Round Robin Parlay Payout Calculator

Choose your legs, enter each American price and mark every result as a win or loss. The calculator settles every smaller parlay in the round robin.

Your total stake is this amount multiplied by the number of combinations.

Formula

Combinations = C(n, r). Each winning combination pays stake × the product of its decimal odds. Net profit = total payout − total stake.

Worked examples

4 legs, by 2s. C(4,2) = 6 parlays. Three winning legs and one losing leg produce 3 winning combinations.

FAQ

What does stake per combination mean?

A $10 stake across six combinations risks $60 total. It is not a $10 total round-robin stake.

What happens when one leg loses?

Only combinations containing that losing leg lose. Combinations made entirely from winning legs still pay.
