What Is a Parlay Bet?
A parlay (also called an "accumulator" or "multi-bet") combines two or more individual bets into a single wager. All selections must win for the parlay to pay out, but the potential payout is much higher than betting each leg separately.
How Parlay Odds Are Calculated
Parlay odds are calculated by multiplying the decimal odds of each leg together. For example, a 2-leg parlay with -110 odds on both legs:
📐 The Formula
Parlay Decimal Odds = Leg 1 Decimal × Leg 2 Decimal × Leg 3 Decimal...
Example: 1.91 × 1.91 = 3.65 decimal odds (+265 American)
Parlay Payout Chart
Here's what a $100 parlay pays at standard -110 odds per leg:
| Legs | True Odds | Payout | Profit | Win Probability |
|---|---|---|---|---|
| 2 | +264 | $364 | $264 | 27.5% |
| 3 | +596 | $696 | $596 | 14.4% |
| 4 | +1,228 | $1,328 | $1,228 | 7.5% |
| 5 | +2,435 | $2,535 | $2,435 | 3.9% |
| 6 | +4,741 | $4,841 | $4,741 | 2.1% |
| 7 | +9,145 | $9,245 | $9,145 | 1.1% |
| 8 | +17,573 | $17,673 | $17,573 | 0.6% |
| 10 | +64,273 | $64,373 | $64,273 | 0.16% |
⚠️ The Math Isn't in Your Favor
While parlays offer exciting payouts, the house edge compounds with each leg. A 10-leg parlay at -110 odds has only a 0.16% chance of hitting. Sportsbooks love parlays because they're highly profitable for them.
Parlay Betting Strategy Tips
When Parlays Make Sense
Despite the math, there are situations where parlays can be strategically sound:
- Correlated parlays — When outcomes are linked (e.g., a team winning AND covering the spread)
- Small stakes, big events — Turning $10 into entertainment value for a full day of games
- Plus-money legs only — Parlaying underdogs where you have an edge
Common Parlay Mistakes to Avoid
- Adding legs just to increase payout (each leg decreases your win probability)
- Parlaying heavy favorites (the juice compounds quickly)
- Not comparing parlay odds across sportsbooks (they vary significantly)
- Treating parlays as your primary betting strategy
💡 Pro Tip
If you're going to bet parlays, stick to 2-3 legs maximum. The sweet spot is getting enhanced payout without astronomical odds against you. And always check if your sportsbook offers "same-game parlay insurance" or parlay boosts.
