How to calculate multi odds
Multiply the decimal odds of each leg, then multiply by your stake. Two legs at 1.80 × 2.00 = 3.60. A $50 winning multi returns $180, including $130 profit.
For a single bet, use just one price. Our parlay and multi guide explains how the combined bet works.
Does this calculate Same Game Multi prices?
A standard multi multiplies the individual leg prices. Same Game Multi legs can be related, so bookmakers calculate a separate combined price. Enter that quoted price in Single bet mode to check its payout.
What if one of my legs is void?
For a standard multi where a void leg is removed, delete that leg and calculate with the remaining prices. If only one leg remains, use Single bet mode.
What does implied probability mean?
It is 100 divided by the combined decimal odds. At 3.60, the implied probability is 27.78%. It describes the price, not an independent estimate of your chance of winning.
Will changing odds formats change my payout?
No. Decimal 1.80, American −125 and fractional 4/5 represent the same price. Changing the format converts each valid leg and keeps the same potential return. Displayed conversions are rounded.
