Parlay (Accumulator) Odds & Payout Calculator
Parlay (Accumulator) Odds & Payout Calculator
Enter the decimal odds for each leg of your parlay (separated by commas) along with your stake, and this calculator finds the combined odds and total payout.
A parlay — also called an accumulator or combo bet — combines multiple individual bets into a single wager by multiplying all their decimal odds together, but every single leg has to win for the parlay to pay out at all; a single lost leg loses the whole bet. Because the odds compound multiplicatively rather than adding together, even fairly modest individual odds grow quickly across several legs — three legs at 1.5 each combine to roughly 3.375, turning what looked like three modest single bets into a considerably higher-risk, higher-reward combined wager.
- A parlay (also called an accumulator or combo bet) combines multiple individual bets into one, multiplying all their decimal odds together — every leg must win for the parlay to pay out.
- Combined odds grow multiplicatively, not additively, so even modest individual odds compound quickly: three legs at 1.5 each combine to 1.5 × 1.5 × 1.5 = 3.375, not 4.5.
- Higher combined odds mean a bigger potential payout, but also a lower overall chance of winning, since every single leg has to land correctly.
How do I calculate parlay odds?
Multiply the decimal odds of every leg together. The result is your combined odds, which you then multiply by your stake to get the total payout.
What is the combined odds of legs at 1.5, 2.0, and 1.8?
1.5 × 2.0 × 1.8 = 5.4.
