Free bet payout calculator. Enter your stake and odds to see profit and total return, or add legs to calculate parlay odds and payout.
For a single bet, payout is your stake times the decimal odds; profit is payout minus stake. A parlay combines multiple bets into one — every leg must win — and the combined decimal odds are the product of each leg's decimal odds.
Each parlay leg carries the book's margin, so a 4-leg parlay stacks four margins against you. Parlays pay big but hit rarely.
Convert each leg to decimal odds and multiply them together, then multiply by your stake for the payout.
Because every leg has to win; the combined probability is the product of each leg's probability.
