Examples

Football (decimal odds)

NFL parlay: 1.80 × 1.95 × 2.10 × 1.85. $10 returns if all legs win.

Horse racing (fractional odds)

Racing parlay (four-fold) at 6/4, 7/4, 9/4, 3/1.

Fractional odds explained

  • Written as a/b (e.g., 5/2). This means you win a profit of a for every b you stake.
  • Profit = stake × (a ÷ b). Total return = stake + profit.
  • Quick convert to decimal: 1 + (a ÷ b). Example: 9/4 → 1 + 9/4 = 3.25.
  • Example: at 2/1, a £10 stake: profit £20, total return £30.

Formulas

Accumulator

Multiply all leg odds together, then multiply by your stake.

Profit = Return − stake.

Reasons for making a Parlay / Accumulator Bet

  • Increased chances of winning: Multiple combinations create more ways to get a return than a single bet.
  • Potential for significant returns: When several selections win, combined payouts can grow quickly.
  • Risk management: Some combinations can still return even if not all selections win.
