Parlay calculator: combined odds, return and void legs

How parlay odds are calculated

For a standard accumulator, multiply the decimal odds of its selections. Prices of 1.80, 2.00 and 1.50 give combined odds of 5.40. A winning C$10 cash stake then returns C$54, including that stake, for C$44 net profit.

Add a selection to see how both the combined price and the settlement change. Every selection must win under the ticket’s rules for the full return to apply. The larger number on a longer ticket is a conditional payout, not an increased likelihood of winning.

What happens to a void selection?

An ordinary void leg contributes a multiplier of 1.00. If the 2.00 selection in the example is void, the remaining 1.80 × 1.50 gives 2.70: C$27 total return and C$17 profit on C$10. If every leg is void, the calculation returns the original stake. A losing leg makes the standard accumulator’s return zero.

Same-game parlays and Bet Builders can have different void and repricing rules because their selections may be related. Use the accepted ticket’s quoted price for those products; multiplying standalone market prices does not reproduce a correlated ticket.

Use the amount you planned

The stake field applies to the whole ticket. All results use the same currency as that stake; the tool does not perform currency conversion. The calculation excludes free-bet stake deductions, boosts, taxes, commission and operator-specific rounding.
