This tool is for education and entertainment only. It does not place bets or guarantee outcomes. Always confirm final odds and payouts directly in your sportsbook app.
How to use this parlay calculator
Step 1: Choose your bet type
- Straight bet: Single leg only. The calculator uses the first row of odds and ignores additional legs.
- Parlay: Multiple legs from any games. All legs must win for the ticket to cash.
- Same game parlay: Multiple correlated legs from the same game. Math is the same as a regular parlay, but correlation can increase risk.
Step 2: Enter your stake
In the Stake amount box, enter how much you plan to risk on the ticket. The calculator uses this number to estimate payout and profit.
Step 3: Add legs and American odds
- Use Add leg to create as many rows as you need.
- Optionally name each leg (for example, Team A moneyline, Player B over 65.5 yards).
- Enter the American odds for each leg, such as -110, -120, +150, or +400.
- Click Remove on any row you no longer want to include.
Step 4: Review payout and profit
As you type, the calculator automatically updates:
- Total decimal odds: Combined decimal odds for the ticket.
- Equivalent American odds: The closest American odds that match the combined decimal price.
- Potential payout: Estimated total return if the bet wins, including your stake.
- Potential profit: Estimated profit only, excluding your original stake.
Step 5: (Optional) Estimate edge and house hold
If you have a view of what the fair odds should be for the total ticket, enter those in the fair odds box to estimate:
- Estimated bettor edge: Approximate expected value per dollar bet, based on your fair odds.
- Estimated house edge: The opposite of the bettor edge, representing the implied advantage for the sportsbook.
Build your ticket and estimate payout
Choose a bet type, enter your stake, and add legs with American odds (for example -110 or +150). For parlays and same game parlays, the calculator multiplies decimal odds to show total payout and profit.

Estimate edge and house hold (optional)
If you have a view of what the fair odds should be for this ticket, you can enter that here to estimate the bettor edge and the implied house hold. This is more advanced and optional.

Edge estimates are based on your fair odds input and the current ticket odds. They are only as accurate as your assumptions and do not account for correlation, limits, or market changes.
Parlay calculator FAQ
No. This is an educational tool only. It helps you understand how odds, legs, and stakes translate into potential payout and profit, but it does not connect to any sportsbook or place wagers on your behalf.
A straight bet is a single selection, like one spread or moneyline. A parlay combines multiple selections from different games into one ticket, and every leg must win. A same game parlay is a parlay where the legs all come from the same game, often with more correlation between outcomes.
Parlay math multiplies decimal odds for each leg. Every new leg increases potential payout but also increases the chance that at least one leg will lose. That is why long parlays have attractive payouts but are much harder to hit than a single straight bet.
If you enter a fair odds estimate, the calculator compares that to the current ticket odds and estimates expected value per dollar bet. A positive bettor edge suggests the price could be favorable to you. A positive house edge suggests the price favors the sportsbook. These are rough estimates and depend entirely on how accurate your fair odds input is.
Sportsbooks can factor in boosts, free bet terms, minimum and maximum odds, and correlation rules that this calculator does not know about. They may also round differently or cap payouts. Always treat this tool as an estimate and check the official payout shown in your sportsbook before you confirm any bet.
Many experienced bettors keep parlays to a small portion of their bankroll because parlays have higher volatility than straight bets. A common approach is to risk smaller units on parlays than on single game bets and only bet money you can afford to lose.
