How to calculate a bet payout
Your payout depends on two things: how much you stake and the odds. With American odds, a positive number (like +150) is how much profit you win on a $100 stake, and a negative number (like -150) is how much you must stake to win $100. This calculator does the math for any stake instantly, showing both your profit and your total payout.
The formulas
- Positive odds (+150): profit = stake x (odds / 100). A $100 bet at +150 wins $150 profit.
- Negative odds (-150): profit = stake x (100 / odds). A $150 bet at -150 wins $100 profit.
- Total payout: stake + profit. That is the full amount the sportsbook returns when you win.
- Implied probability: 100 / decimal odds. It is the break-even win rate the price is pricing in.
Does the payout include my stake?
Yes. Total payout is your original stake plus your profit. Most sportsbooks show the total payout (sometimes called "total return") on the bet slip, while this calculator shows you both numbers so there is no confusion: profit is what you gain, payout is what lands back in your account.
American vs decimal odds payouts
American and decimal odds are just two ways to write the same price, so the payout is identical no matter which one your sportsbook shows. American odds are built around a $100 line: +150 means $150 profit per $100 risked, while -150 means you risk $150 to win $100. Decimal odds bundle your stake and profit into a single multiplier, so payout = stake x decimal odds. A +150 line is 2.50 in decimal (a $100 bet returns $250 total), and a -150 line is 1.67 (a $100 bet returns about $167 total).
To convert by hand, a positive American price becomes decimal with (odds / 100) + 1, and a negative price becomes (100 / odds) + 1. This bet calculator accepts either format and shows your profit, total payout, and implied probability the same way, so you never have to convert in your head.

Quick reference: common odds and their $100 payouts
- +200 (decimal 3.00): $200 profit, $300 total payout. Implied win rate about 33.3%.
- +100 / even money (decimal 2.00): $100 profit, $200 total payout. Implied win rate 50%.
- -110 (decimal 1.91): about $90.91 profit, $190.91 total payout. The standard spread price, implying roughly 52.4%.
- -200 (decimal 1.50): $50 profit, $150 total payout. Implied win rate about 66.7%.
Why the price matters more than you think
The same bet at a better number pays more every single time you win. A few cents of odds looks tiny on one bet, but across a season it is the difference between a winning year and a losing one. That is why getting the best available price before you bet is one of the most reliable edges there is.

Frequently asked questions
How do you calculate a bet payout?
For positive odds, profit = stake x (odds / 100). For negative odds, profit = stake x (100 / odds). Total payout is stake plus profit.
Does the payout include your stake?

What does +150 pay on $100?
$150 profit, for a total payout of $250 (your $100 stake plus $150 winnings).
What does -150 pay on $100?
About $66.67 profit, for a total payout of roughly $166.67. Negative odds mean you risk more than you win.
What is implied probability?
The win rate the odds are pricing in (100 divided by decimal odds), which is also the break-even rate you must hit to profit.
How do I get a bigger payout on the same bet?
Bet it at a better price. Shopping books for the best odds increases your payout every time the bet wins.
