Parlay Calculator
A parlay, also called an accumulator, combines several bets into one wager where every leg must win for the ticket to pay. The upside is that the odds multiply, so a modest stake can return a large payout, but the combined probability of winning drops with every leg you add. This calculator lets you enter each legs odds in American or decimal format, then shows the total parlay odds, the full payout on your stake, the profit and the combined implied probability that all selections land. Use it to see exactly how much a longshot parlay is really worth and how quickly your true chance of winning shrinks. All calculations happen locally in your browser.

Frequently asked questions
How are parlay odds combined?
The decimal odds of every leg are multiplied together, so the total return grows quickly but the combined win probability is the product of each leg chance.
How many legs can it handle?
It combines up to eight legs entered in American or decimal odds, giving the total parlay odds, the payout on a stake and the overall win probability.
Why do parlays pay so much yet win rarely?
Multiplying odds inflates the payout, but every leg must win, so the combined probability multiplies down; the tool shows both figures so the trade-off is clear.
