If I Bet $100, How Much Do I Win?
Bet $100 at +150 and you win $150. Bet $100 at -150 and you win $66.67. Same stake, very different payouts, because the number next to your pick is not a suggestion. It is a formula. Once you know the two formulas behind American odds, you can read any line and know exactly what a $100 bet pays before you tap confirm.
This guide stays concrete. I will run the math for plus and minus odds, hand you a reference list of $100 payouts you can scan in seconds, explain why your stake comes back on top of your profit, and show how parlay payouts stack. Want a refresher on the notation first? Our breakdown of what -110 means in betting covers it in depth.
article Summary
A $100 bet at -110 wins $90.91 in profit and returns $190.91 total. A $100 bet at +200 wins $200 in profit and returns $300 total. For positive odds, profit equals $100 times the odds divided by 100. For negative odds, profit equals $100 divided by the odds divided by 100. Your original stake is always returned on top of the profit when the bet wins.
The Two Formulas Behind Every $100 Payout
American odds come in two flavors, positive and negative, and each carries its own payout formula. Neither needs a calculator once you have run them a few times. My first move when a newer bettor asks how much a wager pays is to show them these two lines of math, because between them they cover every straight bet on the board.
Positive Odds (+150, +200, +300)
Positive odds show your profit on a $100 stake directly. The formula is profit equals stake times odds divided by 100. A $100 bet at +150 works out to $100 times 1.5, which is $150 in profit. A $100 bet at +200 is $100 times 2, or $200 in profit. The plus number after the sign is quite literally what $100 wins, so +300 pays $300 and +500 pays $500 on a $100 wager.
Negative Odds (-110, -150, -200)
Negative odds tell you how much you must stake to win $100, so the payout on a flat $100 bet is smaller. The formula is profit equals stake divided by the odds divided by 100. A $100 bet at -150 is $100 divided by 1.5, which is $66.67 in profit. A $100 bet at -200 is $100 divided by 2, or $50 in profit. The bigger the favorite, the less each $100 returns, which is why heavy chalk at -400 or -500 pays so little for the risk.
What a $100 Bet Pays at Every Common Odds Level
Here is the reference set I keep in my head for the lines that show up most often. Each entry lists the profit on a $100 bet and the total return, which is your profit plus the $100 stake you get back on a winner.
+100 (even money): wins $100 profit, returns $200 total.
+110: wins $110 profit, returns $210 total.
+150: wins $150 profit, returns $250 total.
+200: wins $200 profit, returns $300 total.
+250: wins $250 profit, returns $350 total.
+300: wins $300 profit, returns $400 total.
-110 (standard vig): wins $90.91 profit, returns $190.91 total.
-120: wins $83.33 profit, returns $183.33 total.
-150: wins $66.67 profit, returns $166.67 total.
-200: wins $50 profit, returns $150 total.
-250: wins $40 profit, returns $140 total.
The pattern reads cleanly once it is in front of you. Underdogs at plus odds pay more than your stake, even money at +100 doubles your money, and favorites at minus odds pay less than the $100 you put up. For the full logic behind reading each price, our guide to reading betting odds lays out the formats side by side.
Payout vs Profit: Why Your Stake Comes Back
The word "payout" trips people up because sportsbooks and bettors sometimes use it for two different numbers. Profit is what you win on top of your bet. Total return, which most apps label as the payout, is your profit plus the original stake handed back to you. A winning $100 bet at +150 shows a payout of $250 on the slip, but only $150 of that is new money. The other $100 was always yours.
This distinction matters when you compare bets. A $100 winner at -200 returns $150 total, so the payout figure looks healthy, yet the actual profit is only $50. I always read the profit line rather than the total return when I judge whether a price is worth taking, because the return number quietly includes cash I already put up. On a losing bet you get neither the profit nor the stake, so the true cost of a $100 wager is the full $100 at risk, not the smaller profit figure. Break-even math runs on the profit number too. At -110 you have to hit about 52.4 percent of your bets just to stay even, because you are risking $110 of value to win $100 of it back each time.
The Same Payout in Decimal and Fractional Odds
American odds are the default in the United States, but decimal and fractional formats show up on international books, in horse racing, and inside some betting tools. They describe the identical payout with different math. If you would rather skip the conversion, our odds converter flips any price between the three formats for you. To see how they line up by hand, here are all three on the same $100 bet.
Decimal Odds
Decimal odds give you the total return per $1 staked, stake included. Multiply your bet by the decimal number to get the full payout. A $100 bet at 2.50 returns $250 total, which is $150 profit, the same as +150. A $100 bet at 1.50 returns $150 total, or $50 profit, matching -200. To find profit alone, subtract 1 from the decimal first, so 2.50 becomes 1.50 times $100, which is $150.
Fractional Odds
Fractional odds show profit as a ratio of your stake. Multiply your bet by the fraction to get profit. A $100 bet at 3/2 wins $100 times 1.5, or $150 profit, again matching +150. A $100 bet at 1/2 wins $50, the same as -200. Fractions read as profit over stake, so 5/1 pays $500 on $100 and 1/5 pays $20 on $100.
How Parlay Payouts Multiply
A parlay ties several bets into one ticket, and every leg has to win for it to cash. The payout is not the sum of the legs. It is the product, because your winnings ride forward onto each new leg. The clean way to calculate it is to convert every leg to decimal odds, multiply them together, then multiply by your stake.
Take two standard -110 legs. Each is about 1.91 in decimal. Multiply 1.91 by 1.91 and you get roughly 3.64, so a $100 two-leg parlay returns about $364 total, or $264 in profit. Add a third -110 leg and the decimal climbs to about 6.96, turning $100 into roughly $696 total and $596 in profit. That multiplying effect is why a modest three-team parlay pays far more than three separate bets, and also why the odds against hitting it grow just as fast.
Mixed legs behave the same way. Pair a +150 leg (2.50 decimal) with a -200 leg (1.50 decimal) and you get 2.50 times 1.50, or 3.75. A $100 bet returns $375 total and $275 in profit. If you build these tickets often, our parlay calculator multiplies every leg for you, so you see the payout before you lock the ticket.
Final Thoughts
If I bet $100, how much do I win comes down to two quick formulas and one habit. Plus odds hand you that number in profit, minus odds pay less than your stake, and your $100 always comes back on a winner. Keep the reference list close until the math is automatic, then put your energy where it actually moves your bottom line: finding the book that pays the most on the bet you already want. Run a few lines through an odds comparison screen and a parlay calculator, and the payout starts working for you instead of feeding the vig.
