Three -110 legs parlayed together produce combined American odds of roughly +596, meaning a $100 stake returns approximately $696.29 in total — about $196.29 in net profit. Here is the exact decimal-multiplication path that gets you there.
How do you convert -110 American odds to decimal?
American odds of -110 mean you risk $110 to win $100. The decimal equivalent is calculated as: 100 ÷ 110 + 1 = 1.909 (rounded to three decimal places). Every leg in this example carries that same -110 line — a typical point-spread price at most licensed US sportsbooks.
What is the step-by-step parlay odds calculation?
Once each leg is in decimal form, you multiply all three together:
- Leg 1: 1.909
- Leg 2: 1.909
- Leg 3: 1.909
- Combined decimal: 1.909 × 1.909 × 1.909 = 6.963
Multiply the combined decimal by your $100 stake: 6.963 × $100 = $696.29 total return. Subtract the original $100 stake and your net profit is $596.29, which converts back to American odds of approximately +596.

How does the 3-team parlay payout compare to separate bets?
If you placed three individual -110 bets of $100 each, winning all three would return roughly $272.73 in combined profit. The parlay returns $596.29 on the same three outcomes — more than double. That compounding is the draw, but the all-or-nothing rule means one wrong leg erases everything, no partial credit.
Parlays generate over 70% of sportsbook revenue precisely because the average house edge on a parlay is approximately 24%, far above the ~4.5% vig on a single-game spread bet. Every additional leg you add compounds not just your potential payout but the sportsbook's edge.
Where is a 3-team parlay legal?
Parlay betting is legal wherever a state has authorized sports wagering. More than 30 states plus Washington D.C. had done so as of 2024. Pennsylvania, Michigan, New Jersey, and Colorado are among the most active online parlay markets; Mississippi and Montana permit retail-only wagering, so online parlay tickets are not available there. Check the full state-by-state parlay legality guide before depositing.
Minimum age is 21 in the vast majority of legal states. Must be 21+. Gambling problem? Call 1-800-GAMBLER or visit the National Council on Problem Gambling.
Will a big parlay win trigger a tax form?
Yes — if your sports-betting winnings reach $600 or more and the payout is at least 300 times your wager, the sportsbook issues a W-2G to you and the IRS. A $100 stake paying $696.29 does not meet the 300× threshold (that would require a $30,000+ return on $100), but larger parlays absolutely can. All gambling winnings are taxable federal income regardless of whether a W-2G is issued. Read more about parlay taxes and state legality.
Quick reference: 3-team -110 parlay payout
| Leg | American Odds | Decimal Odds | Running Multiplier |
|---|---|---|---|
| Leg 1 | -110 | 1.909 | 1.909 |
| Leg 2 | -110 | 1.909 | 3.644 |
| Leg 3 | -110 | 1.909 | 6.963 |
$100 × 6.963 = $696.29 total return (+596 American odds). That is the canonical 3-team parlay bet example you will see cited across most major US sports betting guides — and the math holds at any licensed sportsbook offering standard -110 spread lines. Compare that figure against three separate single bets to decide which approach suits your bankroll.
