How to use the parlay calculator
Decimal odds multiply together for active legs. The combined odds multiply your single parlay stake to produce the total return if all active legs win. A void leg contributes a multiplier of one.
Combined odds = odds 1 × odds 2 × …; net profit = stake × (combined odds − 1)A worked example
Two +100 legs each have decimal odds of 2.00. Together they produce 4.00 decimal odds. A $100 winning parlay returns $400 total, including the original stake, for $300 net profit.
What the numbers can tell you
This models a standard fixed-odds parlay. Same-game parlays, correlated selections, boosts, dead heats, and operator-specific void rules can change the offered payout. Multiplying prices does not determine the true chance of winning.
Frequently asked questions
What happens if a leg is void?
This calculator removes the void leg from the price multiplication. If every leg is void, total return equals the stake and profit is zero. Check the operator’s actual settlement rules.
Does this calculate a same-game parlay?
It multiplies the entered prices without a correlation adjustment. Use the actual combined price from the operator when selections are dependent.
