payout calculator to evaluate individual bets; use the parlay calculator to see what happens when you combine them.
Common odds reference
The quick-reference table in the calculator shows payouts for the most common odds you'll encounter. A few to memorize:
- -110 (decimal 1.909): The standard vig line. $110 to win $100.
- +100 (decimal 2.00): Even money. $100 to win $100.
- -200 (decimal 1.50): Heavy favorite. $200 to win $100.
- +200 (decimal 3.00): Underdog. $100 to win $200.
