How to Use the Round Robin Calculator
Our round robin calculator is straightforward to use. Follow these simple steps to calculate your round robin bet payout:
Enter Total Bet Amount
Start by entering the total amount you want to wager on your round robin. This amount will be divided equally among all parlay combinations created.
Select Round Robin Size
Choose the size of your round robin (2-way, 3-way, 4-way, etc.). This determines how many selections will be in each parlay combination.
Enter Odds for Each Selection
Input the American odds for each selection in your round robin. You can enter odds in formats like +120, -140, +200, or -300. Add more selections using the "Add Selection" button.
View Results
The calculator automatically displays all parlay combinations, their odds, bet amounts, and potential winnings. You'll also see summary statistics including total parlays and maximum potential win.
What is a Round Robin Bet?
A round robin bet is a type of wager that creates multiple parlay combinations from a set of selections. Instead of making one parlay with all selections, a round robin creates all possible parlay combinations of a specified size.
For example, if you have 4 selections and choose a round robin 2-way, the calculator creates 6 separate 2-team parlays. If you have 5 selections and choose a round robin 3-way, it creates 10 separate 3-team parlays.
Round robin bets offer more flexibility than traditional parlays because you don't need all selections to win to get a payout. If some selections win, you'll still get paid on the parlays that include those winning selections. However, your total bet amount is divided among all parlay combinations, so each individual parlay has a smaller bet amount than if you made a single parlay.
Round robins are popular among bettors who want to cover multiple combinations while reducing risk compared to a single large parlay. Use our parlay calculator to compare round robin payouts with traditional parlay payouts.
How to Calculate a Round Robin Payout
Calculating a round robin payout involves several steps. Here's how the math works:
- Determine the number of parlay combinations using the combination formula: C(n, k) = n! / (k! × (n-k)!), where n is the number of selections and k is the round robin size.
- Divide your total bet amount by the number of parlays to get the bet amount per parlay.
- For each parlay combination, convert the American odds to decimal odds.
- Multiply the decimal odds together to get the parlay multiplier.
- Calculate each parlay payout: Bet Amount × Multiplier = Total Payout.
- Sum all winning parlay payouts to get your total round robin payout.
The formula for calculating round robin combinations is:
Number of Parlays = C(n, k) = n! / (k! × (n-k)!)
Bet Per Parlay = Total Bet Amount / Number of Parlays
Parlay Payout = Bet Per Parlay × (Decimal Odds 1 × Decimal Odds 2 × ...)
Round Robin Calculator Examples
Example #1: Round Robin 2-way with 4 Selections
If you have 4 selections (A, B, C, D) with odds of -110 each and choose a round robin 2-way with a total bet of $60:
- Number of parlays: C(4, 2) = 6 parlays
- Bet per parlay: $60 / 6 = $10 per parlay
- Each parlay has 2 selections at -110 (decimal: 1.91)
- Each parlay multiplier: 1.91 × 1.91 = 3.65
- Each parlay payout: $10 × 3.65 = $36.50
- If all 6 parlays win: $36.50 × 6 = $219.00 total payout
This round robin creates 6 separate 2-team parlays, giving you multiple chances to win even if not all selections are correct.
Example #2: Round Robin 3-way with 5 Selections
If you have 5 selections with mixed odds (+150, -120, -110, +200, -150) and choose a round robin 3-way with a total bet of $100:
- Number of parlays: C(5, 3) = 10 parlays
- Bet per parlay: $100 / 10 = $10 per parlay
- Each parlay combines 3 selections with their respective odds
- Parlay payouts vary based on which 3 selections are combined
- Maximum payout occurs when all 10 parlays win
This round robin creates 10 separate 3-team parlays, providing even more coverage and flexibility than a 2-way round robin.
Frequently Asked Questions About Round Robin Calculator
A round robin bet is a type of wager that creates multiple parlay combinations from a set of selections. Instead of making one parlay with all selections, a round robin creates all possible parlay combinations of a specified size. For example, a 4-selection round robin 2-way creates 6 separate 2-team parlays, while a 5-selection round robin 3-way creates 10 separate 3-team parlays. This gives you multiple chances to win even if not all selections are correct.
To calculate a round robin payout: 1) Determine how many parlay combinations will be created using the combination formula C(n, k), 2) Divide your total bet amount by the number of parlays to get the bet per parlay, 3) Calculate each parlay payout separately by converting odds to decimal, multiplying them, and applying the bet amount, 4) Sum all winning parlay payouts. Our round robin calculator does this automatically when you enter your selections, odds, round robin size, and bet amount.
A round robin calculator works by generating all possible parlay combinations of a specified size from your selections, calculating the payout for each parlay combination, and providing a detailed breakdown of all parlays along with summary statistics. Simply enter your selections with their odds, choose the round robin size (2-way, 3-way, etc.), enter your bet amount, and the calculator will show all parlay combinations and their potential payouts instantly.
A parlay combines all selections into one bet - all selections must win for the parlay to pay out. A round robin creates multiple smaller parlays from your selections, so you can win on some parlays even if not all selections win. However, your bet amount is divided among all parlay combinations in a round robin, so each individual parlay has a smaller bet amount than a single parlay with all selections.
The number of parlays created depends on the number of selections and the round robin size. Use the combination formula: C(n, k) = n! / (k! × (n-k)!), where n is the number of selections and k is the round robin size. For example, 4 selections with a 2-way round robin creates 6 parlays, while 5 selections with a 3-way round robin creates 10 parlays. Our calculator automatically shows the total number of parlays created.
Yes, you can combine different types of bets in a round robin, such as moneylines, point spreads, and totals. As long as the bets are from different games or events, you can include them in your round robin selections. However, you typically cannot include bets from the same game or correlated outcomes in the same round robin.
