Assumptions
Cash stake, independent legs and the odds you enter. No taxes, commission or bonus bets. Payout includes your stake; profit does not.
Same-game parlays
Legs from the same game are correlated, so multiplying their odds does not give a valid price. The sportsbook's own same-game parlay price applies.
How the parlay calculator works
Enter the odds
Type the odds for each leg. American odds (−125, +110), decimal odds (1.80) and fractional odds (5/2) all work – pick the format above the legs.
Enter your stake
Type the amount you are betting on the whole parlay, up to two decimal places.
Read the result
You get the parlay odds, the potential payout (stake included) and the profit (payout minus stake).
Behind it is one formula: parlay odds = decimal odds of leg 1 × leg 2 × … × leg n, and payout = stake × parlay odds. In the example, −125, +110 and −200 are 1.80, 2.10 and 1.50 in decimal odds. Multiplied together that is 5.67 (+467), so a $100 parlay pays $567.00. The full walkthrough is in the guide on how to calculate parlay odds.
2-team, 3-team and 4-team parlays
Every leg you add raises the parlay odds – and adds one more result that has to go your way. The table shows the same price on every leg with a $100 stake.
| Parlay | Parlay odds | Payout |
|---|---|---|
| 2-team parlay | +264 (3.64) | $364.46 |
| 3-team parlay | +596 (6.96) | $695.79 |
| 4-team parlay | +1,228 (13.28) | $1,328.33 |
| 5-team parlay | +2,436 (25.36) | $2,535.91 |

Moneyline parlays for NFL, MLB and other sports
American odds are also called moneyline odds. +150 means a $100 bet wins $150; −200 means you have to bet $200 to win $100. Choose American above the legs and the calculator converts each moneyline to decimal odds before multiplying.
The sport does not change the math. A parlay of NFL moneylines, MLB run lines or NBA spreads is calculated the same way, as long as you enter the odds you are actually offered for each leg. To convert a single price, use the odds calculator.
Build and analyze a parlay or accumulator
A parlay builder combines selections you supply; it does not need to generate picks. Add or remove legs above, choose the odds format, and compare the combined price and payout. An accumulator is another name for this all-legs-to-win structure. Decimal odds use the same multiplication as converted American prices.
For NFL football, MLB baseball or NBA basketball, enter the actual moneyline, spread or total price for each leg. A spread such as −3.5 or a run line of +1.5 is a settlement condition, not the odds: enter its offered price, such as −110. The math does not change by sport, and the calculator has no league results feed.
To analyze a ticket scenario, change a leg from Win to Loss or Void in Set results. This checks the payout under your selections, not the probability that the teams will win. For that separate question, use the parlay probability calculator with independent probability estimates. For an existing ticket with one outcome left, use the parlay hedge calculator.
Vegas odds and fixed parlay payouts
Use the actual offered prices for a Vegas-style moneyline parlay. Some parlay cards use a fixed payout schedule instead of multiplying the listed individual odds; their stated schedule controls. This independent parlay calc models price multiplication and does not reproduce a particular sportsbook’s fixed card or provide live Las Vegas lines.
Compare the offered payout, not just the number of legs
The same selections can pay different amounts at different quoted prices. Three legs at decimal 2.00 multiply to 8.00; three at 1.90 multiply to 6.859. With a $10 stake, the winning returns are $80 and $68.59. Comparing prices is meaningful only when the selections, settlement rules and available stake are the same.
Suppose, purely as a mathematical example, each of three independent selections really has a 50% chance. The all-win probability is 12.5%. At 1.90 per leg, expected total return is 0.125 × $68.59 = $8.57375 from the $10 stake, an expected loss of about $1.43. The larger possible payout has not removed the effect of the prices. Actual probabilities and correlations are not supplied by this calculator.
When multiplying is wrong: same-game parlays
The formula assumes the legs are independent. Legs from the same game usually are not – if a team wins big, the over becomes more likely, for example. Sportsbooks therefore set their own same-game parlay price, and that price cannot be found by multiplying the individual odds. This calculator does not price same-game parlays.
Frequently asked questions
Convert every leg to decimal odds and multiply them together. That is the parlay's decimal odds. Multiply by your stake for the payout, then subtract the stake for the profit.
Example: 1.80 × 2.10 × 1.50 = 5.67. A $100 stake pays $567, a $467 profit.
In this calculator a void leg counts as decimal odds of 1.00 – it drops out and the parlay is calculated on the remaining legs. Open Set results and mark the leg as void to see the new payout. Sportsbook rules vary, especially for same-game parlays.
A parlay needs every leg to win. If one leg loses, the whole stake is lost. If you want some combinations to pay even when a pick loses, look at a round robin.
