How it works

Multiply the prices, not the probabilities.

American odds are first converted to decimal form. The calculator multiplies those decimal prices, which captures the compounding payout across every leg.

The implied probability is the inverse of the combined decimal odds. It reflects the price only; it does not account for correlation between legs or prove the parlay is fairly priced.

Questions, answered

How are parlay odds calculated?

Convert each leg to decimal odds, multiply the decimal prices, then convert the result back to American odds.

How is a parlay payout calculated?

Multiply the stake by the combined decimal odds. Profit is the total payout minus the original stake.

Does one losing leg lose the whole parlay?

For a standard parlay, yes. Every leg must win unless a sportsbook's specific rules treat a push or cancellation differently.
