The short answer
In American odds, +200 means a $100 bet wins $200 in profit. If your bet wins, you get $300 back in total: your original $100 stake plus the $200 you won.
The plus sign (+) marks the underdog — the side the sportsbook considers less likely to win. The number tells you how much profit a $100 stake returns.
+200 payouts at any stake
You do not have to bet exactly $100. The math scales proportionally: at +200 you always win double your stake in profit. Example payouts:
| Your stake | Profit if it wins | Total returned |
|---|---|---|
| $10 | $20 | $30 |
| $25 | $50 | $75 |
| $50 | $100 | $150 |
| $100 | $200 | $300 |
| $200 | $400 | $600 |
The formula: profit = stake × (200 ÷ 100). Check any stake and price instantly with the sports betting calculator.
The 33.3% implied probability
What the sportsbook thinks +200 means.
Odds of +200 carry an implied win probability of 33.3%. The formula for positive odds is 100 ÷ (odds + 100), so 100 ÷ 300 = 33.3%.
That is the break-even point: if you believe the true chance of winning is higher than 33.3%, the price may offer value. If it is lower, the price is against you. Comparing a model's probability against the implied probability is exactly how AI Model Edges flags games.
+200 in other odds formats
The same price, written three ways.
- Fractional: 2/1. You win $2 for every $1 staked, plus your stake back.
- Decimal: 3.00. Your total return per $1 staked, including the stake. Multiply your stake by 3.00 for the full payout.
- American: +200. Profit on a $100 stake.
All three describe the identical price. For the full conversion system, see Betting Odds Explained.
+200 vs -200: the other side of the line
Plus is the underdog, minus is the favorite.
When one side is +200, the other side is usually a minus price such as -240. A minus number tells you how much you must risk to win $100: at -200 you risk $200 to win $100 in profit ($300 total back).
The gap between the two prices is the sportsbook's margin. That margin is why at standard -110 odds you need to win 52.38% of your bets just to break even.
Risks to keep in mind
Underdog prices are tempting for a reason.
- A +200 underdog loses about two times out of three at fair odds — long losing streaks are normal.
- Bigger payouts do not mean better bets; value comes from the price versus the true probability, not the size of the win.
- Keep stakes small and consistent with the Bankroll Management Calculator.
