Formula for Calculating Round Robin Parlays
1. Number of Parlays
For n selections and k legs per parlay, the number of unique parlays is:
Number of Parlays = n! / (k! × (n – k)!)
Where:
- n = total number of selections
- k = legs per parlay
2. Parlay Payout Calculation
Parlay Payout = Stake × (Odds1 × Odds2 × … × Oddsk)
For each parlay, multiply the odds of the selected events and multiply by the stake to get the payout.
3. Total Potential Profit
Total Profit = Sum of All Parlay Payouts – Total Stake
This ensures bettors can see the potential maximum profit from all combinations.
Example Calculations
Example 1: 3 Selections, 2-Leg Parlays
- Selections: A, B, C
- Odds: 2.0, 1.5, 2.5 (decimal odds)
- Stake: $10 per parlay
Step 1: Number of Parlays
- Number of 2-leg parlays = 3! / (2! × (3 – 2)!) = 3 parlays
- Combinations: AB, AC, BC
Step 2: Calculate Payouts
- AB = 10 × (2 × 1.5) = $30
- AC = 10 × (2 × 2.5) = $50
- BC = 10 × (1.5 × 2.5) = $37.50
Step 3: Total Potential Profit
- Total Stake = 3 × $10 = $30
- Total Payout = 30 + 50 + 37.50 = $117.50
- Total Profit = 117.50 – 30 = $87.50
Example 2: 4 Selections, 3-Leg Parlays
- Selections: W, X, Y, Z
- Odds: 1.8, 2.0, 1.6, 2.2
- Stake: $5 per parlay
Step 1: Number of Parlays
- 4C3 = 4! / (3! × 1!) = 4 parlays
- Combinations: WXY, WXZ, WYZ, XYZ
Step 2: Calculate Payouts
- WXY = 5 × (1.8 × 2 × 1.6) = $28.80
- WXZ = 5 × (1.8 × 2 × 2.2) = $39.60
- WYZ = 5 × (1.8 × 1.6 × 2.2) = $31.68
- XYZ = 5 × (2 × 1.6 × 2.2) = $35.20
Step 3: Total Profit
- Total Stake = 4 × $5 = $20
- Total Payout = 28.80 + 39.60 + 31.68 + 35.20 = $135.28
- Total Profit = 135.28 – 20 = $115.28
