Parlay calculator

Multiply decimal odds

At 2.00, 1.50 and 2.00, the combined price is 6.00. A $10 winning parlay returns $60, including the stake. The calculation describes the quoted payout, not a recommendation to combine more selections.

Won, lost and void legs

Mark each selection with its settlement status. A void selection contributes a multiplier of one. If any non-void selection loses, the cash return is zero. An all-void cash ticket returns its stake; an all-void bonus ticket has no cash payout in this model, and token reinstatement depends on the offer.

Same-game prices need different treatment

Outcomes in the same event may be correlated. Multiplying independent prices cannot reproduce a sportsbook’s same-game parlay model. Use a supplied combined price in the main odds calculator instead of inventing a correlation adjustment.

How to calculate parlay odds and payout

Convert every price to decimal odds and multiply the leg prices. Multiply the result by the stake for gross return; subtract the stake for net profit. A two-team parlay at 2.00 and 1.50 has combined odds of 3.00, so $10 returns $30 and earns $20.

A four-team parlay with every leg at decimal 2.00 has odds of 16.00. A $10 winning ticket returns $160 and earns $150. Use Add leg to build your own combination; the same calculation applies to an accumulator or a moneyline parlay.

NFL, baseball and sports parlays

A moneyline parlay and an accumulator use the same product of decimal prices. The tool calculates your entered selections; it does not choose picks, fetch live prices or predict a winner.

For independent legs with probabilities 50%, 60% and 40%, the all-win chance is 0.5 × 0.6 × 0.4 = 12%. Price-implied probabilities can include margin. Same-game selections may be correlated, so multiplying their individual probabilities does not generally give the correct combined chance.

Voids, parlay hedging and cash-out

A fully void leg has multiplier one; any lost leg loses the standard parlay; a pending leg leaves the displayed payout conditional. Operator rules for dead heats, partial voids and boosts can differ.

Use the parlay hedge calculator for a two-outcome final leg. For a quoted cash-out offer, compare the offer with the cash-out value calculation rather than treating the final leg’s odds as the whole ticket. A round robin calculator creates separate smaller parlays instead of one all-or-nothing ticket.

A quoted parlay price and a forecast are different inputs

The product of decimal prices specifies the independent-price ticket’s payout. Its reciprocal is a price-implied chance, not a validated forecast. If three independent selections each have an estimated 60% chance, their all-win chance is 21.6%, even if the displayed prices imply something different.

One lost leg makes the standard ticket lose. A void removes that leg’s multiplier. The example buttons let you compare all-won and one-void settlement without retyping each row. For partially winning tickets, use the round-robin combinations rather than assume one parlay pays partially.

Profit boosts and bonus stakes: check the cash return

Enter American, decimal or fractional prices directly. The calculator converts them before multiplying, without rounding between legs. For combined decimal odds D and boost b%, the boosted price is 1 + (D − 1) × (1 + b/100). A bonus stake is excluded from the winning cash return. Promotions can set minimum legs, maximum winnings or different void rules; those terms are not inferred.
