Round Robin Parlay Calculator
Calculate round robin parlay combinations, total stake and potential payouts. Compare exact or up-to parlay sizes and model wins, losses and pushes.
Enter a stake per parlay and the original odds for each selection. Choose a parlay size, then set hypothetical results to see the total cost, payout and net profit.
Use 3 to 12 selections. Enter ungrouped USD amounts in whole cents. Changing an odds format clears that selection’s odds.

| Selections | Payout if every selection wins | Scenario payout (stake included) | Scenario net profit / loss |
|---|---|---|---|
| 1 + 2 | $40.00 | $40.00 | $30.00 |

| 2 + 3 | $40.00 | $40.00 | $30.00 |
Standard independent parlays only. A loss loses that parlay; a push removes that selection; an all-push parlay refunds its stake. A one-leg remainder pays as a single. Each parlay payout is rounded down to whole cents before totals are added. Bookmaker rules may differ. Fees, taxes, promos, free bets, same-game pricing and eligibility rules are excluded.
How to use the round robin calculator
- Enter the stake for EACH parlay and the odds of every selection. The calculator multiplies your stake by the number of combinations to show total risk.
- Choose an exact parlay size, or include every size from 2 up to your chosen size. With five selections, sizes 2 through 4 make 25 separate parlays.
- Set each scenario result to win, loss or push. Compare the scenario payout with the total stake to see net profit or loss.
Example: three selections at +100, combined in pairs with $10 on each parlay, create three bets costing $30. If all win, the total payout is $120 and net profit is $90. If one selection loses, the remaining winning pair pays $40, leaving $10 net profit.

How many bets are in a round robin?
For n selections and an exact size k, the number of parlays is n! / (k! × (n − k)!). Four selections in pairs create six parlays. Up-to mode adds the counts for all sizes from 2 through k. Selecting all n selections as the exact size creates one parlay.
Is the entered stake the total cost?
No. The amount is staked on each individual parlay. Total stake equals the stake per parlay multiplied by the number of combinations. Payout includes returned stakes; net profit subtracts the full cost of all combinations.
What happens when a selection pushes or is void?
This model removes the pushed selection from each affected parlay. A remaining single selection pays at its original odds, and a parlay consisting entirely of pushes refunds its stake. A loss on any selection makes that parlay lose. Check the operator’s settlement rules, which may differ.
Does the calculator place round robin bets or predict results?
No. It models hypothetical, independent parlays with the prices and results you enter. It does not predict outcomes or guarantee a profit, and it does not imply that round robin betting is offered on this site. Same-game pricing, fees and special settlement rules are not modeled.
