Parlay calculator
Add each leg's decimal odds to get the combined price, the probability every leg wins, and what the bet returns.
Blank or invalid rows are ignored, so the combined price only counts the 2 legs you actually filled in.
Legs multiply. Two prices of 2.00 combine to 4.00, and four combine to 16.00. The return grows quickly, which is the appeal, and the probability falls just as quickly, which is the cost: four coin flips at 2.00 come in 6.25% of the time.
The margin compounds too. A bookmaker's cut is built into every price, so a parlay pays it once per leg. That is why an accumulator is a worse bet than its legs are individually, even when every leg is a bet you would happily make on its own.
We publish parlays deliberately small for that reason, and every parlay we publish is settled and recorded as one ticket, win or lose.

Every pick we publish carries the model's probability, the odds we took and the settled result, losers included.
