How To Use This Calculator
Enter your stake and the odds in any format. The calculator shows your total payout, net profit, and the implied probability so you can decide whether the price offers value before placing the bet.
Type the amount you plan to wager. Default is $100 but any number works.
Pick the format (American, decimal, fractional, etc.) and enter the value from your sportsbook.
Total payout includes your stake. Profit is what you actually win. Implied probability shows the breakeven win rate.
How to Calculate Sports Betting Payouts
The math depends on the odds format. Here are the formulas for the three most common formats.
Decimal odds: Payout = Stake x Odds. A $100 bet at 2.50 returns $250 ($150 profit + $100 stake).
American positive (+150): Profit = Stake x (Odds / 100). A $100 bet at +150 profits $150 for a $250 total payout.
American negative (-200): Profit = Stake / (Odds / 100). A $200 bet at -200 profits $100 for a $300 total payout.
Fractional (3/2): Profit = Stake x (Numerator / Denominator). A $100 bet at 3/2 profits $150 for a $250 total payout.

Implied Probability and What It Means
Every set of odds maps to a breakeven win rate. If the true probability of the outcome is higher than the implied probability, the bet has positive expected value. If lower, the bet is a long-term loser. The calculator shows implied probability automatically.
Standard pricing on US spreads and totals. You need to win more than 52.4% to profit long-term.
Moderate underdog. You need a true win rate above 40% for the bet to be profitable.
Larger underdog. Higher payout per dollar but the bet must hit at least 28.6% of the time to break even.
Big longshot. The price assumes the outcome wins at most 16.7% of the time.
Common Mistakes to Avoid
Total payout includes your original stake. Profit is what you actually win. A $100 bet at +150 has a $250 payout but only $150 of profit.
+150 and -150 produce very different payouts. +150 profits $150 on a $100 stake. -150 requires $150 staked to profit $100. The sign flips everything.
Sportsbook odds include a margin called vig. The implied probabilities sum to more than 100%, so the true probabilities are slightly lower than the odds suggest. Use our No-Vig Calculator to find the fair price before evaluating a payout.
Decimal 2.50 is not the same number as fractional 2/5. Always convert to a single format before comparing prices across books. Use our Odds Converter to switch between formats instantly.
Frequently Asked Questions
How do you calculate a sports betting payout?
Multiply your stake by the decimal odds to get total payout. Profit equals payout minus stake. For American odds: positive (+150) profit equals stake times odds divided by 100; negative (-200) profit equals stake divided by odds divided by 100. The calculator above does this automatically.
What does -110 pay on a $100 bet?
A -110 bet pays $90.91 in profit on a $100 stake, for a total $190.91 payout. This is the standard line at US sportsbooks for spreads and totals. The implied probability is about 52.4 percent.
How much do I win on a $100 bet at +150?
A $100 bet at +150 returns $250 total ($100 stake plus $150 profit). The implied probability is 40 percent. In decimal odds +150 equals 2.50.
What does -200 mean for my payout?
At -200 you must stake $200 to win $100 in profit, for a $300 total payout. The implied probability is 66.7 percent. Strong favorites pay less per dollar staked.
What is the difference between payout and profit?
Payout is the total amount returned, including your original stake. Profit is what you actually earn. A $100 bet at +150 has a $250 payout but only $150 of profit.
How do I calculate payout from decimal odds?
Multiply your stake by the decimal odds. A $50 bet at 2.40 returns $120 total ($50 times 2.40). Profit is $70. Decimal odds always include the stake in the multiplier.
How do I calculate payout from fractional odds?
Multiply your stake by the fraction to get profit, then add the stake for total payout. A $20 bet at 5/2 produces $50 profit ($20 times 5 divided by 2) plus the $20 stake, for $70 total.
What is implied probability?
Implied probability is the breakeven win rate at given odds. At +150 the implied probability is 40 percent, meaning the bet is profitable only if your true win rate is above 40 percent.
What does +500 pay?
A +500 bet pays $500 profit per $100 staked, for $600 total. The implied probability is roughly 16.7 percent. Large underdogs offer big payouts but win infrequently at most US books.
Are betting payouts taxed in the US?
Yes. Sports betting profit is taxable as ordinary income. Sportsbooks issue a W-2G for single wins of $600 or more at 300:1 odds or higher. Track every payout for accurate year-end reporting.
Pro Tip: Pair Payout with Expected Value
Knowing the payout is only half the picture. To know whether a bet is actually a good price, compare the implied probability to your estimated true probability. Use our Expected Value Calculator to find +EV bets before you stake them.
