Enter the American odds for two to eight legs and a stake. The calculator multiplies the legs into one combined price and shows the payout if every leg wins.
Example: three legs at -110 each combine to about +596. A $10 stake returns $69.58, which is $59.58 of profit.
Every leg has to win for a parlay to pay. Three true coin flips win together one time in eight, so a fair price would be +700. The gap between +700 and +596 is the fee you pay on each leg, multiplied.
