If any active leg loses, the whole parlay loses and you lose US$100.00. The combined price is not a prediction of the chance of winning.
Returns are calculated from unrounded combined decimal odds. Displayed combined odds are rounded; actual bookmaker pricing and payout rounding may differ.
How American parlay odds work
Convert each leg to decimal, multiply the decimal prices, then convert the total back to American odds. For positive American odds: decimal = 1 + odds ÷ 100. For negative odds: decimal = 1 + 100 ÷ the absolute odds.
For example, −110 and +150 combine to approximately 4.7727 decimal or +377.27 American. A 100 stake returns about 477.27 including stake, with 377.27 net profit if both win.
Standard, independently priced parlays only. Do not use this for correlated same-game parlays, teasers, boosts or special promotions. Push / void legs count as 1.00; half wins, half losses, dead heats, commissions, taxes and payout caps are not modelled. Always check the bookmaker’s settlement rules.
Calculation tools, not betting recommendations. Nothing is added to your ledger and no bets are placed. Currency changes the display only, not exchange rates. Gambling involves risk—only stake what you can afford to lose.
