How to use this calculator
- Enter your total bet in the Stake ($) box, for example 100.
- Choose the Odds format your sportsbook shows: American, Decimal or Fractional.
- Type each leg’s odds in the Leg 1 and Leg 2 boxes with a sign, like -110 or +150. Use + Add leg for more legs, up to 12.
- Leave each leg on Win. Set it to Push if that game ended exactly on the number, or Void if it was canceled: either way the leg drops out and counts as odds of 1.00.
- Total payout is everything you get back, stake included. Profit is payout minus stake. Implied probability is the chance of every leg winning that the combined odds assume.
Example: step by step
- The Stake ($) box starts at 100.
- Leg 1 is -110. At -110 every $1 returns $1.909 (decimal odds 1.909).
- Leg 2 is also -110. The parlay multiplies them: 1.909 × 1.909 = 3.64 decimal odds, or +264 in American odds.
- Total payout: $100 × 3.6446 = $364.46.
- Profit: $364.46 − $100 = $264.46. Implied probability shows 27.44%.
In plain words: if both -110 picks win, your $100 parlay pays back $364.46, which is your $100 plus $264.46 profit. If either pick loses, you lose the $100. The 27.44% says how often both would have to win for this price to be fair.
Enter your stake and the odds for each leg to see what a parlay pays. The calculator takes American, decimal or fractional odds, handles 2 to 12 legs, and lets you mark any leg as a push or void. Results update as you type, and the link button saves your exact parlay so you can come back to it or send it to someone.
How parlay odds are calculated
A parlay links two or more bets into one ticket. Every leg has to win, and in return the payout of each leg rolls into the next. That is why parlay odds are multiplied, not added.
The cleanest way to do the math is with decimal odds, because a decimal price already includes your stake. Convert every leg to decimal, multiply them together, and multiply the result by your stake. That number is your total payout; subtract the stake to get your profit.
- Negative American odds (favorites): decimal = 1 + 100 ÷ the odds. So -110 becomes 1 + 100/110 = 1.9091.
- Positive American odds (underdogs): decimal = 1 + the odds ÷ 100. So +150 becomes 2.50.
- Fractional odds: decimal = 1 + the fraction. So 5/2 becomes 3.50 and evens (1/1) becomes 2.00.
The calculator does this with exact fractions rather than rounded decimals, then rounds only the final dollar amounts to the cent. If you want a refresher on reading the three formats, see our guide to how to read betting odds.
Worked parlay examples
Two-team parlay at -110 and -110
Each -110 leg is 1.9091 in decimal. Multiply them: 1.9091 × 1.9091 = 3.6446. A $100 stake returns $364.46, a profit of $264.46. Expressed as American odds the parlay is about +264. Bet the same two games as separate $100 singles ($200 staked) and you would profit $181.82 if both win, so the parlay pays more for taking on the extra risk.
Three legs mixing favorites and underdogs
Take +150, -125 and +110. In decimal those are 2.50, 1.80 and 2.10. The product is 2.50 × 1.80 × 2.10 = 9.45. A $50 stake returns $472.50, a profit of $422.50, which is +845 in American odds.
A parlay with a push
Say you bet $100 on -110, -110 and +200, and the +200 leg lands exactly on the number. At most books that leg is graded as a push and priced at 1.00, so the ticket becomes the two-team parlay above and pays $364.46 instead of the $1,093.39 the full three-legger would have returned.
Fractional odds
With 5/2, 6/4 and evens, the decimal prices are 3.50, 2.50 and 2.00. Multiplied, that is 17.50, or 33/2 as a fraction. A $20 stake returns $350, a profit of $330.
Why your sportsbook’s payout may be different
This calculator shows the payout you get when every leg’s price is multiplied exactly. Your ticket can come out a little different for several reasons:
- Rounding. Some books round each leg before multiplying. Treat -110 as 1.91 and the two-team example pays $364.81 instead of $364.46. The gap grows with every leg.
- Fixed payout tables. Some shops and parlay cards pay a set price by number of teams instead of multiplying. A two-team payout of 13/5, for example, returns $360 on $100 rather than $364.46.
- Same-game and correlated parlays. When legs depend on each other, books price the combination with their own model, so the result is not the product of the individual prices. Our look at same-game parlays explains why.
- Payout caps, boosts and promotions. A maximum-payout rule can cut a long parlay short, while a profit boost or parlay insurance changes the return in your favor.
- Price movement. The odds on your ticket are the ones you locked in. If a line moves after you bet, the payout does not change.
Every leg also carries the book’s margin, so a parlay stacks that margin once per leg. Our explainer on vig, juice and hold shows how that works.
What push and void do to a parlay
A push happens when a result lands exactly on the spread or total. A void usually means the game was canceled, postponed past the book’s deadline, or a listed player did not take part. At most sportsbooks both are handled the same way inside a parlay: the leg drops out and is priced at 1.00, so it neither adds to nor subtracts from the payout. A three-team parlay with one push becomes a two-team parlay; a two-team parlay with one push pays like a single bet on the remaining leg; if every leg pushes or voids, you get your stake back.
House rules vary. Some parlay cards grade ties as losses, and some books treat a void leg differently in same-game parlays, so check the rules before you bet. Our guide to parlays, teasers and round robins covers the common variations.
What implied probability means here
Implied probability is 1 divided by the parlay’s decimal odds. For the two-team -110 parlay it is 27.44%. That is the win rate you need to break even at this price, not a fair estimate of your chances. Each leg’s price includes the book’s margin, so if both -110 legs are genuine coin flips, the real chance of the parlay winning is 25%, below the 27.44% you would need to break even.
Parlay calculator FAQ
How do I calculate parlay odds by hand?
Convert each leg to decimal odds, multiply them, and multiply by your stake to get the total payout. Two -110 legs are 1.9091 × 1.9091 = 3.6446, so $100 returns $364.46.
What happens to my parlay if one leg pushes?
At most books the pushed leg is removed and priced at 1.00, and the parlay is paid on the remaining legs. Set that leg to “Push” in the calculator to see the reduced payout.
Is there a difference between push and void in this calculator?
Not in the math. Both are priced at 1.00. They are listed separately so your ticket matches the way your sportsbook grades it.
Why doesn’t my sportsbook’s payout match the calculator?
The usual reasons are per-leg rounding, a fixed parlay payout table, same-game pricing, a maximum-payout rule or a promotion. The calculator shows the exact multiplied price, which is a useful benchmark for spotting a short payout.
How many legs can I add?
Between 2 and 12. Each extra leg multiplies the payout and lowers the chance of the whole ticket winning; twelve legs at -110 return about $23,438 on a $10 stake.
Can I save or share a parlay I’ve entered?
Yes. Use “Copy link to this parlay.” The link stores your stake, odds format, every leg and any push or void, and opens the calculator exactly as you left it.
