To work out a payout, convert the odds to decimal and multiply by your stake; subtract the stake to get your profit. A $100 bet at +150 returns $250.00 ($150.00 profit), and a $100 bet at -110 returns $190.91 ($90.91 profit).
How to use it: enter your odds (American, decimal, fractional or percent) and your stake in the calculator below; it returns your profit, total payout and implied probability. The payout chart further down covers common prices.
Quick Answer
An odds payout calculator turns a stake and a sportsbook price into two numbers: net gain and total return. A $100 bet at +150 wins $150 net and returns $250 total. A $100 bet at -150 wins about $66.67 net and returns about $166.67 total. The payout is useful, but PropsBot also connects that math with odds shopping, implied probability, EV, and bet tracking.
Payout math looks simple until a bettor starts comparing American odds, decimal odds, fractional odds, parlays, futures, and player props on the same card. The same $50 stake can mean very different things at +110, +145, -120, 2.40 decimal, or 20/1 fractional. This page gives the quick math and the better workflow: calculate the payout, compare the price, then decide whether the wager still deserves a spot in the account.
What The Calculator Should Show
- Stake: the amount risked on the bet.
- Odds: the sportsbook price in American, decimal, or fractional format.
- Net gain: the amount won beyond the original stake.
- Total return: net gain plus the original stake.
- Break-even probability: how often that price must win before it becomes neutral.
The two payout numbers are easy to mix up. Net gain is the actual win amount. Total return is what comes back to the account if the wager cashes. A $100 bet at even money does not “win $200.” It wins $100 and returns $200 total. Keeping that distinction straight matters when tracking results across props, parlays, and futures.
American Odds Payout Formula
Positive American odds show the net gain on a $100 stake. Negative American odds show how much must be risked to win $100. The formulas are:
- Positive odds: net gain = stake x odds / 100.
- Negative odds: net gain = stake x 100 / absolute odds.
- Total return = stake + net gain.
For example, $80 at +175 wins $140 net and returns $220 total. The same $80 at -125 wins $64 net and returns $144 total. Both wagers use the same stake, but the price changes the payout and the break-even point.
Common Payout Examples
| Stake | Odds | Net Gain | Total Return |
|---|---|---|---|
| $25 | +120 | $30.00 | $55.00 |
| $50 | +150 | $75.00 | $125.00 |
| $100 | -110 | $90.91 | $190.91 |
| $100 | -150 | $66.67 | $166.67 |
| $100 | +250 | $250.00 | $350.00 |
These examples are not picks. They are reference math. A bigger payout does not mean a better wager. It usually means the sportsbook is pricing a lower-probability outcome. That is why payout, probability, and line shopping belong in the same workflow.
Decimal And Fractional Odds
Decimal odds make total return easy: stake x decimal odds. A $50 bet at 2.50 decimal returns $125 total, which is $75 net gain. To find net gain directly, subtract 1 from the decimal price and multiply by the stake.
Fractional odds show the win amount relative to stake. At 5/1, every $1 staked wins $5 net. At 20/1, every $1 staked wins $20 net. A $25 wager at 20/1 wins $500 net and returns $525 total.
Why Odds Shopping Changes The Result
Payout calculators are only as good as the price entered. A $100 wager at +110 wins $110 net. The same wager at +125 wins $125 net. Nothing changed about the player, matchup, or market. The difference is simply the sportsbook price.
PropsBot keeps payout math close to sports betting odds shopping because better prices can change a break-even number before the bet is even placed. A bettor comparing the same player prop across books may find one sportsbook at -115 and another at +105. The payout and break-even rate move immediately.
When To Use This Page
Use this page when the first question is “what does this bet pay?” Use the betting payout calculator for general payout math, the betting odds calculator for odds format and return examples, the betting odds converter for price formats, and the implied probability calculator to connect payout with break-even rate.
The clean process is calculate, compare, convert, then decide. Payout tells you the return. Odds shopping tells you whether a better number is available. Implied probability tells you what the price demands. The model or projection tells you whether the bet has enough edge to consider.
PropsBot Workflow
PropsBot is built around the part of betting most people skip: tracking the decision behind the wager. A payout can look attractive on a longshot and still be a bad price. A smaller payout on a prop can be more interesting if the model projection is stronger than the market price. The goal is not to chase the largest return on the screen. The goal is to compare payout, probability, price quality, and stake size before the ticket is placed.
One practical habit helps: write down the number used for the calculation before the bet is placed. If the market moves later, the original payout and the closing price tell a useful story about whether the process found a good number or simply landed on the right side of one result.
The payout formula in plain words
- Positive American odds (+150): profit = stake x odds / 100. $100 at +150 profits $150.00.
- Negative American odds (-110): profit = stake x 100 / the odds without the minus sign. $100 at -110 profits $90.91.
- Decimal odds (2.50): total return = stake x decimal odds; profit = total return minus the stake.
- Fractional odds (5/2): profit = stake x the fraction. $10 at 5/2 profits $25.00.
- Total return = profit + stake. It is what comes back to your account when the bet wins.
Worked payout examples
- $50 at +135 (American underdog): 50 x 135 / 100 = $67.50 profit; total return $117.50. Implied probability 42.6%.
- $40 at -125 (American favorite): 40 x 100 / 125 = $32.00 profit; total return $72.00. Implied probability 55.6%.
- $25 at 3.40 (decimal): 25 x 3.40 = $85.00 total return, so $60.00 profit. That is +240 in American odds and 29.4% implied.
- $20 at 7/2 (fractional): 20 x 7/2 = $70.00 profit; total return $90.00 (decimal 4.50, American +350, 22.2% implied).
Odds payout chart: what $10 and $100 bets pay
Profit excludes the stake; total return includes it. Decimal odds are rounded to three places, probabilities to one decimal place and money to the cent; every figure is calculated from the unrounded prices.

Common payout mistakes
- Reading total return as profit. At -110 a $100 bet returns $190.91 but only $90.91 of that is profit.
- Treating -150 like +150. The minus sign means you risk more than you can win: $100 at -150 profits $66.67, while $100 at +150 profits $150.00.
- Rounding -110 to 1.91. The exact decimal is 1.9091. On a single $100 bet that rounding adds $0.09 to the payout; across a parlay the gap grows with every leg.
- Expecting a bonus bet to return its stake. Many sportsbooks pay only the profit on bonus bets; check your book’s terms.
- Chasing the biggest payout. A bigger payout means a less likely outcome. Compare the price’s implied probability with your own estimate using the implied probability calculator.
Odds payout calculator FAQ
How do you calculate a betting payout?
Convert the odds to decimal (positive American odds: 1 + odds / 100; negative American odds: 1 + 100 / the odds without the minus sign), multiply by your stake for the total return, then subtract the stake for profit.
How much does a $100 bet at -110 pay?
$90.91 profit and $190.91 total return, because -110 is 1.9091 in decimal odds.
What does a $10 bet at +200 pay?
$20.00 profit and $30.00 total return. +200 means $200 profit per $100 staked.
Is the payout the same as the profit?
No. The payout (total return) includes your stake; the profit does not. $100 at +150 has a $250.00 payout and $150.00 profit.
How do bonus bets pay out?
At many sportsbooks a bonus bet returns only the profit, not the bonus stake, so a $10 bonus bet at +200 pays $20.00 instead of $30.00. Bonus terms vary by sportsbook, so check yours.
