Betting Calculator
A betting calculator converts your stake and offered odds into potential profit and total return. Enter the price exactly as the sportsbook displays it, choose the matching format, and add your stake. The result shows what you earn if the bet wins; it does not estimate the probability that the wager succeeds.

A single bet calculator shows your potential profit and total return for one wager. Enter your odds (American or decimal) and stake to see the numbers instantly—no mental math required.
Useful for any bet type (spread, moneyline, or total). Get your payout before you place the bet.
Single Bet Calculator
Worked example: $100 at -110 and at +150
Negative American odds tell you how much to stake to win $100; positive odds tell you how much a $100 stake wins. The calculator turns both into decimal odds first. -110 becomes 1 + 100 ÷ 110 = 1.9091, so a $100 bet at -110 returns $190.91 if it wins: $90.91 of profit plus the $100 you staked. To win exactly $100 at -110 you stake $110 and get $210 back.
+150 becomes 1 + 150 ÷ 100 = 2.50. A $100 bet at +150 wins $150 and returns $250. Work backwards from a target and the same rule applies: at +250 (decimal 3.50), a $40 stake wins $100 and returns $140.
What a better price is worth over 100 bets
The calculator makes small price differences visible. $100 at -105 wins $95.24 instead of $90.91 at -110, which is $4.33 more on every winner. It also lowers the win rate you need: -105 breaks even at 51.22%, -110 at 52.38%.
Run a 53-47 record of $100 flat bets through both prices. At -110 the season ends +$118.18. At -105 the same 53 winners finish +$347.62, nearly three times as much from the same picks. At a 52% win rate the gap decides the sign: 100 bets at -110 expect to lose $72.73, while 100 bets at -105 expect to make $152.38. That is the case for checking the price at several books before placing any bet, and for using this calculator on each quote instead of eyeballing them.
Typing decimal odds without losing cents
Decimal odds shown on a betting slip are usually rounded. 1.91 is the common display of -110, but the exact value is 1.909090…, so $100 at 1.91 shows $91.00 of profit instead of $90.91. Nine cents does not matter on one ticket; it does when you compare two books or total up a season. Enter the price in whichever format the sportsbook shows, with as many digits as it gives you.
Another reference point for the -1xx range: $100 at -120 wins $83.33 and returns $183.33, and needs 54.55% to break even.
What the profit figure leaves out
Profit and return describe what happens if the bet wins. They say nothing about how likely that is. A +150 price pays well because it implies only a 40% chance of winning, and that figure still includes the book’s margin; a bigger payout is not a better bet unless your own estimate beats that number.
The calculation is the same for a spread, a total, or a moneyline, because only the price drives the payout; the spread or total number itself changes which side wins, not how much it pays. A push returns the stake with no profit.
Betting calculator questions
How much do I win on a $100 bet at -110?
$90.91 in profit. With the $100 stake returned, the sportsbook pays $190.91 in total.
How much do I need to bet to win $100 at -110?
$110. Negative American odds show the stake needed to win $100, so -110 means $110 risked for $100 of profit.
Is total return the same as profit?
No. Total return includes your original stake; profit is only the amount won on top of it.
Does the spread or total number change my payout?
No. The payout depends only on the price, such as -110. The spread or total decides which side wins, not how much it pays.
What happens to my payout if the bet pushes?
A push refunds the stake with zero profit, so you get back exactly what you bet.
