Free multi calculator
Multiply the decimal price of every leg. A multi pays the product, and wins only if every leg wins, so its chance is also the product of the legs' chances. Enter your legs below, or check what a bookmaker's same game multi pays against its legs. In the US a multi is called a parlay.

What are you checking?
SGM price
4.20
Legs multiplied
4.75
SGM against legs
-11.6%
The SGM pays 11.6% less than its legs multiplied. Legs that tend to land together can justify some of that; the rest is the bookmaker's margin on the combination.
18+. Arithmetic on the prices you enter, not a tip or a prediction. Prices can move, and bets can be limited or voided, before both are placed. Gambling Help Online: 1800 858 858.
The live version
The SGM comparison compares the same game multi price across bookmakers, so you can see which one pays most for the same legs.
Worked example. Two legs at 1.90 and 2.50 make a multi of 4.75, which implies a 21.05% chance. A same game multi priced at 4.20 on the same two legs pays 11.6% less than the legs multiplied (4.20 against 4.75).
What it assumes. For a multi, that the legs are in different games and independent. Legs in the same game move together, which is why a bookmaker prices a same game multi as a whole, and the same game check only compares that price with the legs multiplied. The calculator cannot say how much of the gap is fair and how much is margin.

Nothing in how they work: a multi (Australia and the UK, also called an accumulator) and a parlay (the US) both combine legs, and every leg has to win.
Each leg carries the bookmaker's margin and they compound when multiplied. A multi of several short prices can have a total margin well above any one leg's, which is why value hunters usually bet singles.
A multi with several legs from one game. Because the legs are linked, the bookmaker prices the combination itself, and it often pays less than the legs multiplied.
Take a sharp market's price and remove its margin with the no-vig calculator, then enter it as the leg's fair price in the multi mode.
