A parlay only pays if every leg wins, and each leg carries its own bookmaker margin. Turning on fair-odds shows how that margin compounds — the EV of a parlay is usually worse than betting the legs singly.
A parlay (or accumulator) rolls several bets into one: every leg has to win, and the odds multiply together. Three legs at 2.10, 1.80 and 1.79 combine to 6.77, turning a £10 stake into a £67.66 return.
The catch is that the bookmaker's margin compounds with the odds. Each leg carries a slice of overround, so a parlay's true expected value is usually worse than betting the legs one at a time. This calculator shows the price and payout so you can judge it.
FAQ
- How are parlay odds calculated?
- Multiply the decimal odds of every leg together. 2.00 × 1.50 × 1.80 = 5.40. The payout is that figure times your stake.
- Why are parlays considered bad value?
- Because the bookmaker's edge is applied to each leg and then multiplied. A small margin per leg becomes a large combined drag over four or five legs.
- When can a parlay make sense?
- When the individual legs are genuinely +EV, or when correlated outcomes are priced as if independent. Otherwise singles are usually better.
