How Soccer Parlays Work: A Complete Beginner's Guide
If you're new to soccer betting in America, the term "parlay" comes up constantly. DraftKings and FanDuel highlight parlay boosts on their homepages. Sports bars have betting slips with parlay lines checked. Every sportsbook makes it sound simple, but understanding exactly how parlays work and how your money grows (or disappears) requires some clarity.
This guide breaks down the mechanics of soccer parlays for absolute beginners.
The Basic Concept
A parlay is a single bet that combines two or more separate selections. Instead of placing $100 on each of three different soccer matches, you place one $100 parlay combining all three. Your original $100 stake stays in play, and your potential winnings from the first match roll forward to the second match, then to the third.
The trade-off is clear: every single selection must win. A loss on any leg ends the entire parlay.
A Concrete Example
Let's walk through a real three-leg soccer parlay to show exactly how the money moves.
You place a $100 parlay on:
- Manchester City (-110) vs. Sheffield United
- Liverpool (-120) vs. Bournemouth
- Arsenal (-150) vs. West Ham
All three selections are moneyline bets (pick the winner).
Leg 1: Manchester City vs Sheffield United
Manchester City is listed at -110. This means you need to risk $110 to win $100.
If Manchester City wins (which you expect), you've won $100 on your original $100 stake. But here's the parlay magic: you don't cash out that $100. Instead, it rolls forward to Leg 2.
You now have $200 in play for the next match (your original $100 plus your $100 winnings).
Leg 2: Liverpool vs Bournemouth
Liverpool is at -120. This means a $120 bet wins $100.
You have $200 riding on this match now. Using -120 odds, your $200 wins $166.67. (This is where the math gets important; we'll explain the calculation shortly.)
If Liverpool wins, you now have $366.67 in play for Leg 3. This is the "roll" everyone talks about in parlays.
Leg 3: Arsenal vs West Ham
Arsenal is at -150. This means a $150 bet wins $100.
Your $366.67 is now riding on this final leg. At -150 odds, your $366.67 wins $244.45.
Total parlay payout: $366.67 + $244.45 = $611.12
You started with $100, so you won $511.12. Your payout is roughly 5-to-1 on your money.
This is why parlays excite bettors: turning $100 into $600 is far more exciting than the 10% return you'd get from winning a single straight bet at -110.
How American Odds Work in Parlays
To understand parlays, you need to understand American odds, because parlay calculations depend entirely on them.
Reading American Odds
American odds use either negative numbers (favorites) or positive numbers (underdogs).
Negative odds (-110): You risk that amount to win $100. So -110 means risk $110 to win $100. A -200 favorite means risk $200 to win $100.
Positive odds (+150): You win that amount on a $100 bet. So +150 means a $100 bet wins $150. A +200 underdog means a $100 bet wins $200.
Converting Odds to Decimal
Parlay calculations are easier with decimal odds. Here's how to convert:
For negative odds: Divide 100 by the absolute value and add 1.
- -110 becomes: (100/110) + 1 = 1.909
For positive odds: Divide by 100 and add 1.
- +150 becomes: (150/100) + 1 = 2.50
Calculating Parlay Returns
Once you have decimal odds, parlay math is simple multiplication.
Multiply all the decimal odds together, then multiply by your stake.
Using our example with decimal odds:
- Manchester City at -110 = 1.909
- Liverpool at -120 = 1.833
- Arsenal at -150 = 1.667
Multiply them: 1.909 × 1.833 × 1.667 = 5.82
Your parlay odds are now 5.82-to-1. On a $100 bet, you win $482 profit (or $582 total payout including your original stake).
This matches our earlier calculation pretty closely (small differences due to rounding).
The Simplified Formula
Parlay payout = Stake × (Decimal odds 1 × Decimal odds 2 × Decimal odds 3...)
For a $100 parlay at 5.82 decimal odds: $100 × 5.82 = $582 total payout.
Minimum and Maximum Parlay Legs
Minimum Legs
Most American sportsbooks require at least two legs for a parlay. You can't parlay a single match to yourself. Two-leg parlays exist but often have weaker payouts unless the matches have longer odds.
Some sportsbooks (especially those offering same-game parlays) allow just two legs. Others require three. Check your sportsbook's rules before building.
Maximum Legs
Most sportsbooks allow up to 15 legs in a parlay, though some go higher. A few limit by payout rather than leg count. For example, a sportsbook might cap parlay payouts at $1,000,000, which effectively limits how many legs you can include depending on odds.
In practice, bettors rarely go beyond 8-10 legs because the mathematical difficulty of hitting all selections becomes astronomical.
How Draws Affect Soccer Parlays
In soccer, matches can end in a draw. But American sportsbooks don't offer a three-way moneyline on most parlay selections.
Instead, the moneyline is two-way: Team A wins or Team B wins. A draw means your parlay loses, even if neither team you picked won the match.
This is important. A team you selected draws, and your four-leg parlay loses entirely.
Some sportsbooks offer draw-no-bet options where a draw refunds your bet rather than losing it. If available for parlays, this adds flexibility but often at slightly lower odds.
Odds Increments and Rounding
You'll notice that parlay calculations often result in non-round numbers: $611.12 instead of $611.
This is normal. Sportsbooks use precise decimal calculations, and payouts are calculated to the penny. Most will round to the nearest dollar or cent depending on their policy.
If you see a parlay listed as paying "5.82-to-1," that's the exact ratio before applying it to your stake.
What Happens if One Leg Loses
This is the critical rule: if any single leg loses, the entire parlay is lost.
Your four-leg parlay has three legs hitting and one leg losing? The entire parlay is a loss. You get nothing.
This is why parlays are higher-risk than straight bets. Three straight bets at -110 each might result in two wins and one loss, netting you +$100 (two wins minus one loss). The same three bets in a parlay format results in a complete loss.
Different Odds Combinations
Different sportsbooks might offer slightly different odds for the same match. A parlay built on DraftKings might have different total odds than the same parlay on FanDuel because the individual match odds vary by 5-10 cents.
This is why shopping for the best parlay odds across sportsbooks matters. Over time, getting the best available odds significantly impacts your results.
When Does the Parlay Lock In
When you place a parlay, the odds lock in immediately. If Manchester City is at -110 when you submit your parlay, that -110 is your odds even if they move to -130 five minutes later.
This matters strategically. Sharp bettors monitor line movement and place parlays just before they expect movement, locking in better odds.
Parlay Legs From the Same Match
Some parlays include multiple legs from the same match. For example, you might have:
- Arsenal to beat Tottenham (moneyline)
- Arsenal to win by exactly one goal (spread)
- Saka to score first (player prop)
All three are from the Arsenal-Tottenham match. These are called "same-game parlays" or SGPs, and they have special considerations. The odds don't simply multiply because these outcomes are correlated. A sportsbook will adjust the odds (often lower) to account for the correlation.
We cover same-game parlay specifics in the dedicated SGP article.
Fractional and Decimal Odds Alternatives
American sportsbooks primarily use American odds (-110, +150, etc.), but some international sites use decimal odds or fractional odds.
Decimal odds (common in Europe) make parlay math easier because you simply multiply them directly without conversion.
Fractional odds (common in UK betting) require conversion before multiplication.
If you use multiple sportsbooks, familiarize yourself with different odds formats. Most major US sportsbooks (DraftKings, FanDuel, BetMGM, Caesars, bet365) display American odds by default.
How Parlay Boosts Work
Sportsbooks frequently offer parlay boosts: a percentage increase to your parlay odds.
A "25% parlay boost" means a parlay that normally pays +500 (6.00 decimal odds) gets boosted to +625 (7.25 decimal odds).
Boosts apply after odds calculation. Your three-leg parlay's natural odds are multiplied, then the boost percentage is applied.
Some boosts have restrictions: they might only apply to parlays with four legs or more, or only on specific sports/leagues. Always read the fine print.
Correlated Parlays and Sportsbook Restrictions
Sportsbooks are aware of correlation. They won't allow parlays where both selections are essentially the same bet. For example, you can't parlay "Arsenal to win" with "Arsenal to score 3+ goals in the first half" because these are so highly correlated.
However, sportsbooks do allow some correlation. "Arsenal to win moneyline" and "Arsenal to win by 1+ goal (spread)" can often be parlayed together, though the odds won't simply multiply due to correlation.
If you try to build a parlay on a sportsbook and certain combinations aren't available, it's because the sportsbook has deemed them too correlated.
Live Parlay Bets
Most sportsbooks now allow live parlays during matches. You can build a parlay on remaining matches after some games have started or finished. The odds adjust based on live line movement.
Live parlays work the same way as pre-match parlays: all selections must hit for the entire parlay to cash.
Moneyline vs Other Markets in Parlays
Moneyline parlays are the simplest and most common. But you can parlay:
- Over/under goals
- Both teams to score
- Goal spreads
- First goalscorer props
- Player stat props
Each market has different odds and different correlation with other markets. Mixing different market types in a single parlay can create better risk-reward ratios than parlaying three moneylines.
