Parlay Odds Calculator
Calculate total odds and payout for a parlay
The parlay odds calculator determines the combined price, payout, and profit for wagers that include multiple selections. In a parlay, every leg must win for the bet to cash, meaning the probability of success decreases as additional selections are added.
The calculator converts each leg into a consistent format and multiplies them to produce the final parlay odds. This reflects the true compounded probability of all outcomes occurring together rather than evaluating each leg in isolation.
For example, pairing a -110 selection with a +150 selection results in a combined price that is significantly higher than either individual bet. The increased payout reflects the lower overall probability of both outcomes winning simultaneously.
Seeing the final implied probability of the entire wager helps you understand exactly what must occur for the parlay to succeed. This allows you to evaluate risk more clearly and compare the combined bet against placing the legs separately.
