Questions about the parlay calculator
How are parlay odds calculated?
Multiply the decimal odds of every leg. A 3-leg parlay at 2.00, 1.50 and 1.80 has combined odds of 5.40, so a 10 stake returns 54.
Why do parlays usually cost more than single bets?
Each leg carries the bookmaker's margin, and the margins multiply. With a 5% margin per leg, a 4-leg parlay gives the bookmaker roughly a 19% edge.
These tools do the maths only. They can't predict results, and no betting system guarantees a profit.
