How to Use the Parlay Calculator

A parlay combines two or more selections into one wager. All selections normally need to win for the parlay to cash.

01

Enter Your Stake

Enter the amount you plan to risk. The calculator uses this amount to determine your potential profit and total return.

02

Choose Your Odds Format

Select American odds such as +150 or -110, or switch to decimal odds such as 2.50.

03

Add Each Parlay Leg

Enter the odds for every selection in your parlay. Use Add Leg to include additional bets or remove a leg you no longer want.

04

Review Your Potential Return

The calculator displays combined odds, estimated implied probability, potential profit and total return.

Understanding Your Parlay Results

Combined Odds

The calculator converts each selection to decimal odds and multiplies them together to determine the overall parlay price.

Implied Probability

This converts the combined odds into an estimated break-even probability for the full wager.

Potential Profit

This is the amount you could win above your original stake if every selection wins.

Total Return

This is the full amount returned, including potential profit and your original stake.
