Parlay odds are the combined price of every leg in the bet, multiplied together. Two -110 legs pay about +264. Three pay about +596. The number looks generous because it is, and that’s the part worth understanding before you build a slip.
There is no bonus multiplier hiding in there. A parlay is one wager on several outcomes, and the payout is the product of the individual prices. Multiply, don’t add.
Below: what the number means, why the book’s margin grows with each leg, and how round robins, same game parlays and hedges change the math.
What are parlay odds, in plain terms?

They are the price of a single bet that only cashes when every leg wins. Books quote each leg in American odds and multiply the decimal versions behind the scenes.
The whole process is three steps:
- Convert each leg to decimal. +150 becomes 2.50, -200 becomes 1.50, -110 becomes 1.91.
- Multiply the decimals. Three legs at 1.91 come to 6.96.
- Convert back. Decimal 6.96 is roughly +596.
That’s it. The free parlay calculator handles the conversion if you’d rather not do decimals in your head.
| Legs at -110 | Decimal | American | Implied probability |
|---|---|---|---|
| 1 | 1.91 | -110 | 52.4% |
| 2 | 3.64 | +264 | 27.4% |
| 3 | 6.96 | +596 | 14.4% |
| 4 | 13.29 | +1229 | 7.5% |
Key takeaway: the payout and the implied probability are two views of one number. Decimal 6.96 means roughly a 14.4% chance as priced.
For the longer ladder, including the 5 and 6 leg versions, our breakdown of parlay payouts by leg count goes deeper. If you’re still fuzzy on how the bet itself is structured, start with how a parlay works first.
Where the extra margin comes from
Every leg carries the book’s cut. Stack legs and the cut stacks with them.
Run the arithmetic. A -110 line implies 52.4% on each side, so the two sides add to 104.8%. That extra 4.8 points is the margin, about 4.5% of the total. On a single bet, it’s small enough to ignore.
Now assume each leg of a three-team ticket is a true coin flip. Fair decimal would be 2.00 per leg, or 8.00 for the whole thing. Priced at 1.91 per leg, the same ticket pays 6.96. Divide 6.96 by 8.00 and you get 0.87, which means the hold is about 13% instead of 4.5%.
That’s compounding, not a pricing trick. Four legs priced the same way carry roughly 17%, and the curve keeps rising from there.
None of this makes parlays a bad bet in every case. It does explain why a five-leg ticket feels closer to a lottery ticket than a two-leg one.
Why two books post different prices for the same parlay
Because the books don’t agree on every leg. Build the same four-leg slip at three sportsbooks and you can see three different payouts, sometimes with individual legs priced a full 10 cents apart.
The fix is boring. Compare the legs, not the ticket. A better price on one leg lifts the whole combined number, and you get that improvement at no cost beyond the extra tap.
StatsBench shows the best available price on a prop across 30+ sportsbooks, DFS apps and exchanges, plus a +EV % on every prop you can sort by Best EV. The NFL board in the Prop Finder puts those prices side by side (it needs a free account). Line shopping is the least glamorous edge in betting and one of the most reliable.
What is a round robin parlay?
A round robin is a set of smaller parlays built from the same group of picks. Choose four teams and play “3s” and you hold four separate three-team tickets, each covering a different combination.
Why bother? Because it widens the landing zone. If three of your four legs win, a straight four-teamer is dead, but one of your four round-robin tickets cashes.
The trade-off is cost. Four tickets cost four times a single slip, and the maximum return is smaller than one clean four-leg payout would have been. Round robins suit a bettor who likes several legs but doesn’t want the whole result to hinge on all of them landing.
The mechanics of staking and combining are covered step by step in our guide to playing parlays.
What is a same game parlay?
A same game parlay bundles legs from one matchup into a single price. Books usually shorten the payout compared to simply multiplying the legs, because those legs aren’t independent events.
Picture a quarterback’s passing yards and his top receiver’s receiving yards. Both need the same drives to go well. When one hits, the other is likelier to hit too. The book prices that relationship instead of pretending the two legs are unrelated.
That’s why the SGP price and the multiplied price rarely match. Sometimes the bundled version is a worse deal than two separate bets, sometimes it’s better. Check before you accept.
How do you hedge a parlay?
A hedge is a bet on the other side of the outcome you’re exposed to, usually on the final leg. You give up some upside so the return is similar whichever way that last leg lands.
The stake isn’t guesswork. It depends on the price of the remaining leg and how much upside you’re willing to leave behind. Run it through the hedge calculator instead of improvising at 11pm.
Hedging isn’t automatic, either. If the last leg still looks like a good price on its own, betting against it gives back the edge you started with.
A real three-leg example from a November 2026 slate

Prices matter more than labels. Here are three NFL props from a StatsBench snapshot taken in November 2026, with the recent record and the best price we had on each.
| Leg | Market | Record | Best price |
|---|---|---|---|
| Breece Hall (NYJ @ KC) | Rushing attempts over 10.5 | 10/10 | -110 |
| Will Reichard (MIN vs BUF) | Kicking points over 6.5 | 9/10 | -110 |
| Danielle Hunter (HOU @ LAC) | Sacks over 0.5 | 8/10 | -120 |
Multiply the decimals: 1.91 x 1.91 x 1.83 = 6.68, or about +568. A $20 ticket returns roughly $134.
Whether that’s a good bet is a separate question. Those records are recent samples, not forecasts, and the 8/10 on a sack prop is a shakier leg than the 10/10 on rushing attempts. Sacks can die on a snap count, so check the role before you stack. Fresh angles land on the NFL player props page each week.
For the underlying stats, the official NFL stats hub is the cleanest source.
What the payout number doesn’t tell you
A big price and a good bet aren’t the same thing. +596 tells you what the ticket pays. It says nothing about whether those legs were priced correctly in the first place.
Long run, a parlay’s cost compounds the same way its payout does. That’s why experienced bettors treat a slip as a set of individual prices and do most of their work at the leg level, where the vigorish is smaller and easier to see.
Bet within your means, 21+, and treat a losing slip as variance rather than a hole to climb out of. If betting stops being fun, 1-800-GAMBLER is there.

Frequently Asked Questions
Do parlays pay better than straight bets?
They pay more, not better. The payout is larger because you’re taking on more risk, but the book’s margin compounds with every leg you add. A three-leg ticket at -110 prices carries roughly a 13% hold versus about 4.5% on a single bet.
How do I calculate a parlay payout by hand?
Convert each leg to decimal odds, multiply them together, then multiply by your stake. Three legs at 1.91 come to 6.96, so a $20 bet returns about $139 before rounding. Convert 6.96 back to American and you get roughly +596.
What does a round robin parlay pay?
It depends on how many combinations you buy and how many of them hit. A four-team round robin of 3s is four separate tickets, so you collect on whichever combinations come in and lose the rest. The maximum return is lower than one straight four-leg parlay.
Why is my same game parlay payout lower than the multiplied legs?
Because the legs are correlated. A quarterback’s passing yards and a receiver’s catches tend to move together, so the book prices the bundle as one related outcome instead of independent events. The discount reflects that relationship.
Can you hedge a parlay before the last leg finishes?
Yes, and that’s the usual approach. You bet the opposite side of the final leg so the return is similar either way. The right stake depends on the remaining leg’s price and how much upside you’re willing to give up.
