How a parlay payout works
A parlay (or accumulator) combines several bets into one ticket. It only pays if every leg wins — which is why the payout is so much larger than a single bet. We multiply each leg’s decimal odds together to get the combined price, then apply your stake to get the payout and profit.
The trade-off: each leg you add lowers your overall chance of winning. More legs means a bigger payout but a longer shot. Tracking your parlays over time (free in Bankroll Guardian) shows whether they’re actually profitable for you, or just fun.
