Round Robin Parlay Calculator
How to Use This Round Robin Parlay Calculator
To use this round robin parlay calculator:
- First, select your odds format (American, decimal, fractional, etc.)
- Choose your selection count (how many events you're betting on).
- Choose your parlay size (how many selections you want in each parlay bet).
- Enter your stake amount (how much you're betting).
- Choose your stake type between "Stake Per Bet" and "Total Combined Stake". "Stake Per Bet" means you'll bet your stake amount on each parlay. "Total Combined Stake" means your stake amount will be split among all of your parlays.
- Choose whether to include smaller parlays. If you select "Yes" and have 4 as your "Parlay Size", all possible parlays containing 3 selections and 2 selections will also be added to the round robin.
- Enter the odds and outcome for each of your selections.
After you've entered valid data for all inputs, the calculator will automatically calculate your "Total Risk" (sum of all your bets), "Total Payout" (how much you'll be paid out for your bets given your stake amount, odds, and outcomes), "Profit" (total payout minus total risk), and "Max Win" (how much you'd win if all selections won).
Note: This round robin calculator is meant for simulating round robin parlay bets common in the United States and Canada. "Round Robin" bets refer to a different type of bet in the United Kingdom.
What is a Round Robin Parlay?
Round robins are combinations of parlay bets made from 3 or more selections. For example, a round robin containing 3 selections would consist of 3 separate 2-leg parlays:
- Parlay 1: Selection A & Selection B
- Parlay 1: Selection A & Selection C
- Parlay 1: Selection B & Selection C
In the example above, if all your selections win, you'd win all your parlays. If two selections win, you'd win one parlay and lose the other two. If all selections lose, you'd lose all of your parlays.
As you add selections, the number of parlays in your round robin can grow rapidly:
- A round robin containing 3 selections of a 2 parlay size contains 3 (2-leg) parlays.
- A round robin containing 5 selections of a 4 parlay size contains 5 (4-leg) parlays.
- A round robin containing 5 selections of a 2 parlay size contains 10 (2-leg) parlays.
- A round robin containing 8 selections of a 7 parlay size contains 8 (7-leg) parlays.
- A round robin containing 8 selections of a 2 parlay size contains 28 (2-leg) parlays.
- A round robin containing 15 selections of a 14 parlay size contains 15 (14-leg) parlays.
- A round robin containing 15 selections of a 2 parlay size contains 105 (2-leg) parlays.
Things can get even crazier if you include all smaller possible parlays. For example, a round robin of 4 selections and a parlay size of 3 would contain all combinations of 3-leg and all 2-leg parlays possible from the 4 selections. By including the smaller 2-leg parlays, 10 total parlays are created instead of 4.
While we can't imagine anyone actually doing this, a round robin containing 15 selections that includes all parlays of sizes 2-14 would be made up of 32,751 individual parlays.
Pros and Cons of Round Robin Parlays
Compared to a single parlay, the primary advantage of round robins is that you can still get a payout when one of your selections loses. However, it's important to remember that there's more risk if you're betting more money on multiple parlays.
