Parlays & hedging
Parlay Calculator
Combine leg prices to estimate the total return, net profit and implied probability.
How to read your result
Total return includes your original stake. Net profit is what remains after subtracting that stake. The implied probability describes the combined price, not your true chance of winning.
Two −110 legs combine to decimal odds of about 3.645. A $25 stake returns about $91.12, including the stake, for a net profit of about $66.12.
Formula and assumptions
Combined decimal odds = D1 × D2 × … × Dn. Total return = stake × combined odds. Net profit = return − stake. Implied probability = 1 ÷ combined odds. This assumes standard independent-leg pricing with every leg winning. Same-game correlation, pushes, voids, boosts and sportsbook-specific rules can change the payout. Use the actual offered parlay price when those apply.
